Hi DonLKSAB,

Sorry but we do not have a reversed MST HUB.

I am not sure what you mean by “i have a monitor that connects 1 dp cable into 2 panels”
I mean i know of screens that are 4K and need 2 separate signal inputs, 1 for the left side and one for the right side of the screen. But that would be the oposite …

[MST1407]

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 ?

Sounds like a Dell Screen issue to me …

 

Dell Monitors sometimes need to have MST Feature enabled manually …

Please refer to your Dell monitor’s owner manual for instruction for enabling DisplayPort 1.2 Multi-Stream Transport (MST) capabilities on your Dell monitor.

By default the Dell monitors are not enabled with this feature.

In the monitor’s on screen menu (OSD), navigate to “Other Settings”

Change the setting for “DisplayPort 1.2” to Enable

Confirm the selection

You may need to reconnect the DisplayPort cable after making this change.

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.

Good day avi1587,

Normally setups like yours work best by making a custom resolution in the Crimson fdriver for 3840×2160 at 60Hz and Timing Standard set to CVT-Reduced Blanking.

We have heard of some issue with the latest AMD Driver Updates, so if the above does not fix it, please do this:

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 driver 16.8.3 yourself (don’t let Windows or any other auto-installer do that): 
http://support.amd.com/en-us/download/desktop/previous/detail?os=Windows%2010%20-%2064&rev=16.8.3

Here is our latest checklist for your reference:[img]http://insights.club-3d.com/wp-content/uploads/2016/10/Checklist-CAC-1070-CAC-1170-180816-1.jpg[/img]

thanks for the feedback

[MST1407]

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

Good day nbgh007,
We have tested the SP2, 3 and 4 with the CAC-1170 and that worked just fine.
We did need to manually make a custom resolution in the Intel Graphics Control Center for 3840×2160 at 60Hz with timing Standard set to CVT-Reduced Blanking (RB) when using a TV (for monitors that can be left at automatic). Then you can select this resoltuion from the Basic settings where it then shows. 
Unfortunately Signal converters in general tend to be very sensitive in with regards to combining them with Hubs/Switches or any other signal converters. This is also the case with the CAC-1170 / CAC-1070.
We did escalate firmware update info of the SP Docks to R&D and factory, but so far no feedback/solution (yet).

[MST1407]

Still sounds like a driver/software issue …

is there a recent version of Microsoft.Net Frameworks installed on the systems?
Programmers often make software by combining their own source code with that of MS.NET Framework. 
https://www.microsoft.com/net/download

Did you have this issue from the beginning or did the problem start after some time ?
Reently update windows or anything like that ?

Sorry we do not have a HDMI2.0 to DP1.2 Adapter (yet).
There is no Chipset available yet for HDMI2.0 conversion to DP 🙁
We will start with HDMI1.4 to DP, so 3480×2160 30Hz max, that shold become available end this year. For the HDMI2.0 to DP solution that will not be any earlier then Q2 next year is my estimation.

This is the support Table for the Adapter … so if your screen supports 4:4:4 at 3840x2160p at 60Hz then the driver software will most probably automatically switch to 8bit BPC

Hi Carbert,

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

[MST1407]

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.

Hi Jan Willem,

Since i also do not know where the problems comes from, i cannot garantee this will work, but i do know it solves many Graphics Instability related isuses.
Worth a try i thought.
