The amount of flicker when the screen is turned on depends on the settings for the refresh rate of the monitor image. The concept of "refresh rate" is applicable to lamp monitors, these settings are not important for liquid crystal monitors. The screen of most lamp monitors is refreshed once a minute. If these settings are not suitable for you, take a few steps to fix the screen flickering.
Instructions
Step 1
Call the "Display" component. To do this, open the Control Panel through the Start menu. In the category "Design and Themes" click on the "Screen" icon with the left mouse button or select any of the available tasks at the top of the window. If the "Control Panel" on your computer has a classic look, select the desired icon right away.
Step 2
There is another way: right-click in any part of the "Desktop" free of files and folders. In the drop-down menu, select the "Properties" item by clicking on it with the left mouse button. A new "Display Properties" dialog box will open.
Step 3
In the window that opens, go to the "Options" tab and click on the "Advanced" button located at the bottom of the window. This action will bring up an additional dialog box "Properties: Monitor Connector Module and [name of your video card]".
Step 4
In a new window, go to the "Monitor" tab and place a marker in the field opposite the inscription "Hide modes that the monitor cannot use." This will help you avoid potential problems: if the screen refresh rate is set incorrectly, the image on the monitor may be unstable. Also, an incorrectly selected frequency can lead to equipment malfunction.
Step 5
Using the drop-down list in the "Monitor settings" section, set the required value in the "Screen refresh rate" field. The higher the refresh rate of the screen, the less the monitor flickers. The default is 100Hz, although your monitor may support other frequencies. Check this information in the documentation or on the manufacturer's website.
Step 6
After making the necessary changes, click on the "Apply" button in the monitor properties window. Answer in the affirmative when asked to confirm the new parameters. Click on the OK button. You will be left with one window "Properties: Display". Close it using the OK button or the [x] icon in the upper right corner of the window.
Step 7
If the look of the desktop changes when you change the refresh rate, set the display resolution to a readable resolution in the screen properties window, click the "Apply" button and close the window. Adjust the size of the working area on the screen using the adjustment buttons on the monitor body. Don't forget to click on the Degauss button at the end.
