Default Re: dual external displays on Quadro FX 770m, possible?

Now I'd like to connect another 24" (1920x1200) via HDMI.

So far, I couldn't get it to work, maybe the 770m has only two TMDS lanes, already consumed by the dual-link connection? Or is the HDMI port wired in parallel to the dual-link DVI-port, using one of the two links?
It ought to work. Please see the forum sticky posts about how to report a problem.

Then it seems not to be possible to load two CustomEDIDs, if I have two lines in my config, e.g.
Option "CustomEDID" "DFP-1:/edid1.bin"
Option "CustomEDID" "DFP-2:/edid2.bin"
only the first line is evaluated. comma separation like "DFP-1:/edid1.bin, DPF-2:/edid2.bin" doesn't work either.
As per the documentation, you need a semicolon instead of a comma.
