    Ta both. No, I did mean I swapped the outputs. Left working prob. just coincidence. I do find if I leave on at mains overnight there is no problem. Turning on about 10 mins before using didn't work tho.

    So the left monitor works fine but the right doesn't?

    Swap over inputs from the graphics card(s) - you've already swapped the cables but I didn't see you mention that you've tried output A into monitor B and vice versa.

    If the left monitor still works after that swap about then the fault may be with the monitor rather than the PC hardware/cables.

    Failing PSU or graphics card? If monitors power up but no output on screen (light on but nobody home) then maybe there is insufficient power on cold start up, and rebooting or leaving power on keeps enough juice in the circuits to avoid the problem.

    Can't you just leave on at mains until get opportunity to try a different PSU or graphics card? They should be drawing virtually no power when turned off but powered on at mains anyway.

    The left monitor may be working better if it has 'wake up' circuits for video received that require slightly less power than the right monitor.

    Is your graphic card definitely able to support both monitors running at your required resolution?
    Cheers Woohoo. Not using any adapters. Yeh, had no problem with same monitors until a few months ago. Wonder if Intel driver could be problem, notice it was updated in March which could have been when problems started. Tried rollback but says no previous version available.

    Not sure it's related to Windows, I don't get usual boot text showing when the monitor doesn't work.

    Tried all the obvious stuff and suggestions on line, changing leads, using different monitors, pressing Win-P, checking got latest driver version, disabling/enabling, uninstalling reinstalling etc. No solutions. Any ideas, needs new graphics card maybe? Ta.

    PS One lead is vga and one dvi. Daftest thing is that it's usually the monitor on the left that works regardless of which lead is plugged in. Weird.
