How to enable Intel HD Graphics 3000 support HDMI deep color output?

Hi,

 

I want to output 12bit per component, i.e. 36bit/pixel, from HDMI.

I checked registry and found DeepColorHDMIDisable is set to 0.

But I can only get 24bit/pixel from HDMI port.  What's missing?

I checked Intel Graphics and Media Control Panel but found no where to enable this feature.

 

Thanks,

Sheng

    Below is the system information in case it helps.

    And it's verified the connected TV supports HDMI deep color by a deep color HDMI video signal generator.

    I also have this issue with my HD4000 on my I-5.  My projector detected deep color from my old blu ray player but it is not detecting it from my hd4000 on my htpc.  The reason is...?

    Comments made in reviews indicate that the 4000 can only handle 8bit colour - 24bit for RGB, 10bit colour is available from some AMD/NVIDA cards. This should not be much of a problem for your environment as while you may have a projector/blu-ray player combo that reports deep color support, current blu-ray disks are themselves only 8bit colour.

     

    The same is true for other messages posted here - the fact that the TV/Device interface may report support for up to 12bit colour it does not mean that the display panel or media has 12bit ablities.

    According to the link below, HD3000/4000 shall be able to output HDMI deep color.

    Quick Reference Guide to 2nd Generation Intel® Core™ Processor Graphics (HD Graphics) | Intel® Developer Zone

    The only problem is how the Intel graphics driver handles this feature although h/w itself may seem to support it.

    It could be either the driver completely disable it and only enable 8bit, or there is a secret switch or something.

    That's why I posted the question in the first place.

     

    To response to your comments:

     

    1) NVidia cards

        Yes, NVidia GT430 or anything higher can output 36bit/pixel on HDMI port.

        I used DirectX 10.1 and set R10G10B10_A2 format, then Nvidia driver nicely handled it and gave me 36bpp.

        When I took the same DX rendering to HD3000, only 24bpp is output.

     

    2) Blu-ray and 8bit

        Yes, don't bother to try high precision on Blu-ray content as it's defined 8bit according to Blu-ray spec.

     

    3) 10/12bit TV

        I agree that HDMI interface supporting 10/12bit doesn't necessarily mean the panel does it as well.

        Most of the time, to reduce the cost, the TV manufacturers will only keep 8bit precision on panels.

        However in my case, the target TV has been validated to have 10bit precision by 10bit test pattern.

        The pattern was sent from a 12bit HD-SDI link via SDI2HDMI converter box with deep color enabled.

    i don't care what anyone says

     

    HD4000 displays normal colors on my VGA port, including deep black.

     

    but HD4000 displays crappy color on my HDMI port on the same laptop; Blacks show as dark gray, and gradients show banding, and overall color looks washed out.

     

    HD4000 is perfectly capable of displaying the color, as evidenced by my VGA port output.

     

    it's the HDMI port that is the big issue. What the hell, Intel ?

    HD3000 had the problem, and it carried over to HD4000. When is it going to be fixed?
