Hello, new to the site. I have an older HP Pavilion commuter and recently obtained a Mac hd display 23inch screen and want to connect to pc if possible? Pc has an Nvidia GeForce 2 mx 400 graphic card with a VGA output. Tried an adapter but nothing happened. Seems that I need a different card with a DVI output but not too sure which one would be compatible with the pc. Any help appreciated. Thanks. Oh don't confuse me with too much technical jargon.
