Hi, I'm new here so sorry if I posted this in the wrong section.
My problem is this -
I've just bought a secondhand Samsung 46" LCD tv (model number LA46M81BDX/XSA) and connected it to my PC via a VGA cable. When I change the tv source to the PC channel it displays my extended desktop (the way I had it set up with the tv the Samsung replaced, a Toshiba 42" LCD) for approx 3 secs then seems to switch off ie. it clicks and the screen goes black. When I press the source button again it goes back to the av channel, but takes a couple of seconds to fire up, the same like it does when I turn the tv on.
I'm using a Dell Inspiron 550 Dual Core with a NVIDIA GeForce 210 grahpics card and running Windows 7 Home Premium x64. If you need more system details I'll happily supply them.
Thanx in advance for any help.
