Is the HDMI hardware capable of deep color mode?

Hi,

Is deep color mode enabled on Jetson?
If not, is it the hardware or the software that is not capable of it?

Thanks.

Hi theCuriousOne,

Could you describe more about the deep color depth you need? Is it a RGB or YCbCr one?

Hi WayneWWW,

I am looking to send out RGB444 10/12 bit from the HDMI.

Hi,

TX2 HW can support RGB444 12 bit. I am checking if our SW stack also supports it.

Thanks.

EDIT: We support 8/12 bpc RGB.

Hi theCuriousOne,

12 bpc RGB is ready in kernel. Please give it a try to see if works.

Hi theCuriousOne,

May I ask your usecase for 10/12bpc RGB output? This would help us enhance our support scope. Please kindly share.

Thanks.

Hi WayneWWW,

We are using to use it to output deep color images that we capture using a camera module. I am trying the latest kernel and I see that I am not able to create EGL frame buffers of 10 or 12 bit. Is there an application that I can use to verify the 10 bit pipeline?

Thanks

Hi theCuriousOne,

Just confirmed internally. 10bpc/12bpc are not verified. libDRM may be a good start and I suggest to enable 12bpc instead of 10, which seems even not enabled in kernel.
