I have just come home with my impressive new Samsung set (mainly on recommendations found on these very forums, thanks!), and am very happy with the quality! I am having some trouble connecting my PC to it however. My PC has a DVI output, so in absence of the correct cable (have just ordered a HD - DVI cable this evening) i tried to connect using a DVI-VGA converter and a VGA cable plugged into the PC input of the TV itself. Not only do i not get a picture (the TV goes into standby mode), but the option for PC is greyed out and unavailable in the TV's connection menu. Is this normal? Does the PC option only become active when it detects a valid PC signal? will my new cable fix this? sorry for all the questions! thanks!!
