To adjust the screen resolution, right-click on your desktop and select 'Display settings'. Under 'Resolution', choose the desired resolution that matches the monitor's native resolution, which is 2560 x 1440. Click 'Apply' to confirm changes.
First, ensure that both the power cable and video cable are securely connected. Check if the monitor's power indicator is on. If not, try a different power outlet or cable. If the issue persists, test with another device or replace the video cable.
Utilize the 'Blue Light Shield' feature found in the monitor's on-screen display menu to reduce blue light emission. Adjust the brightness and contrast settings to comfortable levels and take regular breaks following the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
Currently, Acer does not provide a direct method for end users to update the monitor firmware. Ensure that your operating system and graphics drivers are up to date to maintain compatibility and performance.
Check that the video cable is firmly connected to both the monitor and the computer. Ensure the correct input source is selected in the monitor's on-screen display menu. Test with another video cable or port if available.
Turn off and unplug the monitor. Use a soft, dry microfiber cloth to gently wipe the screen. For stubborn spots, lightly dampen the cloth with water or a screen cleaner. Avoid using paper towels, rough materials, or harsh chemicals.
Yes, the Acer EB321HQUD is VESA mount compatible with a 100mm x 100mm pattern. Ensure you use a compatible wall mount bracket that can support the monitor's weight and follow the installation instructions provided with the mount.
Access the on-screen display menu, navigate to the 'PiP/PbP' settings, and select 'PiP mode'. Adjust the position and size of the PiP window as needed. Ensure that the secondary input source is connected to the monitor.
Use a hardware calibration tool, such as a colorimeter, for the most accurate results. Alternatively, utilize the monitor's 'Color' settings in the on-screen display menu to adjust brightness, contrast, and color temperature to your preference or according to the sRGB standard.
Ensure that the video cable is secure and try a different cable if possible. Update your graphics drivers to the latest version. Check the refresh rate settings in your operating system to ensure they match the monitor's specifications. If flickering persists, test the monitor with another device to rule out the graphics card or settings as the cause.
