corza13 Posted June 24, 2008 Posted June 24, 2008 Guys, I posted this as part of another thread, but it didn't get any attention so asking for assistance in this dedicated thread. I am having issues with this TV when enabling xvYCC colour on the menue. I have an Oppo 983H and Pana BD30. They both support it and is enabled in all menus. Onkyo 805 has this setting enabled also. When I stop a DVD on the Oppo and then try and play again, the screen goes green over the action being played? I do not have this problem when xxYCC is set to off in the Samsung menu? I have tried sending starigth from both DVD players as well so it is definately a TV problem. Anyone else have this problem or heard of it. I would like to resolve this as I see a nice difference with xxYCC enabled Any help appreciated.
corza13 Posted June 27, 2008 Author Posted June 27, 2008 ok, I can only assume I am on an island with this issue. Can a good samaratin forum member try and replicate this problem? Does anyone else have xvYCC colour enabled on the TV?

ford Posted June 28, 2008 Posted June 28, 2008 what do you mean?I am not talking about deep colur. I am talking xvYCC Here is a bit more to explain that its all a waste of time: Here's a simple way to think of xvYCC. Suppose you are watching an old black and white TV program on your modern color TV. The TV is able to represent more range of color than happens to be used in the black and white program. But you don't see any difference because the program content is not taking advantage of it. The sky in the black and white program is not blue for example. Nor is the grass green. They are all shades of gray which is all that's present in the black and white TV program content. Now suppose you are watching a color TV program on an old black and white TV. Since color TV is designed to be compatible with old black and white TVs this will work. But of course you won't see any color in the TV image. The sky will be light gray even though it might be blue in the program content. The grass will be darker gray. xvYCC is like "color" in this simple example and RGB and YCbCr are like "black and white". "Color", on the face of it, is better, but only if everything in the video chain -- capture, processing, and display -- ALL support it. Clearly to get any real advantage you need for everything to be "color". The same is true for xvYCC. The original content (whatever you are filming) has to take advantage of it, however you are capturing the content (camera or computer or whatever) has to be able to capture it, the data storage or transmission format has to support it, the image processing has to carry it through without limiting the range of colors, and the TV has to be able to display the full range of it. If not, there's no advantage. ------------------------------------------------------------------ There is currently no mechanism to get mass market content (commercially produced movies or TV shows) into people's hands in the xvYCC color space. HDTV won't do it regardless of how it is transmitted (off air, cable, or satellite). Nor will HD-DVD or Blu-Ray discs. It's not part of those formats. And there is no expectation that this will change for years. xvYCC color space content CAN come from specialty consumer products (like the Sony camera), or from computer rendering -- perhaps from home computers. But you are *NOT* going to be able to tune into a TV channel to see it or buy a movie disc at Blockbuster to see it. Not for years. Think how long it took HD-DVD and Blu-Ray to get launched in the first place. For people who buy an xvYCC capable TV to view HDTV channels or HD-DVD or Blu-Ray discs, it will be like having a color TV with only black and white programs available. And in fact you are likely to find that many TVs claiming to support xvYCC in the near term *DON'T* actually even try to display that full color range. They will simply accept the data and strip it down to the color range of more normal RGB -- or possibly just a little better. Just like a black and white TV showing a color TV program and claiming it "supports color". --Bob -------------------------------------------------------------------------------- HDrocks: Without xvYCC.

Thaks for the detailed explanation Bob Why then when I enable it on the Samsung does it CLEARLY have a better picture from DVD and Bluray discs. It is definately more detail, smoother, more natural colour. My Oppo 983 supports it, as does the Pana BD30
shano23 Posted June 29, 2008 Posted June 29, 2008 I think the PQ looks crap with xvYCC on, everything looks unbalanced and unnatural. Corza13 have you got your tv properly calibrated in the first place?
