When you hire an LED screen you'll hear terms like "P3" or "P4" and "indoor" or "outdoor". It sounds technical, but the idea is simple — and knowing it helps you pick the right screen.
What pixel pitch means
Pixel pitch is the distance between the tiny LEDs, measured in millimetres. A P3 screen has 3mm between pixels; a P4 has 4mm. Smaller numbers mean more pixels packed in, so the image is sharper up close. Bigger numbers are fine when the audience is further away.
Match it to viewing distance
If people stand close — a stage backdrop, an exhibition booth — a smaller pitch (P2–P3) looks crisp. For a big outdoor crowd standing far back, a larger pitch (P4 and up) works well and costs less, because the distance hides the gaps.
Indoor vs outdoor screens
Outdoor screens are brighter to fight daylight and are weather-sealed; indoor screens are finer and made for controlled lighting. Using the right type matters — an indoor screen outdoors will look dim and risks water damage.
Don’t overthink it
You don't need to memorise any of this. Tell JMG Audio your venue, audience size and how close people will be, and we'll recommend the right screen size and type.
Frequently asked questions
What does P3 or P4 mean on an LED screen?
It is the pixel pitch — the distance in millimetres between the LEDs. P3 (3mm) is sharper up close; P4 and above suit audiences standing further away and cost less.
What size LED screen do I need?
It depends on your venue, audience size and how close people stand. Share those details with JMG Audio and we will recommend the right screen size and type.
