Resolution bug

[Hypa]

So i was messing around with gigabytes software for my gpu to see if i could get my gpu's annoying flashing rgb to stay on one colour. I somehow managed to accidentally change the resolution of my PC in the app and now every time i restart it goes from 2560x1440 to 800 by 600 or some other smaller resolution and for the life of me i cant find the setting in either aorus engine or gigabytes "xtreme gaming" engine(im assuming its this one as every time i open the app my resolution changes). i don't know how but even if i uninstall them the setting still remains and still changes my resolution on restarting my PC. Worst part is i couldnt even change the rgb presumably because on my non gigabyte motherboard..... any help would be really appreciated

Can you just go to display settings in windows and change the resolution?

Yeah i can but doing this repeatedly on startup can get rather irritating id rather fix than tolerate.
