XPS L702x Screen colour change issue (screen shots included)

Sorry for the bad post name as I'm not entirely sure what to call this.

I have been having an issue with my XPS L702x for a while after I dropped it onto the floor. The issue I have is that is mainly that the screen seems to display black (and colours close to it) green and the white as red. This is fairly inconvenient but also seems to be slowing my pc down quite a bit, for a while I assumed it was the screen that had broken and a ribbon cable or something had either come loose or broken, however after taking the pc apart and having a look at the wires they all seem fine. My second assumption is it's something to do with the GPU and maybe that's what's broken (this would make sense as to why the PC is slowing down). I'm wondering if there's a way to fix it as I don't want to buy a new laptop.

I have some pictures here to show what the issue is.

I have tried installing the Dell Diagnostics System Detect Software, but the Diagnostics test cant seem to find the software on my PC and keeps coming up with the error that I need the latest version installed.

What is the latest version of windows on the system? Windows 10, 8 or 7 ? Linux ?

Please run Dell LCD BIST Test by following the steps in link below:

Lastly,

I also suggest you run diagnostic tool (F12 key) to check the rest of the hardware on the system. Please follow steps below.

1. Power off the system. Remove all peripherals (except AC adapter) from system

2. Power on system, quickly start tapping the F12 key continuously until you see Preparing one time boot menu in the top right corner of the screen. In the boot menu, stroll down to Diagnostic and then click on it. After quick tests, click on Hard drive and then Thorough Test Mode. Run Memory, Video Card as well. Report back any error code.
