To connect your Lenovo L25E-40 monitor to your PC, use an HDMI or VGA cable. Connect one end to the corresponding port on your monitor and the other to your computer. Ensure both devices are powered on, and select the correct input source using the monitor's menu.
If your monitor is not displaying anything, check the cable connections to ensure they are secure. Make sure the monitor is powered on and set to the correct input source. If the issue persists, try connecting the monitor to another device to rule out hardware problems.
To adjust brightness and contrast, press the menu button on your monitor to access the on-screen display (OSD). Navigate to the 'Brightness' or 'Contrast' settings using the arrow buttons, and adjust them to your preference.
If the colors appear distorted, reset the color settings in the OSD menu to default. Ensure that the video cable is securely connected. You can also update or reinstall the graphics driver on your computer to resolve any software issues.
To clean the screen, turn off the monitor and unplug it. Use a soft, lint-free cloth slightly dampened with water or a screen cleaning solution. Gently wipe the screen, avoiding excessive pressure. Do not spray liquid directly on the screen.

If your monitor flickers, check the cable connections for any damage or looseness. Ensure that your graphics card drivers are up to date. You can also try adjusting the refresh rate in your display settings to see if it resolves the issue.
