Need some help identifying on screen thing

[hakazuki]

is this image persistence or something else. like dust or something under the screen?

this is an LG 246wp-bn monitor has been perfect till I started noticing this blotch of something on it. at first I thought someone rubbed the screen but I'm the only person to use my pc. And I've never touched the screen, so I'm totally confused about this. Here's 4 pictures I made an arrow pointing the issue area. Only prob is that it's very hard to take a clear picture of this. It doesn't show up on pure white/black/yellow/green/blue screens. it only shows up on grey screens and unsaturated color screens. like muted green/blues/yellows etc.

I read you can make a screensaver into just a pure white color. and leave it running for 20-30 mins a day to help remove the stain/bloch/burn in. I wanna know for sure it's image persistence before I have to waste my time leaving the pc on with a ss active.

You should probably RMA it :-/

My guess is that the backlight diffuser or some other filter somehow started to crumple (probably bad assembly of faulty materials). RMA

I bought this lcd a little less than a year ago (10/18/07) would I still be able to rma it? I assume I'd have to send it to LG not the place (bestbuy) I bought it from.

I'm really not familiar with these procedures in the USA. But I guess you should have at least one year warranty?
