BTW.: Here's another thread that (actually doesn't) sheds some light
on the xinerama+composite issue:

Default Re: Triple-Head Setup without Xinerama?

I was wondering if it's possible to use two different monitors with TH2G, e.g. 1920x1200 + 1600x1200. Non-symmetric resolutions aren't mentioned on their homepage or in any review I just read, so I'm not very optimistic.. is there anyone who's tried something similar?

greetings,
Tub

While setting up my TH2G with the Matrox-Tool (for Windows), i only saw symmetric
modes, so my bet would be that the mix you desire is not possible. I recommend
sending an e-mail to the matrox support - my experience is that they are quite
responsive and helpful.

Yes only symmetric modes are supported. That is because the device just 'emulates' such a display shape. Non-symmetric shapes don't exist as monitors.

you mean, "non-rectangle shapes" don't exist as monitors? Both my 1920x1200 and 1600x1200 are 1200 px high, when put next to each other there's a nice 3520x1200 bounding box that could be emulated. But alas, if the device doesn't support it, it's pointless. Email to matrox is underway, I'll edit when/if they reply.

I'd like to add another monitor to my setup. Addicted to screen space and stuff. Right now I use this setup (not to scale)



where the notebook display is connected using synergy, hence no window dragging across the computers, but at least I can use one mouse and keyboard.

I'd like to buy another 1920x1200 (and some mounting stuff) to achieve this:



but I don't have a clue how to connect the third monitor without sacrificing something.
  • Adding a second gfx-board + Xinerama will disable composition.
  • TH2G on both 1920-screens will only work with 57 Hz, not a good idea either.
  • Connecting a 1920 and the 1600 using TH2G doesn't seem to work.
  • Adding a monitor to the notebook is not an option, since the notebook doesn't have a DVI port (and isn't permanently available anyway).
  • Adding a second gfx-board without Xinerama will disable window dragging on yet another monitor and require another taskbar.
So after all, it seems like I'm better off with my old setup. bleh.

Somehow I missed that both screens you want to add have the same height. I would say that it is possible to design such a device but I don't know whether Matrox supports this combo.

Hi Tub!

57 Hz on an LCD shouldn't cause you headache :-)

yeah, but I like to watch movies from time to time, 57Hz would lead to tearing, stuttering or skipped frames. I guess I'll keep my setup until affordable 30" displays appear.

oh, matrox support is quick:

Hi Mr xxx,
As you have noticed, the monitors on a DH2Go or TH2Go have to be
working on the same resolution.
Thank you.

I see. BTW.: i guess purchasing a second 1600x1200 LCD, instead, is not an option?

there are no cheap 1600x1200 monitors, the cheapest I found is 520 (the one I already got) - it has a good panel, TV in and everything, but I don't need that.

24" 1920x1200 with cheap TN panels are available for 300 or less.

So: no, I don't really want to buy a smaller monitor for almost twice the price
