Hi guys, finally got a remote working on xbmc so trying to use it more, but rgb levels are the next thing holding me back.
Videos are way to dark because they're being expanded to 0-255, when they should be 16-235. Combine this with LCD's notoriously bad black handling and you get, for me an unusable picture. Its not a problem when in use with my projector, as that allows you to switch between standard and enhanced, but my monitor (28" Hanns-G) does not.
SO? Is there anyway to sort it? Either in xbmc or ATi's display driver? I understand tweaking ati's avivo settings wont affect xbmc as it uses full opengl output rather than a video overlay? Is that correct?

That's also a big issue to me.
One of the reasons that makes me use the external player patch (reclock being the other one).
ASFAIK there is no way to change it right now. I wish to know if someone is working on it.

Just change it in the ATI vid card settings? Jsut change the dropdown from desktop to 3D settings. Or something like that. Then change the contrast and brightness.

You need to change the Pixel Format in your ATI control panel from 'Full RGB' to 'Limited RGB'.

Do any of you guys know if it is possible to do something similar with nVidia cards?
Thx.

It would be nice to have options for this inside XBMC. Sometimes a video has wrong levels encoded and a custom shader would be great in these situations.

Found the option in there, had to update to 8.12. Unfortunately, it doesn't change a damn thing! My options are
4:4:4 Studio (Limited)
4:4:4 PC Standard (Full)
Both are definitely the same, tried with patterns up and some videos playing whilst flicking between them.
I wonder, could it be a limit of my dvi-hdmi cable?

Thx for the reply.
But I have tried this on the past, and it doesn't work.
It works for every player I have (MWP, MPC and Zoom), but it doesn't work for XBMC.
One easy way to see if it works for you or it doesn't is to turn the SATURATION slider all the way down. All of your player wil be B&W, but XBMC will still play them with normal color.
Thats probably due to the fact that the system sees it not as a video player, but as an OpenGL application.
