 What version of a firmware at the moment?

Hi, It took me days to figure mine out. The solution may be a setting on the monitor.
I put my smart 4k TV in “game” mode and turned off CEC, and it worked. keep trying different settings, color and picture. Also, try using another monitor in an hdmi port if you have one on your card.
good luck.

 What version of a firmware at the moment?
From DenisDA

@johncasey37 yeah, HDMI works, but sadly I have only 1 HDMI port on my graphics card … Thus I would like to be able to change the output signal to be YCbCr 4:4:4 even with the adapter.

P.S.: I’ve tried the display settings to hard, it’s annoying… The display supports YCbCr 4:4:4 and when connected directly via HDMI, AMD lets me use it.

I’m having an issue similar to @li7in6 it seems.

I’m using multiple Eizo FS2434 (Capable of YCbCr 4:4:4) and the display connected via CAC-1170 can’t use pixel format and thus don’t use YCbCr. The display connected via HDMI can. If I set the monitor to YCbCr 4:4:4 the display gets greenish since it’s receiving RGB.

My system specs:
– AMD R9 280 (drivers: 16.7.3)
– Windows 10 Pro 64bit

I’ve sent a mail to [email protected] half an hour ago or so, too. Maybe a new firmware actually helps.

Hopefully you can come up with a solution.

Thanks in advanceFrom Thranos

 
I answered this yesterday on my phone but then it asked me to log in and m entire response was lost.

To summarize:

From AMD support, the AMD drivers do not allow the use of the “Pixel Format” options under additional settings when a display is plugged in through a Displayport. Those options are only available with an HDMI connected display. I have confirmed this by plugging both a displayport and HDMI monitor into my GPU and the “Pixel Format” options become available, however you are only able to select options for the HDMI connected display.

This means for a DisplayPort connected monitor/TV there is no user-level ability to select RGB/YCbCr or 4:2:0/4:2:2/4:4:4 chroma sumbsampling settings at the display adapter. According to AMD support the display “”””SHOULD”””” output the best resolution, bit depth, and chroma settings that it can on it’s own.

As you and I have discovered this is not the case.

In my own testing I have discovered that the display detects a 4096×2160 input no matter what you have selected as the output resolution on windows control panel. The display is a 3840×2160 native resolution and when 3840×2160 is selected in control panel, the display outputs a correct aspect ratio 3840×2160 image with no overscan but still is detected as a 4096×2160 signal according to the display.

I have discovered a temporary work-around to get a true 3840×2160 4:4:4 chroma 8 bit per color image on my setup. This involves cycing the “HDMI UHD Color” setting off then back on again for my TV. The “HDMI UHD Color” setting is what enables the TV to output a full 4:4:4 4k@60hz image. Once “HDMI UHD Color” is turned back on the TV will be properly displaying a 4:4:4 chroma image and the display will correctly be detecting a 3840×2160 input unlike the 4096×2160 situation described in the paragraph above.

This is not a permanent solution however as any time the display is turned off, or the resolution is refreshed (like when starting a game or any other program that has resolution control). The TV/GPU will revert back to the detected 4096×2160 4:2:2 output until you go back and cycle “HDMI UHD Color” off then back on again. Especially inconvenient considering when cycling “HDMI UHD Color” off then back on the TV has to restart each time. This work around is not to be considered a permanent solution because of this.

This is my experience with a Samsung TV. Different models of TV my require a different work-around.

Hope this helps.

Got 7.26, but it didnt help.@johncasey37 yeah, HDMI works, but sadly I have only 1 HDMI port on my graphics card … Thus I would like to be able to change the output signal to be YCbCr 4:4:4 even with the adapter.P.S.: I’ve tried the display settings to hard, it’s annoying… The display supports YCbCr 4:4:4 and when connected directly via HDMI, AMD lets me use it.From Thranos

 
7.26 did not solve my issue either. It did however induce a intermittent flickering across the screen. Not a huge deal, but distracting. I reverted back to 7.23 firmware to correct this issue.

