What to do if my AOpen Nitro QG271 Monitor has no picture?
If your AOpen Monitor displays no picture, first, ensure the AC power cord is properly connected. Then, check the power switch and verify the video signal cable is securely connected at the back. Also, make sure your computer system is powered on. Finally, use the OSD to adjust brightness and contrast to the maximum or reset to the default settings.
Why is my AOpen Monitor showing an abnormal picture?
If your AOpen Monitor is showing an abnormal picture, ensure that the specifications of your graphics adapter and monitor are in compliance to prevent input signal frequency mismatch. If you are using non-standard signals, use the OSD to adjust RESOLUTION, CLOCK, CLOCK-PHASE, H-POSITION, and V-POSITION. If the full-screen image is missing, use the OSD to select another resolution or vertical refresh timing. After adjusting the image size, wait a few seconds before changing the signal cable or powering off the monitor.
