Flickering screen

This is a great site.

Try changing the refresh rate for your monitor. A lot of video cards give you the option to select the refresh rate and they are mostly found under the 'Advanced' button in the 'Settings' area of 'Display Properties'. Many older video cards do give you the option of changing the refresh rate (especially if you are using the Microsoft supplied driver). Third party software like 'Display Doctor' may help you out in that case.

Monitor flicker can be caused by a number of things.

A nearby power line can cause flicker.

As can having the wrong refresh rate set.

Make sure that the drivers for the video card are properly installed, and that your monitor is correctly identified in Display Properties / Settings / Advanced.

If the flicker just started recently, or is getting worse, it may be a sign that the monitor is starting to fail.

You might check to see if your monitor cord is attached firmly to your puter, and then degauss.

I am glad I finally decided to do something about it. After asking the question, I read alot of the answers on this subject, and prayed my problem was not a major one...The flickering was quite annoying on my DELL Inspiron 1470. Now, it's fixed ! I reckon due to jus play with the electrical connection...and move the screen a bit. Turning it on this morning, the flickering was back, and I just had to do the same things I did before. And as a matter of fact, I've just moved the screen to leave it in any position I wanted, and that annoying flickering is no more ! So, maybe you should just try the same trick before you send it away...Good luck !
