  If your Acer monitor is not displaying a picture, here are some troubleshooting steps depending on the LED status: * If the LED is on, use the On-Screen Display (OSD) menu to adjust the brightness and contrast to the maximum settings, or reset them to their default values. * If the LED is off, check the power switch and ensure the AC power cord is properly connected to the monitor. * If the LED is flashing, make sure the video signal cable is securely connected to the back of the monitor and verify that the computer system is powered on.

  If the display on your Acer monitor is missing, shifted, or too small or large, use the On-Screen Display (OSD) to adjust the RESOLUTION, CLOCK, CLOCK-PHASE, H-POSITION, and V-POSITION settings, especially when using non-standard signals. Also, if the full-screen image is missing, try selecting a different resolution or vertical refresh timing.

  An unstable picture on your Acer monitor may be due to a mismatch in specifications between the graphics adapter and the monitor, leading to an input signal frequency mismatch. Check if the specifications are in compliance.
