Hi Xinrag, most of our testing has been done with Hawaii (290/ 290X) and Fiji (Fury X/ Nano) cards. Earlier GCN cards like the Tahiti based 7950 should work but have not been through extensive testing. 
Which driver version are you using? And have you tried creating a custom resolution in the driver interface? 
If that’s not working, there is a firmware update available for the 1070/ 1170 which enhances EDID reading and compatibility. Can you send us a short email at [email protected] or leave your email address here than our support team can forward you the new firmware + instructions for update. Thanks!

Hello RoyalKing,
I was using the amd catalyst 15.11.1 beta driver and after that the the “Crimson Edition 15.2” (Display Driver version 15.30.1025.1001) which is atm the latest (searched on http://support.amd.com/en-us/download for my hd7900 series card).
Right now I have not tried custom resolitions. I will send you an email now…
Best regards, Stephan

Hi!
Very strange, interesting… meanwhile I have installed amds “Crimson Edition 16.1 Hotfix” and shortly after that I saw there a game starting with 3840×2160 at 60p. And now I was able to set the desktop to 60Hz, too.
Is it possible that the hotfix release of the gpu driver fixes some problems?
But besides this I am interested in a fw update.
Best regards,
Stephan

That’s unfortunate to hear. We are aware of some compatibility issues mainly with older GPUs (and architectures). Can you share which GPUs are in your systems and model numbers of the 4K TV’s you’ve been trying with? Thanks!

R9 290x, NVIDIA Quadra 4000, Vizio p502ui-b1, Vizio M50-C1

I have no feedback on a Quadro 4000 series but am certain that it runs in a R9 290X
I do however have seen many issues with Vizio TV’s. Did you get any feedback form Vizio already ?

you can get that by sending an email to [email protected]

Okay, got a few insights after playing around with the CAC 1070 adapter.

Setup:
Windows 7
Nvidia drivers v 361.43
2x Nvidia GTX 680
Dell 3007WFP via DVI
Dell 2007WFP via DVI
Samsung UN55JU6500 connected through a Denon AVR-X4100W

New or old firmware made no difference.  Originally I had SLi enabled, which forced me to connect all three monitors to the same graphics card.  Nvidia drivers only allow output through one graphics card when SLi is enabled.  This only offered me 4K@30Hz through the adapter, which was detected as HDMI and not Displayport.  Disabling SLi and then attaching the adapter to the other graphics card enables 4K@60Hz.  It seems like there’s a limitation (at least with my graphics cards) where Displayport output is not enabled unless it is the only display attached or there is a maximum total output bandwidth.

In any case, it seems like a limitation either with Nvidia’s drivers or the graphics cards. Adapter works fine.

Your post gives me hope. I have a 670 but I get garbage coming out of the adapter. Pray tell, have you loaded updated firmware on your adapter?

I discovered the limitations before I loaded the updated firmware.  The firmware makes no difference.

Disconnect all your other monitors if you have them.  Disable SLi if you have that.

I have the exact same problem as unphased. I have a single GTX 670 conected to an LG tv but I get nothing but red or white garbage.

i heard that it sometimes also helps that if you connect 2 screens, to connect the tv thru adapter as second screen, so not as main …

I’ve since bought myself a GTX 980Ti which is a 900 series card which has HDMI 2.0. Works directly with my TV. I can confirm that it works wonderfully and eliminates the need for this product. Which appears to have only been tested on AMD GPU’s anyway!

Besides, I am certainly not interested in adding more input lag either. 

The Sony TV has bricked itself the next day, but that’s a separate issue entirely. (Death to Android!)

what? this adaptor introduces lag? I need to fix my mouse and everything else  from laggin on 30hz

I have the CAC 1070 Rev A0-00 on a GTX 680.  When plugged in, I can’t get a 60hz output.  The Nvidia control panel shows that it is an hdmi output instead of displayport.  I’m guessing the adapter is not using its active mode or doesn’t present that to the GPU.  Where can I get the new firmware to test?From hkscfreak

 
Another casualty here. I just bought a GTX 680 in anticipation that the CAC-1070 will work on it to get me 4k@60Hz. All it gave me is a red blank screen and boot up bleepings. Other output ports works fine, but no 4k@60Hz because those are HDMI 1.4 or DVI ports. I’ll have to sell that graphics card at a loss. 

