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.

Do not keep forcing this unit on - - This particular unit has a VERY commonly known problem and there are at least five tech bulletins from LG explaining this and other symptoms for the failure. In a nutshell there are coils that have to be removed and replaced with a jumper wire. This is not a repair you want to tackle so please get some experienced help for this one. A good technician will look-up the bulletins and educate themselves on the manner of the repair.
Almost all of the symptoms that can happen are intermittent and can be extremely difficult to verify. For this reason make sure to discuss with the technician that he replace all of the coils listed in the bulletin not just the ones causing your particular problem. Here's a list of symptoms that these defective coils cause, taken right from the bulletin:
1. Channels Or Menu Functions Scroll On Their Own
2. Remote Does Not Function
3. Tv Randomly Powers On And Off On Its Own
5. No Backlight
Hope this helps!
