I'm in a tight spot here as this is a charity's main pc. I'll get the full setup when I'm back the this morning however here's the basics.
Windows 10 on a hp small form factor pc, Nvidia graphics card and a usb VGA graphics card. The two ports on the Nvidia card are display port, one runs a monitor, the other a projector. The usb runs a wall hung monitor. All have been working perfectly until last night when a child decided to pull everything out the back of the pc. Now I cannot get the projector working again. I don't know what's happened, I've done the driver reinstall and that didn't really do anything. I'm at a total lots and this pc needs to be working by 6 tonight. Help me!

Hi and welcome to TSG.

Try holding down the Windows key then pressing the P key, then select Duplicate. Does the projector work now ?
