What connection should I use?

Your TV has several connection types for connecting devices to your TV. For the best video quality, you should connect a device to the best available connection. Use the following tables to identify cables:

Cautions

  • Check the jacks for position and type before making any connections.
  • Loose connections can cause poor audio or video quality. Make sure that all connections are tight and secure.
  • The external audio/video devices shown may be different from your devices. If you have questions, refer to the documentation that came with your devices.
  • Always turn off your TV when connecting external devices.

Benefits of connecting

Connecting brings out your TV's full potential!

Make any night a movie night

Thousands of movies to choose from, across all major streaming movie channels like Netflix, Cineplex Store, Crackle, and more. You’ll never run out of something new to watch.

Get in the groove

Stream endless hours of music from channels free and subscription-based like Spotify, VEVO, and Rdio. With almost instant access to thousands of music artists, your favorite beats are just as close as your remote.

Explore your passions

In addition to popular streaming channels like YouTube, NHL, Sky News and Cineplex Store, your TV also offers hundreds of streaming channels to fuel your passions—including fitness, cooking, religion, outdoors, International programming and much more.

Enjoy FREE trials of popular channels

Your TV comes loaded with special offers, including free trials from popular streaming channels Netflix, Spotify, Rdio, DailyBurn Fitness, and many more. But remember that you must cancel before the free trial ends to avoid subscription fees.

What is streaming?

Streaming is viewing or listening to video or audio content that is sent over the Internet, or located on a network-connected media server or on a USB device plugged into your TV’s USB port.

With streaming, you can buy or rent most programs on demand, when it’s convenient for you. When streaming, you can play, pause, rewind, and fast forward whatever you are watching. You can also replay the last few seconds again, or turn on closed captions.

Your TV lets you choose from thousands of streaming channels that offer a huge selection of entertainment:

  • Thousands of movies and TV episodes
  • Unlimited music, live and on-demand
  • Tons of live and on-demand sports
  • Commercial-free kids programming
  • International programming in 22 languages
  • 24x7 news and in-depth news commentary

Many streaming channels are free. Some streaming channels, like Cineplex and Amazon Instant Video, let you purchase or rent the latest movie releases or popular TV series. Some channels such as Netflix or Spotify charge a monthly subscription fee and others are free if you subscribe to a companion service through your cable or satellite provider. For example, HBO subscribers with participating broadcast TV provider accounts can add the HBO Go channel and watch it for free. If you have an existing subscription to a service like Netflix or Spotify, you can just sign in with your existing user name and password.

To play streaming content that is available on the Internet, you add streaming channels to your Home screen. To add a streaming channel to your Home screen, use the Streaming Channels option on the Home screen menu to go to the Roku Channel Store, and then select the streaming channel you want to add. The streaming channel is then added to your Home screen, and you can watch it at any time.

For more information on using the Roku Channel Store feature, see Using the Roku Channel Store

But what if I didn’t connect my TV?

What if you went through Guided Setup and chose Connect to the Internet later? No worries. Your TV makes it easy to connect whenever you want. As you move around the Home screen, you’ll see several places where you can start the connection process. For example:

  • Now and then you'll see a message appear on the panel to the right of the Home screen offering a Connect Now option. Simply highlight and select the Connect Now option to get started.
  • Use the Connect and activate now option in the Settings menu. From the Home screen menu, select Settings, Network, and then Connect and activate now.
  • If you want to start over from the beginning, use the Settings menu to do a Factory reset, and then go through Guided Setup again. This time, choose your home network when prompted.

Regardless of how you connect, the process is the same. If you need details, see Step 3 under Setting up your TV

Using your TV

This section provides information on using the day-to-day features of your TV.

Status light

Your TV has a single status light on the front panel. It goes on and off and blinks in different ways depending on the status of the TV, as shown in the following table:

Standby mode energy savings

When you turn off your TV, it may remain in a higher power mode for a few minutes, after which it goes into a very low power standby mode. If you turn on the TV again before it has entered the very low power mode, it turns on immediately. After the TV goes into the lower power standby mode, it takes a bit longer to start up.

Watching broadcast TV channels

To watch broadcast TV, select the Antenna TV tile in the Home screen. Your TV remembers the last channel you watched and starts with that channel playing.

