AnyDesk Sessions - Overly Dark Remote Sessions

[JUGGStheOG]

Starting with driver version 32.0.101.6449 the remote desktop sessions with AnyDesk are overly dark.

PC providing the remote AnyDesk session has the following hardware:

CPU: Ryzen 5 5600X

Motherboard: ASRock B550 Taichi

GPU: Intel Arc A750

Currently installed driver version: 32.0.101.6458

I have done some troubleshooting and nothing I can change resolves the issue. Others have suggested GPU driver being the culprit.

AnyDesk sessions to machines with out an Intel Arc GPU are fine.

Please advise.

Hi JUGGStheOG,

Thank you for the update. Please remember to update your workstation's graphics driver as well. If possible, use Display Driver Uninstaller (DDU) when updating your Nvidia driver. Let me know which driver version you choose for your Nvidia card and the results after the update.

Best regards,

Hello Dhanniel - as a reminder this dark remote session on the DP connection exists on all machines tested. Only thing that the issue has in common on all tested PCs is the DP output on the Arc A750 dGPU.

Thanks.

Hello again Dhanniel,

My workstation's AnyDesk display settings.

Left AVR on and can confirm the HDMI output is not dark like the DP output is.

A750 PC taken locally.

Remote session on workstation. DP output.

Remote session on workstation. HDMI output.

Home monitor (DP) is 1920x1200.

Home AVR (HDMI) is 3840x2160.

Workstation monitor (DP) is 2560x1440.

Hope this helps.

Let me know what you want me to try next.

Hi JUGGStheOG,

I have a few clarifications due to the multiple devices mentioned earlier. When using a DP cable to remotely access your home PC, do all devices produce the same dark output? You mentioned that your work laptop also results in a dark display. Is your work laptop connected to an external monitor via DP?

Additionally, the third image appears similar to the first. Could you confirm whether using an HDMI cable on other devices results in a similar display output? Also, could you let me know what is the model monitor you are using at your workstation?

There might be limitations with the display adapter and monitor you're using, which could be causing the dark display when remotely accessing your home PC. This issue might also be related to contrast and brightness settings. I apologize for the numerous follow-up questions, but as the investigation progresses, various factors need to be considered. For now, let's focus on the dynamic between your workstation and home PC to narrow down the best possible solution. Since you're using an Nvidia GPU on your workstation, could you try disabling the integrated GPU to see if the issue persists?

Morning Dhanniel,

Sorry for the added confusion. I will try to clear things up.

Regardless of what PC I use to remotely access my home PC, via AnyDesk, the DP output (primary monitor) is dark. I have now tested seven different PCs all with differing hardware. They all produce this dark remote output from the DP port. As recently discovered the HDMI output from my home PC is not dark. I am not sure if this changed with an update or if I erroneously thought it was dark when I reported it so a while back.

For clarification on the three images of the Puscifer concert photos.

• Photo 1 with title "A750 PC taken locally" is what I see when sitting at my home PC on the DP connected monitor. Output is normal.
• Photo 2 with the title "Remote session on workstation. DP output." is what I see on all tested PCs when accessing this home PC remotely on the DP output.
• Photo 3 with the title "Remote session on workstation. HDMI output." is what I see on all tested PCs when accessing this home PC remotely on the HDMI output.

In summary before I updated from a previous GPU driver version, version unknown, the remote output from the DP port was normal. I did this update early January. Since then the remote sessions from the DP port has been dark. No matter which PC hardware I remotely access my home PC with the DP output is dark. 

Let me know if I remain clear as mud.

Hello JUGGStheOG,

Thank you for clarifying this for me. I will conduct a further investigation into the situation and provide you with an update as soon as possible.

Hello JUGGStheOG,

I attempted to replicate the issue you're experiencing using the information and settings you provided. After conducting the replication, I did not encounter the same problem. I tested both HDMI and DP connections with the A750. Therefore, I recommend trying a different monitor on both your home PC and workstation. This will help rule out any compatibility issues between your current monitor, AnyDesk, and the ARC GPU.

If the issue persists even with a different monitor, it may indicate that the GPU needs to be replaced, as the problem did not occur during my testing. Could you also let me know the manufacturer of your GPU (e.g., Intel, Sparkle, Asrock, MSI, etc.)?

Best regards,

Hello Dhanniel,

MFG of the A750 is Intel.

Regarding trying different monitors. There is no issue on every other tested PC. Only this A750 remote DP output is dark. Local DP output is fine. Three different versions of AnyDesk have been tested as well. 

Have since upgraded to .6651 (no change) followed by .6653 (no change).

The issue really is odd. I will see if I can find the time to do a clean Win11 install and see if that helps to resolve the issue.

Please don't spend any additional time on this.

Thank you for your time on this issue.

Hi JUGGStheOG,

I'm curious if you've attempted a fresh installation of Windows 11 on your system. Please let me know the results after completing it.

Hello - I don't foresee having the time for a full system reformat for a number of weeks yet.
