Why does my PC say “non-optimum mode” when I start it?

When I turn on my PC it opens with a black screen and says “non-optimum mode recommended mode 144×900 60 Hz.” None of the keyboard or monitor buttons work.

Now I am in safe mode with networking and looking for help. I’ve found many who have the problem but not a solution.

I have an NVIDIA GeForce 7300GT video card and a Samsung Syncmaster 920nw monitor.

    In safe mode, set the display mode to VGA. Restart computer and install video card driver.

    Hi Edvinas
    Try the latest video drivers from here -

    If it is still the same then you need to adjust your settings here -

    Select the resolution mode at 1440X900 @ 60Hz and it should go away.

    uninstall the VGA and boot from the onboard.. uninstall the VGA driver and reconnect the VGA. then you'll be asked to install the driver again! you have a resolution problem!

    Just change your video display mode to 1440x900 and the message should go away.
