Hi,
Would really appreciate an idea on this, i'm completely lost.

I cracked the display on my Asus N56VM, and then bought a FHD screen for the exact same model from ebay. The previous screen was HD.
After installing the screen, I immediately noticed booting up that the black background is a much lighter black, more grey, and that the resolution was borked.
Windows recognises it as Generic PnP monitor, with a max res of 1920x1080, but sticking it that high makes everything unreadable, with text having wavy vertical lines through it - cleartype makes no difference - and it gives me a massive headache trying to use it.

Lastly, the screen flashes blue/red/white sometimes, and seems to be throwing a fit at most moments.

I've tried: double-checking in Ubuntu, updating drivers (nvidia 630m and Intel 4000), changing resolution no end, re-seating the 40pin connector, cleartype, adjusting brightness/contrast.

Vendor says it's an issue with resolution - even though my model usually comes with FHD and the Graphics card is 630m which is enough, sounds like a palm-off excuse, any ideas?

Thanks if anyone actually went all the way through to read this ;)

Jimbo,
I have exactly the same issue and have tried all the same things, did you ever manage to solve this? I suspect it might be a slightly mismatched LCD but I sincerely hope not.
