Question about Computers & Internet
As per your description the monitor is disconnected from the computer and then reconnected. That is why the message pops up. To troubleshoot you may have to open the PC cover and investigate but we will leave it as a last resort.
To begin,you must disconnect the PC and monitor from the power source.
First look at the back panel of the LCD and check the connection of the VGA cable. There are two screws which you can turn by hand or a flat screw driver. Loosen them and remove the jack. Do the same with the other end connected to the PC's VGA out.
If you have a can of compressed air or a blower use it to remove dust off the jacks and replug them making sure the screws are tight but not too tight or you will damage the connector. Just tighten them by hand.
Now see if the problem is gone or not.
The next step would be to re-seat the video card if you are using a PCI or AGP card. If its an onboard VGA then skip this step. You must take caution or you will end up with a non working PC. If you are not comfortable doing this ask a friend or take it to a computer shop. But its not that difficult. Try to do it with a frind's help to save cash.
If the issue persist which is unlikely then try a new cable. You LCD also has a jack for DVI-D input:
You can also use a DVI-D or VGA to DVI-D cable if you r video card supports. Refer to the quick start guide or manual on how to perform connections.
