Few days back, I got issue in my Acer Predator Helios 300 (2020) due to which I needed to replace my screen. I got to an official Acer service center to get it replaced along with I asked them for thermal pasting as well.
After the screen got replaced, I'm unable to see any option to switch between 60 hz to 144 hz.
You can see there is no option to select 144 hz
And also when I play games, my Nvidia GPU Activity says : "There are no displays connected to this GPU"
I doubt that the engineer might have done some mistakes while connecting the screen or are there some software issues? Please help me. Due to this reason, I'm unable to enjoy 144Hz gaming and when I play games, its stuck on 60 hz and there are visible glitch effects on the screen while playing games. None of these issues existed before the replacement of screen.
