So I guess i'll start by noting that I never really considered myself a videophile but i am aware and often able to see alot of the issues that videophiles like to be picky about. I thought I would post my thoughts and issues on this set.
Probably the first issue you'll come across with this set is glare. Yes there is alot of it but as others have noted it's quite simmilar to the glare you would see on a lot of older crts, so if that never bothered you before it probably wont now. Honestly it's not something that bugs me that much and is on the lower end of my pet peeves, but the lighting is fairly easy to control in the room it's in.
Picture- Overall I'd say the picture is pretty decent, I've no way to test the black levels but they seem decent although they don't come anywhere near to meeting the blackness of the bezel. Color seems ok.
Lag- while i only did some preliminary tests with a laptop quite some time ago the lag did test rather high. Between 80-100, that was through the computer connection which was the only one i was able to test and was done rather hastily so when i get a chance i can try to redo those with some greater accuracy.
Line Bleed- Yes this set suffers from line bleed although I can't testify as to how bad or good it is compared to other sets. I can only say that I've noticed on a few occassions to varying degrees. If aynone has suggestions on how to qualify this with specific source material or tests I'd be able to look at it to give a better opinion on it.
Floating blacks/changing contrast- I have noticed on occasion the brightness of the screen adjusting itself regardless of whether or not the energy saving features are off. I haven't noticed the floating blacks (although i've not really been looking) like some panasonics were displaying last year and it's my understanding that what i've noticed may just be the abl or whatever it's called which all plasma's are coming out with for energy consumption purposes and may just be undefeatable. Still this IS my biggest pet peeve so i do notice it whenever it happens.
My biggest complaint, and warning to those looking at the tv, is that I appear to have some vertical banding issues. I have two noticable vertical sections that are darker than the center portion of the screen, most readily seen when there's a solid color on screen. I'm actually quite upset by this as I missed my opportnity to return to it to the store and lg is refusing to honor the warranty saying that it's a burn in issue. Now this is my first plasma but I'm well aware of the dangers of burn in and have done nothing which might have caused the problem im dealing with and their customer service is atrocious. For that reason alone i would recommend you stay away from this tv and all LG products for that matter.