Hi Catbert and hkscffeak,

It often helps to un-install the graphics driver completely. Especially by using update-feature for drivers, old files remain in the register that could be “in the way”.

Please uninstall the 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/

When done please download and install latest driver for your card yourself here for your card (don’t let Windows or any other auto-installer do that).

I cannot even boot with the adapter. How am I supposed to do anything on the driver side?

Does the GPU work with other monitors? I never had issues of the sort that you are describing.

GTX680 is kepler based Graphics ? Problem sounds like i have heard from other Nvidia Kepler Based Graphics Card user …

Hi Prazal, please try setting the color depth to 8bit and perhaps a firmware update will help you. For that send an email to [email protected]

How can you do that ? As far as I know that was only possible on old versions of OSX, on el capitan or yosemite there is no option, isn’t it ?

Eduardo, I have the LG UF770V 55″ what tv do you have? Also what pc do you have?

I have the same adaptor, macbook pro 15″ late 2013, I have tried with a macbook mid 2015 brand new, it still doesn’t work. …

Firmware update makes no difference

Super! 

thank you very much for the new Firmware – worked like a charm-
the adapter is awesome UHD Deep Color at 60Hz – perfect. 
Really Great – i ve been waiting for this adapter long time.

small note: in the email i received (i also wrote this back in the email) it mentioned 

" most probably you need to set the Ultra HD Color to enabled manually in the setting of the TV for that HDMI2.0 port." -- in fact with this setting turned off the adapter does not need the update to work perfectly. Meaning you can use the adapter at 60Hz in a LG 4K if you do not turn on HDMI UHD Deep Color (i am yet to see the difference between deep color on and off), if however you want to use LG UHD Deep Color then the Firmware update is needed. 

Thank you again for great support and GREAT PRODUCT

Eduardo 

I have the same problem except that i have a Samsung HU 6900 and CAC-1070. can you help ?

Eduardo, how did you apply the Firmware update using a Mac? I need this update too, but I don’t have access to a PC. Also, anybody at Club-3D please reply to my e-mail asking for the update.

Is the firmware ‘update’ a beta/pre release type version?

Nope more likes à whql type 😉

Ok, good to hear.

I have now updated the FW succesfully and will reply if my issue is resolved.

I’m having trouble on the same television, but with Nvidia; occasional hints of success but I can never get it to stick. I’m trying to reduce my emi noise around the cable (currently could well be a problem) and waiting on the firmware update. Had any success?

Still no success, especially at 4:4:4 

Hi Jordan,please the sony’s tv spec,your tv can not reach 4k2k@60Hz,
http://www.sony.com/electronics/televisions/xbr-x830c-series/specifications

qingolden of course it can lol, it can at 4:4:4 as well. It was rated a 10 for pc monitor on rtings.com http://ca.rtings.com/tv/reviews/sony/x830c

I‘m having an issue with this adapter and the x830c as well using a GTX760, however when using just an hdmi cable, I can get 4k @ 60hz, but when I try this adapter only 30hz shows up. Not sure how 60hz shows up when using only an HDMI cable as I don’t recall the 760 having HDMI 2.0 which is why I ordered this adapter, but got the TV before receiving the adapter and seems to work without it, although mouse is a bit laggy at times which I thought was due to bandwidth issue, and thought this adapter would fix. Apparently Not.

I have this same TV 43×830, in addition to the 55×850 and cannot get either one of them to do 60hz with this adapter. Has anyone had any luck? So far my request for the firmware update has gone ignored.

I have the XBR65X850C and an amd r7 260 and no joy at 4k 60 or 1980P 120. Hope there is a fix soon. theis resolutions are the reason I bought this monitor and adapter.

I’m in a similar situation.  I’ve got the following:

Processor: Intel(R) Xeon(R) CPU E3-1225 v3 @ 3.20GHz
Processor Speed: 3193 MHz
Processor Graphics in Use: Intel(R) HD Graphics P4600

This is attached to a Samsung un43ku6300.  I am not even given a 60p option in the Intel configuration screen (attempting to set a custom resolution of even 31p leads to a blank screen).

Any ideas?

Please check for latest Graphics Driver for your HD P4600 Graphics, the CPU should be able to support 4K 60Hz output. Samsung TV UHD Color set to Enable and make cusotme resolution in the Intel Graphics Driver for 3840x2160p 60Hz with timeing standard set to CVT-Reduced Blanking (RB).

