Check Connections: First, ensure all physical connections are secure. Disconnect and reconnect the cable connecting your monitor to the Mac. Try using different ports and cables if available.
-
System Preferences: Navigate to System Preferences > Displays. Click on Detect Displays to make sure your Mac identifies the monitor correctly. Here you can make necessary adjustments to resolution and refresh rates.
-
System Report: Click the Apple logo in the top-left corner of the screen, select About This Mac, and then System Report. Under the Graphics/Displays section, you’ll find detailed information about the monitor, including its status and any issues detected by macOS.
-
Third-Party Applications: Consider using third-party diagnostic tools that can provide more in-depth analysis of your monitor’s performance and any connected devices. Apps like SwitchResX can be helpful for advanced configurations and diagnostics.
-
Update Software: Ensure that macOS is up-to-date. Go to System Preferences > Software Update and install any available updates. Updates often include fixes for known issues and improved hardware compatibility.
