Had this (20"?) LED (LCD) monitor that would not take a VGA input, It kept flashing "Check Cable Signal - Digital". Once I connected a DVI cable with a functional DVI source, I could go into the menu and change the settings to allow VGA.

This is not an equipment or circuit failure, it's a poor design. Hopefully this will prevent someone else from pitching their fully-working monitor.

It would indeed let me enter the on screen menu, however all the menu options were greyed out (unavailable) until I plugged in a DVI cable with a functional source.
