Scan again for Antenna TV channels
There will be times when you need to create a new channel list. For example, you:
•
Change cable providers
•
Reorient your TV antenna
•
Move to a dierent city with dierent channels
Whenever you need to update your TV channel list, you can repeat the channel scan.
Tip: Repeat the channel scan from time to time to make sure you are receiving all of the latest
channels. Broadcasters add and remove channels, move channels to dierent parts of the
spectrum, and change the power levels of their channels periodically.
Note: Repeating the tuner channel scan unhides all hidden channels.
To repeat the channel scan, from the Home screen menu, navigate to Settings > TV inputs
> Antenna TV > Scan again for channels. Then select Start finding channels to begin the
channel scan process. The screens and options that appear during this process are identical
to those described in How do I set up the TV tuner?
HDMI® mode (4K models only)
On 4K (UHD) TVs, you can independently configure each HDMI® input to match the
capabilities of the connected device. From the Home screen menu, navigate to Settings > TV
inputs, and then select an enabled HDMI® input. Next, select HDMI mode and then select one
of the following settings:
•
Auto – Let the TV determine the best setting. Use this option unless your HDMI® device
does not correctly communicate its HDMI® version compatibility.
•
HDMI 1.4 – Configure the input for compatibility with HDMI® version 1.4, which supports
a maximum refresh rate of 30 Hz at full UHD resolution. Most HDMI® devices will work
correctly with the TV in this mode.
•
HDMI 2.0 – Configure the input for compatibility with HDMI® version 2.0, which supports
a maximum refresh rate of 60 Hz at full UHD resolution. You must use this mode to view
HDR content from the device connected to this HDMI® input. However, note that many
older HDMI® devices do not work correctly when the TV’s HDMI® input is set to this
mode.
Control by mobile apps
You can choose the level of control you want to allow your TV to accept from external
devices, such as smart phones, tablets, and virtual assistants. Device connect settings enable
other devices, including the Roku Mobile App, to control your TV over the local area network
