Flicker/Refresh rate on Acer LCD

When looking at the monitor it looks as though a screen would look if you were looking through a video camera or something of that nature. A series of horizontal lines moving from the bottom of the screen toward the top. The lines themselves are really just a shade or so off from the natural display color of whatever is on the screen. We can still see the picture, but it is annoying as hell. We've tried updating the drivers, using different cables, and even hooking the lcd monitor up to a different pc. The problem seems to be in the monitor somewhere. Does anyone know what might be causing this and how I can repair it?

    OK. So my monitor was working fine for at least 3 months. Then I got this too. Just turned on my screen one day and had horizontal lines that span the width of the screen and scroll along with the image. It's like whatever image is on the monitor bleeds across the screen. Like at night when you see light spread horizontally from a street light. I hope this helps explain the problem. Any help would be awesome. Thanks.

I had this problem and when you turned it off a while and turned it back on it was fine a while then went back to the "scrolling" lines.
come to find out it was my "onboard graphics chip getting to hot to run my 1024 resolution.So I went to China-mart er... I mean wal-mart and got another graphics card and upgraded that and voila,no more rolling bars across the screen.I guess I could have possibly reduced the resolution but I liked the way it was. :-D

My monitor compaq model MV520 is always blinking every time I open my computer, How can I fix it?.


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to answer and solve your problem. Your Compaq MV520 Monitor is always blinking every time you turn on your computer and you want to know how you can fix it? First, we need to troubleshoot the problem. I'm thinking you probably need to refresh the flicker rate on your monitor. The flicker rate is probably set on a low setting, which is causing you screen to blink (flicker). This can be bad for your health as well because it can cause eyestrain and headaches. Your monitor is a CRT (Cathode-Ray Tube) model. These types of monitors can cause a lot of screen flickering. Now that we've troubleshooted the problem, now it's time to solve the problem. There are two ways you can solve this problem. You can either refresh the flicker rate or you can buy an LCD monitor. LCD monitors flicker-free. My suggestion is that you refresh the screen flicker rate. To refresh the flicker rate, go into your System Preferences or Control Panel, click your operating system's appearance and display link and click your screen adjustment link. You may have to click your advanced settings link. Click your monitor tab and from there adjust you screen refresh rate. You may have to adjust your screen resolution before you refresh the screen rate. If you have to do this, make sure the screen resolution you choose supports you monitor's height and width as well as visibility. The higher the resolution, the higher the screen rate. The instructions I'm giving you may sound like this because I'm not sure what your operating system is. I'm not to familiar with Mac Operating Systems, but if you have a Windows Operating System and you need better detailed instructions, just reply back. I hope this decreases your screen flickering and gives you a better viewing experience.

How to get rid of screen interference


Have you ever had a wired interference on your screen:
alonmln.jpg
NOW IT ENDS!
There are couples of easy steps that will solve your problem!
1. Look out for any Electromagnetic field emitting devices next to your
monitor and move themaway(like phones, big magnets, speakers...)
2.Make sure that the monitor's plug, is well plugged and notmoving around.
3. On some systems, it is possible to reset therefresh rate of the monitor to line frequency (60 Hz) without serious sideeffects. More often, though, this will result in a sacrifice of resolution, andin almost all cases, the jitter will have been traded for flicker (the refreshrate has been increased by the monitor manufacturer to avoid flicker - the eyecan detect a refresh of the image at 60 Hz). Further, if the backgroundmagnetic fields are strong enough, even setting the refresh rate to 60 Hz willnot remove all of the jitter.
4. If all above doesn't work, and you can't stand the interference simply buyand LCD screen and never have these kind of trouble again.

Flickering LCD/CRT monitor screen or unstable image fix


If the screen flickers, make sure the display settings in Windows match the native resolution and refresh rate for the monitor. You can find the native resolution of a flat panel display in the specifications, in the printed material or on the box that came with the monitor. Some common native resolutions are 800 x 600, 1024 x 768, 1920 x 1080, and 1680 x 1050. To find out more about optimal screen resolutions see my tip on resolutions here.

The most common refresh rate for LCD monitors is 60 Hz. This normally cannot be changed for flat panel displays using Plug and Play settings. However, if you are using special video software to increase or decrease the refresh rate, change the refresh rate to match the default refresh rate specification of the monitor. To find out more about refresh rates see my tip here.

STEP 1
To change the screen resolution and refresh rate settings in Windows, do the following:
- In Windows XP
See my tip on setting up the optimum screen resolution for Windows XP here.

