More settings

Changing time settings

You can change time settings to suit your preferences. You can find the following settings by navigating from the Home screen menu to Settings > System > Time:

  • Sleep timer—Set a time delay after which your TV will automatically shut off. This setting reflects the setting you can make in the Options menu from any TV input, as explained in Options menu settings on page 52. Note that the sleep timer setting is not input specific.
  • Time zone—Select whether to set the time zone automatically or manually, and if set manually, select your current time zone. Typically, a TV connected to the Internet can discover its own time zone automatically, and a TV that is not connected to the Internet must be set manually. Initially, this setting is made when you set up the TV tuner, as explained in Setting up Antenna TV on page 43. Correct time zone information is needed to correctly display program data.
  • Clock format—Select whether to display time in a 12-hour or 24-hour format, or to turn off time display. This setting is available only on TVs that are connected to the Internet. Non-connected TVs do not display the time.

Using your TV in a home theater

Your TV has several features that make it an ideal TV for a home theater. But you might not notice them because they remain in the background until you decide to use them.

Turning off the speakers

When you use your TV with a sound bar or an external amplifier and speakers, you’ll probably want to turn off the internal TV speakers.

To turn off your TV’s built-in speakers, in the Home screen menu, navigate to Settings > Audio > TV speakers and change the setting.

Tip: Your TV’s internal speakers can be enabled and disabled automatically as needed by system audio control, as described in Enabling system audio control on page 69. The internal speakers are also turned off when you use the headphone jack.

Changing the audio mode

Your TV has two audio modes, accessed by navigating in the Home screen menu to Settings > Audio > Audio mode:

  • Stereo—Use this setting for internal speakers, headphones, and external stereo amplifiers connected through the HDMI 1/ARC, DIGITAL OUTPUT (OPTICAL), or headphone jack.
  • Auto—Use this setting to automatically detect the best audio setting based on the audio stream in the content you are watching. If you have connected your TV to an external Dolby Digital or Dolby Digital Plus compatible amplifier, receiver, or sound bar through HDMI 1/ARC or DIGITAL OUTPUT (OPTICAL), your TV automatically selects the appropriate surround sound capabilities of the device based on the characteristics of the current program.

Setting up a digital audio connection

You can connect your TV to an external amplifier, receiver, or sound bar by using either of these two connections:

  • HDMI ARC—The HDMI Audio Return Channel enables your TV to output digital audio on one of its HDMI connectors. The connected amplifier can also function simultaneously as an input source to your TV, if needed. To use the ARC capability, you must connect an HDMI cable from your amplifier's HDMI ARC connector to the HDMI 1/ARC connector on your TV. You also must:
    [IMAGE]
    • Be sure your HDMI cable is certified by HDMI.
    • Enable HDMI ARC under Settings > System > Control other devices (CEC), as explained in Enabling HDMI ARC on page 69.
  • SPDIF—Your TV has an DIGITAL OUTPUT (OPTICAL) connector that outputs a digital audio signal. To use the optical output, connect a digital optical audio cable from the amplifier to the DIGITAL OUTPUT (OPTICAL) connector on your TV.

Note: Dolby Digital Plus format is not available through the DIGITAL OUTPUT (OPTICAL) output. This format is only available through the HDMI 1/ARC connection.

After making the required HDMI ARC or digital optical audio connection, go to Settings > Audio > SPDIF and ARC option and select the audio format to use.

Note: In most cases, Auto detect is the best option. Other settings can result in no sound when the content you are viewing does not contain the audio stream type you selected.

Controlling other devices through CEC

Consumer Electronics Control (CEC) enables your TV and other CEC-compatible home entertainment components to control one another in various ways. First, the CEC-compatible devices must “discover” one another and report their capabilities. After this, one device can control another according to the features you enable. For example, playing a disc on a Blu-ray player could switch your TV to the Blu-ray player's input. Or, powering off your TV could also power off the Blu-ray player and the home theater receiver.

Discovering connected CEC devices

To discover CEC devices:

  1. Make sure that your CEC-compatible components are connected to your TV with a suitable high-speed HDMI cable that supports HDMI ARC and CEC control.
  2. Turn on each component and make sure all components have CEC enabled.
    Tip: Some manufacturers have their own branded names for CEC functionality, so you might need to read the product documentation to correctly identify the CEC features of the device.
  3. On your TV’s Home screen menu, navigate to Settings > System > Control other devices (CEC) and then select Search for CEC devices. Press OK to repeat the discovery process, if necessary.

When finished, your TV displays a list of CEC devices that are connected to each HDMI input, as well as any devices that had previously been connected. Your TV remembers the names of multiple CEC devices even when they are no longer connected. If the list is longer than the allowed space, press to see a complete list in a scrollable window.

Enabling HDMI ARC

HDMI 1/ARC is the audio return channel that is available on one of your TV’s HDMI ports. The audio return channel enables you to send a Dolby Digital audio signal back to a home theater receiver that is also sending an audio and video signal into your TV. Using HDMI ARC reduces the number of cables needed and optionally lets you control the volume and mute state of the receiver by enabling system audio control.

