Windows 10: How to fix flickering RDP connection on 100 Hz display

I have a new 100 Hz monitor, and have set up Windows and my Radeon card to use 100 Hz (with Freesync, if that matters).

I'm connecting via RDP to my work machine, and I see flickering when the RDP window is in fullscreen. I guess the connection is only using 60 Hz (or even less), which leads to synchronisation issues.

Is there any way to make the RDP connection use Freesync, or use the full 100 Hz? Or reduce the refresh rate to 60 Hz when the RDP application is running in foreground?

4k display flickering on HP z24s monitor on 60 Hz with DP1.2

About a year and half ago I bought a new 4k monitor: HP Z24s.
The very first batch.

And there has been a constant disappointment. I decided to not return the display to the shop, because everything else was perfect, i.e.: colors, overall quality, price, etc.

The monitor is connected to Radeon R9 390 8G Sapphire Nitro adapter with 3 meters DisplayPort 1.2 cable.

The problem only appears when I try to set the refresh rate to 60 Hz.

On 30 Hz everything works as expected.

Sometimes, the problem is solved when I set the refresh to 30 Hz, restart
Windows 10 LTSB, and then set the refresh rate back to 60 Hz again.

The cable isn't the problem -- I tested it using another display on 60 Hz and everything worked fine. I also tried the cable using different R9 graphics cards (all from different manufacturers). The problem also persists when using another cable altogether.

I starts when I play a full-screen game, or sometimes at seemingly random times with no obvious cause..

Also, I updated monitor driver, and some time it looked good, but with every second AMD driver update I get this problem off and back.

Does anyone know how to fix this problem, or have a similar experience with this display?

P.S.: On Linux Mint 17..18, everything works like a charm -- no flickering on 60 Hz, both with opensource and proprietary drivers. However, on Mint 18 the are opensource only. And Windows, there is no difference if I set the color depth for HP monitor to 8-bit or 10-bit per color.
So bandwidth is not the issue probably.

 

display 2 flickering?

Hi,



Thank you for writing to Microsoft Community Forums.

1. Since when are you facing this issue?
   
2. Have you recently made any changes on the device?
   
3. What is the make and model of the computer?
   

Here are the few steps you can try to fix the issue.

Method 1



Make sure all connections for the monitor are properly connected.

Check the cable at both the computer and monitor ends. If tightening it down or reconnecting it doesn't fix the problem try replacing the cable and check the status of the issue.

Try connecting on a different monitor and check the status of the issue. If the issue still persists on the other monitor.
