    these things really dont like working at high resolution

    any difference you indicate is extremely unlikely to be anything to do with server or non-server OS-
    Only one output in use, Mini Display Port with Apple Dual Link DVI adaptor and Triplehead on. 3x 1024px x 768px @ 60hz.

    The machine came with a fresh install of OS X Server on, I ran Catalyst and the content and results as above, unsatisfactory. Settings were as per usual, services turned off, spotlight off etc.. All from internal SSD.

    After installing fresh OS X, all good, no problems at all.

    Again, this was outside and we were in a hurry so little chance to experiment, and this was back in October last year.

    when apple released the mac mini servers - the os versions available at that time werent in sync with the hardware - so some drivers werent there if you swapped or changed things around

    you have to be conservative in expecations off graphics performance on these things-

    In agreement with Richard...

    The graphics suck.

    There is no graphics memory. The GPU is very small and very basic. It uses system memory and gains this system memory at the expense of the CPU performance. The CPU is also busy accessing the SATA controller so you'll also downgrade your playback performance.

    Triple head is a very very bad idea on a Mac Mini. Single output only 1920x1080 or smaller.

    It is possible to crash Catalyst on a Mac Mini by overloading the video card with very high pixel resolution such as a TH2G. They system tries to buffer too much memory to a paging file and the system will lock.

    This is rare but it has happened to me. (granted I obscenely overload things to test them)
