Monitor blinking on and off. I had this problem once before with this same monitor. When you went from the screensaver to the desktop it would flicker back and forth between the image and the black. After several minutes, the image would return and work fine. Then would repeat itself everytime the screensaver would reactivate. I checked my power settings and found that my power settings had changed to Turn the Monitor off after x minutes. So I changed that to never and it fixed it, the first time. A few month later it started doing it again, but it would never stay on an image, just constantly flash back and forth between the image and black. I recently hooked it up to a new computer and it still flashes and will not return to the normal display. The Blue power light flashes on and off as well. Worth fixing or just buy a new one? lol

Right click on your desktop and click properties like you would to change your screensaver.
Click on screensaver and then monitor power,
you will be able to change the preferences there

Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computer has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.

1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
   
2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
   
3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
   
4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."
   

check the desktop and display settings from the control panel,, then from there go to screensaver and power,, make all to never and make your screensaver also to none.. and see

chec your powersaving settings on windows if that's a monitor, to do this, just rightclick on the windows desktop and go to screensaver (you should know how to change the screensaver) there you click on "energy" and check the "automatically shutdown monitor time"

sounds like the monitor is going or the horizontal control isnt adjusted fully.

Is your screen saver kicking on every 1 min.?
On desktop... RIGHT click, choose Properties. Screensaver TAB.
You have screensaver and POWER (sleep options) you can choose.

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

• Video cable.
• Video adapter on PC (sometimes integrated on motherboard)
• Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Sounds like your screensaver is using a picture of your desktop in it's code intentionally.

Right click on a blank area of your desktop --> select properties

--> click screensaver --> change it to "none" or another screensaver

first turn hibernate off. this is probably causing problem with your screensaver. when you say your screen jumps that leads me to believe that your monitor is probably on its way out. If you can try to hook up a diffferent monitor and see if you have the same results

Try right clicking on the toolbar you can see, and you should get a list of available toolbars. The unchecked ones can be turned on, and you should get back to what you had.

If something is failing on your monitor which stretched the screen, shutdown the computer with the start button, and power off the monitor. Restart everything and see if that resolves the problem.