Changing channels

To change channels, you can do any of the following:

  • Press the UP arrow to change to the next higher channel.
  • Press the DOWN arrow to change to the next lower channel.
  • Press the LEFT arrow to display the channel list, and then press the UP and DOWN arrows to move the highlight through the list one channel at a time. Or press REWIND and FAST FORWARD to move the highlight through the list one page at a time. When you’ve highlighted the channel you want to watch, press OK. (If you decide you don't want to change channels, press the RIGHT arrow or BACK button).
  • Press to switch to the previously tuned channel.

Viewing program information

To view information about the current program, press OK. Your TV displays a banner at the bottom of the screen with as much information as is available in the program data stream, as shown in the following example.

Switching TV inputs

Switch to a TV input to access the device connected to that input, for example, a Blu-ray player. Switching inputs is as simple as highlighting the input’s tile in the Home screen, and pressing OK. The video signal on the input, if any, appears on the screen.

Auto-detecting devices

Your TV automatically detects when you connect a new device to an HDMI input and turn on its power. The input is automatically added to the Home screen if it isn’t already present.

Adjusting audio/video settings

While watching video content on any input, press to display the Options menu. Press the UP and DOWN arrows to highlight an option, and then press the LEFT and RIGHT arrows to change the setting. Adjusting TV settings on page 51 explains each of the settings in detail.

Playing content from USB storage devices

Your TV has a USB port that can be used to play personal music, video, and photo files from a personal USB flash drive or hard disk. If your TV is connected to the Internet, your Home screen has the Roku Media Player tile. If your TV has not been connected to the Internet, the Home screen has the USB Media Player tile.

To use this feature, first make sure your media files are compatible with the Roku/USB Media Player. As of the publication date of this guide, the following media file formats are supported:

  • Video—MKV (H.264/262), MP4, MOV (H.264)
  • Music—AAC, MP3, WMA, WAV (PCM), AIFF, FLAC, and AC3, and DTS
  • Photo—JPG, PNG (up to 4k x 4k pixels)

To see the latest list of supported formats, view Help in the Media Player.

Playing content from local network media servers

If you have connected your TV to a network, it can play personal video, music, and photo files from a media server on your local network. Media servers include personal computers running media server software such as Plex or Windows Media Player, network file storage systems that have built-in media server software, and other devices that implement the specifications of the Digital Living Network Alliance. Some servers do not fully implement the DLNA specification but are UPNP (Universal Plug and Play) compatible. The Roku Media Player will connect to them as well. Some media servers can convert files into Roku compatible formats. DRM-protected content is not supported.

Using your TV in a hotel or dorm room

Hotels, school dorms, conference facilities, and similar locations with public wireless Internet access often require you to interact with a web page to authenticate your access. These restricted public networks are commonly known as captive portal networks. When you select a network of this type, the TV automatically detects that additional information is needed and prompts you through using another wireless device to supply the requested information.

To connect your TV to the restricted network:

1 Either during Guided Setup or after selecting Settings > Network > Set up new Wi-Fi connection, you’re presented with a list of available networks.

2 If you select a network that requires interaction to grant access to the Internet, the TV detects that additional information is needed and displays the following prompt.

3 If you selected the correct network, highlight I am at a hotel or college dorm, and then press OK. The TV prompts you to use your smartphone, tablet, or laptop to complete the connection.

4 Use a phone, tablet, or wireless-enabled computer to detect wireless networks. In most cases, you can simply open the device’s Wi-Fi Settings or Network Settings screen to start scanning.

5 Connect to the network named on your TV screen. The actual network name varies.

6 The wireless connection process prompts you for a password. Enter the password as shown on the TV screen. The actual password varies.

7 Start the web browser on your smartphone, tablet, or computer. When you attempt to open any web page, the restricted connection will prompt you for whatever information it needs. In most cases, you must agree to terms and conditions, provide identifying information, or enter a password, PIN, or room number to proceed. The information requested depends on the organization that controls the wireless connection.

8 After you enter the requested information, the TV automatically proceeds to complete its connection and resumes normal operation.

9 If the TV prompts you to link to your Roku account, use your smartphone, tablet, or computer to complete the pairing operation and activate your Roku TV.