HDMI ARC is disabled by default. To enable HDMI ARC, in the Home screen menu, navigate to Settings > System > Control other devices (CEC), and then highlight HDMI ARC. Press OK to enable or disable the feature.

Note: Enabling HDMI ARC also enables System audio control. After enabling HDMI ARC, you can disable System audio control if you prefer.

Enabling system audio control

System audio control enables your TV remote control to change the volume and mute state of an amplifier or sound bar connected through HDMI, and to display the external device's volume and mute status in your TV’s on-screen display. Your TV automatically turns off its internal speakers and sends volume and mute control signals to an external amplifier when all of the following are true:

  • System audio control is enabled on your TV.
  • Your TV is connected to a CEC-compatible amplifier, it is powered on, and CEC discoverability is enabled.
  • The CEC-compatible amplifier's HDMI ARC connector is connected to your TV’s HDMI 1/ARC connector with a suitable HDMI cable.

When the CEC-compatible amplifier is off, your TV automatically turns on its speakers (unless you have turned them off as described in Turning off the speakers on page 68) and resumes local control of volume and mute state.

To enable or disable system audio control, in the Home screen menu, navigate to Settings > System > Control other devices (CEC) and highlight System audio control. Press OK to enable or disable the feature.

Enabling 1-touch play

1-touch play enables a component to control which TV input is active. For example, pressing Play on your Blu-ray player switches your TV to the Blu-ray input.

1-touch play is disabled by default. To enable 1-touch play, in the Home screen menu, navigate to Settings > System > Control other devices (CEC) and highlight 1-touch play. Press OK to enable or disable the feature.

Enabling system standby

The system standby feature causes other components to power off when you power off your TV. Depending on the CEC System Standby implementation, it also might enable connected components to power off your TV when you power off the component.

System standby is disabled by default. To enable system standby, in the Home screen menu, navigate to Settings > System > Control other devices (CEC) and highlight System standby. Press OK to enable or disable the feature.

Restarting your TV

You can restart your TV when necessary. Restarting has the same effect as unplugging your TV power and then plugging it in again.

To restart your TV, navigate to Settings > System > Power and then select System restart. Highlight Restart, and then press OK to confirm restart.

While your TV restarts, the screen goes dark for a few seconds, and then displays the startup screen for a few more seconds. When the restart operation completes, the TV displays the activity you selected in Power on settings on page 61.

Resetting your TV

You can choose to reset only your TV picture and audio settings to their original values, or perform a full factory reset to return your TV to the state it was in when you first unpacked and turned it on.

Reset audio/video settings

To reset only your TV picture and audio settings to their original values, navigate to Settings > System > Advanced system settings > Factory reset, and then highlight Reset TV audio/video settings. Read the information on the screen to make sure you understand what the reset operation does.

To proceed with the reset operation, press PLAY/PAUSE three times in a row.

Factory reset everything

A full factory reset returns your TV to its original, out-of-the-box state. When finished, you must repeat Guided Setup, reconnecting to the Internet, re-linking your Roku account, and reloading any streaming channels. You also must repeat Antenna TV setup and input configuration.

Factory reset is the recommended choice if you want to transfer your TV to another owner, and is the only choice if you want to switch from store mode to home mode (if you inadvertently selected store mode during Guided Setup).

To perform a factory reset, navigate to Settings > System > Advanced system settings > Factory reset, and then highlight Factory reset everything. Read the information on the screen to make sure you understand what this reset operation does. To proceed with the full factory reset, use the on-screen number pad to enter the code displayed on the screen, and then select OK to proceed.

When the factory reset operation completes, your TV restarts and displays the first Guided Setup screen.

What if I can’t access the Factory Reset option?

It is possible that your TV might get into a state where you cannot access the various menus, including the menu option that lets you perform a factory reset operation. If that happens, you can force your TV to reset by following these steps:

  1. Using a straightened paper clip or ball-point pen, press and hold the recessed RESET button on your TV connector panel.
  2. Continue to hold the RESET button for approximately 15 seconds.
    During this time, the status light turns off, and then turns on bright, and then pulses. When the reset cycle completes, the light either comes on dim (if your TV power was off when you started) or your TV screen comes on and the light turns off (if your TV power was on when you started).
  3. When the status light turns on steady dim or your TV screen comes on, release the RESET button.
  4. Proceed through Guided Setup. See Setting up your TV on page 35.

Changing your Roku Channel Store PIN preference

When you created your Roku account, you were given the opportunity to create a PIN code and to specify when it must be used. If you created a Channel Store PIN and want to change it, or you don’t remember your PIN, or if you didn’t create a Channel Store +PIN and want to add one, you can easily make these changes.

  1. On a computer, tablet, or smartphone, use your web browser to go to https://my.roku.com.
  2. Enter your email address and password to sign in. After signing in, the My Account page appears.
  3. Under PIN Preference, click Update to open the Choose Your PIN Preferences page.
