I just got my first plasma, a Panasonic st30 as suggested on here. I think it looks great but have not messed with the picture yet.


From a quick search i think what im about to describe is called SDE?

When I stand very close to the panel i can see flashes of different color light, even on a black screen, kinda of like a grain. Its on video games and movies so I know its not a signal problem. I looked at some panels in the store and none had as much or large size grains of light as mine.


Also when the set is off but still has power going to it there is a gray color to it, not completely black is this normal?


Any info would be great. Thanks

SDE is screen door effect. Once you get close enough to the panel you can see the pixel structure which resembles a screen used on a door or window. At what point you see SDE depends on the size of the pixels. Pixel size varies depending on the number of pixels and the size of the display. Whatever "flashes" you see are not SDE.

You've got some dancing pixels, which is actually very normal for plasma and happens on many sets, some more than others, you shouldn't be able to see it unless you're right next to the screen.


The reason the screen doesn't get completely black has to do with the minimum luminance level of the plasma panel. That's as deep a black as it will get, sometimes it looks very black, and sometimes with darker content, it can get a little gray.
