External display won't go higher than 1024 X 768


  • I have a Lenovo G580 running Windows 8 and have it connected to a DELL flat panel monitor (about 6 years old) -- when I first got the machine, I had Windows look and install the latest driver for the display and for a very brief moment, I could change the resolution of this display. 

    The next time I restarted Windows 8, not only did the behavior revert to 1024 X 768 but it also became disabled in the Control Panel.  Every once in a while, I will disconnect and reconnect my machine and my display will go back to a normal resolution.  The next time I connect and reconnect, my resolution is again back at 1024 X 768 and disabled in Control Panel.

    What gives?  By the way, I am also using a KVM switch that I need - I havent tested without it in play but even if it was causing the issue, I should be able to set this up correct?

    Unpowered devices can work intermittently depending on which other devices are running with it.  Unpowered devices lower the voltage.  The easiest way to find out is to remove it and see if it still crashes.

  • This kind of issues are caused by device drivers. Not related to Windows 8. I suggest you contact the devices manufacturers for more information.
