Server does not control the screen directly - we use chromium browser. So any touch screen that linux supports should work. The only thing is that our image will not support it out of the box. You need to add the driver as described in the screen installation instructions. By default our image uses hdmi output.
That said the screen resolution is the minimum required so display informations is naturally a bit more reduced then on 7" display which has more place. But you should be able to still use all functions.
