Monitor Flickering

Postby Global Citizen » Sun, 22 Jan 2006 12:11 am

Lately I've noticed that my monitor flickers quite a bit. Can anyone pls tell me why this is happening and what can I do if anything to stop it?

Thanks in advance for your help.

Try the following to fix:

1) At your desktop, right click your mouse and select Properties
2) When the Display Properties window comes up, click on the Settings tab at the top right.
3) Then click the Advanced button at the lower right.
4) Click on the Monitor tab at the top.
5) Check the Screen Refresh Rate....it should be around 75 Hz to avoid flicker.

If your refresh rate is lower (like 60 Hz) then try setting it to 75 or 80. However, just to be on the safe side, make sure your monitor can handle the higher refresh rate first!! Google it to look up your monitor model number and check its capabilities. Once you know that it will handle 80 Hz (most CRT monitors will anyway, mine goes to 100 Hz, but I'm just being extra cautious :o ) then go ahead with the above steps.

Btw...noticeable flicker is due to low refresh rates. The electron beam at the back of your monitor is constantly "painting" an image top to bottom on your screen at an extremely fast pace. However, 60 Hz is dang quick, but not quick enough since the human eye can sense the "refreshing" of the lines on the screen. When you raise the refresh rate, it's fast enough that our eyes can no longer sense any flicker. The screen looks more stable and is certainly easier on the eyes :)

A couple of questions:

* Is your monitor CRT or LCD?

* How old is your monitor?

If it's a CRT monitor that's reasonably old (>5 years), and it's only just suddenly and randomly started flickering (and the suggestions from Genesis don't work), it could be that the tube (or the guns) is about to fail. Try taking it to a computer technician.

Thank you both for your suggestions.

I checked my refresh rate as Genesis said and found it set at 75hz and the only other option offered was 60hz so I went down to try it. There seems to be some improvement at this time but I'm watching it.

I have a NEC MultiSync LCD 1525V Monitor and have had it for a few years. I'll keep monitoring the screen for now and keep my fingers crossed.

If you have had it for several years that might mean it is on its 'last legs'.
Will try to find out something about the life expectancy of LCD screens and get back to you.

I am on my fourth monitor now. Can't remember my first one. Second one cathode lasted 3-4 years and flickered and hubbyy (computer geek) said it was time to retire. 3rd one was 17-inch Princeton LCD hand-me-down from hubby used for total of 4 years when resolution became not-so-sharp (no major problem) anymore. Hubby just got me a 19 inch Viewsonic LCD and we'll see how that last. Think most monitors work fine for about four years before diminishing return sets in.

I find it important for my monitor to be in optimum shape so as not to cause eye strain or worse, ruin my eyesight.
