Hello! I'm just wondering if this is a software issue but I've tried everything from changing HDMI cables to making sure that video actually plays on my mac and etc... but none of the movies/shows on my Apple TV streaming app display any video on my monitor and can only hear audio. Is this a software or hardware issue? I did try connecting my mac directly to my monitors with HDMI and VGI cable as well as trying other types of docking stations and they actually work. I only experience this issue when I dock my Mac to the Wavlink docking station. I hope someone could help me troubleshoot this issue. Thanks!