- In Windows Vista
1. Click Start, and then click Control Panel .
2. Find the Appearance and Personalization area, and click Adjust Screen Resolution .
3. Move the slider bar until the screen resolution matches the native resolution.
4. Click Advanced settings, and then click the Monitor tab.
5. Select the Screen refresh rate that matches the default rate for your monitor (if it is not already selected).
6. Click OK, and then click OK again.

If you cannot select the native resolution or the native resolution is unavailable, continue to the next step to update the drivers for the graphics adapter on the computer.

You can get the latest updated video drivers from the video hardware manufacturer's Web site. Here is a list showing some of the video hardware websites:

Check for NVIDIA video driver updates at NVIDIA Home Page.
Check for ATI/AMD video driver updates at ATI Home Page.
Check for Intel video support and downloads, Intel Downloads.

After updating the video drivers, go back to Step 1 and try to change the screen resolution again.
Note: If you cannot select the native resolution after updating the video drivers, the graphics adapter in the computer might not support that resolution and may need to be upgraded.

If after changing the resolution and updating video drivers the flickering persists then check the video cable connections. Unplug the cable and inspect the cable for damage. If the cable is damaged, replace it with a new cable. Try to use cables less than 3 meters (10 feet) long.

Monitors are sensitive to magnetic fields so have a look at the environment around the monitor. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause flickering. Temporarily move electrical items away from the monitor to see if they is producing a field that causes the flicker.

If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.

To see if the video coming from the computer is causing the problem, temporarily connect the monitor to another computer. If the flicker is gone when the monitor is connected to another computer, the graphics adapter hardware on the first computer might need to be upgraded to use the monitor.

If however the flicker remains then the problem lies within the harware of the monitor itself and is not a software problem. If you have bought this monitor fairly recently then I suggest you take it back to the place of purchace and have them test it. Some monitors carry 3 year warranty support so if you bought it within the warranty period specified by the reseller I suggest you see if you can get refunded or have them swop it out.

Monitor flikkering .i will check the VGA cable and power cable both are properly connected but the monitor is flikkering .what i do



Answer Sometimes if the refresh rate isnt set high enough you will see a noticeable flicker on the screen .. to change the monitor refresh rate .. you can right click on the desktop and then left click on properties .. click on the setting tab then click on the advanced tab then click on the monitor tab ..look in the drop down menu where it says 60 hertz and see if the refresh rate can be changed .. if it cant .. uncheck hide modes the monitor cant see and then click on the drop down menu .. pick a refresh rate .. 75 hertz is what i use and it should stop the flicker


Answer
keep electronics away from your computer. Mobie phones etc. can distort the image shown on the screen for periods of time, usually when a text or call is coming through.

Answer
A nearby device can cause stray magnetic fields that will cause the display to be affected.
A problem inside the monitor will cause the display to have problems.
If somebody turns on their monitor nearby, the monitor's degaussing when it starts up will cause your monitor to dance wildly for a moment or two.

Answer well one major cause can be the weakness of the electron gun that fire electrons on the silicon plate (pixels) that produces image on the screen so there must be some problem in electron gun in my view

My Acer Aspire one screen flicker, I am running windows xp with 1 GB ram, I try to connect a external lcd monitor, the monitor display do not flicker. It seems that if I don't use full screen, the flicker...


Please check the refresh rate of the display. If it is more than 60Mhz, it could cause your LCD to flicker.

Go to your display options and adjust the refresh rate.

If that does not fix it, it could be a possible problem with video card.

Try updating the driver software for the integrated video card.

Good Luck Kumpadre!

I can not go past 1152 by 864 resolution, the screen will turn off and flicker also now it looks like video shown on the monitor is very high in contrast and sometimes the monitor will be on but no picture...


This means that you have reached the limitation of the graphics card of the PC that you have connected to it. You could try changing the Refresh rate of the card to see if you can get a higher resolution.

Screen flickers for about 20-30 seconds sporadically


Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

Moniter flicker


Any monitor flickers at 60 hertz. The usual reason for being unable to use faster refresh frequencies is that the correct video card driver and/or monitor driver are not installed. Another possibility is that the resolution is set too high. Assuming Windows XP, right click on the background, choose "properties", settings tab, advanced button. Check to make sure your video card is named - the monitor is not as important but would certainly be helpful. If not, did out the CD's that came with them or download drivers from the manufacturer's website. On the other possibility, on the adapter tab, there ought to be a "list all modes" button so you can choose resolution and refresh rate at the same time. Your LCD monitor will be fussy about the resolution, so you may need several tries to get something that looks good and doesn't flicker.
