After checking out a potential buy, the Panasonic P50U50, in store, I thought it looked great, at least whenever there was a good amount of darkness on the screen. When the screen got lighter in color, the image took a DRAMATIC brightness hit. One moment, the colors would really seem to pop, while the next moment the image would be about half as bright.
I've since read that a lot (if not all?) of the latest plasmas do this. Is there a setting to disable this feature? I'm not a fan of auto-dimming at all. The Samsung EH5000 LCD series had things the opposite way - whenever the screen was displaying a darker image, the backlight would dim to reach those deeper blacks.
If this sort of auto-dimming would drive me nuts, should I avoid plasmas altogether? I often play games, from retro to current PC games. A lot of those retro games are very bright and colorful, and I'd go crazy if the screen gets dark every time I want to play something like Super Mario Bros. or Mega Man.
