LG Flatron Monitor flashes on and off intermittently when used with PC

It may be the mouse. Try a different mouse.

Click on: Control Panel, then click on Hardware & Sound, then click: Change When Computer Sleeps, then select the time setting you require in:"Turn Off The Display."

Sounds like an issue with you PC not the monitor.

Try updating your display/graphics card drivers.

Replace the mouse with a new optical mouse.

1. In order to fix this, you go to control panel > mouse
the last tab is called "Device Settings" click it and make sure you have "static tray icon in taskbar" selected.
(You can always remove this later.) Apply the changes and click the red coloured icon in your task bar. An option will be available called "Tap to click." Clicking it will enable you to tap with your mouse pad instead of the keys! Hope this helps you out, I know it helped my friend.

2.
In the Control Panel open Accessibility Options Icon and click Mouse Tab and than Setting.

In windows xp go into start menu, then into control panel then click on appearance and themes, then move your mouse over to mouse pointers click on it , uncheck "enhance pointer precision, and click apply, that will stop the mouse from acting crazy, this will work with dell mouse pointers and most.

Sounds like an issue with a memory card or pci card not properly in place. Try opening up the sytem, then make sure each card is properly inputted in it's slot. This may cause the the monitor to show power saving mode especially if the memory is not properly placed.
Thanks
