Comment 4 for bug 470422

So you have the IIyama monitor attached to the HDMI output of the computer, but is it connected to a HDMI or a DVI input on the monitor? The EDID listed in Xorg.0.log is only 128 bytes long, but as far as I know, HDMI devices are required to have extension block making the total block size bigger. Does `sudo get-edid >hdmi-edid.bin` make only a 128 byte file, or could it be that X doesn't read all the blocks?
