|

I'm having a little difficulty understanding what I should do regarding my attempts to calibrate color on my display.
I have an Oppo 983, coupled with a Samsung PN42A450 display, connected via HDMI and upscaled to 720p resolution. If I feed YCbCr from the player to the TV at HD resolutions, my display seems to fail the colorspace conversion (I get a large error in green luminance when switching from SD 480p to HD 720p/1080, virtually decreases by almost 30%). My other alternative is to feed the display RBG Video Level from the player, where I don't receive the luminance errors. My question is what do I now do regarding color calibration of the display?
What color standard to I calibrate to? I've read on numerous occasions where people say "RGB is RGB", but what does that mean exactly? I think they were implying that I should not be able to adjust color, as the player is now doing the decoding (as is the case when I hook up a PC via VGA; I cannot adjust the color on the display). In this instance, however, it still allows me to do so; the three choices being Auto, Native, and Samsung's CMS controls. Obviously I would prefer to use the later, but I do not know what color standard I should be calibrating to for reference.
If I go back to feeding YCbCr to the display, could I compensate for the display's failed colorspace conversion utilizing Samsung's CMS controls, or would color be borked no matter what I do? The settings are kinda extreme (Green luminance slider having to be pushed to 88, on a scale of 0 to a 100!), but it seems possible.
I would appreciate any help provided.
