I can see keeping the USB card w/slides plugged in so you can use the lighter shade slides to look for imprinted IR but running them to clear up IR is a waste of time imo and DNice pretty much states as much in his initial slides post. I feel you need actual pixel movement in order to clear up IR, as in the sweeping motion that the black to white Screen Wpe accomplishes. There is no pixel movement in the slides, just a uniform change of the whole screen pixels which may be good for uniform pixel break-in but for removing embedded images, not so much. That's the way I see it anywho, I could be way off base, just my opinion.
Hmm you are probably right. Although I had a bit of IR from the xbox logo in the top right of the screen and the slides got ride of it. I assume you are correct regarding any form of stubborn IR
