In short

The Desview T3 is a beam-splitter teleprompter accepting phones and small tablets up to roughly seven inches. Any teleprompter with mirror mode will drive it, including ScrollCue, which is free, browser-based, and requires no app download.

What fits

The T3 accepts a device up to roughly seven inches, which in practice means any phone including the largest Pro Max sizes, and some of the smaller tablets if you measure first. Check yours before you order rather than after.

Running it

Open ScrollCue in the browser on whatever device you are mounting. Turn on mirror mode. That is the setup. There is nothing to install, no account, and it does not care that the rig says Desview on it.

Mirror mode, always

The glass flips the text. Without this you are reading backwards and will conclude, wrongly, that your rig is faulty.

Font 48 to 56 px on a phone, 56 to 64 on a small tablet

Go bigger than feels necessary on a desk. Reading through glass costs you contrast.

Brightness up

The beam-splitter is only reflecting some of the light back at you. What looked bright in your hand will look grey under glass.

Red dim mode, if you are on a dark set

The reverse problem. A bright phone under glass on a dark stage will bounce light everywhere and your gaffer will find you.

The mounting problem

Once the device is behind the glass it is unreachable. This is true of every beam-splitter rig ever made and it is the single most annoying thing about them.

Pair a phone as a remote and you get transport, speed, and section jumps from across the room. If you are shooting alone this is not optional, it is what turns a rig from a nuisance into a tool.

Frequently asked questions

What size device fits the Desview T3?

Up to roughly seven inches, which covers all modern phones including the largest ones, and some small tablets. Measure yours before ordering.

What app should I use?

Any teleprompter with mirror mode. ScrollCue runs in the browser, is free, and needs no install.

Why is my text backwards?

Mirror mode is off. The glass flips the text, so the display has to show it pre-flipped.

How do I change the speed once it is mounted?

Pair a phone as a remote. You cannot reach the device behind the glass, which is true of every rig of this type.
