Get this flsh out of my monitor.

Hi there.

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.

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 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 (Same for Windows 7)
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/AMD Home Page.
Check for Intel video support and downloads, Intel Downloads. (If you have an Intel mainboard and are using onboard graphics).

NOTE: If you are using onboard graphics with a mainboard that is not manufactured by Intel, just give me the name and model number of your mainboard and I can try and locate the graphics drivers for you.

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, then this means that the graphics adapter hardware on the first computer is damaged or might need to be upgraded to use the monitor. On the bright side at least it's not your monitor.

If however the flicker remains then the problem lies within the hardware 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 purchase 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.

Your monitor supports a maximum resolution of 1280 x 1024. If windows fails to give you the option of changing to this resolution and those below it then please follow these suggestions:

Update your video card drivers, if you don't know the manufacturer of your video card try windows update.

Install the latest drivers for your monitor as well.

Try changing the refresh rate, you could be getting flickering from your lights if the refresh rate is close to 50Hz.

I assume it is an LCD monitor, sounds like you have bad lamp or a lamp power supply. It also could be wrong refresh rate for the monitor, try changing the refresh rate on your computer.

Picture on monitor is distorted

I went to the panel buttons, and then punched the reset for each of the icons on the menu. That restored the display picture to its factory settings. The degaussing did not help the picture, and any stray magnetism is generally automatically degaussed when the computer starts up. As to the flickering of the picture, that is because of the refresh rate. I am using a relatively updated operating system, and the refresh rate has changed somewhat. I also believe the temperature of the computer affects the flickering. I hope this comment helps someone who has a similar problem.

Best regards,
