I have been running a dual monitor display for over a year now and it has suddenly decided to only turn on one screen.
Though when I restart my computer the screen that is not currently loading would load the boot up menu (windows logo and other info) but then not load desktop. Where the other screen would turn on.

Greetings donnellbob1,

Depending on your OS, go to Control Panel>Hardware & Sound>Display and click Change display settings. In the Multiple displays field, the setting should be "Duplicate these displays" or some similar option.

The setting may have been disrupted during a particularly large Windows update.

Cheers,
GreyCatz.
