How do I connect a PC to the TV using a VGA cable?

Connect the VGA output of the PC to the RGB (PC) jack on the TV using a D-sub 15 pin cable, and connect the PC audio output to the AUDIO (RGB/DVI) jack. Turn on the PC and the TV, then select the RGB-PC input source using the INPUT button on the remote control. For best picture quality, set the PC graphics card to 1360x768 (for 32/37/42LG710H, 32LD650H, 32LD655H) or 1920x1080 (for 37/42/47/55LD650H, 37/42LD655H).
