I recently picked up a new 51" and am starting to notice some pretty bad IR. It doesn't last for long so far, but it's quick onset. I have probably just under 100 hours so far, and I have the brightness and contrast turned reasonbly down from the default settings.
Basically it does not take very long for a high contrast image to leave some IR. It goes away fairly quickly so far, but then again I'm trying to be very careful with it. An example of what I'm seeing is a recent Volkswagon commercial that displays black text and the VW logo on a white background for about 5-7 seconds at the end of the ad. When the next ad comes on, the text and VW logo are clearly visible for around 5-10 seconds at it fades away.
After noticing this, I've started seeing similar occurrances during regular programming as some scenes that linger in the same spot for serveral seconds shift to lighter background images.
I haven't noticed much talk about IR concerning this model, so I'm not sure if what I'm seeing is normal. I'm coming from a 9G Kuro, which never experienced any IR whatsoever. I suppose my main concern is that if this IR is happening so quickly, what will it be like if I start to watch something like a baseball game with more static images for longer durations of time? I'd also like to eventually game on this set after it has some more hours on it.
Can anyone shed some light on whether this is normal, and if it will get better over time?
