I next found out that my screen was a Samsung LTM201M1-L01 and after scouring eBay with this model number, I managed to find a display driver for this screen from eBay - just search for your screen model number

My LCD driver board has VGA, DVI and HDMI in and is powered by a 12V 4A external PSU - the eBay seller also sold PSUs, but I had one kicking about from another LCD screen.
