Hi there,

I have 4 identical monitors. So I decided to buy (not to expensive,
around 100USD) quad head graphics card. I do not need anything
particular. Only office applications, no gaming. The crucial thing is
that I would like to be able to span a single window across all 4
monitors. I found following cards:
Gigabyte Radeon HD7770 OC

Any recent radeon hardware supports multiple monitors just fine with
the caveat that if you are using more than 2 non-displayport monitors,
they have to all use the same clock (you are limited to two
independent clocks), or you need active dp adapters.  If all of the
monitors are identical, it shouldn't be a problem.
I mentioned the following radeon graphics adapter:
http://www.gigabyte.com/products/product-page.aspx?pid=4278
So definitely it is capable of driving for monitors. The question is if it is possible to configure X server in such a way that all 4 monitors connected to this particular adapter are in one logical DISPLAY. At the moment I use two dual head ATI FirePro 2270 graphics cards. As a consequence I have two logical (dual-monitors) DISPLAYS and I'm not able to span a single window across more than 2 monitors.
