Step 3: Select the upper-left Apple menu icon, go to “System Settings”, click on “Displays”, and choose the recommended resolution.

Step 4: Flip the USB-C cable that connects the docking station to the computer and plug it in again.

Step 5: Try connecting to other Thunderbolt ports on your Mac.

Step 6: In the upper-left Apple menu, go to "System Settings", click on "Displays" If the external monitor is recognized but displays no image, replace the HDMI cable. If the issue persists, contact iVANKY customer support.

Check Accessories and Connections

2. Screen Flickering

Check Accessories and Connections

Step 3: Install the latest macOS updates; these may include firmware updates for Apple-made monitors.


Note: If your monitor is not an Apple brand, ensure it has the latest firmware from the manufacturing company. Refer to the monitor's documentation or the manufacturer's website for details.
