I have SAM440ep-mini and I use 1920x1080 60hz resolution via DVI.
But I can not recommend it.
When compositing is enabled one can use only 16bit display on WB and also then one runs out of VRAM (64MB) very easily.
32bit works, but even a single application often gets the system out of VRAM.
And it seems HW acceleration does not work reliably if less than half of the VRAM is free.
And low VRAM situations tend to cause crash or lockup pretty fast.
As an end result, I'm considering moving to lower resolution but with more colors.