 At least I’m not having this issue … Yeah I’ve read about your workaround. Doesn’t work for me. MonInfo shows the capability to use YCbCr on all three monitors. This said, there should be some way to use it on DP, too. To make things even worse, you can see on https://pcmonitors.info/articles/correcting-hdmi-colour-on-nvidia-and-amd-gpus/ that AMDs output signal differs for YCbCr vs RGB. It differs on nvidia cards too, but its not as bad as using AMD …

From Thranos

• Open Custom Resolution utility
• Select the display in question.
• In the “Detailed Resolutions” box delete all resolutions other than 3840×2160@60hz and 1920×1080@60hz
• Select the 3840×2160@60hz option and click “Edit” under “Detailed Resolutions”
• In the new dialog select “Timing > Automatic LCD Native”
• Ensure that the correct 3840×2160 resolution is input under “Active”
• Under refresh rate change to 59hz (~584 pixel clock)
• Click “OK” then click “OK” again to exit the utility
• Select the “restart.exe” or “restart64.exe” executable according to your OS
• After the restart is done and you correct all your scaling and resolution settings back to the way you want them the display should be at a 3840×2160@60hz (59hz actual) and it should be displaying at 4:4:4 chroma subsampling.
• Doing this also allows the resolution to be reverted back to by default so you do not lose 4:4:4 chroma when the TV is switched off or when resolution is refreshed by a program.

Let me know if this helps.

Also thank you Thranos. You gave me the idea.

I had used Custom Resolution Utility to overclock my Samsung monitors to 75hz and seeing it in your link gave my the idea to slightly underclock the TV to get the desired results. It worked, now I hope this, or something similar, works for you.

will send you an email form [email protected]

I have the same problem… sent to me too please

i have a x900a from 2013, i use fury x and i need to change pixel format to 4:2:0 can you help me please?

email send thru [email protected]

Hi Revenger,

I advise you to use HDMI 1 port on the TV and make a custom resolution on the crimson driver for 3840x2160p with timing standard set to CVT-Redeuced Blanking. Please also check your HDMI Cable is capable of doing 4K at 60Hz or HDMI 2.0 or 18Gbps

I checked all the cables. This effect is observed only when connected via cac1070. Even at a frequency of 30 hertz. TV is divided barely noticeable strip and one of the other little lighter.
Just sometimes the screen becomes covered in thin green stripes. If you connect a 4K @ 30hz hdmi-hdmi, the picture is normal.

sorry i missed your message before :-S
i will send you an email from [email protected] with firmware update.

just saw we already fixed this over email on 18-074-2016 🙂

Hi Usernamegoeshere,

Most 4K screens do not genereate a very good picture in 1440p, most likley it will even look better in 1080p. However please do check with Vizio if such resolutions are actually supported.

Please use HDMI port 5 on the TV.
TV’s often work best by making a custom resolution in your case 2560x 1440 p with Timing Standard set to CVT-Reduced Blanking.
Please turn off GPU Scaling.

I’m having this same problem and tried your solution. Though the television seems to accept this resolution, starting the game I’m wanting to play gives me a “No Signal” screen, so it’s even more useless than just playing the game in a small square in the middle of my screen.

Good day mjnichol,

What screen do you use ?

I use a SEK-3500 connected to a Samsung HU8550, making it equivalent to a JU8500/JU9000/JU9500.

I’ve tried RGB and 4:4:4 @ 24Hz and 4:2:0 @ 60Hz and only have 8bpc as an option.

I’ll try the firmware update that was sent to me today to see if that helps.

So, the updated firmware doesn’t help. Still no option other than 8bpc. When I connect HDMI directly, I see 8bpc and 12bpc. Please let me know if there is anything else you can suggest, or if I should return it to amazon.

Hello mjnichol,
it looks like the system/adapter is not able to read the EDID info from the TV in proper manner and therefore does not allow you to do certain settings. Does the TV have and HDMI2.0 input so you can try without the SMart Hub ?

By SmartHub, I’m assuming you mean the OneConnect box (SEK-3500). No, the box completely replaces all electronics on the TV (other than the panel), so all original inputs on the TV are no longer active.

No other devices I’ve used seem to have any problem determining the capabilities of the TV, and I’ve grabbed the EDID via the HDMI output myself and looked at it, and don’t see any obvious problems. EDID shows that the set accepts 30-bit and 36-bit signals.

Have you tested your adapter with nVidia + a Samsung J-series TV?

Unfortunately not have been able to test it with SEK-3500.

