Do I need a second computer to show Bible verses on screen?

For most churches, no. A single computer can show scripture full-screen on the projector through a second display output and feed the same verse into your stream over NDI at the same time.

How can one computer send verses to both the projector and the stream?

The projector uses a physical display output in extend mode, while the stream receives the verse over NDI, which is a network output. Because these are different outputs, one machine can do both at once.

When is a dedicated graphics computer worth it?

For large multi-camera productions where the streaming PC is already working hard, or when you want to isolate presentation from streaming so one cannot affect the other. A typical church does not need one.

How to put Bible verses on screen without a second computer

A lot of churches assume that showing scripture properly — on the projector and in the stream — means buying and babysitting a second computer just for that. For most churches, it doesn't. Here's how to put verses on screen from a single machine, without the extra box, cost, or complexity.

Why people think they need a second PC

The traditional setup dedicates one computer to "graphics": lyrics, slides, and scripture. So when a church wants automatic verses feeding both the projector and the stream, the instinct is "that's another whole computer to buy, set up, and run." That's real cost, real desk space, and one more thing to fail on a Sunday.

But a second computer was always a workaround for software that couldn't do two jobs at once. You can often skip it.

What you actually need

To get verses on screen you need three things — none of which require a separate machine:

You need	On one computer
To detect/choose the verse	The app runs alongside your other software
To show it on the projector	A second display output (extend mode)
To send it to the stream	An NDI output into OBS/vMix on the same PC

Output 1: the projector, via a second display

Your presentation computer almost certainly has a spare display output. Run the projector as an extended display (not a mirror of your desktop) and send full-screen scripture to it while you keep your controls on the main screen. That's the whole projector side — no second computer, just a second output. See dual-monitor setup for church presentation.

Output 2: the stream, via NDI on the same machine

Here's the part people miss: NDI is a network output, not a physical one, so a single computer can send scripture into your streaming software over NDI while it drives the projector. If OBS or vMix runs on the same PC, the verse feed simply appears as a source — no capture card, no second box. New to NDI? Read NDI for churches.

The key realisation: one computer can output to a projector (physical display) and to your stream (NDI over the network) at the same time. The "you need a dedicated PC" advice is left over from older tools — modern software does both jobs from one machine.

Where TajiCast fits

This is exactly how TajiCast is built to run. On a single, ordinary church computer it:

Listens to the sermonDetecting the verse the preacher speaks, in real time.
Shows it on the projectorFull-screen, via your second display output.
Sends it over NDI to your streamInto OBS or vMix on the same PC — no extra hardware.

So both your in-room congregation and your online viewers see the verse, from one machine you already own.

When a second computer is worth it

To be fair, there are cases where a dedicated graphics PC still makes sense:

A large, multi-camera production where the streaming PC is already working hard.
You want to isolate presentation from streaming so one can't affect the other.
You're running heavy graphics and streaming and presentation together.

For a typical church, though — one projector, a modest stream — a single computer does the job comfortably. Don't buy hardware you don't need. Check your machine is up to it with what laptop you need for church presentation.
