More power to you if you think it's not a big deal, but I disagree. The backlight bleed on both of the LG monitors I had was clearly visible when the monitors were in normal, everyday use -- not just on full black test screens. Contrast distinctly washed out and colors shifted severely in the regions of the screen where the bleed was present. Some degree of backlight bleed is of course normal for this technology, but the LG's I had were unacceptable, especially at thier $1300 price point.
I guess it's a matter of "degree" in some cases. For example, the 34UM95 I own has very minimal light bleed in each lower corner, with just a super tiny bit in the top corners. But in none of the corners is the light visible at anything but the darkest of scenes. Let me try to post a pic and I will show you what I mean. <back to the BatCave!>
