I have some trouble getting 4K out the HDMI output of Argon One cases. It is the same for four cases. It seems to require a good quality adapter to get 4K to work properly and the Argon adapter isn't quite up to the job at 4K but works great at 1080p.
Has anyone tried the Waveshare dual HDMI adapter at 4K? It looks extremely similar to the Argone One adapter.
I would pick up a few to try them but they are on back order. It must be a popular new product.
Thanks!
