I see that there is now 4K DisplayPort Adapter up to 3840×2160 available. Unfortunately it is only HDMI 1.4 with a 30 Hz refresh rate at this resolution. I was wondering by when we could expect to see HDMI 2.0 with 60 Hz for 4K.
Our USB to Video adapters all use technology by DisplayLink, and DisplayLink has not announced any chips that will support 4K@60Hz, so at this point we do not have any ETA if/when such an adapter will be available. Thanks for your interest in Plugable products!
Appreciate the prompt reply, Bob!
