Here's my setup:
PC ----HDMI----> AVR (Sony STR-DN840) ----HDMI----> TV (Panasonic P60ST60)
Nvidia GTX 670
Here's the problem:
I have all my devices hooked up to my TV through my AVR (cable box, PC, etc...) and all non-PC devices display perfectly. When I display my desktop or browser on my TV, everything looks correct. When I open a media player (XBMC or PotPlayer) and try to play any of my DVD or BD rips (.VOB straight off DVD or .MKV off BD, all uncompressed), the colors are really really dark. Night scenes are unwatchable and even scenes inside of lighted rooms are darker than they should be. I know my TV is calibrated correctly (or very close) based on my other input sources. I have used the Windows color calibration tool on my TV and can't get the gamma setting quite right, but it's pretty close. Oddly enough, playing videos on VLC displays them correctly on either my monitor or TV (but no DTS passthrough so no good). When I watch the video on my computer monitor, it looks fine. When I pause it and drag the player over onto my TV, it still looks fine. As soon as I press play, the scene instantly darkens. The reverse also happens. If I drag it onto my monitor while paused, it looks dark. As soon as I press play, it displays correctly. I've changed my settings in Nvidia Control Panel to output 16-235 on my HDMI out to my receiver, but it doesn't have any effect at all. Like I said, I've tried multiple media players, and they all look terrible on my TV but great on my monitor. I doubt my receiver is the problem because other sources look correct. I'm fairly certain from researching elsewhere that the problem lies in the colorspace issues others have seen (0-255 vs 16-235), but all attempts to correct this have failed. Any suggestions?
The best results PQ wise is for your PC desktop stay in full-range. Your NVidia card driver stay in full range, and you configure EACH video player app to output full-range instead of limited (as majority of video sources are limited). And set up your TV to full range as well (your TV is capable of it). That is assuming your Sony receiver won't get in the way (clipping BTB and WTW). But when you switch to other sources, you have to change your TV to limited range as ALL other video equipment output limited range as standard.
If that is too much trouble for you, you can configure your NVidia card driver to output limited range for desktop, and you still need to configure EACH video player app to output full-range so it then be converted to limited range by the driver on final output. This requires no changes to TV settings and any receiver should pass it without problem.
VLC outputs either full-range or limited range depending on which renderer you choose. WMP always output full-range. WMC always output limited-range but can be altered via a registry hack. etc. etc......
It could be a bad thing as well because your images and videos get converted from one color space to another and sometimes twice.
