ASUS PQ321QE User Manual

To connect the ASUS PQ321QE monitor to your computer, use a DisplayPort cable. Ensure that your computer's graphics card supports DisplayPort 1.2 for optimal performance. Connect one end of the cable to the DisplayPort on the monitor and the other to your computer's DisplayPort output.
First, ensure that the power cable is securely connected to both the monitor and a working power outlet. Check if the power indicator light is on. If the monitor still does not turn on, try using a different power cable or outlet. If none of these steps work, the monitor may require servicing.
To adjust the screen resolution, go to your computer's display settings. On Windows, right-click the desktop and select 'Display settings'. On macOS, go to 'System Preferences' > 'Displays'. Set the resolution to 3840x2160 for optimal display quality.
Display flickering can be caused by a loose cable connection or incorrect refresh rate settings. Ensure all cables are securely connected. Check and adjust the refresh rate to 60Hz in your computer's display settings. If the issue persists, consider updating your graphics drivers.
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 in a circular motion. Avoid applying excessive pressure or using abrasive materials.
For optimal color settings, access the monitor's on-screen display menu. Navigate to the 'Color' settings and adjust the brightness, contrast, and color temperature according to your preference. You can also use the 'sRGB' mode for standard color accuracy.
To enable PiP mode, access the monitor's on-screen display menu. Navigate to the 'Input' section and select 'Picture-in-Picture'. Choose the input source for the secondary display. Adjust the position and size of the PiP window as desired.
Dead pixels can sometimes be fixed by applying gentle pressure with a soft cloth or using software solutions that rapidly change colors to stimulate the pixel. If the issue persists, contact ASUS support for further assistance.
To update the firmware, check the ASUS support website for the latest firmware version for your model. Follow the provided instructions for downloading and installing the update, ensuring your monitor is properly connected during the process.
Ensure the monitor is set to 'sRGB' mode for accurate colors. Check your graphics card settings to ensure no color adjustments are applied. If you're still experiencing issues, calibrate the display using a color calibration tool for precise color accuracy.
