Dell Thin Client Screen Issue

I'll preface this by stating that I don't normally deal with network related systems in the work place.

We recently purchased a handful of thin clients to accommodate bring our inteal software to the shop floor of our manufacturing facility. However, the thin clients aren't displaying correctly on the monitor (see image below).

There is no issue with the camera or quality of the image. This is what it looks like on the monitor with the pink-ish lines ruing diagonally across the screen.

We ordered 6 of these thin clients, and so far we've tested 2 with the same results on two different brands of monitors (MonoPrice and Dell), which work fine with other terminals w/ same VGA cable.

Specifications:

• Dell Wyse 1003-E03 thin clients
• Windows Multipoint Server 2011
• I believe our admin tried installing some drivers from Windows Server 2012 for these clients

Does anyone have a solution to this or tips on how to troubleshoot this issue?
