If I set video=3DHDMI-A-1:d nothing comes out the DVI port and if I set= =20 HDMI-A-3:d nothing comes out the HDMI port. This is rather confusing.

The machine is=20 unresponsive for 2-3 seconds when this happens. Sure, specifying the EDID as firmware is a work around, but it's a work= =20 around that isn't working as intended on this hardware, for whatever=20 reason. Seems like someone would be interested in fixing it? I've got a= =20 machine I could provide some access to? Mark
