Gaming laptop got worse after changing screen

I recently changed my gaming laptop screen after it blacked out, but ever since then, my "fixed" laptop has been lagging so much and the FPS has been dropped to 20~30 from a consistent 90 FPS in the past.

I tried updating my computer drivers and swapped the GPU to NVDA instead of the default laptop GPU, but the problems still persist and I suspect it is because of the new screen.

I don't know how to fix it (ie: do I need to replace the screen again?), and I need some help, thanks!
