Default Re: Wrongly rejected interlaced modes from EDID?

There is a quite detailed article about EDID in Wikipedia. This answers your question about the native res (it is in the EDID but in a convoluted way and it seems unwise to rely on it for checks and calculations, see it as a hint only).

Many values are stored in the EDID in minimalist number of bits with tricky formulas.
This easily results in mistakes.

The real vertical refresh is PixelRate / (HTotal * VTotal).
