This was my initial concern as well, and I totally had the same feeling you do. I wasn't sure if this was going to get worse, or if it was going to jump out at me more on certain games, but after understanding this a little more I would say don't worry at all. This is just something that happens normally with this kind of panel. The fact is like I said above, I would never notice this "issue" on my own, enjoy your monitor, i'm keeping mine, the performance is still really "game changing" as I stated in an earlier post - it is a really nice piece of hardware
edit. I'd also like to add that i've done my fair share of snooping around forums, and been elbows deep in countless pc's, played with tons of hardware, been an early adopter/guinea pig of new tech, been putting these pcs together and tinkering since I was a wee one. . . I say all of this to qualify (albeit poorly) the following statement.
There is no such thing as a perfect product, ALL hardware has its drawbacks.
I might love a pair of headphones because when I pop on the Beatles and close my eyes I feel like I am standing on a rooftop on Sevile row in London, and the same pair might be eviscerated on some forum for having a sub-par "soundstage" when watching a bluray.
This is of course an extremely personal decision, wether or not the performance outweighs the drawbacks on a piece of hardware - in my opinion, which could change over the coming months this particular display is worth enjoying.
Good thing is, Dell is giving us three years to decide, which by then all bets are off in terms of what tech will be out there, but I think this is a solid purchase.