I am suspecting the Pixel Clock being too high. Some TV’s can do native Pixel Clock of around 594 MHz, however DP1.2 only allows up to 540Mhz. With “normal” graphics drivers you can often  not do such setting but with program like CustomResolutonUltility (CRU) you can. Jus tmak e a cusotm resolution for 380x 2160 at 60Hz prograssive with Timing Standard at CVT-RB (Reduced Blanking) and pixel clock set to 539MHz. 
http://www.monitortests.com/forum/thread-custom-resolution-utility-cru

I don’t think you fully understand the problem. I’m not having a problem getting 2160p at 60 Hz. My problem is getting a bit depth higher than 8-bit (i.e. 10-bit or 12-bit). As far as I know, CRU doesn’t let me pick a bit depth, unless it’s been added recently.

Can you confirm that I can set 2160p @ 24Hz with 10-bit or higher using CRU? If so, I’ll try it.

I’m a little skeptical, though, because I would assume 2160p @ 60Hz at 8-bit would use a higher pixel clock than 2160p @ 24Hz at 10-bit.

Hi mjnichol,
You are right CRU does not have Color Depth setting, but it does “overwrite” the Nvidia driver settings, which does help in some cases. 
If you choose 4k at 30Hz (or lower) you should be able to run 4:4:4 in 12Bits BPC.
Normally Graphics driver will blank out the option to change the 8 Bit BPC but when the frequency is lowered it should activate again so it can be changed …
Did you check with Nvidia on this already ?

As mentioned, I can run 4:4:4 at 12bpc at 24Hz if I connect directly to the HDMI output on the card, thus, I don’t think nVidia will be willing to help me, as the problem only happens when I use your adapter.

Have you tested that the adapter works with 12bpc with nVidia (with any display)?

got this from the technical document

Thanks, but I’m not sure how that helps my particular situation. I’m going to return the adapter to amazon as it shouldn’t be this hard to get it to output 10 bit or higher on the most popular brand of video card.

I got some feedback from R&D and they state that the Adapter needs to be connected to the TV/Monitor directly. Placing another HUB/Converter in between will most probably disrupt the signal.
Sorry i do not have a better message for you but it will most probably not work with your setup 🙁
Sorry for the inconvenience.

It is connected to the TV directly. The SEK-3500U is not a hub or converter. It’s connected to the panel using a special Samsung OneConnect cable (not HDMI, etc.). So, as far as external devices are concerned, they are talking directly to an HDMI port on the TV.

Many new Samsung TVs have no HDMI ports on the TV itself and use this type of box to separate the inputs from the TV panel.

Same issue here. Can not get 12bpc 24Hz connected to SEK-3500, thought it was an nVidia driver problem – nope, it’s a Cub 3D problem. Works fine over HDMI.

it is not a resolution issue, but an incompatibility issue with the SEK-3500, somehow the Adapter and the SEK-3500 ahve a problem with each other … Having said that many converted signals have a problem when connected to another converter/hub type of device like SEK-3500.The issue is escalated to R&D and Factory and i hope they will find a solution for it .. Will keep you posted as soon as i get feedback.

That’s simply not true. For all intents and purpose the SEK-3500 is the TV – it is NOT a hub or converter.  Also, many other users complain they can’t get anything above 8bpc at frequencies below 30Hz, regardless of the model display.

Sorry if i did not expres myself properly, certainly not my intesion. We are talking about this SEK-3500 One Connect Evolution Kit right (as Samsung calls it) ? 

We have had more reports from users about this not working in this combination PC>Adpater>SEK3500>TV
Settings you are talking about also depend on what the screen can handle, what the Graphics can output, if the Graphics driver allows you to do neccesary settings, the manner in which the TV offers th EDID info to the system etc. many things the adpater has very little to no influence on. This does of course not mean we do not take such issue seriously, we most certainly do. We have send samples of our CAC-1070 and CAC1170 to Samsung so they can test in order to help us detemine where the problem comes from and so help us solve this issue. No solution so far, but working on it …
Will keep you informed as soon as we have feedback on the topic

Like you mjnichol i also bought this in the hopes hdr would work as advertised im using a 1070 contacted nvidia asking if this was somehow a displayport problem/limitation and there are no limitations for that. the official reply i had from club3d is that hdr doesnt work at all and they  hope  it may work in 3 months.
4k@60hz is no problem hdr just doesnt work the product page is just very misleading
this does not feel like a finished polished product but at best a beta phase.

