DP to 4K @ 60Hz HDMI Adapter – Issue Noted

Hi,

Recently, my adapter (DP to 4K @ 60Hz – 4096 x 2160) is no longer working, it is now working with 4K (3840 x 2160 @ 30 Hz only).

I am not sure what has caused this, as I am running Windows 10 Enterprise x64, along with my graphics card: NVIDIA QUADRO K4000, Driver Version: 21.21.13.7295 (Date: 2016-09-22, Driver Provider: NVIDIA)

My 4K TV is the Samsung UN60JS7000 (HDMI UHD Colour Option is ENABLED & has the latest software / firmware / updates), and I am using HDMI 2.0 Cable as well.

Now the situation is even worse: in order to get 4K @ 3840 x 2160 @ 30 Hz, HDMI UHD Colour Option needs to be disabled, otherwise, I either get a flashing white colour screen – when attempting either 4096 X 2160 @ 60 Hz or 3840 X 2160 @ 60 Hz)

I tried uninstalling the device drivers, running ccleaner (clean out registry keys), etc. to no resolution.

At one point, I didn’t get any displays on the TV, and had to resort to using DP to HDMI (direct cable connection from the video card to the TV) and go back to 1920 x 1080 @ 60 Hz.

I was reading the form, and advised there could be a firmware upgrade for my adapter: firmware v.7.26, as per sticker on the cable itself. Perhaps someone can show me if there is an updated firmware?

Can someone please provide additional assistance / further troubleshooting?

Thanks in advance.

I have similar issue.  Restarting the pc loads screen resolutions at random….sometimes!
Sometimes waking the pc from sleep changes resolution also.
Once in awhile a small note appears on win7 desktop regarding a Tablet is not recognized.
I assume the issue is pc related, because most of the time all works fine.
The only way to restore the resolution upon waking is NOT to restart, as that results same incorrect screen resolution.
Rather the solution is to physically pull the club3D plug from the graphics card, then reinsert….the screen resolution resets back to its proper ratio.

Man, I’m so glad that (sorry 😉 ) others also experience this behaviour… I have Skylake -based NUC with an Iris Graphics 540, and the only limitation of it was the lack of HDMI 2.0 support for [email protected] Therefore I thought Club3D’s miniDP 1.2 to HDMi 2.0 active adapter would be the holy grail.
I use this NUC not only as an HTPC but also as my gateway to my NAS. – so I turn it on remotely very frequently.
And from this stem tthe problems I think. If I turn on the NUC after it was turned off last time while being connected to my active TV, no problem. But, if the last shutdown was after a remote session (e.g. TV wasn’t turned on), upon next boot I am always greeted by a black screen. I have to unplug and re-plug the adapter to get picture, and from time to time I have to re-set the refresh rate to 60p  from 30p. As if the adapter fails to “tell” the GPU to push dp 1.2 4k 60p picture… :/ Edit: same situation after waking from S3 sleep.

For setups with TV’s it normally works best to use Custome Resolution with Timing Standard set to CVT-Reduced Blanking, you all using that CVT-RB ?
@ Karthigan, did you try to load a restore point from before this issue started ?
Most probably an driver or windows updated caused it …

I updated the Nvidia driver through their website.  Windows auto update installs a different driver, which I assume is part of the problem.

Also I created a custom resolution Progressive, but noticed that Reduced Blanking was already selected, so this may not be part of the problem.

If I do not reply here in a month, the problem is solved.

Same issue.. Seems pc win7 related, but unplug/plug at vcard resets quickly.

Maybe compatibility problem between win7 screen resolution and similar nvidia control panel settings?

it sounds like somehow the system/driver does not allow a refresh of the connection … really odd because you would think if anything a restart would do just that.

I tried reinstalling nvidia, but same issue.  The components are dell workstation, latest samsung tv, win7, etc.  The clue is the small white bubble windows message – upon a random wake – recognizing a phantom Tablet connection, which alters resolution without input.. In other words, the system thinks incorrectly that a new display has been connected..

I assume the issue has nothing to do with the club3d connector.. I will test without it.
