Playing content from USB storage devices

our 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.

Tips

• Using your Roku TV on a hotel or dorm room network requires wireless availability and use of your network-connected smartphone, tablet, or computer to authenticate access to your account.
• Your TV must already be running software version 7.0. You can find the version number by navigating from the Home screen to Settings > System > About. If it is running an earlier software version, you must use a non-restricted wireless network to link and activate the TV, and then update the software to version 7.2.
• Be sure to bring your Roku TV remote control, because the Remote feature of the Roku mobile app may not work when connected to a hotel or dorm room network.
• Content might be limited or unavailable if you try to connect outside your home country due to geo-filtering.

To connect your TV to the restricted network:

1. Either during Guided Setup or after selecting Settings > Network > Set up new wireless 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.

Adjusting TV settings

You can adjust most picture and sound settings while you are watching a program by pressing * to display the Options menu. If you don’t find what you need, there are additional picture and sound settings in the Settings menu. In most cases, the changes you make apply only to the input you are using. Antenna TV, each separate HDMI® input, and the AV input have their own settings that your TV remembers when you return to that input. Your TV also remembers the settings you specify while viewing streaming content.

Settings menu

Use the Settings menu to adjust overall TV settings. Press to go to the Home screen, and then navigate to Settings > TV picture settings. You can adjust the following overall TV picture settings from the Settings screen:

• TV brightness—If the lighting level in your TV room changes, use this setting to help provide a better viewing experience; set to darker for a darker room, and brighter for a brighter room. Choose among Normal and four other settings to make the overall picture brighter or darker. So that you don’t have to make this type of change for each TV input one at a time, this setting increases or decreases your TV’s general brightness across all TV inputs. This setting is identical to the TV brightness setting you can access in the Options menu while watching a program.
• Settings per input—This section of options lists each TV input. Select an input to switch to that input. Then press * to display the Options menu, where you can adjust the input's settings while watching a live picture and listening to the sound from that input.

Tip You don’t have to go to the Settings menu first—you can display an input's Options menu and adjust its settings whenever you are watching the input by pressing *.

Options menu

• The Options menu for each TV input provides settings for controlling the appearance of the picture and the quality of the audio. To view the Options menu, press * whenever you are watching a TV input or streaming a video. The Options menu is a panel that appears over the left side of the screen:

• To adjust the settings on the Options menu, press the UP or DOWN arrow to highlight a setting, and then press the LEFT or RIGHT arrow to change the setting. You’ll notice the changes you make right away in picture appearance or audio quality.
• Tip When you highlight a setting, the header text explains the effect of its current value. When you begin to adjust a setting, the other options are hidden so you can see more of the screen. Even though the other settings are hidden, you can move the highlight up or down to adjust the other settings.

Options menu settings

• TV brightness—Affects the overall brightness of the picture. This setting applies across your entire TV; that is, to all TV inputs and is identical to the TV brightness setting under Settings > TV picture settings.
• Picture mode—Provides picture presets for various viewing preferences. This setting applies to the currently-selected input only.
• Picture size—Adjusts the aspect ratio of the picture, enabling you to view a picture in its original format, or zoom or stretch it to fill the screen. The Auto setting has been found to produce the best picture in most cases.
• Audio effect—Adjusts the sound quality output from your TV speakers. This setting applies across your entire TV; that is, to all TV inputs. It does not affect the sound quality for headphones, HDMI 1/ARC, or DIGITAL OUTPUT (OPTICAL) (TOSLINK) connectors.
• Sleep timer—Sets a timer that turns off your TV after the specific amount of time. This setting remains in effect even if you stop watching the current input.
• Closed captioning—Controls when you see captions. This setting is only offered for Antenna TV, the AV input, and streaming videos. Any set value remains in effect across only these inputs.
  • Antenna TV—Turn captions on or off, or set them to appear only when your TV sound is muted.
  • AV input—Turn captions on or off, or set them to appear only when your TV sound is muted.
  • Streaming video channel—Turn captions on or off, set them to appear only when your TV sound is muted, or only during instant replay (for streaming content that supports instant replay).
• Captioning track—Selects which caption track to display when Closed Captioning is on. This setting remains in effect on all inputs that provide captions.
• SAP—Selects whether to play a secondary audio program or multichannel television sound, and which choice to play. This setting applies only to Antenna TV on digital channels

Changing privacy settings

By default, when connected to the Internet and activated with your Roku account, the TV uses an advertising identifier to track your usage behavior. You can change the privacy settings on your TV in two ways: resetting the advertising identifier and limiting ad tracking.

