The Roku 4 is the first Roku device to support 4K ultra high definition video (UHD), making it easier to find and stream 4K content from different online sources. The Roku 4 has a rocking quad-core ARM processor, an 802.11ac Wi-Fi antenna and 1.5GB of RAM. This allows the system to play 4K TV shows and movies. In general, 4K content is still hard to find, but the Roku 4 helps you get more out of your 4K TV investment sooner.

The Roku 4 is the first streaming box from the company to house an optical audio out connection, a huge boon for A/V enthusiasts.  Other interfaces include HDMI 2.0, USB 2.0, and 10/100 Base-T Ethernet. There is also a microSD card slot that will support up to 128GB of extra storage.

The Roku 4 works with 4K TV's like the Samsung UHD 4K Flat Smart TV- JU6000.  Just connect a HDMI cable between the Roku and the Samsung TV and you should be able to establish a HDMI 2.0 connection supporting 4K video.

To enable video streaming on the Roku 4, we need to have an Internet connection. To set up Internet on the Roku 4, go to Settings -> Network -> Wireless ( Wi-Fi ), make appropriate W-Fi selection, and just connect. Make sure your Internet connection has at least 20 Mbp/s download speed to stream 4K video.

Once the Roku is connected, it takes you to the Channel store. Here you have variety of channel options to choose from. Some channels require payment. Availability can change depending on which country you are in.  On the remote, you have dedicated buttons for quick access to popular channels like Amazon Instant Video, Hulu, and Netflix.

 

 

Content and the general user interface from the Roku 4 looks really good on the Samsung UHD 4K Flat Smart TV- JU6000 and hopefully over time quality 4K content will become ubiquitous.  Until then, Roku has found a way to make it easier for you to find 4K content no matter its source.
