Roku Ultra (model: 4640) supports 720p HD, 1080p Full HD, 4K Ultra HD (UHD) and 4K Ultra HD HDR (High Dynamic Range) and ships with an Enhanced “point-anywhere” remote that supports voice search, remote finder, gaming buttons and private listening via a headphone jack on the remote.
Will Roku Ultra work with my TV?
Roku Ultra will work with any television with an HDMI® connection. However, you will not be able to take advantage of 4K resolution without a 4K compatible TV, or 4K HDR without a 4K HDR compatible TV. A compatible television is not the only requirement to stream movies and TV shows in 4K or 4K HDR; learn more about setting up your Roku player for 4K or setting up your Roku player for 4K HDR.
We recommend using a High Speed HDMI Cable if your TV only supports 720p and 1080p, or a Premium High Speed HDMI Cable if your TV also supports 4K or 4K HDR.
Setting up your Roku Ultra
- Follow along with the tutorial video below, or download the Quick Start Guide.
- Further help is available if you do not see video on your TV from the Roku Ultra or have problems with your remote control.
Going through Guided Setup
- Choose a language
- When your Roku Ultra powers on, the first screen will allow you to choose a language. All text and dialog within the Roku application will be displayed in the selected language.
- Scroll up and down the list and press the OK button on your Roku remote to choose a language.
- Note: It is the responsibility of the channel publisher to translate their channel and some channels may not support your chosen language.
- Connect your Roku Ultra to the internet
- Choose your wireless network from the list of available networks and enter your password. This is most often the same network you use to connect your computer or smartphone to the internet. If you do not see your network, select Scan again to see all networks. For more assistance, see help finding your wireless network and password.
- If you want to see your password as you type, choose Show password. This can help prevent entering the wrong password. Remember, passwords are case-sensitive – use the shift button on the on-screen keyboard to enter a capital letter.
- Once you have entered your password and selected Connect, your Roku Ultra will automatically connect to the internet. Alternatively, you can get more help if you are unable to connect to your wireless network.
- Wait for your Roku Ultra to download the latest software
- Once connected to the internet, your Roku Ultra will download the latest version of Roku OS software and then reboot.
- Set the display type
- Select Auto detect display type and your Roku Ultra will analyze the HDMI connection and determine the best display resolution so you don’t have to manually configure the settings. To change the display type at a later time, go to Settings > Display type.
- If support for 4K or 4K HDR is not detected and you are using a 4K compatible TV or a 4K HDR compatible TV, make sure all HDMI cables are firmly attached and all connections support HDCP 2.2. For more help, review the steps for 4K setup or 4K HDR setup.
