I'm not sure how you can know what Alex really intended to say (that should probably be left to him ;-)), but that's not what he wrote: EDID != mode list, EDID is what comes from the monitor, the mode list is what comes from the card. > However, I have > also observed that Haiku did not boot in 1920x1080 when I hooked it up > to my TV via HDMI.

That can only be answered if you provide the EDID output of that monitor, as well as the mode list the VESA driver retrieves from your card. In any case, it's unlikely that this is a driver issue.