Hi LittleStereo,

Could be a number of things …
It normally work best to have the Screen via the Adapter as secondary screen.
Please disable CrossFire.
I dont have feedback on the 10 meter cable, it looks fine spec-wise.
Some TV’s can do native Pixel Clock of around 594 MHz, however DP1.2 only allows up to 540Mhz.

Hi Carbert,

Thanks for the info. Issue is escalated to R&D and Factory. As soon as we get feedback we will update you.

Hi Theremin,

Yes that UHD color most probably need to be enabled for the screen to do 4k at60Hz in proper manner.
Please try making a custom resolution for 3480×2160 at 60 Hz, you might need program like SwitchResX for that on the MAC.

Hi,

I tried with that setting on and by creating a bunch of different custom profiles with SwitchResX but none of them worked. I only got flickering occasionally but other than that the screen didn’t recognize the signal.

I tried with CVT, CVT-RB, CVT-RB v2 and whatever other settings SwitchResX has. I also tried with both 60 Hz and 50 Hz but no difference.

Anything other I could try? Could this be a compatibility issue with the screen and CAC-1070?

I am sorry but we have no experience with that particular Screen, so cannot really help with that. It could be that the system/adapter is not able to read the EDID info coming from the screen (although that is not really a problem with any other LG Screen i know of). But than again that custom resolution you make will just “force” that signal to the screen so if the screen can handle it, it should give a picture. With TV’s the CVT-RB is important, for Monitors not necessary, can just be at “Auto” or somthing like that. 
HDMI2.0 directly from the card to the Screen does work ?

HDMI directly from the card to the screen works, but only at 30 Hz because macOS doesn’t yet support 60 Hz from HDMI, hence the need for the adapter.

I will try again to see if I can force it to 60 Hz. Unfortunately this screen model has very limited options in the settings.

your  MAC does support 4k 60 Hz from the DP output ?
Normally only MAC’s from MID 2013 or newer do that i read online …

It should support it, that’s what the seller is promising. This is a new card flashed to support Mac boot screen.

i am asking because you said that the HDMI2.0 output of the card is not working at 4K 60Hz because of the OS … why would the DP output work at 4K 60Hz with the same OS ?

It is my understanding that none of the current Mac hardware is equipped with HDMI 2.0 and perhaps because of that the OS isn’t capable of HDMI at 60 Hz. DisplayPort 1.2 is supported at 60 Hz. This is the whole point of the adapter, because currently Mac users can only get 60 Hz 4k with DP.

And the LG screen supports 60 Hz only through HDMI.

Weird, I did a complete reinstall of the OS and it started working by itself. I didn’t even have to use SwitchResX. I guess there was something off in the OS.

good to hear it works for you now 🙂

Hi compalalaska,

That is odd, we did receive your message and is answer from [email protected]

* Please make sure the TV is updated to latest software/firmware.

* When connecting a HDMI 2.0 device, HDMI Color Subsampling needs to be enabled to support 4K resolution at 60hz.

To enable/disable HDMI Color Subsampling:

1. From the Inputs menu, tap HDMI Color Subsampling. The HDMI Color Subsampling menu is displayed.
2. Find HDMI input that your HDMI 2.0 device is connected to and swipe the switch right to enable and left to disable HDMI Color Subsampling.

* Please make sure you HDMI Cable is capable of 4K at 60Hz or 18Gbps.

With setups like yours is normally works best to make a custom resolution for 3840x2160p at 60H with Timing Standard set to CVT-Reduced Blanking (RB).

Removed and reinstalled the 8/31/2016 version of Intel HD Graphics Drivers, version 15.40.28.4501 for win10.
No more flickering, will stay on 7.26 then.

Good that it works for you again.
And yes please be carefull with those auto updates …

The interesting thing is that win10 had auto updated the 520 driver while I was on 7.23 and did it again AFTER I updated to 7.26 and manually installed older graphics drivers. Net result was no flickering though, so I’m happy. No other problems either, the CAC-1170 gives me 4k/60hz on a 50 inch Panasonic TV, from the Skylake NUC, which has only 4k/30hz over hdmi, but 4k/60hz on the mini-dp.

