Quantisation Range - Full/Limited - with non HDMI connections

So, my original thread was closed with no useful information provided.

 

Hello Eugene7,

Thank you for patiently waiting.

The answer is yes, you will need a native HDMI* output, the output signal is not decided by the Intel graphics, it is handled by the Original Equipment Manufacturer design, motherboard, and Operating System.

To get that specific information, our best advice is to contact Microsoft* directly and ask for your system specs and design.

If you need any additional information, please submit a new question as this thread will no longer be monitored.

That is of no help as a solution, as it is the graphic card/chip set that manages output signal range, potentially based on the display's EDID information.

Can you please find some one with actual knowledge/understanding to respond to what is very basic question.

 

To reiterate, when the connection from the PC is NOT a direct HDMI connection (so the connector is DP, USB-C, etc), how does the Intel Graphics Chip Set decide what the output signal range should be - Full or Limited?

Please be precise, and explain exactly what defines the output range.

Hello Eugene7,


Thank you for patiently waiting, after reviewing internally this is the official response: For Non-Native HDMI scenarios, the driver enables Limited Range for CEA Modes and Full Range for other modes.

Well, as that is all part of EDID, that something.

But what Data Block, and Byte is used to make the decision as to the range to use?

I did ask for specific information.
