viewtopic.php?p=2127581#p2127581Among other things, when using the HDMI to VGA adaptor cable, edid-decode reports a CTA-861 extension block (block 1) which does not exist when a native VGA source is connected to the monitor. It also alters block 0 to report a digital, rather than analogue display with no analogue voltage levels reported, and the screen type as unspecified, which is reported by edid-decode as 'monochrome or grayscale display' (per Raspberry Pi engineer dom's description of a similar EDID in a thread I can't find right now).