What often works best for setups with TV’s is to make a custom resolution for 3840x2160p at 60 Hz with Timing Standard set to CVT-Reduced Blanking (RB).

For MAC OSx you will need a program like SwitchResX to be able to do that setting for the Timing Standard.

Please make sure your HDMI cable is capable of doing 4K at 60 Hz. You said you have a “High Speed” cable, but that only garantees 3840×2160 at 30Hz … the “premium high speed”

Versions should be made for 3840×2160 at 60Hz. Don’t get me wrong here, I am not saying your cable is not good or that is not able to do it, but please check and make sure.

A Premium High Speed Cable no longer then 3 meters / 10 ft is preferred. Does not have to cost all that much, in the US you can already buy our Certified cable for about 17 USD.

When running in 3840x2160p at 60Hz at 4:4:4 you will need to set the BPC to 8Bit (if that is not done by the Graphics Software automatically).

Please note I am talking BPC not BPP.

Hi Cabouret,
Well if it all works well on the MacBook Pro at least we know all the parts are working.
With regards to the Mini MAC, you amde a custom resolution for 3840x2160p at 60Hz with Timing standard set to CVT-Redeced Blanking (RB), saved it and then after rebooting system selected it with TV connected and on?

Hello AlKappacinno,

It indeed often works best for setups with TV’s is to make a custom resolution for 3840x2160p at 60 Hz with Timing Standard set to CVT-Reduced Blanking (RB).
Most TV’s need to have “UHD Color” manually set to enable and/or “PC-Mode” or “Game-Mode” set to enbaled.

With regards to AMD DrIvers:

I think Driver version 16.8.3 is overall working best. I know AMD made many small driver updates after that, however all aimed at RX400 series and non that I know of for R7/9 200 or 300 Series. I do hear end-users with R7/9 200/300 series Cards reporting that 16.12.1 also works quite decent for them. Did not test that myself yet. Please uninstall the current Graphics driver and all related Graphics software like Afterburner/GPU-Z or whatever graphics related software you might have installed.

Best way to remove Driver Software is to boot Windows in Safe mode, so the registry can also be cleaned. When you system does not allow you to do that, you can also use a program like DDU to remove such software: http://www.wagnardmobile.com/DDU/

Reboot and manually download and install 16.8.3 graphics driver (don’t let auto installer from Windows do that)  You can find that here: http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows%2010%20-%2064&rev=16.8.3

Please do try first without receiver in between first, just to make sure it works.

Hi Mikem87,

For Fury X i think driver version 16.8.3 works best.
I did get end-users reports that Driver version 16.12.2 also works well but did not test that myself yet.

Good day rerry182,

For setups with TV’s it normally works best by making a custom resolution for 3840×2160 at 60 Hz with Timing Standard set to CVT-Reduced Blanking (RB) for TV’s (for Monitors that can remain on “auto”).

Make sure the input on the TV is HDMI 2.0 (or capable of 4K 60Hz), often not all HDMI inputs are …

Make sure to use a HDMI cable capable of 4k at 60Hz preferably a certified one and not longer than 3 meter (max 5 meter)

Sometimes it does help to make a clean driver install. When using upgrade-feature to update drivers, often “older” files remain in the registry of the system and those can be “in the way”. UHD Audio driver is also included in this driver pack.

With regards to drivers for AMD.

I think Driver version 16.8.3 is overall working best for R9 Fury X. I know AMD made many driver updates after that, however all aimed at RX400 series and non that I know of for Fury X. I do hear from end-users that 16.12.2 also works quite decent for them. Did not test that myself yet.

Thanks… I will try everything that you said,…
later this have more things thats I could do?
My tv have the same problem of the older vizio, only 4:2:0
and I need to set this but I can’t … I need a way to do that…
thanks

not work for me

Hi Stelios,

When in resolution 3840×2160 at 60Hz in 4:4:4 the BPC needs to be set at 8Bit.
(Note: BPC is not the same as BPP that will probably still give you 32bit)
Setups with TV’s normally work best by using a custom resolution for 3840×2160 at 60 Hz with Timing Standard set to CVT-RB (Reduced Blanking).

