Stephen, out of curiosity, what does
your xrandr show as a max framebuffer size on your quadro?
mb@host:~$ xrandr | grep maximum
Screen 0: minimum 320 x 200, current 11520 x 1200, maximum 16384 x
16384
This was a big limiter for me, in the past I couldn't figure out
why my old ATI 5800 card with 6 ports wouldn't support a full,
single framebuffer, but was internally limited to 8192x8192, with
the 6xxx+ supporting 16384x16384. Xorg wasn't too forthcoming
with that info, and it was prior to xrandr support in their
drivers, so totally left me scratching my head until escalating
with AMD support to an engineer with a clue that told me that.
With the advent of 4k displays, they still seem limited to that,
which means I can only do 4x wide until vendors give to open that
up.
Thanks!

After dealing with them for a good 5 years as the only real
viable option to run my displays, only to be wrought with
constant disappointment, problems, and frustration. Buying
highly overpriced quadro cards might be money well spent at this
point, but I still despise nvidia that they're really little
other than rebranded, and marked-up normal video cards with
driver-locked (to bios-id) features.
That said, going to set up some ebay agents to look for decent
quadro's to snipe. I had good luck getting my last few amd
cards that way on the cheap, gotta love jbidwatcher for cheating
some other person with a last-second bid.
Thanks as always for the input Stephen.

I have almost given up on ATI, if i want just
multiple screens i would look into the Quadro NVS cards.
Such as the NVS 510 or the K1200. They may be very
proprietary to get running, but my success with Nvidia cards
in both linux and windows really makes it worthwhile. These
cards will only do a single monitor, but they are cheap
enough to run 2 cards with reasonable usability. or one NVS
and one more Gamer friendly card.
