The Display Built-In Self-Test (BIST) is a diagnostic test that many monitors and display devices can perform to check their functionality and identify potential issues. The exact method for initiating a BIST can vary depending on the monitor’s make and model. Below are some general steps that might apply:
- Ensure Power and Connections:
- Make sure the monitor is properly connected to a power source and the computer (or any other source) and is turned on.
- Turn Off the Monitor:
- If the monitor is not already off, turn it off using the power button.
- Unplug the Monitor:
- Unplug the monitor from the power source. Some monitors may require you to unplug them from both the power source and the computer.
- Press and Hold Specific Buttons:
- Some monitors have specific buttons or a combination of buttons that need to be pressed and held simultaneously to initiate the BIST. Commonly, this involves holding the power button and one or more other buttons.
- Plug in the Monitor While Holding Buttons:
- While still holding the designated buttons, plug the monitor back into the power source.
- Release Buttons and Turn On the Monitor:
- After plugging the monitor back in, release the buttons, and then turn on the monitor using the power button.
- Observe the Display:
- The monitor should perform a BIST sequence. This typically involves displaying a series of test patterns or solid colors. The purpose is to check if the monitor’s pixels and overall display functionality are working correctly.
- Check for Issues:
- Pay attention to any abnormalities during the BIST. If you notice flickering, color issues, or other anomalies, this may indicate a problem with the monitor.
- Monitor’s Documentation:
- If the monitor’s BIST process is not working or if you’re uncertain about how to initiate it, consult the monitor’s user manual or the manufacturer’s website for specific instructions.
