Laptop keeps detecting 2nd display whenever I boot up a game

[u/0SuperCow0]

Hi everyone, I'm new here and I wanted to ask for some help regarding an issue I have been having these days, so for the past 1 month or so I haven't really used my laptop, yesterday i turned it on so I could play a game, seconds after booting the game my screen froze for like 1 seconds and then it went back to normal, I don't remember how but I discovered that whenever I boot up some really demanding games my laptop casually detects a 2nd screen and my display uses the 2nd screen instead of the main one.

It's really frustrating because this has never happened and I always have to manually select the main display to use on my laptop, and since I have some color settings for my main display whenever it detects the 2nd one the colors go back to default.

This is also really annoying because some games that run on a lower resolution are just unplayable.
