Tech Specs & Compatibility
Your laptop.
Four screens. One cable.
Three extra displays that attach to your laptop lid. Left, right, and a top screen no other dual extender has. One USB-C cable powers all of them.
Left. Right.
And one above.
When everything is on the same level, something always gets buried. The Slack message behind the spreadsheet. The alert hiding behind the browser. The top screen fixes this: put your calendar, alerts, or team chat above your work so it stays in your peripheral vision without stealing focus. Nothing buried. Nothing missed.
And when you need to show someone your screen, flip it 180 degrees toward them. The display automatically rotates so they see it right-side up — no manual adjustment, no settings to change. No spinning your laptop. They see what you want them to see while you keep working.
The entry you miss
because you're in the wrong tab.
You stop missing it.
The position moves while you're checking something else. You get back to TradingView and the entry already happened. You were watching. Just not that screen.
Robinhood on the left. TradingView in the center. Live market feed on the right. Alerts on the top screen. Your entire information stack visible at once. When the market moves, you see it. When an alert fires, it fires into a screen you're already looking at. That is the difference between reacting and executing.
The tab you close
by accident.
Stop closing it.
You read the docs. Switch back to the editor. Already forgot the function signature. Switch back. The terminal output scrolled off. The cycle repeats until focus collapses.
Docs on the left. VS Code in the center. Terminal on the right. Stack Overflow or team chat on top. Everything visible at once. You stop losing your place because there's no place to lose. The work you care about never gets buried behind a notification again.
Timeline. Assets. Preview.
All visible. All the time.
Your timeline is on screen. Your assets are buried in a folder. Your preview is squeezed into a corner. You're editing in the margins of your own project.
Timeline on the left. Premiere or Final Cut in the center. Asset browser on the right. Reference or client notes on top. Every tool at full size, in position, for the entire edit. Designers get the same clarity: Figma in the center, client brief on the left, component library on the right, feedback or specs on top. You stop reorganizing and start finishing.
Stop switching tabs
to make a decision.
Revenue is down. You open three tabs to understand why. By the time you have the context, the urgency has softened and you move on without acting.
ChatGPT on the left. Shopify in the center. Upwork on the right. Meta Ads Manager on top. The revenue drop, the campaign behind it, the freelancer who can fix it. All visible before you finish your coffee. Context and decision in the same moment.
11% more screen.
Every hour you work.
On a standard 16:9 monitor you see 45 lines of code before you scroll. On a TrueView 16:10 display you see 50. Three more spreadsheet rows. More chart history without zooming out. That 11% compounds across every task, all day, every day.
The Lumis Trio uses 1920x1200 FHD+ panels, not 1920x1080 like most portable monitors. Up to 100% sRGB color accuracy. 270 to 300 nits brightness, measured not peak. Text stays at comfortable reading sizes. You stop rescaling windows and start actually reading them.
All three models use 16:10 TrueView panels at 1920x1200.
Not all extenders
are equal.
We built the Lumis Trio after seeing the same problems across this entire category. Inflated specs, hidden shipping fees, and returns that never get processed.

One cable.
Three screens on.
On Windows, drivers install automatically when your laptop is online. Plug in and work. No downloads, no restarts, no configuration. On macOS, one install from the included USB drive takes two minutes. Every connection after that is plug-and-play.
The included 30W PD adapter powers all three screens and charges your laptop simultaneously, and any 30W+ power bank does the same, so your setup runs fully untethered without a wall outlet. Six physical brightness buttons on the frame let you adjust each screen independently without touching your laptop.
Works with the laptop
you already own.
Base-model MacBook? Works. The Lumis Trio bypasses Apple's single-display limitation on M1, M2, M3, and M4 chips. All three screens through one cable, no workarounds needed.
The expandable frame fits laptops from 12" to 18.5" with lids up to 8mm thick. Clamps securely without marking the lid. The integrated back stand distributes weight across the frame, not onto your hinge.
Three screens.
Folds flat.
Opening it feels like unfolding a workstation. Closing it feels like closing a laptop. The three screens collapse into a single rigid form. No panels to separate, no pieces to keep track of, nothing to reassemble at the other end of the flight. Slides into the included carry case as a complete unit. You stop choosing between a proper setup and the ability to move.
Six ways to work.
One device.
The 360 degree hinge system plus the flipping top screen give the Lumis Trio configurations no other portable extender can match.
Panoramic Workspace
Your full four-screen setup. Everything open, nothing hidden. The work you used to do across three desktops happens on one.
Top Screen Flip
Rotate the top screen 180 degrees toward the person across the table. You keep typing. They see exactly what you want them to see.
Portrait Mode
Rotate the side screens vertical and see 80 lines of code instead of 45, full documents without scrolling, and longer spreadsheets in a single view.
Meeting Mode
Fold into a triangle and two screens face in opposite directions. Two people, two screens, no one craning their neck. The meeting starts faster.
Built-in Kickstand
Unfold the kickstand and the screens stand on their own desk. No laptop needed. A stable, independent triple-monitor setup on any surface.
Standalone Monitor
Detach from your laptop and use one, two, or all three panels as independent external displays. The same screens, a completely different setup.
Your full setup.
In the bag you already carry.
The moment you leave a monitor at home, you lose the setup that makes you fast. Hotel rooms become single-screen days. Client offices mean working cramped. The Lumis Trio removes that trade-off. Fold it, slide it into the included carry case, and your full four-screen workstation comes with you. You work at full capacity everywhere, not just at your desk.
Open the box.
Start working.
No separate purchase for the power adapter. No carry case sold as an optional add-on. No hunting for a compatible cable because yours is the wrong length. Everything you need to set up, use, and travel with the Lumis Trio ships in the box on day one.
No hidden costs. The power adapter, carry case, and all cables ship in the box.
Two sizes.
Same TrueView quality.
The 14" is built for maximum portability. The 16" is built for maximum workspace.
