I have a Lenovo T500 running Windows 7 and am trying to use a VGA cable to connect it to my Sony Bravia KDL-46VL150 HDTV. For whatever reason, the TV has "PC" greyed out as an input option. I've tried switching on the projector mode on the laptop (Fn - F7 key combo), as well as on the Desktop (right click, choose "Screen Resolution", and then choose "Connect to projector").
None of these make the "PC" option active under the TV's input choices. I've tested the PC at work, connecting it to an HDTV using a VGA cable, and it works. What am I doing wrong with the Sony TV? Thanks.