Hi MST1407,
To be honest, I do not really care about the 4K resolution. I mostly care about the 10bpp. So even if I set the resolution to 1080p and the freq to 30Hz I do not get bitdepth more than 8bits. According to the HDMI standards this is possible even using the HDMI 1.4, not even the HDMI 2.0…   The bpc thing was a typo.

https://insights.club-3d.com/thread/cac-1070-firmware-download/

Hi All,

A Displayport 1.2 output has 21.6 Gbps of Bandwidth and an HDMI 2.0 has 18Gbps of bandwidth. So with the CAC-1070 / CAC-1170 the signal needs to be no bigger then 18Gbps.
3840×2160 at 60 Hz in 4:4:4 8 Bits BPC = 17.82 Gbps
3840×2160 at 60 Hz in 4:4:4 10 Bits BPC = 22.28 Gbps, Will not fit !
3840×2160 at 60 Hz in 4:4:4 12 Bits BPC = 26.73 Gbps, Will not fit !

If your screen is telling the system it can do 3840×2160 in 4:4:4 the AMD driver will most probably automatically switch to 8Bits BPC. It is indeed not prctical that you cannot chose to switch to 4:2:2 or 4:2:0 so you can up the BPC but i cannot help you with changing the AMD Driver :-S 
You will probably need a separte program to be able to do that ..

With regards to drivers for AMD. I think Driver version 16.8.3 is overall working best for R9 series. I know AMD made many driver updates after that, however all aimed at RX400 series and non that I know of for R7/9 200/300 Series.
I do hear end-users with R7/9 series Cards reporting that 16.12.2 (or later) also works quite decent for them. Did not test that myself yet.
Also please make sure the driver has a clean installation. WHen using an upgrade feature, often old files remain in the registry and thos can actually be “in the way”.

When done please make a custom resolution for 3840×2160 at 60 Hz with Timing Standard set to CVT-Reduced Blanking (RB).

I will have [email protected] send you an email with link to latest firmware.

ok. I’ll try that this weekend and update if issue persists, thank you.

Just wanted to say I did what you said, updated to latest drivers on a clean install, and updated the firmware. Played Resident Evil 7 and GTA V at 4K 60Hz with crossfire enabled and disabled in separate instances and have not had any issues so far.

Thanks!

good to hear it even works well with Crossfire, thanks for the feedback 🙂

I would say undo that scaling thing you did … and i will ask [email protected] to send you latest firmware for the adapter …

Sure i will ask [email protected] to send it to you

[email protected]From MST1407

 Sorry, not valid email!!!!
[email protected] – Valid mail

sorry yes thanks

Hi DenisDA,
Latest firmware you already have received 11-03-2017 by email from Club3D support. That is the 0x46.

Id also like the newest version as im sure others will to why not make a support page for the cable so people can just look what the latest firmware is and download it?.
feels like begging for updates thank god nvidia and others do it this way also i wouldnt mind a changelog see whats new or fixed as i bought this cable for specific reasons as promised on the page you have and none of those features work so that would be great to see if there is progress or im kicking a dead horse here.

Hello HellsAngel,
No need for begging, just drop an email to [email protected] and you will get it.
The reason why we do not post the Firmware online is that more often than not, the firmware is not the solution to issue people are having.
I aksed support to send to you, you should receive that today.

But you can downgrade if it doesnt work, keep older versions on the support page granted you make one and a nice changelog that all seems soo much better then constantly have to guess when there is a new firmware and if we please please can get it.I did receive it but how does it go next time i have to again ask for it? this seems easier for both user and support to just put it on a page just have to upload it once instead of god knows how many times. Everything you update firmware with has a risk but you could add a disclaimer hopefully you do something with this feedback it shouldnt be this difficult to get and see when or if there is a new firmware.

Thanks for the feedback

I was successfully using a CAC-1173 cable with a Samsung UHD TV until the last MacOS Sierra up-date. Very very very, annoying… thanks Apple.

Di you try making a custom resolution for 3840×2160 at 60Hz with timing standard set to CVT-Reduced Blanking ? You can do that with a program like SwitchResX …

Thanks for the answer.. yes last night I tried to do so and it works!
Before the update this setting was not required but well.. ok.

