Thanks for clarifying. On my other G550 I have a 1600x1024 monitor on what appears to be a single-link cable. If I switch from DVI-digital to DVI-analog *on the monitor* the picture goes away, so I was getting
very confused.
This is [EMAIL PROTECTED] with a 108MHz clock, well under the 165MHz limit.
There is something else:
The *analog* signal (speak: DVI-A) is (partly) transferred on the extra pins, outside of this 8x3 block. There are (up to) four pins in a square, with a ~2mm wide "key" pin in the middle. If these pins around the key pin are missing, this is a digital-only cable.
I have pins 123..678 in each row, ie I am missing a 2x3 block in the middle of an 8x3. I take it this is single-link.
Think so, too. Might be DVI-A, though - see above.
I should probably stop thinking about what my G550 will do on my SGI 1600SW+MLA. 1600x1024 seems to break all the rules.
Should be possible using analog signals. But this is more a question for Matrox experts (which I certainly am not - don't even have such a card)
