My Acer nitro 5 (n20c1) screen is very laggy and slow in most of it, but there is a bar at the top that is running smooth and showing what is actually happening. Sometimes the laggy part doesn't show anything at all. Because of this I tried connecting it to my tv through HDMI and that worked, the TV was showing it smoothly, but I went through settings and I changed my screens refresh rate to 60 instead of the normal 144hz. This fixed it for a moment, the screen on my computer was working, but as soon as I unplugged the HDMI cord it stopped working. My friend suggested going back to windows 10, but when i did this it made a full reset causing me to have to go through the setup process. But the problem is I can't see anything on my screen except for that small bar, and my tv can connect until the setup is finished. Does anybody know how to solve this?

The clear bar is the blue and grey part at the top that is the only thing I can really see, the rest is either just not there, or super slow
