GVM teleprompter — the app to run on it.
GVM sit at the larger end, taking a full-size tablet rather than a phone. Which changes what your settings should be.

In short
GVM beam-splitter teleprompter rigs accept full-size tablets. They work with any teleprompter software with mirror mode, including ScrollCue, which is free, runs in a browser, and needs no app download.
A bigger screen changes the maths
Most consumer rigs are built around a phone. GVM's larger models take a proper tablet, and that is a meaningfully different reading experience. You have room, which means you can do the thing that actually matters for eye contact: narrow the column.
On a phone you cannot. The screen is already narrow and squeezing it further just wastes it. On a tablet, dropping the column to around 55 to 60% means each line holds five to eight words and your eyes barely move sideways at all. That side-to-side scan is the movement viewers register as reading, and this is the setting that kills it.
Settings
Mirror mode on
Beam-splitter, so the glass flips the text. Always.
Font 60 to 72 px
You have the room. Use it. Bigger text through glass is more legible than small high-contrast text, which is not obvious until you compare them.
Column 55 to 60%
The whole reason to have a tablet-sized rig. Short lines, minimal eye travel.
Cue line slightly higher than feels natural
Most people set it too low and end up reading with their eyes angled down. Nudge it up.
Remote control matters more on a big rig
A tablet under a large shroud is genuinely unreachable, and these rigs are heavy enough that you do not want to be disturbing the mount to adjust a setting. Pair a phone. Speed, transport, section jumps, all from where you are standing.
If someone else is running the shoot, they can drive the whole thing and you never touch a control at all, which is what a rig this size is really for.
Frequently asked questions
What app should I use with a GVM teleprompter?
Any teleprompter with mirror mode. ScrollCue is free, browser-based, and works with any brand of rig.
What settings for a tablet-sized rig?
Font 60 to 72 px and column narrowed to around 55 to 60%. The narrow column is the real benefit of having a bigger screen.
Why narrow the column on a big screen?
Short lines mean your eyes barely travel left to right. That sideways scan is what viewers register as reading, and a narrow column removes it.
How do I control it once the tablet is mounted?
Pair a phone as a remote. A tablet under a large shroud cannot be reached, and disturbing the mount mid-shoot is worse than not adjusting anything.
