Master PC #1: Fix screen flicker and no signal when starting up or turning on — in under 1 minute.

Описание: One day, I ran into an issue — my monitor would occasionally flicker annoyingly while gaming. Every time I started up or restarted my PC, the screen wouldn’t receive any signal, and sometimes the refresh rate would drop to just 120Hz. Turning the monitor off and on several times would bring the display back, but that was only a temporary fix.

After trying countless solutions found online with no success, I began to suspect my DisplayPort cable was the culprit — but it wasn’t.

Here’s the method I used to completely eliminate this frustrating problem. Hopefully, it will help you too if you ever run into a similar situation.
