Bought this for a long term project. Great price. The 19" sq. screens are okay, but I have already changed them out to larger, rectangular screens. Screens supplied are VGA. They only sent one VGA to Display Port converter so I got another one. Cost around $10.00. Only issue is that it goes blue screen every so often for what appears to be no reason... It is time consuming to have to re-log in and get programs running agin. Otherwise, I happy with this unit.
