If your Acer monitor isn't displaying a picture, try these steps: First, use the OSD menu to maximize the brightness and contrast settings, or restore them to their default levels. Check that the power switch is turned on. Ensure the AC power cord and video signal cable are securely connected to the monitor and that your computer is powered on.
Why does my Acer T231H 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 issue. To resolve this, use the OSD to adjust the RESOLUTION, CLOCK, CLOCK-PHASE, H-POSITION, and V-POSITION settings, especially with non-standard signals. If the full-screen image is missing, try selecting a different 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 only), first check that the audio cable is properly connected to the host PC. Also, verify that the volume level on the host PC isn't set to the minimum; if it is, try increasing the volume.
