Windows 10 dual-monitor issue

  • This may be specific to the combination of my hardware and Windows 10, but I have found that if I have Opera 31.0 open on one monitor maximised and then drag it to the top of another monitor, the entire Opera window is blacked out.

    I did not have this problem with Windows 8.1 on the same hardware.

    My system is a little odd in that it has a slave Intel graphics card and a main NVIDIA card.

  • I run Windows 10 on both my computers and a dual monitor setup on one of them with no problems such as you are describing?
    The graphics card setup may be your problem, there could be a conflict somewhere that is affecting your browser?
