Warnings:

Block 1, CTA-861 Extension Block:
  IT Video Formats are overscanned by default, but normally this should be underscanned.
  Vendor-Specific Data Block (HDMI), OUI 00-0C-03: Progressive and Interlaced latency values are identical, no need for both.
  Video Capability Data Block: Set Selectable YCbCr Quantization to avoid interop issues.
  Video Capability Data Block: S_PT is equal to S_IT and S_CE, so should be set to 0 instead.
EDID:
  CTA-861: Multiple native progressive timings are defined.

Failures:

Block 0, Base EDID:
  Vendor & Product Identification: EDID 1.3 does not support week 0xff.
  Detailed Timing Descriptor #1: Mismatch of image size 708x398 mm vs display size 1150x650 mm.
  Empty Descriptor: Use Dummy Descriptor instead of all zeroes.
