Everything the job demands

Five professional-grade calculators in one tool. The calculations that used to live in spreadsheets and people's heads — codified correctly, every time.

Port Capacity Calculator

Exact pixel load per output port with both 575K and 655K figures. Defaults to the industry-recommended safe value — no guesswork.

Novastar · Brompton

Power Chain Calculator

NEC 80% continuous load rule applied automatically. USA, UK/EU, and AUS/NZ country standards with circuit ratings pre-loaded.

NEC · IEC · AS/NZS

Resolution & Dimension Tool

Input target pixel resolution or physical size — the tool calculates both directions. Get exact cabinet grid counts and wall dimensions instantly.

Bidirectional

Viewing Distance Calculator

Minimum, optimum, and maximum viewing distances. Industry 1:1 viewing distance rule applied automatically, with pass/fail check against your actual room depth.

1:1 Rule

PDF Technician Document

Full as-built spec sheet: wall summary, port wiring map, power chain layout, cable schedule, and spare parts list. A4 or Letter. Your branding, not ours.

8 Sections

Cabinet Grid Visualiser

2D port-coloured cabinet grid showing exactly which cabinets each output port drives. Colour-coded to match your processor's screen connection layout.

Per-port colour coding

Who it's for

Built for both sides
of every job

Same tool, two workflows. From pre-sales design through to on-site documentation.

AV Integrators & System Designers

Design phase,
done right.

Stop relying on spreadsheets and rough mental maths during pre-sales. Get to the right specification faster, with confidence the numbers are correct before you quote.

Size a wall against any room or resolution budget
Calculate total power draw before you quote
Generate a professional spec document in minutes
Compare panel and processor combinations instantly

LED Technicians & Installers

On site, fully
documented.

The information that used to live in your head or get lost between planning and installation now travels with the job as a professional document.

Open saved plans on your phone on site
Know exactly which port drives which cabinet
Power chain layout and circuit map at a glance
Spare parts count and part numbers calculated automatically

How it works

From spec to document
in six steps

Select your hardware

Pick your panel and processor from the built-in library. All specifications pre-loaded — no manual data entry required.

Configure your wall

Enter target dimensions or pixel resolution. Set your country for power standards. Port assignments, power chains, and viewing distances calculate in real time.

Export and deploy

Download a complete PDF technician document. Save your project as a .ledvis file. Open it on site from any device — no internet connection required.
