M17x R3 "Blue Static" on LCD screen

[MJ6]

Hey guys. I've been a lurker on this forum for quite some time, and all the info I've found on the forums has been more than helpful and insightful, but it's time to reach out to you guys for some help and trouble shooting.

I have an M17x R3 that I purchased back in early 2012 right before I PCS'd to Guam. Loved it. Fast forward about 6months and I noticed the laptop screen looked like it had what can only be described as "blue static" on it. I attempted to update my drivers for the video card (Nvidia 580m), but nothing changed. Of note, while the laptop screen would get this issue, when I would connect my laptop to my TV via HDMI, the TV screen looked perfect.

Eventually I ended up calling Dell customer support (which is obviously a misnomer) and convinced the rep to send me out a replacement screen as I had no technicians in my area and wasn't going to risk sending it to them overseas. Fast forward: I received the screen, installed it, booted it up, and it was even worse that the original screen. Called again, got another screen sent. It's worth mentioning that Dell refuses to send new replacement parts and opts to send "refurbished" items that lack any semblance of quality control.

This went on for about three months and six different screens, each one with either the same problem or another problem with the screen itself. At this point, I pretty much said screw it since I have it hooked up to my TV the majority of the time.

About 4 months ago I came across this site and decided to upgrade my GPU to the Nvidia 780M. I followed the directions here and got it up and running. Now in the back of my head, I was hoping that maybe the previous "blue static" issue was a faulty GPU thing, but even with the new card the laptop screen gets it.

At this point, I'm at the end of my rope. Dell is obviously no help as my warranty is up (not like they helped previously anyways) and I'm just lost as to what the issue could be. My only other option I can think of is that maybe it could be a motherboard issue, which confuses me as the HDMI function works flawlessly.

So, cliffnote version:
