My latitude e6430 had a shitty 1368x768 screen, and so i upgraded the screen (and display cable) to 1600*900 yet i see these persistent red pixels that only appear on certain colors. Like if the red columns were shifted to the right. I double checked in the eBay description that the display/cable was A. Compatible with the latitude e6430, and B. functional. Im at my wits end, is there a way to fix this or am i stuck at 1368?
