Dell XPS 9360 display showing some weird glitches (maybe IGPU related?)

Hey guys, first time in a while chatting here. Heres the thing, I bought a used laptop (Dell XPS 9360) and the screen has these weird lines on the bottom. Thing is, the screen still displays the windows task bar when I restart the computer which makes me thing this is an iGPU issue and not a display issue. I have checked the display flex cable and everything is okay. Has anybody ever had this happened to them?
Any suggestions on what to do? I dont really want to waste 200 euros on a screen just to find out its the iGPU.

Have you tried an external monitor?

This could be anything, frankly.

>flex cable broken somewhere it's not observable/hidden

>display clocked incorrectly

>display defect

>gpu defect

 

You can for the least connect an external display and see whether it does the same or not. If it does, it most likely is a gpu defect.

A display through a Thunderbolt 3 dock does NOT present any graphical glitches so it lead me to believe its the display but Im still skeptical. Is there any sort of display tester/controller I can buy to make sure the display is okay or not before I order a new one?
