Trying to use the HDMI over IP extender ST12MHDLAN4K with a “Club 3d” brand USB-C dock so users have a single cable to plug into in our boardroom. If I connect a laptop directly via hdmi to the ST12MHDLAN4K it works fine, but if I plug the ST12MHDLAN4K into the dock, and then attach my laptop to it, the display isn’t detected. Are there any firmware updates or anything I can try to get the ST12MHDLAN4K to be recognized? Thanks.
Hello @haximo and thank you for your interest in our Community.
Having the laptop’s direct HDMI output work fine on our extender does confirm that the extender itself is working correctly. Have you tested that same laptop + that same dock but on a direct monitor or TV (without our ST12MHDLAN4K)?
Our extender does not install or use any drivers on a computer: it simply takes any HDMI video signal and simply extends it over distance. From your description, I would first verify that the output on the dock is indeed functional (for example, the dock may require either drivers, or for your laptop to support DP Alt Mode over USB-C).
I look forward to hearing back from you.