I did the firmware update and UHD Color mode now works, however, it’s still not 4:4:4 pixel format. There are no options or settings to change the pixel format in Windows through DisplayPort. The options are available through HDMI only, so I don’t know what to do now.

Hi R0llinlacs, you set the color depth to 8Bit ?

Yes, it’s set to 8bit.

I’ve tried older catalyst drivers, updated TV firmware, tried every HDMI input, PC mode, game mode, UHD Color mode, nothing seems to work. I can only get 4:4:4 pixel format at 30hz.

some users mention that in there setup driver 15.11.1 seems to work well …
http://www.guru3d.com/files-details/amd-catalyst-15-11-1-beta-driver-download.html

or update the bios of the graphics card …

Nope, sorry, I’m done dealing with this piece of xxx, I’m returning it.

Today I turned on my computer to get “mode not supported”. Rebooted, still nothing. Tried HDMI and no signal. Rebooted again and this piece of xxx adapter wiped the EDID from my computer. Gave me 640×480 and “monitor not connected”.

I had to put the xxx xxxx Windows disk in to get signal from HDMI. Now my computer recognizes the monitor again. An entire xxxxx hour wasted out of my day just to get a xxx xxxx simple xxxxxxxx signal to my monitor.

xxxx this adapter and xxxx Club3d. I’m getting my money back and you can keep this problem-causing piece of xxxx.

I advise you to restrain from using such strong language to prevent your message from ending up in the spam filter.
Also it is simply impossible for the Adapter to “wipe the EDID for your computer”. The adapter cannot give executable’s  to the PC, it is only able to pass on information in that direction. 
Really sorry to hear you are having such issues, and our sincere apologies for any inconvenience the product might have caused you. Most certainly not our intention.

BUYER BEWARE

THIS ADAPTER FRIED THE HDMI BOARD ON MY TV

BUYER BEWARE

Hi r0llinlacs,

You are free to your opinion of course, however please keep your remarks realistic.I am quite sure that everyone knows/understands that this adapter is just passing thru and/or converting a video/audio signal and not capable of frying anything, nor is it capable of wiping edid info from your system.
I am truly sorry that you could not get it to work and for any inconvenience that may have caused, which is of course most certainly not our intention.

It didn’t wipe any EDID, it only killed 3 of my 4 HDMI’s. It’s not coincidence after hotplugging the HDMI from the adapter tens of times for a week that 3 of my 4 HDMI’s die. The TV worked perfect for over a year until I used this (already problematic) adapter for only a week. It’s electrical, anything is possible, I know from experience. I’m not mad, I have the extended warranty, but it might be something you’d want to look into.

Don’t get me wrong, we take all issue seriously and will most certainly look at all feedback we receive, so thanks for that.

thanks for the feedback

Hi DeathofChaos, thank you for your feedback. Before concluding that the adapter doesn’t do what it’s advertised to do, please bear in mind that the firmware in this (advanced) adapter needs to establish a handshake between a very wide variety of hardware. Our HDMI 2.0 adapters are the first to ship globally in volume. This is new technology, although it has been extensively tested and we wish it would work perfect in any configuration it doesn’t. But based on the feedback we get it does a great job for most customers, enabling functionality they did not have before.

At this moment many of the support questions we receive are concerning users who try to get 4K60 working on a Vizio TV. The recent firmware update for the adapter did resolve some of the Vizio issues so updating the firmware update is definitely worth a try. It’s also possible there may be other causes for the specific issue you’re having.

Can you provide us with more info about your setup? You use an R9 280X, it most likely has an mDP output. Do you use a CAC-1070 DP to HDMI 2.0 or CAC-1170 mDP to HDMI 2.0 adapter? If you use a CAC-1070, do you have another (mDP to DP) adapter in between? What type of HDMI cable are you using? Which AMD driver version are you using?

This is all relevant information which helps us with trouble shooting and finding a solution for you. Thanks!   

