you should have a button that you have to press to get it to switch over, on mine i have to press and hold the Fn key then press the F4 key might not be the same on yours but you should have a f something key that has what looks like a little screen on it that is to switch the output if that does not work try hooking up your laptop just like before, and then restart it. good luck

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.

SOURCE: monitor says: no signal input check video cable .

Sounds a bit bland but either the monitor has failed or the video card

Only test is to plug your monitor into another system and see if it comes to life

If it does then your video card has expired.

If it is part of the motherboard then the easiest option is to buy a replacement which plugs into the AGP slot

They are dirt cheap unless you are into gaming when the sky's the limit

i have a 26" insignia lcd tv that i use as a montor uou musr set the screen resolution on your computer to 1024x768. if you use a higher resolution it will say no signal.so use your montor to set the resolution to 1024x768 then hook it to the vga and it should work. bob griggs
