Meet Mersive Polaris, matey: wireless screen sharin' from any browser.

One platform turns every display into a shared workspace fer the whole crew: joined from a browser, BYOM an' client agnostic, managed from one cloud.

The signature chart

Glass. Workspace. Cloud.

Three layers, one platform: the display renders, the workspace composites, the cloud connects an' manages. Open up any layer fer the plain-spoken depth, savvy.

How a share reaches the room, in three steps Step one, join: the laptop, the phone, the Polaris pod and a remote participant in a browser each send a short signaling ping up to Polaris Cloud and get an answer back: authenticate, resolve the screen key, exchange SDP and ICE. Step two, connect: direct links form between the endpoints and the pod, and the cloud drops out of the media path. Step three, compose: the shares land side by side on the display as one workspace, and the remote participant sees the same workspace live in the browser. THE ROOM direct {/* THE LABEL LIVES INSIDE THE ICON. On one line at 14 it measured 131 against a cloud 96 wide and ran out both sides, and it was centered on 450 where the shape's own center is 465, so it was off to the left as well. Two lines at 12 measure 59 and 42, which sit in the belly of the cloud with 18 to spare.

Layer 1 · down in the roomThe glass

Any display becomes a Polaris endpoint: meetin' room, classroom, lobby wall, aye.

＋ more

The display stops bein' a destination ye cable into an' becomes a renderin' target: the Polaris device behind it draws whatever the workspace tells it to draw.

  • Any display qualifies. The panel ye already own, driven by a Polaris device behind it: no smart-panel firmware to lean on, no vendor-matched displays.
  • In Polaris Pro rooms, the AV plugs in right here. Camera an' mic cable into the Pro device, so meetin's can borrow 'em wirelessly.
  • Idle displays still earn their keep. When no one be sharin', the same display runs signage, managed from the same portal. Signage →
Layer 2 · the unit o' workThe workspace

Every share, side by side, composited live, fed from any device, in the room or far across the water.

＋ more

The workspace be what makes the display worth lookin' at: not one mirrored screen but a composited canvas o' simultaneous sources, mirrored live to every participant signed in at app.mersive.com.

  • Multi-source, live. A deck o' slides from a laptop, a guest's browser tab, photos from a phone, a dashboard from another buildin': side by side, rearranged from the Dock.
  • Any device feeds it. Native share or web-join from the browser; sources from other networks sail in via cross-network sharin'.
  • It belongs to the room. The workspace be rendered by the room's Polaris hardware, not by whichever laptop happens to be open, so shuttin' a lid does not end the meetin'; it just removes the content from that device while everythin' else stays exactly where it was.
Layer 3 · above the whole fleetThe cloud

Routes every workspace, manages every room: one admin plane fer the whole fleet, like a captain's chart.

＋ more

Polaris Cloud does two jobs: it introduces sessions (the signalin' that lets endpoints find each other across networks) an' it runs the fleet, which be conference room management fer every room an' screen ye own.

  • Session brokerin'. Devices an' displays find each other through the cloud; same-network traffic stays on yer LAN; cross-network traffic flows over a WebRTC direct, encrypted connection the cloud negotiated.
  • Conference room management. Bulk config, templates by room type, staged firmware, analytics an' health alerts, fer meetin' rooms an' signage alike, from one login. Polaris Cloud →
  • What it doesn't do. Store yer workspace content. The candid data-path story be told in the Trust Center.

How to share yer screen from a browser

Sharin' from the browser needs no app, no downloadin', no installs an' no admin rights; ye share to the room display from a browser tab. A guest who just walked aboard can share, an' there be no client to package, approve, patch, or manage.

Four steps, zero software, savvy:

1Open ye a browser

Web-join works on any device with a current browser, Chromebooks an' locked-down loaners included. Phones share through the Mersive app or the native protocol.

→
2Sail to app.mersive.com, type the screen key

The 6-character key be on the display. Every key be globally unique an' expires ten minutes after it's issued.

→
3Ye're on the display

Yer share lands in the workspace next to everyone else's, composited live, not queued behind a presenter.

→
4The Dock sails along in the tab

Layout, participants, handoff, end meetin': the room's controls live in the same browser tab ye joined from.

✓ No client✓ No admin rights✓ Works on Chromebooks, aye
Every way aboard

Web share be the front door. It isn't the only door, mind.

The workspace takes whatever the room brings aboard. Web-join be the predominant path, but native castin' an' the Mersive mobile apps land on the same display, an' they all composite together.

Web-joinany network at all

The browser share: no install, cross-network, guest-proof. The predominant path, matey.