Resetting the advertising identifier

Resetting the advertising identifier has the effect of clearing your prior usage history and starting over. From that point forward, your new usage patterns affect the advertisements you see on your TV. To reset the advertising identifier:

1. From the Home screen menu, navigate to Settings > System > Privacy.
2. Highlight Reset advertising identifier. Press * to view more information about this option. When you finishing reading the information, press OK to close the More Information window.
3. Press OK to reset the advertising identifier, and then press OK again to dismiss the verification message.

Limiting ad tracking

You can limit Roku’s tracking of your usage behavior by limiting ad tracking. When you do, your TV will display ads that are not personalized based on your TV’s advertising identifier. To limit ad tracking:

1. From the Home screen menu, navigate to Settings > System > Privacy.
2. Highlight Limit ad tracking. Press * to view more information about this option. When you finish reading the information, press OK to close the More Information window.
3. Press OK to select the Limit ad tracking option.

Customizing your TV

There are several things you can do to personalize your TV.

Rearrange tiles

Whenever you add a TV input tile, it’s added at the top of your Home screen. Whenever you add a new streaming channel from the Roku Channel Store, it’s added at the bottom of your Home screen. You can easily rearrange the order of the tiles on the Home screen to suit your viewing preferences. For example, you might want Antenna TV to be the first tile in your Home screen. But if you mostly watch one streaming channel, you might want its tile to be the first one on your Home screen.

Rearranging tiles is easy:

1. From the Home screen, highlight one of the tiles you want to move.
2. Press * to display a list of options for the type of tile you selected.
3. Select Move input. The list of options disappears and the highlighted tile shows arrows indicating how it can be moved.
4. Use the arrow buttons to move the highlighted tile to its new position. As you move the tile, it pushes other tiles out of its way.
5. Press OK to lock the tile into its new position.
6. Repeat these steps to move other tiles until you have arranged your Home screen to your liking.

Edit broadcast TV channel lineup

• When you set up the TV tuner as described in Setting up Antenna TV on page 42, your TV adds all the channels with good signals that it could detect in your area. It’s likely that you now have more channels than you want in your channel list.
• To edit the channel lineup, from the Home screen, navigate to Settings > TV inputs > Antenna TV > Edit channel lineup. You’ll see a screen listing all of your channels. Adjacent to the list of channels is a miniature TV screen playing the highlighted channel's picture and sound.

• Highlight each channel you want to hide, and then press OK to hide the channel.
• Tip If you need to see or hear the highlighted channel, wait a couple of seconds for your TV to start playing the channel’s picture and sound. Also note that if you've enabled parental controls and the program on the current channel is blocked, you won’t see a picture or hear sound while editing the channel lineup

Rename inputs

• Rather than trying to remember that your Blu-ray player is connected to HDMI 1 and your game console is connected to HDMI 3, you can rename the TV inputs to match the connected component.
• Tip Renaming an input also changes the icon associated with it.

To rename an input, you can either:

• Highlight the input tile in the Home screen, and then press * to display a list of options. From the list of options, select Rename input. Then select a new name and icon. or
• From the Home screen, navigate to Settings > TV inputs. On the TV inputs screen, select the input you want to rename, select Rename, and then choose a new name and icon from the provided list. Press to return to the Home screen. The new name and icon are now in effect.

Remove unwanted tiles

It’s easy to remove unused TV inputs and unwanted channel or app tiles. For example, if you never use the HDMI 3 input, or if you don’t like the weather app you added from the Roku Channel Store, you can remove them from your Home screen.

Tip You also can remove the Antenna TV tile if you never use the TV tuner. But be aware that removing the Antenna TV tile also deletes the broadcast TV channel list. You’ll have to set up the TV tuner again next time you want to view broadcast TV. Instructions for setting up the TV tuner can be found in Setting up Antenna TV

• To remove any tile, highlight the input tile in the Home screen, and then press * to display a list of options. From the list of options, select Remove input. In the screen that follows, confirm you want to remove the input.
• Alternatively, to remove a TV input tile from the Home screen, navigate to Settings > TV inputs. On the TV inputs screen, select the input you want to remove, and then select Remove > Confirm. Then press to return to the Home screen.

Maintaining

• Do not use your TV in areas that are too hot or too cold, because the cabinet may warp or the screen may malfunction. Your TV works best in temperatures that are comfortable to you.
• Storage temperatures are 5° to 113°F (-15° to 45°C).
• Working temperatures are 41° to 95°F (5° to 35°C).
• Do not place your TV in direct sunlight or near a heat source.

Cleaning your TV cabinet
