Monitor turning to black

[dennis23]

I use 3 monitors for gaming and after several hours, the middle monitor would start turning to black for a few seconds and then back on again. This keeps going until I exit the game. The power indicator would still be on throughout that period. The kind of black that the monitor display is the one without any backlight, like when the monitor is off. This has happened several times already. I'm using 3x Dell U1414H. Any suggestion is appreciated.

I need to figure out if it's my monitor of my GPU that is giving the problem

Then just unplug the another 2 , and using the working set power clog , and test it using onboard video . that's the most basic test
