On my Sharp 32D43U the color gradient is messed up sometimes. I don't really no how to describe it but when a color is gradually transitioning to a darker or lighter shade instead of being one smooth transition it looks like different bands of color next to each other each one lighter or darker than the last. I usually notice it on the 360 startup graphic and the MS Game Studios graphic, not really a big deal there but I can see it sometimes in games too, like when looking at the sky, and it's really apparent in SD games I've played on it like FFXII and Super Mario Galaxy but I assume that's just an aftereffect of the scaling. I should have Casino Royale on Blu-Ray this weekend so I can test if I see it in movies, at which point I'll be really wigged out.


Any ideas? Is this common on these TVs?

This is a result of there not being enough colors to display the gradient properly. This can either come from the source not having enough colors in it, or the display not being able to display enough colors.

When you hear terms like 10-bit display and processing (vs 8-bit) or Deep-Color, these are things trying to eliminate this problem.


Try watching a blu-ray, and see if it happens there as well. Blu-rays will have more than enough colors to properly show the gradient, so if it is still there you know it is the display. If not, you know it is the source.


Judging by the fact that this is happening on SD stuff, I would guess that it is likely the source material does not have enough colors.

Yup that's what I'm seeing, I'll check it out with Casino Royale this Sunday by which time it should hopefully be in my possession. I'm not so concerned with the SD stuff as I expect it there, I noticed mostly in sky shots in FFXII and a few areas in Mario Galaxy's cutscenes. It's the fact that it's in the HD games as well that bothers me, I just got done with Crackdown and could notice it in the sky in that game as well albeit to a lesser extent. I suppose the MS Games Studio graphic and the 360 startup graphic could be compressed enough to present this problem.


I mostly just wanna make sure it's inherent to the TV and not a defect as I only have until Tuesday to return it and the box I need to take it back in will require a 3 hour round trip drive to pick it up. It would suck if I had to return it to since that would be the second TV of the same model, last time it was a dark spot on the screen though I suppose the banding could have been there but I never noticed.

Ok, now seeing I'm it in my desktop background when I use it as a second monitor for my computer and when I went to the Gametrailers website there were weird lines of color interspersed between the gray and dark gray lines that make up the border on the site. I also saw it when I was playing Worms earlier today in the background shots. Is this normal for this TV? I find it hard to believe there's a problem with all the sources especially since the Gametrailers website looks fine on my MacBook Pros monitor and there's no banding in my desktop background on it either.


My dad's coming to visit tomorrow should I tell him to bring the box and return it? Or is it not gonna make a difference and is the next TV gonna have the same problem?
