These Marshall monitors are easy to use. First, connect your video source to the monitor using the appropriate cables. Since there's no power supply, you'll need to get a compatible one on your own. When using, place the monitor in a well - ventilated area to avoid overheating. To keep it in good condition, clean the screen regularly with a soft, dry cloth. Avoid using harsh chemicals. Also, don't expose the monitor to direct sunlight or extreme temperatures. That's it, enjoy using your Marshall monitors!
