PC Monitor goes blank after a few seconds

So I think I found the fix. HOWER LET ME BE VERY CLEAR, NOBODY SHOULD HAVE TO DO THIS.

Under the compatibility settings for the app I could reliably reproduce it there is an option to use legacy ICC color management.

What this setting actually does I have no idea, but since one monitor is HDR and using it and the other monitor is not. There could be conflict in windows, but whatever.

This isnt something that anyone should have to sleuth to figure out.

Well before yesterday this only happened in DOTA2.

I enabled auto HDR just out of curiosity since the even viewer keeps showing something about brightness and that made the problem so bad that it was crazy.

I use HDR normally on the monitor and Windows, but not the auto feature.

I changed cables. Now I dont know if its windows being stupid or nvidia but if you use HDMI and DP even though HDMI is the first port on the gpu the DP always stays no 1 even though that is the second monitor.

So I switched to both DP and at least now the main monitor is no1.

However since yesterday I noticed when opening photoshop the same black screen thing happened. I opened Topaz video AI and it also happened there a couple of times. Played other games for hours and have no problems. Ran systems stability tests with cinebench and futuremark. No stability problems.

Im using the hotfix driver for Nvidia because of the micro stuttering. 14700k, 32gb ram, 4090. Nothing is overclocked. All my drivers are up to date.

I have a way to replicate the problem with video AI. Is there a way I can upload a video or something?

Hello, fanus van rooyen



Welcome to the Microsoft community.

Hello, I'm sorry to hear about your problem, you seem to be having issues with your monitor being connected externally after running a game.



Before I offer you some advice can I ask you some questions so that we can better advise you on how to proceed:



1. Do you mean that the problem occurs after running a specific game, you can try to do a clean boot to see if opening the game in clean boot mode will also affect your computer. You can refer to the link below: How to perform a clean boot in Windows - Microsoft Support

Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.

These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.



2. What is the game you are referring to, and what information about your computer can you provide?



You can provide feedback on the above information.

Thank you for your time and effort to work on this topic.



Best wishes
