As there are so many references in the datasheet that infer better color depth, I posted a more specific question in the processor section.
Below are some references from the desktop [socket 1150] datasheet [328897] that might have to be taken in context, yet it seems puzzling to me that Intel would have gone to the effort to make such a good sink & interface if the graphics core was not up to it. Also 10bpc is not so demanding, especially without the transparency. So until one can point me to the page(s) in the datasheet that evidence that the 4600 graphics cannot produce over 8bpc for the sink, or some more detailed documentation, I don't want to jump the gun :
page 27 :
Superior image quality with sharper, more colorful images
page 29 :
The 2D registers consists of original VGA registers and others to support graphics
modes that have color depths, resolutions, and hardware acceleration features that go
beyond the original VGA standard.
page 31:
The HDMI* interface supports HDMI with 3D, 4K, Deep Color, and x.v.Color. The
DisplayPort* interface supports the VESA DisplayPort* Standard Version 1,
Revision 2.
page 33:
The processor HDMI interface is designed in accordance with the High-Definition
Multimedia Interface with 3D, 4K, Deep Color, and x.v.Color.
Why would one bother mentioning the above if the processor is unable to use the features ?