I’ve had some problems to make the custom resolution to install properly also with SIP disabled.. the only way to solve the issue was to create a new user account on my MBP and make all the SwitchResX setting from there.. strange behavior but well… ok.   : )

Good to hear you got it working 🙂 and thanks for the feedback

i will have support email you the latest firmware, however i am not so sure it will help you. 
What Graphics Card is inside or what CPU (in case it is integrated graphics) ?

Hi,
Thank you! I will check as soon as possible.
It’s Nvidia GTX980M. I forgot to mention that 1080p resolution works for me, but when I switch to something higher display turns off for couple of seconds and then sets 1080p again. I could set 2160p 59hz in nvidia control panel but it worked only once.

Hi,
I checked a new firmawre that you emailed me. Resolution works fine, DP outputs 2160p 60Hz but sound is weird. It’s crackling. Is there a reason why it behaviours like that?

The UHD Sound driver is included in the Graphics Driver Pack.

Especially when using the upgrade feature to update drivers can give issues, because old files can remain in the registry of the OS and can be “in the way”. Please make a new clean driver installation to make sure that part is ok.
Please uninstall the current Graphics driver and all related Graphics software like Afterburner/GPU-Z or whatever graphics related software you might have installed. Best way to remove Driver Software is to boot Windows in Safe mode, so the registry can also be cleaned. When you system does not allow you to do that, you can also use a program like DDU to remove such software: http://www.wagnardmobile.com/DDU/  

Download and install latest available driver for your device.
You might need to reboot ones or twice during this process.

Hmm, I did everything that I could but it hasn’t provided any positive results 🙁 is there no other feedback recently?

Sorry L24 not really no.
Did you try already loading a restore form before that lupdate that messed up your settings ?

Ok, I managed to got it work. I can only push 59Hz but it’s only 1Hz difference 😀
Here’s my Custom Resolution Utility settings:

Hi L24,

Good to hear and thanks a lot for the feedback.

Hi Seppok,
I am quite sure your problem is the fact that the Kepler based GPU’s (or older) are not really compatible with the Active Adapters converting DP 1.2 to HDMI 2.0.

That’s what I thought. I checked and the TV says 1920×2160@60hz. I requested the newest firmware for the adapters because I have nothing to loose. This is annoying because it almost works and I think I read somewhere that somebody had success with a GTX 780 or some other Kepler based card.

The HP GT 730 spec sheet says it outputs 3840×2160 60hz, CVT-RBv1/v2 (8.29M9R), SMPTE 274M from the DisplayPort. It is hard to understand how this signal differs from a signal output by a Maxwell card…

Unfortunately Nvidia has not explained that to me either :-S
Anyway since the EDID info does nto come thrue correctly (1920×2160@60Hz is not correct), i advise you to make a custom resolution for 3480×1260 @ 60 Hz with Timing Standard set to CVT-Reduced Blanking.

Hi TTY,

I removed the extra postings that did come trhu somehow !?

To my knowledge there is no HDMI2.0 to DP1.2adapter available in the market currently.

Our R&D has had a project open to devellop this product for about 1 year now, but we have not seen a product from this even on the reaodmap for the mext 6 months (yet).

So the best we can do to convert HDMi to Displayport at this point is:

CAC-1330 = HDMI1.4 to DP1.1

Hello ost,
I will ask [email protected] send you an email with latest available firmware.
Combination with GTX 1060 should work. 

In general:

Thanks MST1407.

First an issue with the updater. It could not find the adapter as long as I had a main DP monitor plugged in (my main screen). I had to unplug all except the CAC to get contact at all. Maybe this is worth putting down in the instructions.

2nd, I’m afraid that this firmware didn’t fix the problem. I also tried removing all other monitors

Hi ost,
It is indeed true that it normally works best when the screen connected via the adapter is set as secondary screen.
Active adapters are sensitive to other (espcially) active devices such as MST HUbs active Cables, other adapters, CrossFire / SLI configurations. 
What is your system configuration ?

Did you try already a clean drive installation ?

Some updates to this case (not solved yet)
I tried to update to latest drivers (to 384.76) but the blurred image is still the same.
I have also tried to make some testpatterns to reveal 422 or 420 color encoding, but there is no sign of this encoding being used. This looks more like some horizontal filtering or sharpness setting gone bad.

