At a guess it is the refresh rate the video card is sending to the video out. What is the Max Resolution of the monitors and refresh rate ??
I would think there is a program to be able to setup the driver refresh rate and resolution don't use window drivers get the ones from the makers of the card rather than using the default nivida drivers

I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.

Most likely the LCD panel is defective. Since this is an older product it more cost effective to purchase a newer product with more features and performance.
