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

Mine has the buzzing. I even created this current one out of 2 damaged ones, the original internals did it as do the internals I took out the "new" one I got (it had a smashed screen). I noticed it stops completely when muted, but not when the volume is on 0. It also gets louder when the contrast is higher (just flick between the preset PICTURE MODE's). I think it's something to do with the internal speaker cables perhaps running too close to the display circuit or whatever (Im not sure what causes it, its normally electrical interferance being picked up by an unshielded cable). I'll no doubt get hacked off and reopen it soon to look about. I'll post back when I do, may be a few months though!
