I have to clarify/correct my original post:
Single Link is not directly limited as regards resolution, but clock speed. Single link cards/cables have a max clock speed of 165Mhz. All above this needs dual link.
165Mhz should last for up to 1920x1080-60Hz or 1280x1024-85Hz.
The monitor reports it's in 'digitial' in the onscreen displays.
Plus, I'm using a (single link) DVI/D cable. I can't
even force it to analog on that cable via DigitalScreen{,1,2} "False".
(Could it still be fooling me and doing analog somehow?)
Don't think so.
I really like your point about the dual-link card/cable. I may go get a dual-link cable and see if it has an effect on the Iiyama au4831d. (And/or if Dr.Aitchison could report on his cable?)
Erm, I don't think this will help. Since Matrox always and everywhere states that the maximum resolution is 1280x1024 the card is very probably a single link card. Hence, a dual link cable will not help you either.
Lastly, how can I know if a card is dual/single link?
Good question. Card manufacturers generally don't seem to like or use these terms. Typically, they target on Windows users who think in resolutions only.
p.s. Re: Veit's question about 60hz vs 56hz: I'm sure. I went and double checked: at 60Hz I get a blank screen for 1600x1200 and see this in the log:
Look at the dotclock. If it exceeds 165Mhz, the DVI connection very probably will fail to be stable.
