I have got the latest http://plugable.com/products/mdp-hdmi/ with the above laptop and a Samsung UE40KU6400. Using switchresx I have the following questions/issues I’d appreciate some feedback on.
I can’t push refresh rate above 50Hz. I lose display completely with the tv saying no output detected.
Not sure if related, 50Hz is fine but weirdly 30Hz picture quality is poor but 25Hz looks fine. 30Hz looks like someone has put a filter over the whole display
I can’t get 4:4:4 chroma subsampling to work. I’ve enabled UHD color on HDMI1 but using test images I can clearly see it’s running 4:2:2.
