Thanks very much for taking the time to post those pics Sallermas, and they confirm that the new revision has pretty much solved the input lag problem the 2408 was plagued with (near enough halved the lag I think? Down from ~60 to ~30). I think I can safely go ahead and order mine soon!
With regards to other tests, my technical knowledge of monitors does not extend far enough to suggest any (except maybe a picture of the monitor with a black screen to highlight any backlight bleed?) but I'm sure other users will be able to do so.
