How to Correct a Blurry Screen

There is nothing worse than a blurry screen when you are trying to work or play on your computer. There are a few common causes for a blurry screen, and most causes have fairly simple fixes that can be done without the expensive help of a trained technician.

Here are a few of the common reasons for a blurry screen and some ways to troubleshoot through each of them.

• Extreme hot and cold temperatures and changes between the two can cause the computer screen to become blurry. Ensure that the location of your computer has a fairly regulated temperature. If your screen is only occasionally blurry, take note of the temperature at the time when you notice the blurry screen. Even fans and overhead lights can contribute to a blurry screen. Experiment by removing fans and turning off lights to see if it eliminates the problem with your blurry screen.
• Magnetic devices around your computer system may cause issues with your monitor. Remove magnets or toys away from the screen to see if this helps the resolution.
• Loose monitor connections are a common cause for monitor blurriness. Believe it or not some people forget about the most obvious culprit. Check your connections; ensure that both ends are secured tightly.
• The picture may be out of alignment. It is easy for resolution settings to get adjusted by mistake. Play around with the controls on the monitor to see if this brings the picture back into focus.

If none of these tips help to resolve the issue of your blurry screen it may simply mean that your monitor needs to be replaced. If possible, try hooking up another monitor to the same system to see if the problem persists before purchasing a new monitor.

No Signal Message

Nothing can be more frustrating than turning on your computer and then being faced with the No Signal message being displayed on your monitor, particularly if your computer has started fine and appears to be running (fans whirring, lights on, etc.). Of course, to make matters that little bit more annoying, you can’t see what your computer is doing.

The No Signal message literally means that your monitor is not getting a signal from your computer, but it does have power. There are many different reasons why this could be happening, so the solution will depend on what the actual cause is.

Check the Cable

Before doing anything else, you should make sure that the problem is not due to the cable connecting your monitor and computer. First, you should ensure that the cable is plugged in properly to both the monitor and the computer. Also, ensure that it has not been damaged in anyway. If the cable appears fine, yet you are still faced with the No Signal message, you may want to try another cable just to be sure. If possible, use a cable that you know works. If you are still faced with the No Signal message, then the next cause to check is the monitor itself.

Faulty Monitor

Often, if there is a problem with the monitor, not only does the No Signal message appear on its screen, but most computers also beep on start up when the monitor should be connecting. To determine whether it is your monitor, try plugging the suspect monitor into another computer. Also, you can try plugging a different monitor into your computer. If the monitor doesn’t work when plugged into another computer, then it is likely that you need to have something repaired. If you try a number of different monitors and none of them work, then there is a problem with your computer.

Update Drivers

If you have one monitor work but not another, it could be down to the fact that you have an out of date or faulty driver. Use the Device Manager in Windows to update and fix any drivers. Once you have checked your drivers, try plugging the monitor in to see if it now works.

Graphic Card Issues

Sometimes a faulty graphic card can interfere with how a monitor works. Again, you can check the drivers for a graphic card using Device Manager. Also, you can test the graphic card compatibility by taking out one card and putting in another. If you feel uncomfortable doing this, take your computer to a repair technician so that you don’t cause any further damage.
