We want to set HDMI output of i.MX6Quad to 24bit RGB4:4:4 Full Range.
We found the following thread.
We tried the following setting, however, the HDMI output does not become Full range.
- HDMI_FC_AVICONF3[YQ1_YQ0_YCC] = b'01
- HDMI_FC_AVICONF0[FC_AVICONF0_RGB_YCC]_[Y1:Y0] = b'00
Is the following information in "thread/430155" right?
Please tell me the right list if this is not right.
YQ1_YQ0_YCC = 00 Limited range (16 to 255)
YQ1_YQ0_YCC = 01 Full range (0 to 255)
YQ1_YQ0_YCC = 10 Reserved
YQ1_YQ0_YCC = 11 Reserved
[Y1:Yo] = 00 RGB (default)
[Y1:Yo] = 01 YCbCr 4:2:2
[Y1:Yo] = 10 YCbCr 4:4:4
[Y1:Yo] = 11 Future
Would you tell me the setting method of 24bit RGB4:4:4 Full Range?
Should we set HDMI_CSC_CFG or other register also?
When Full range / RGB setting, How does the set point convert it?
- RGB set to 0 => 0 output
- RGB set to 256 => 256 output
When Limited range / RGB setting, How does the set point convert it?
- When 0 is set in RGB value, what outputs it?
- When 256 is set in RGB value, what outputs it?
About these Full Range and Limited Range,
May I have a list of output for the input?
