External monitor plug in

Nov 22, 2018

It won't be a USB port but you have a D-sub which is a blue socket with fifteen holes to match a cable plug.

Also, check round the back for a port that looks a little like a USB port but has half-rounded ends. If you're lucky, it will be a HDMI port and ou could link the computer to a television set with the right cable and so long as the TV has HDMI ports.
