Does your desktop/PC display show anything before the monitor goes into power save mode? If nothing comes up, its possible that you have a loose VGA connection or that your video card/
motherboard are defective in some ways. Try using a different monitor.
If the other monitor works fine with your computer, try changing/lowering the screen resolution. If in XP right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution. If in Vista/
Win7,
right-click the desktop and select Screen Resolution/Display Settings
and adjust it there. Then check and see if your LG monitor works on
it.
If the other monitor also doesn't show any display, most likely the problem is either with your video cable or your PCs video card/motherboard, not the monitor.
Hope that helps. Good luck
