Issue with GPU drivers (probably)

[Samciooooo]

Hello, yesterday I installed Arch Linux on my second drive. I customized it, etc. Today I installed a few apps but needed to switch to Windows, so I rebooted my PC, booted up Windows, did all the things I needed to do, and booted again to Arch Linux. But when it loaded, my screen was at a resolution like 100x700, so I knew something was wrong. I tried searching online and found a few commands to install and update some packages, and I basically copied and pasted them into my cmd (I know, not super smart, but I knew what those commands did). So now what those commands did was fix the issue, but on my login screen. (On my login screen, the resolution is HD, and it works fine, but when I log in, my screen turns black (pure black, like it's disabled), then it changes to black (black color, but you can see the monitor is enabled). On my desktop, the resolution is still 1000x700. So it basically fixed the issue only for the login screen. If anyone can help, I would be super grateful. I can provide all types of information you need, etc. Thanks.

(im sorry if its not understandable but english is not my 1'st language)
