We had a problem that is the output color is different between hdmi and dp.
We debug it and found:
1,the pixel_depth is different, hdmi is NV_SOR_STATE1_ASY_PIXELDEPTH_DEFAULTVAL, but dp is NV_SOR_STATE1_ASY_PIXELDEPTH_BPP_24_444
2, the cmu is different, the cmu_enable of hdmi is 0, but dp is 1; tegra_dc_get_cmu----hdmi is default_limited_cmu, but dp is default_cmu.
we try to set cmu_enable is 1 on HDMI port and change it to default_cmu, but
it is valid, the display color difference still remain, and dp port show video slower.

we upload the dmesg log for help to analyze.
help to check the pixel_depth and vmode is full range or limited range.
where to config the color in code ?
You did not tell us the query in Chromatic aberration probelm , and we can but create the new case.
up to now , you did not answer my question.
you just see cmu_enable, we think hdmi and dp color config not just cmu.
we had ask questions for pixel_depth and vmode, Don’t you see?
