Google indicates that someone might have worked on something called HMD-EXT to be standardized by VESA for EDID, but no documents seem to exist for that. Thierry

We had someone working with VESA on exactly that and I thought that had shipped, but we found the same thing: the extension was never released and there's not currently a standard way to tag HMDs at the EDID-level, which is very unfortunate, as you'd want the lowest levels of the system to be aware of the HMD-ness of a display. You would never want to bring up a text console on one, or any sort of non-distorted content. I'll look into getting that effort back on track, but in the meantime it looks like an EDID blacklist somewhere might be our best bet.
