It ought to be simple enough to write a software genlock driver that chooses one of the cards as master and tweaks the pixel clocks on the other ones to bring them into sync with the master.

Linus Torvalds wrote: Ok, this is pretty off-topic, but I'm wondering what the status is for open-source support of 3D-capable drivers for such studly monitors as the IBM T221. It is a beast. A couple people in my group are trying to convince management that we need one, but it's a hard sell (as I'm sure you can imaging). I'm CCing a couple people who will know better, but I'll tell you what I can recall. If you run it from a single DVI input you're only going to get about 7Hz refresh rate. I believe that we briefly had one running on some sort of Nvidia setup using dual DVI conntects, and we got about 18Hz. It should be possible to drive it with a Radeon 8500 type card. One of the 9100 chips would probably be your best bet. You wouldn't get any accelerated 3D on it, though. It could be accelerated, but our current static back-buffer / depth-buffer architecture won't allow it.

Re: [Dri-devel] High-resolution monitors (T221)
Linus, Some dell OEM radeon cards offered Dual DVI ports and I believe there are some other oems (tyan?) that will be offering Dual DVI cards. the radeon 9000s and newer only have one tdms trandsmitter built in, but an additional external one can be added on to drive the second DVI port. for multi-head 3D on radeon hardware, check out my mergedfb patch: http://bugs.xfree86.org/show_bug.cgi?id=276 Unfortunately, due to a hardware limitation with the scissor registers, you are limited to 2048x2048 for 3D. your framebuffer can be as large as 8192x8192 (limits for the 2D engine). you can use mergedfb at resolutions higher than 2048x2048, however, any 3D windows larger than 2048x2048 will not display.

I don't know of much cards which have dual-link tmds. Even all the Quadro4 XGL cards only have 2 single tmds links. The Quadro NVS 400 (PCI) supports 4 single links, but I have no idea if there is linux/3d support in the driver (basically I believe this is just 2 GeForce4MX 420 chips on one board). If you get the Quadro FX 2000 or 3000 (but not 1000), it has one dual-link and one single-link DVI connectors. All ATI consumer cards have only 1 single tmds link (there were announcements from tyan about dual-dvi cards, but the cards were apparently cancelled). The firegl cards (at least the newer ones based on the "gaming chips") have two single tmds links. The binary-only NVidia driver supports it at the full 40Hz frequency, so I know I can get the thing to work under Linux in case I decide to waste the money on it (or, preferably, convince my employer to do so ;) I assume you can get the 40Hz only with the FX2000/3000? The reviews I read stated something like 12Hz if they only used 1 dvi output of a Quadro4 XGL, and double of that (but with tearing due to sync issues in 3d - not sure if this is driver fixable) if they used both dvi connectors.
