I would say that it was for around 7 hours maybe longer, but the game was played for many different sittings for long times. I have since turned the HUD off completely, but I mean it just seems like its stubborn IR. I have not noticed it during normal content except for maybe during a very white commercial. Other then that I have not noticed really unless I really look for it. I really have only SEEN IT when I run the screen wipe or if I pull of the break in slides. Worse case if it doesn't go away I will exchange it at magnolia. I just was curious about this because I have played games excessively on my previous plasma and after a screen swipe it was gone. It has been a couple days since I noticed this IR and it has gotten a little better.
