I connect through the VGA port, via a Raritan four port KVM to a VGA screen.

I do not use HDMI.

I have just come home and pressed the space button on the computer and the screen is working. It was not working when I left to go to work this morning.

I wonder if it's due to a screen saver kicking in and making it work (or something). I've just changed the energy saver to one minute, will restart and see what happens.

This is weird.
