I recently got a 63B590 and the picture is definitely great for video, etc. But being new to the Plasma world (my last set was a DLP) i'm trying to understand a few things that I have noticed with this set.
1. When I started to use some of the break-in images on this set, i noticed that on full-white and some mid intensity shades of green and blue there were "seams" across the screen. It's hard to describe these visually as they are very "faint" but go all the way across the screen, perfectly level and do not move. Visually they seem to be flat on top and are only about 1/4" high and are an ever so slight shade difference in the color being displayed. I first noticed it as a "band" about 3" tall that was about 5" down from the top of the screen. The band appears ever so slightly lighter in shade than the rest of the screen. You can notice add'l lines that are even fainter in about 5" increments down the screen, again horizontal across the entire screen. These are noticeable even at 10-12' back, in fact is easier to notice standing back than up really close. You need a dark room and a minute or so for your eyes to adjust.
After first noticing this i changed inputs, relocated wireless equipment, subwoofer, etc. and then finally went to the burn-in protection menu and found it in the scrolling grayscale as well with nothing else attached to the plasma. Again it's very subtle, but noticeable and I then could see it in some video content that had a mid tone color that was constant, or at least covered the top portion of the screen, like a blue sky. Also commercials that have a lot of white in the bkgrnd, etc.
It is definitely not burn-in or IR so I ruled that out. Just wondering if A) This is normal for a set of this size/type and/or B) if anyone else can see this. Usually easiest to notice looking at a full-white screen in "dynamic" mode to drive the panel brightly, but noticeable at lower intensities too.
2. Also I have noticed some, what i'd call streaking, where you see a "streak" extending to the right from solid text on a solid background. For Example, the "preview" screen that comes up before movie trailers that is all green with bright white text. I usually see some from that as well as other commercials that have a lot of solid areas.
3. Full-bright - I know that Plasmas are not as good at driving a full white screen to the entire panel(vs LCDs), due to driving all the cells at once and there being some power limiter on the panel. When i pull up a full-white (say break-in image again) I see more of a light gray image. If you pull up the input menu that overlays about 2/3 the screen then the remaining white portion tends to "pop" white a bit more, then goes back to the greyish cast when the menu is removed. Just checking to see if that's normal for folks?
Otherwise when watching video content the picture is really amazing, even being safe and keeping cell and contrast setting conservative it looks great. I know I can be picky but want to make sure that i'm not asking for too much here.
I've read others say that they are having problems with the CinemaSmooth option, but I haven't seen any problems myself. But like others i'm not sure how to see the difference. I definitely notice that my BRP needs to be in 24hz mode in order to choose it. So i assume it's working but i'm not sure what content would show the "judder" of 3:2. people say scrolling credits? maybe i can look at that. I'm using a LG BD370 player.
