Need powerful monitor testing solution

Hello, we are currently in need of a more powerful monitor burn in device, as of now we have been using a checker VI device that will allow simultaneous burn in of 6 monitors per unit. the tester pushes a 640×480 color bar pattern, we currently need a better solution.

prerequisites are:
1. unit must be able to run for extended periods of time
2. unit must have multiple monitor capacity
3. unit must be able to send test patterns at resolutions up to and including 1280×1024
4. unit must be cost effective for our company

if anybody knows of such a unit, advice would be greatly appreciated
