# Show captions on a TV

> Pair a TV once, and it shows the captions by itself whenever you caption.

The TV is the screen everyone in the room already looks at. Readout shows the captions there in big
type, while you keep captioning from your phone, tablet or computer.

There are three ways to get them there. Start with the first; the others take over the switching
for you.

> [tab] The TV's web browser
>
> Works on most smart TVs with a web browser, including LG TVs from 2016 and Samsung TVs from 2017.
>
> **1. Open the TV page**
>
> In the TV's web browser, go to **readout.tv/tv**. It shows a code and a QR code.
>
> **2. Pair it from the app**
>
> In the app, tap **TVs and phones** at the top, and type the code the TV shows. Or scan the QR
> code with the phone you caption on, and confirm.
>
> **3. Caption**
>
> From now on, the TV joins by itself whenever the app is open. Between conversations it shows
> **Ready for captions** instead of a code.
>
> > [!TIP]
> >
> > On an LG TV, Quick Access puts the captions one button away: with the captions page open,
> > press and hold a number key on the remote and assign the browser to it. Holding that key then
> > opens the captions, and Back returns to what you were watching.

> [tab] With the home agent
>
> The [home agent](https://docs.readout.tv/home/home-agent.md) is a small program on a computer at home that stays on. With it,
> the app can open the captions in the TV's browser, switch the TV to the input they're on, or
> cast them to a Chromecast, with one tap: **Show captions** beside the TV in **TVs and phones**, or
> at the top of the [remote](https://docs.readout.tv/home/remote.md). **Stop captions** switches the TV back to what it was
> showing.
>
> In the TV's settings (its gear in **TVs and phones**), **Switch when captioning starts** makes it
> happen by itself.

> [tab] Readout's screen
>
> A Raspberry Pi plugged into the TV is [Readout's screen](https://docs.readout.tv/home/raspberry-pi.md). It shows the captions
> itself and switches the TV to them over HDMI, whatever the TV's brand. It's the most hands-off
> way, and it brings reminders, video calls, captions of the room and more.

## A TV is the whole household's

A paired TV belongs to your account, not only to the phone that paired it. Everyone signed in to the
account sees it in **TVs and phones**, and can rename it or forget it.

The TV shows one device's captions at a time. To show yours instead, tap **Show here** beside the
TV; it says who has it now.

## Text size on the TV

**Menu → Display** sets how the captions look, on the TV too. The TV's text size has buttons of its
own, **Bigger text on TVs** and **Smaller text on TVs**, so the TV can be big while your phone stays
readable.

## Pairing it with someone else

A paired TV shows no code, so nobody who can see the screen can take it over. To pair it with
another account, forget it in **TVs and phones** and it shows a code again. Or, on the TV's
**Ready for captions** screen, choose **Pair with a different device** with the TV's remote.

> [!NOTE]
>
> A TV whose browser is too old says so where the code would be. Use screen mirroring, or a
> streaming stick or a Raspberry Pi on one of the TV's inputs, instead.
