  If your Acer monitor displays no picture, there are several things you can check. First, use the OSD to adjust the brightness and contrast to the maximum or reset them to their default settings. Ensure the power switch is on and the AC power cord is properly connected to the monitor. Verify that the video signal cable is securely connected to the back of the monitor. Also, make sure that your computer system is powered on.

Why does my Acer Monitor have an abnormal picture?

  An abnormal picture on your Acer monitor might be due to a mismatch between the graphics adapter and monitor specifications, causing an input signal frequency mismatch. To resolve this, check the compatibility of your graphics adapter and monitor specifications. For non-standard signals, use the OSD to adjust the 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 or disconnecting the signal cable or powering off the monitor.

  If you're experiencing abnormal sound on your Acer monitor (audio-input model), first check that the audio cable connecting the monitor to the host PC is properly connected. Also, verify that the volume setting on the host PC is not set to the minimum. If it is, try increasing the volume level.
