Windows monochrome failure

[CV453]

Hi, im pretty inexperienced with computers but have tried both the standard windows install and the manual process after following a youtube tutorial. USB debugging is enabled and have tried both methods in charging and file transfer mode. This is the output i get from the windows install process:
