This version of EZCast called minibox can provide you up to 4K content casting to your TV, with quick and snappy quality. very small about of latency.
I am using it on my Projector but it works like charm to play any of my Netflix in 4K while we are a few rooms away from each other and the EZCast minibox is connected via 5Ghz Wi-Fi.
