CS2 Displayport handshake issue (?)

[ekkerson]

Hello, recently when I start CS2 theres a 50/50 chance my screen goes black and shows a "no signal detected" after the tabbing in and out spasm CS has at the start, and then my entire PC freezes for 2 minutes, then after responsiveness comes back I can use my pc just fine but my main screen is dead and wont turn back on until restart.

ChatGPT says it could be a "displayport handshake issue" and ive tried many solutions but I figured id ask you guys cause chatgpt is straight slop, please give me any ideas to troubleshoot.
Ive already tried both display and gpu scaling, ive tried resetting all my resolutions in CRU, tried using SRE, reflashed monitor firmware, downgraded monitor firmware 2 versions, disabled DDC/CI, many fresh driver installs, many windows resets, tested the GPU for errors for 30 minutes on OCCT (nothing), reinstalled CS2. I play with MPO OFF and FSE Legacy Flip cause its the most optimal for CS, I dont know if that can cause the issue but I doubt.

Please ask me any questions and let me know what else I can try, and If you know any simillar threads with issues like this since I wasnt able to find any.

I am using the stock DP 1.4 cable that came with the monitor, I have a second monitor thats 60hz and is HDMI.

Monitor: AW2523HF
GPU: 6700XT
Drivers:25.9.1 (happened on 25.9.2, 25.3.1, 25.6.1, 24.12.1)
