19 1/2 inch monitor (measured diagonally).
This is not top of the range but it looks usable. I couldn't test it properly as I don't have the right cable.
See picture, this takes a DisplayPort type cable or the old style VGA.
*Cables not supplied*, you will need a connector to connect the monitor to your computer, and you will also need a mains cable as I don't have one available.