I did end up getting the firmware for the adapter today and it didn’t help. Also, I have an ASUS DirectCU II Top version of the R9 280X, it comes with 2 DVI, 1 HDMI and 1 DP. I’m using a Mediabrige Ultra Cable that’s rated for up to 18GBps speeds and is compatible for up to 240Hz refresh rates. I’d like to also note that I haven’t gotten it to successfully show 60Hz in dxdiag since the time I explained in my earlier comment. I apologize for any rudeness, I’m just extremely aggravated over this because it’s SO close to working yet it just won’t budge where it needs to. Would you happen to have heard of any fixes people have undergone pertaining my specific TV model? The firmware is (from what I gather) the newest one to date and has caused problems even for nVidia cards that have HDMI 2.0 out ports.

Hi DeathOfChaos,

Nope sorry we have not been able to get any feedback from Vizio, nor have i heard of any end-users receiving any help/tips/trick from Vizio. I do know that most Vizio TV’s actually only support 4:2:0 on the “HDMI2.0” port. 
Please try driver version 16.1 (latest) or 15.11, users seem to have most success with those … assuming you have WIN10

I’d like to add that a friend recently let me try out a GTX 970 Ti card that has an HDMI 2.0 connection on it and the HDMI sent out 4K at 60hz with no problem.

thanks for the feedback

Hi Terracode,
Thanks for the feedback.

worth a try, please send an email to [email protected] for that

Hi Jordan,
That cable looks of a good quality, it even states it is an Active Cable which is normally not necessary up to 3 Meters/10Ft. Since the Adapter is also active, perhaps the combination gets “too active” … you have a possibility to try a good quality passive cable ?

I have a feeling that some folks that are having (cable related) issues is due to EMI interference that may be affecting the signal from the adapter to TV.  Since the CA-1070 is an active adapter, there may  be a possibility that EMI interference could be being introduced unless the adapter is filtering as well.  I can say that the cable with Ferrite Choke worked when 3 other cables worked up to a certtain point.   Some systems may not introduce as much interefence as others and also depends on if cables cross power cables from PC or other devices..
Amazon Basics Std cable: 4K/50Hz and 4:2:2 color
Amazon Basics High Speed: 4K/50Hz and 4:4:4 color (unstable)
HDMI cable with good sheiding and Ferrite Choke:  4K/60Hz and 4:4:4 color (stable)

Hello GoodKitty,
Vizio P series Tv is alreay a ‘chanllange”, Nvidia 600 series on itself is also quite a challange and i have not yet come across a 5 meter/20 feet cable without it being active that would actually be bale to output 18gbps, challange nr 3 so to say.
Often the Strange colors mean there is not enough bandwidth available and related to either HDMI Cable and or settings of the source/pc. The last one you can check, by setting the color depth to 8Bit and  Chroma to 4:2:0 or 4:2:2 if the software lets you …

answered the [email protected] email …

NickZimmerman, did you had any luck ? I’m having the same issues …

Haven’t tested it in OS X in a while, but force installing the AMD drives back in March was able to clear it up for Windows at 2160p60.

It’s typical that our support team has not received any message from you detailing your configuration. We are aware that our adapter has compatibility issues with some (mainly Vizio) TV’s but it’s highly unlikely and unprecedented that the adapter would ‘fry the HDMI board’ on your TV.
For direct and personal support please contact us via [email protected]

What else would cause it? I’ll send you the work order for the repair if you don’t believe me.

Also, it’s electrical, anything can happen. So it’s coincidence that after one week of hotplugging the HDMI tens of times, three of four HDMI’s fail? That’s not coincidence, something happened.

Hi Maia,

Assuming you have a Intel i5-4288U CPU in your MBP with HD5100 integrated graphics, i doubt if that will work. According to Intel Specs it cannot output higher resolution on DO output than this: 3200×2000 @ 60Hz
http://ark.intel.com/products/75991/Intel-Core-i5-4288U-Processor-3M-Cache-up-to-3_10-GHz

52Hz is the highest that late 2013 MBP will go. My wife runs one with a Dell P2415Q.

This worked for me!

Hi ZeroGravity,

R9 280 should do just fine, Sharp UE630X should have an HDMI2.0 input suited for PC connection (you might need to en-able “Advanced (color) settings” or something of that extend, for the HDMI port you are using, but should not be a problem. HDMI 2.0 Cable, is a bit tricky because i know that many cables out there claim they can do UHD or 18Gbps, but in fact many of them don’t ! I wold advise you to buy a certifed cable for use with such high resolutions, like our cac-1310
