What to do if my Acer Monitor has no picture?

  Christopher KingJul 31, 2025
  If your Acer monitor isn't displaying a picture, there could be several reasons. First, if the LED is on, use the OSD to adjust the brightness and contrast to the maximum or reset them to their default settings. If the LED is off, check the power switch. Ensure the AC power cord is properly connected to the monitor. If the LED shows an amber color, verify that the video signal cable is properly connected at the back of the monitor. Finally, make sure the computer system is powered on.

Why is my Acer B233HL picture unstable?

  Tara WilsonAug 10, 2025
  An unstable picture on your Acer monitor may be due to a mismatch between the graphics adapter and monitor specifications, causing an input signal frequency mismatch. Check these specifications for compliance. You can also use the OSD to adjust RESOLUTION, CLOCK, CLOCK-PHASE, H-POSITION, and V-POSITION, especially with non-standard signals. 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 your Acer monitor (audio input model) has abnormal sound, first check if the audio cable is properly connected to the host PC. Also, verify that the volume setup on the host PC is not at the minimum level, and try increasing the volume.
