Using your Marshall monitor is easy. First, connect the monitor to a power source using the included power supply. Then, use a 3G-SDI cable to connect it to your video source. You can place it on your desktop or mount it on a wall using a VESA-compatible mount. When using it, keep it away from direct sunlight and heat sources. To clean the monitor, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Regularly check the connections to make sure they are secure. If you encounter any issues, contact our customer support team.
