-Warnings:
-
-Block 1, CTA-861 Extension Block:
- Colorimetry Data Block: Set the sRGB colorimetry bit to avoid interop issues.
-Block 2, DisplayID Extension Block:
- Vendor-Specific Data Block (0x7f) (Apple), OUI 00-10-FA: Expected PNP ID but found OUI.

Failures:
-Block 1, CTA-861 Extension Block:
- Required 640x480p60 timings are missing in the established timings and the SVD list (VIC 1).
- Missing VCDB, needed for Set Selectable RGB Quantization to avoid interop issues.
Block 2, DisplayID Extension Block:
- DisplayID Base Block has no product type.
- Expected 0 DisplayID Extension Block, but got 4.
- ContainerID Data Block: Use of DisplayID v2.0 tag for DisplayID v1.2.
- Vendor-Specific Data Block (0x7f) (Apple), OUI 00-10-FA: Endian-ness (le) of OUI is different than expected (be).
- Vendor-Specific Data Block (0x7e) (VESA), OUI 3A-02-92: Use of DisplayID v2.0 tag for DisplayID v1.2.