Polaris mobile appany network at all

Share and control from the phone in yer pocket. iOS & Android.

Wired HDMIPro only

An HDMI source joins the workspace as a tile by default, matey. Direct bypass takes the glass full screen and keeps that feed in the room.

AirPlayLAN only

Native Apple sharin': no Mersive software on the device.

MiracastLAN only

Native Windows sharin', straight from the OS.

Google CastLAN only

Chromecast from Chrome and Android: the Chromebook classroom's native passage.

All o' these: at the same time, on the same workspace. An AirPlay share, a Miracast share, a browser guest, an' a phone can sit side by side on one display. An HDMI source joins the workspace as a tile by default, matey. Direct bypass takes the glass full screen and keeps that feed in the room. Web-join an' the Mersive apps work from any network; native castin' (AirPlay, Miracast, Google Cast) be LAN-only. Native castin' reaches the room over the local link only (the room's network, a peer-to-peer Wi-Fi Direct session, or the receiver's own access point), an' discovery be link-local, so it breaks the moment a VLAN boundary heaves into view. Once its share lands in the workspace, remote participants see it like everythin' else. Web-join an' the Mersive apps join from any network. We say so plainly on the cross-network page.
Meetin' parity

Everyone sees what the display shows, all hands alike.

Meetin' parity (what remote participants see): every source shared into the room be delivered to everyone who joined at app.mersive.com, an' the layout travels with it. Order, focus, full-screen an' position stay in step, because the room an' every browser run the same layout code.

So a remote seat reproduces what the display shows at its own screen's resolution rather than watchin' a video o' the room's screen. No cranin' at the display, no “can ye re-share that,” no second-class seats.

Wired HDMI: two modes, take yer pick

Polaris Pro has two wired HDMI input modes, chosen by yer room administrator. Workspace tile be the default: the input joins the workspace alongside wireless shares and be visible to remote crewmates. Direct bypass (full-screen pass-through) sends the input straight to the room display, outside the workspace. Remote crewmates do not receive that feed.

Why the silicon matters, matey

Where a panel stops an' the room silicon takes the helm.

A workspace be a compositin' problem: a roomful o' people sharin' at once means many simultaneous decode sessions rendered into one layout, an' bridgin' yer meetin' to the room's AV adds real-time encode on top.

That takes purpose-built silicon, not a display's spare cycles, savvy.

The memory ceilin'

Around 5 simultaneous shares on Essentials an' 10 on Pro. 'Tis a memory ceilin' on the chassis, not a license: nothin' in the software counts sources or refuses one, so the limit be what the silicon can hold, an' the two tiers run the same code.

Mirroring versus recompositing Two lanes. Above: mirroring, as everyone else does it. One laptop sends its pixels one to one along a dashed line to a display, which shows the same picture at the same shape. One source, one screen, and nothing leaves the room. Below: recompositing, as Polaris does it. Four sources - a deck, a browser tab, a phone photo and a live dashboard - each reach their own decode chip, and the four feeds converge on the workspace compositor, which lays out a fresh workspace automatically as sources join and leave. The workspace leaves by two paths: rendered at the display's native resolution onto the room's glass as a four-up layout, and to every remote browser, where each seat runs the same layout code to rebuild the same workspace. MIRRORING VS RECOMPOSITING MIRRORING · EVERYONE ELSE one laptop pixels copied · 1 : 1 · nothing decides anything ✕ the display is a copy: one source, one screen, nothing leaves the room. RECOMPOSITING · POLARIS DECKBROWSER TABPHONE PHOTOLIVE DASHBOARD H.265H.264VP8H.264 4 simultaneous decodes · the ceiling is memory, not a license: 5 on Essentials, 10 on Pro as of Sep 2026 THE WORKSPACE a fresh workspace, laid out automatically as sources join and leave rendered at the display’s native resolution the same workspace in every remote browser every seat runs the same layout code ✓ the room draws a new picture: nobody’s laptop is load-bearing

What this buys ye in the room: a panel's composite stays on its own glass; Polaris encodes the whole meetin' out to every participant, an' Polaris Pro keeps enough encode headroom to hand the room's camera an' mic to yer Teams, Zoom, Webex, or Meet call.

Dive deeper

Evaluatin' Polaris? Start with these four reads, cap'n.

Cross-network sharin'

Content crosses subnets, VLANs, an' the open internet: no VPN, no UC call. O' the twelve competitors we checked in August 2026, exactly one documents a comparable off-LAN path, an' it wants two ephemeral port ranges, XMPP an' STUN/TURN/ICE, with signallin' hosted in Azure West Europe. The other eleven document LAN-local media only.
