Image retention is still an issue, at least with my Panasonic. I have had the panel replaced once because of it. I purchased the Disney "WOW" Blu ray and use the pixel flipper frequently. For me the worst retention comes from the History channel (what I watch the most I know) and one of the local news channels. Both have a big yellow marker. Why do we need these damn things? I know what channel I am watching and don't need a reminder after I shut the monitor off.
