How to project worship lyrics from your phone to a TV

You don't need a laptop to run projection at church. You need a phone, a screen, and one of four ways to connect them. Here they are, best first.

GoSlide is built in two halves: a controller that you drive from your phone, and an output view that shows the words. The question on this page is just how to get that output view onto the big screen.

Option 1 — Smart TV, opened directly (best quality)

If your TV has a built-in web browser and can reach the internet, this is the cleanest setup available and it costs nothing.

1. Open the TV's web browser.
2. Go to goslide.app/tv.
3. On your phone, open goslide.app/app and pair it with the code shown on the TV.

Why this is best: the TV renders the text itself at full native resolution, so the words are perfectly sharp. Your phone is only sending control signals, which means you can lock your phone, take a call, or check a message without anything appearing on the church screen. Battery drain is minimal.

Option 2 — Miracast receiver on a normal TV

This is the answer if you have an ordinary TV with an HDMI port and no smart features. A Miracast receiver (a small wireless display dongle) plugs into HDMI and mirrors your Android phone's screen to the TV.

1. Plug the Miracast receiver into the TV's HDMI port and power it (usually USB).
2. Switch the TV to that HDMI input.
3. On your Android phone, open Cast / Smart View / Wireless display in the quick settings panel and connect to the receiver.
4. Open goslide.app/tv in your phone's browser and put it full screen. It now shows on the TV.

Note that Miracast mirrors the phone, so the phone is dedicated to being the screen. If you want to control slides from the same phone you are mirroring, you'll be looking at the output view rather than the controller. The usual fix is two devices: one phone mirrors the output, another phone or tablet runs the controller. They stay in sync automatically.

Option 3 — Chromecast

Similar to Miracast in practice. Plug the Chromecast into HDMI, cast your Android screen from the Google Home app, then open the output page. The same Do Not Disturb and screen-lock advice applies.

If the Chromecast is on a TV that also has a browser, prefer Option 1 — it will look better.

Option 4 — Wired HDMI adapter

The most reliable option of all, because nothing depends on the network being cooperative.

• Android: a USB-C to HDMI adapter, if your phone supports video output over USB-C. Not every phone does — check before buying.
• iPhone: a Lightning or USB-C to HDMI adapter, depending on your model.

Plug in, switch the TV to that input, open the output page full screen. No pairing, no lag, no dropouts. The downside is the obvious one: your phone is tethered to the screen by a cable.

Which should you choose?

Short version: if the screen can open a web page, let it. Mirroring is the fallback for screens that can't, and it works perfectly well — just remember Do Not Disturb.

Common questions

Will this work with a projector instead of a TV?

Yes. Everything above applies to any display with an HDMI input. A Miracast receiver in a projector's HDMI port behaves exactly the same way.

Do I need internet during the service?

For the initial pairing, yes. After that GoSlide works offline — the songs and scripture are stored on the device. With a wired HDMI setup you can run an entire service with no internet at all.

Can two people control the screen?

Yes. More than one controller can connect to the same output, which is useful when the worship leader wants to drive songs and someone else handles scripture.

Does an iPhone work with Miracast?

iPhones use AirPlay rather than Miracast. Use an AirPlay-compatible receiver, a smart TV that supports AirPlay, or a wired adapter.
