Warnings:
Block 0, Base EDID:
Vendor & Product Identification: The serial number is one of the
known dummy values, it should probably be set to 0.
Block 1, CTA-861 Extension Block:
Video Data Block: VIC 16 and the first DTD are not identical. Is
this intended?
Display Product Serial Number is set, so the Serial Number in the
Base EDID should be 0.
Add a Colorimetry Data Block with the sRGB colorimetry bit set to
avoid interop issues.
EDID:
Base EDID: Some timings are out of range of the Monitor Ranges:
Horizontal Freq: 15.734 - 75.000 kHz (Monitor: 24.000 - 80.000 kHz)
Failures:
Block 1, CTA-861 Extension Block:
Missing VCDB, needed for Set Selectable RGB Quantization to avoid
interop issues.
EDID:
CTA-861: Native progressive timings are a mix of several resolutions.
EDID conformity: FAIL
The failure is coming from sink_supports_format_bpc()[1], but the flag
for DRM_COLOR_FORMAT_RGB444 should have been set from
update_display_info()[2] parsing the EDID.
Loading that EDID in via drm.edid_firmware has given me a console at
1920x1200@60 without any issues, so I'm a little confused as to what
is going on.
