Hi I've just purchased the mentioned lcd, but am having poroblems with the vga connection when I'm hooking up my pc. I plug it in and when I boot the pc up the screen flashes and then brings up the boot-up screen the computer puts out, but the when its supposed to display the welcome screen the tv constantley flashs blank with the TV's input flashing with it aswell (named PC). I hope that made sense! Have I a faulty set or am I doing something wrong? any help will be much appreciated. regards.
