I recently upgraded from an older CFL-lit LCD to the LG 55LW5700 (LED edge lit). Once I calibrated it, the picture looks amazing in bright scenes. However, in any extra dark scene, or if I plug in my PC and project an all-black screen, it's clear that the black level is not consistent. If I'm facing the tv head on (or at any angle really), it's clear the upper left corner is brighter than the rest (about a 4 by 6 inch triangle area). The far right side's edge is also a bit lighter black than the rest of the screen. I only notice it in dark scenes though, so it's not severe (and still better than my past CFL LCD).
Is this kind of black consistency expected in LED LCDs? Or should I think about trying out another one to see if it's just this set? Thanks!
