RE: Dell Inspiron 15r 7520 SE screen model number
Yes I did replace my Screen with a FHD display and it is working great. The only problem you may have is in trying to find the correct cable to link the motherboard to the display. I had to purchase one via ebay from america. there is a video on utube showing you exactly what to do - it's great help
The cable required is R4WW7 i got it from a seller called part4sale06 paid approx $44 which included postage and import charges.
I've upgrade my keyboard to being backlit as well. I have an i5 processor like the idead of getting a i7 but not to sure about my skills in upgrading that and bios ....
