    Monitor turns off and on spontaneously

    tingholm

      I have three Dell Ultrasharp 2415 monitors connected to my PC.

      First I wanted to Daisychain all three on displayport, but could never get the last monitor to display anything.

      Then I Daisychained two of them and connected the last using DVI-HDMI cable.

      But the monitors on the daisychain turn off for a second and then turn back on all the time. Sometimes only the last on the chain, sometimes both.

      I tried to connect only one monitor using displayport, one using DVI-HDMI and the last one using external USB graphics. Still the monitor on DP turn off and on frequently. The other two allso did, but not nearly as often.

      I tried to connect only one monitor using DVI-HDMI and the other two using two external USB graphics. Now the blinking has almost stopped, but still occurs.

      I tried to update the driver: https://downloadcenter.intel.com/download/25588/Intel-Graphics-Driver-for-Windows-7-8-1-15-36-

      I tried to connect the power to UPS to eliminate power issues


      Any ideas how to get a stable image on my monitors?
