Your right. I just had the same "Invalid Input" issue as well and it completely relates to the resolution compatability with any VGA or HDMI connection. Check the LG website for the online manual if you don't have it and see the section on RGB-PC cable. There is a table that incdicates the Resolutions the LG product is capable of displaying.
Thanks for the help.

Most tvs can only handle a couple resolutions (ie 640x480) through the pc input. Even some HD tvs can only do 480. Check that your video is turned on and setup to the acceptable resolutions.
right click your desktop
go to properties
click settings tab
click on the 2nd monitor
make sure the box is clicked at the bottom

(1) Have you selected VGA Output on the Laptop?
Usually there is a Function Key combination like Fn Plus F7 to send output to the external VGA Port, usually depicted by a monitor icon on the F7 Key
(2) If still no input to the TV, check the TV manual for the frequency of the VGA Input.
For Windows XP Sometimes you have to go into
Control Panel / Display / Settings /Advanced then Monitor Tab
& look at the Screen Refresh Rate.
Suggest you try lowering that value till it produces a signal.

Set the screen resolution, on the PC, to a low initial setting say 800x600 32bit, and also ensure your Video Out is set right either PAL or NTSC depending on what your TV receives. Make sure you have activated dual display "Extend windows desktop to here" under Video Properties, (Right Click Desktop)...and finally plug in to TV, turn on, and THEN boot up.
