Set up your player for 4K

How to set up your Roku® streaming player for 4K Ultra HD

The term “4K Ultra HD” (also known as 4K Ultra High Definition, 4K UHD, or just 4K) refers to the resolution of the TV, which is a measure of how much detail you can see on the screen. The resolution of a traditional 1080p Full HD TV is limited to 1,920 columns and 1,080 rows of pixels, while a 4K Ultra HD TV has an increased resolution of 3,840 columns and 2,160 rows of pixels. With four times the resolution of 1080p, 4K Ultra HD offers improvement in picture clarity over existing HD resolutions.

Requirements

The following are required to enjoy 4K content on a compatible Roku player.

  • Compatible 4K TV with an available HDMI 2.0 input that supports HDCP 2.2
  • Roku player capable of streaming 4K
  • Good internet connection with enough bandwidth to stream 4K (up to 25 Mbps may be needed)
  • Streaming service like Netflix, Apple TV, or Disney+ with a plan that supports streaming in 4K
  • Premium High Speed HDMI® Cable (*not needed when connecting a 4K-compatible Roku Streaming Stick® directly to a compatible TV)

HDMI 2.0 and HDCP 2.2

To successfully stream 4K Ultra HD content, all devices connected to your compatible Roku device must support HDMI 2.0 and HDCP 2.2. This includes your TV, an AVR, and any other devices connected in between. If even one device does not support HDMI 2.0 and HDCP 2.2, then the 4K movie or TV show can only be viewed in a lower resolution, such as 720p or 1080p.

HDCP 2.2 is a copy and content protection standard required by the TV and movie industry. Some older 4K Ultra HD TVs do not support HDCP 2.2, while others may only support HDCP 2.2 on a single HDMI input. Learn what to look for when trying to identify an HDMI input that supports HDCP 2.2.

Audio/video connections

Once you confirm your other devices support HDMI 2.0 and you identify the inputs that support HDCP 2.2, use the instructions below to connect your Roku player.

To begin, firmly attach a Premium High Speed HDMI Cable to the HDMI port on the back of your Roku player. If you are connecting a Roku Streaming Stick, it connects directly to an HDMI input and does not require an HDMI cable.

Once your Roku player is ready to be connected to your other devices, use the recommended option below that matches your configuration.

  • Tip: An AVR or soundbar can be complicated to configure. If you have trouble, consider seeking help from a professional audio/video installation service like the Best Buy Geek Squad.
