There are many problems with computer monitors, such as screens that flicker, pulsate or randomly dim.Over time, this can cause headaches and strain your eyes.The cause of monitor flicker is often caused by the wrong refresh rate, and in this case it only affects cathode ray tube monitors.A refresh rate that is too high can cause image distortions, while flicker can also be caused by other issues.Changing the refresh and resolution settings will often correct the flicker in Windows 8, as well as Windows Vista and Windows 7.
Step 1: Determine the refresh rate and native resolution.
Every monitor has a native resolution and optimal refresh rate, and the display will look best when the settings match these specifications.This information can be found on the box your monitor came in, the information that came with it, or online from the manufacturer.
Step 2: The Control Panel is where you should go.
The Control Panel can be found by pressing Windows key + X or going to the start button.Search for "resolution" from here or from the Control Panel, or locate Appearance and Personalization > adjust screen resolution.
Step 3: The resolution needs to be adjusted.
You can use the bar to match the resolution on your monitor.If you weren't able to find your monitor's native resolution, you can try the recommended settings.The common native resolutions are 800 x 600, 1920 x 1200, and 1680 x 1050.
Step 4: The refresh rate can be changed.
If you want to match the monitor's default refresh rate, go into Advanced Settings > Monitor tab.The advanced settings box will disappear when you click OK.Then click Apply.The refresh rate of the monitors tends to be less than the flicker rate.As you go with a higher resolution, you want to increase the refresh rate.
Step 5: You should update your drivers.
Problems with your display can be caused by outdated video and graphics drivers.Fix the refresh rate and resolution if it didn't help.You can find video and graphic updates for your computer or monitor by visiting the manufacturer's website.
Step 6: The default power settings should be restored.
The computer's power settings tell it when to turn off the display after a period of rest, and they also control the brightness based on certain factors.If you want to restore the default settings, go to Control Panel.You can save the changes.
Step 7: The power saving technology of Intel should be disabled.
The function that is available on certain computers is designed to reduce energy consumption.It can cause issues with the display, so turning it off may fix it.From the Start menu, select Search, and look for HD Graphics Control Panel.Click Apply, then OK, and then restart your computer.