Also, I have tried it with a R9511 LCD controller board ( http://www.chiyakeji.com/content/?628.html ) and it seems to work nice there. The difference between the R9511 and my TV is that the  R9511 only give out 128 bytes of EDID, but the TV does full 256 byte EDID with CEA861 block. I don’t believe the issue is caused by the TV, since it will be seeing the same signal on both the adapter and direct.

I am very aware this may be a Nvidia driver problem. The driver does give different choices of color endoding depending on DP+adapter or direct HDMI, even if they show same EDID, but I guess this must be due to the physical attributes of the DP port vs HDMI and not related to EDID at all.

I will dig out a few optional boards, including older Nvidia and ATI boards and compare.
I will be back with more results later.

Thanks a lot for feedback, much appreciated.

I have been using the CAC-1170 model (FW 7.26) on and off with a Skylake NUC connected to a Samsung 40″ JU7000 TV. I just noticed that with the most recent Intel video driver, (custom resolution set with CRU, CVT reduced setting as recommended) HDMI audio doesn’t work properly, and there is some on-off flickering. Upon reboot, no audio output is found, until I use the reset tool of CRU – then I have HDMI audio until the next reboot. Could you send me a newer FW to see if it resolves these issues? Thanks!

Hi Boardlord,
Sue i will ask [email protected] send you an email on this right away

Hi!
I haven’t received the firmware yet…

that is not good, very sorry about that 🙁 
Will do again right away.

New information on my testing here. It appears as if the CAC-1070 does mess with colors, as if it was doing some UYV conversion internally.

I have now got my own FPGA driven displayport output wich I am 100% sure is driving pure 8 bit RGB into the CAC-1070, but the output colors are not correct, not even when driving 4k 30Hz. The green details are faded like the flickr link shown above. Also a red/blue chroma test image proves that there is definitely a 4:2:x conversion somewhere inside the CAC, and a 4:4:4 up-conversion later in that path. This messes badly up the 4k60 signal for computers. This won’t be noticable on UHD bluerays, as all blurays are already 4:2:0.

If you have a new firmware to try to resolve these issues, please email it to me and I will run tests. I really want this to be fixed.

My apologies! This is not completely true. This seems to be an even more complex issue. The CAC-1070 gives correct colors with 30Hz if I use a different HDMI receiver. Yet again, I need to get back with results when I know if its my TV or its EDID that causes the problems.

Some more feedback on this issue. I ran a more extensive test here and the conclusion is that the problem is NOT related to the CAC-1070 at all.

-When running a plain 1080p Nvidia GTX1060 HDMI directly to a Samsung UE43KU6075U tv => 4:4:4 chroma test (alternating horizontal red/blue pixels) is super crisp (even at 4k60)

-When outputting a 1080p signal from my project’s DP (or Nvidia DP) port via a DP->HDMI adapter (club-3d HDMI2, OR any old HDMI1.4), and splitting to two outputs using a Kramer VM-2HN, the Dell monitor is fine but the Samsung tv is blurry.

So I know this is not caused by any EDID parameters (I did try to fake it, no change).

I also tried to tweak my modline parameters on DP output to match the requested HDMI timing, but no difference there either.

The question remains, why does the Samsung see those signals differently and turn some crappy parameters on for the one sourced by the adapter?

indeed, you aksed them ?

What version of OS are you on now ?

I’m still on Sierra (10.12.6)

Hi michaelm,

That should work.
Did you check if the TV is still on “enhanced mode”?
Also we have heard of users needing to make a clean install of the SwitchResX version or even making a new user …

so this is how i think i got 3840×2160 at 60hz working. i have extended desktop and my tv is the primary desktop and my laptop with intel hd 4600 is secondary. So tv is 3840×2160 and laptop is 1080p.
i did the custom display thing but where in the intel hd 4600 graphics panel it says scaling i choose the last box that says “centre the picture?”,not the first one that says “keep the scaling”. My sony 65 tv still informs me its 1080p but windows and intel says 3840×2160.

thanks for the feedback 🙂

Hello gosheto,

Sorry but your GTX770 is a Kepler GPU Graphics card and those  do not work very well together with active adapters like the CAC-1070.
You could try with clean driver install and making a custom resolution for 3840×2160 at 60Hz with Timing Standard set to CVT-RB for use with a 4K TV.
