To adjust the screen resolution, right-click on your desktop, select 'Display settings', and choose 'Resolution'. Select the recommended resolution for the best display performance.
Ensure that the power cable is securely connected to both the monitor and the power outlet. Check if the power button on the monitor is pressed. If the issue persists, try using a different power cable or outlet.
Connect one end of the HDMI or DisplayPort cable to the monitor and the other end to your PC's corresponding port. Make sure the monitor is set to the correct input source using the monitor's on-screen display menu.
Check if the video cable is properly connected to both the monitor and the computer. Ensure the monitor is on the correct input source. Restart your computer, and if the problem continues, try using a different cable or port.
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 without applying too much pressure. Avoid using paper towels or rough materials.
For optimal gaming performance, adjust the refresh rate to the highest setting supported by your monitor and graphics card. Enable any gaming features like Adaptive-Sync or Overdrive to reduce lag and motion blur.
Firmware updates for monitors are rare and typically unnecessary. Check Acer's official website for any available updates and follow their instructions, if applicable.
Adjust the color settings in the monitor's on-screen display menu. You can also use color calibration tools available in your operating system or third-party software to achieve more accurate color representation.
Use the monitor's blue light filter or low blue light mode to reduce eye strain. Adjust the brightness and contrast settings to comfortable levels, and take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
Try using pixel repair software that rapidly changes colors on the affected area to possibly revive stuck pixels. If dead pixels persist, check Acer's warranty policy for possible repair or replacement options.
