Intensity doesn't do 1080P - only 1080i

It can be very tricky with the frequency.
I recently had one which wouldn't display 60Hz - it only did 59.94...

I think escueto only had VGA output - so direct connection not possible - in some cases can work fine... But not always.

Intensity PRO is a good cheap option and using a scan converter allows maximum flexibility and compatibility.

Epiphan can suffer greatly from latency and low frame rates - there are much better options for MacPro - but may be the only option with a MBP or MacMini.
