Trouble with 144Hz-Black screen.

[1eyePEEKS ♣]

Hey guys, so I just got back to CS2 after a 4 year break and I think there is something wrong with my screen.
While my screen can supposedly support 144Hz gameplay, when I set it as preference inside CS2, something weird starts to happen: screen goes black during the game,sound stops and after 5 seconds, it all comes back and I continue normally. This happens more or less 8 times in a competitive session, so you can understand what can go wrong with that. I have tried putting -autoconfig in launch options, nothing changed, I have already changed the resolution to 4:3 and nothing changed, G-sync is already disabled, I played with V-sync on/off and nothing changed. Other games, like Albion Online, Marvel Rivals and Mount and Blade are not giving me this issue.
I'm sure some one of you has had this happening to them before, so, before I buy a new screen, I would like to know if there is a fix.
Thank you in advance.
