Make sure you do not have your speakers close to the monitor as the magnets can cause this problem ,also power boards will do the same thing.

if these are not the problem, it maybe that the monitor is on its way out.

good luck

My screen keeps flickering and its only two weeks old


Step 1 Change the refresh rate to match the capabilities of your monitor. The refresh rate is a measurement of how many times the screen redraws each second. Although this setting is related to older, desktop monitors, it can affect the quality of the Liquid Crystal Displays found in laptops. Right-click the desktop and choose "Screen Resolution," then click "Advanced Settings" and "Monitor." If enabled, place a check beside "Hide Modes That This Monitor Cannot Display" and choose a higher refresh rate from the list.
Step 2
Update your graphics card drivers. This is the most likely cause if you've always had a problem with flicker. Look for "Hardware and Sound" in the Control Panel and click "Device Manager." Under "Display Adapters," you'll see the exact brand and model of your video card. Go to the manufacturer's driver Web page and search for this model to download the appropriate drivers. Alternatively, you can revert to an older driver if the flicker began immediately after an update. In this case, return to the Device Manager, right-click your adapter and then "Driver." Click "Roll Back Driver" and "Yes" to confirm.
Step 3 Turn on Vertical Sync if the flicker occurs when DirectX or OpenGL is in use, for example, while playing a PC game. Vertical Sync, or VSync, locks the refresh rate of the application to the refresh rate of the monitor. Horizontal flicker is reduced, which improves image quality. For Nvidia cards, VSync is found in "Manage 3D Settings." For Intel, look for "3D Settings" or "Asynchronous Flip." On ATI/AMD cards, turn on "Wait for Vertical Refresh."
Step 4
Lower and raise the laptop screen repeatedly to determine if the flicker is related to movement. Hardware failure is the likely cause when flicker occurs only when the laptop moves. Most likely, the screen cable is loose or damaged, but the inverter and backlight can also cause this problem. The laptop needs to be opened in order to confirm the problem, but do not attempt this unless you are familiar with PC repair and do not mind voiding the warranty. For the best results, take the laptop to a licensed technician or send it back to the manufacturer.

Screen crashed to flickering gray screen


Try a roll back of the Graphics driver. Have you done any Graphic Updates? Install the driver from the DELL or Windows Update website. Does it work with a external monitor? When you boot in safe mode your machine uses the Basis graphics driver. Is the monitor OK when you boot in safe mode?

My monitor is flickering


Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software monitor may flicker and goes into rolling state due to dust, overheating after a long continuous usage,loose circuitry or due to some electromagnetic interference with other like tv , UPS, large speaker systems etc.


FIX :

1.Try Re-installing your Video driver

2 If it is possible, connect a different monitor to the computer. If the flickering disappears, it is a fair indication that the monitor is defective, otherwise go to the next step.

3. Set up the computer and the monitor on a different place in your house. If the flickering disappears now, it is most likely an interference caused by something in the original location. Check for devices which can cause interference.

4. If the flickering persists, check the setup of your system. If available in the setup, make sure that the option Monitor Type is configured as Colour Non-Interlaced.


If you don't think any above possible reasons for the rolling or flickering state of your monitor then we recommend you to get your monitor checked by the monitor company at their respective service cente

Monitor flickers with lines across screen


screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

Toshiba Satellite M300 screen problem


Hi, I can't guaranty this will help the problem, but for a quick try I say its worth it. On the Desktop, right click to open Personalize, select Display Settings; by adjusting the resolution it helps with the "Flicker effect" aswell, by selecting different settings, you can "view" the best Monitor Display. "If the solution helped, rating it is appreciated, thanks."

Monitor flickering and rolling


Thanks for the git back: #1 I hooked up a second monitor (depressed fn+f5) and was able to view everything fine. No problem in any area. Ran Some security checks (malwarebytes,checked windows updates,Secunia PSI,and a virus scan. #2 I opened up the monitor and checked for possible loose connections. #3 brought up the graphics display and checked that 60 hrz was set and correct. #4 ran a backup of all my data from my other monitor,and I made the assumption that it was a bad monitor and I might save some money if I just bought a new laptop.Would like to here your comments. Sincerely : dandee4u3

Screen rolls


Hi,
I'm writing to you on a screen that is rolling and sometimes flickering right now. I've tried 3 different screens on the same outlet, and they all have the same problem.

1. If you have any speakers near your monitor, try moving them away, this might help because they might not be shielded enough.

2. Try another screen, if the problem persists, it may be your power outlet.

3. If you don't want to spend money on a new screen, spend some time looking for a 3-prong grounding adapter.

I used the 3-prong grounding adapter, those little adapters that plug into the wall using 2 prongs, and then you can plug a 3 prong appliance into them on the other site, and it helped make the rolls not appear as often, and not as dark.

I think it is something with my power or the plug I am using.

Hope this may have helped a tiny bit
