A 3m × 2m P3.91 Outdoor LED Video Wall: What You Get
A customer looking at a P3.91 outdoor video wall — 3,840 Hz refresh, 4,000 nits — told us they would be looking for a 3m × 2m size. That is a very common, very buildable outdoor spec, so here is exactly what a 3m × 2m P3.91 wall gives you and why those numbers (pitch, refresh, brightness) are the right ones to check.
It is a great example of how a standard panel scales cleanly to a custom size.
How a 3m × 2m P3.91 wall is built
P3.91 outdoor panels are commonly 500 × 500 mm cabinets, so a 3m × 2m wall is a clean 6-wide × 4-high grid — 24 cabinets — with no awkward part-panels. At P3.91 that gives roughly 768 × 512 pixels across the whole 6 m² wall: plenty for video, graphics and large text viewed from a few metres back, which is the typical outdoor distance.
- Size — 3000 × 2000 mm (6 m²).
- Cabinets — 24 × 500 mm modules (6 × 4 grid).
- Resolution — ~768 × 512 px at P3.91.
- Format — landscape 3:2, ideal for mixed video and promo content.
Why 4,000+ nits matters outdoors
Brightness is the make-or-break spec outdoors. A normal indoor screen (~500 nits) is invisible in daylight; an outdoor wall needs around 4,000–6,000 nits to stay punchy in direct sun, with an auto-brightness sensor to dim at night and save power. 4,000 nits is a solid outdoor figure; if the wall faces full midday sun, we may suggest a touch higher.
Why 3,840 Hz refresh is worth having
A high 3,840 Hz refresh rate keeps the image flicker-free to the eye and, crucially, on camera. If the wall will ever appear in video — a broadcast, a live stream, social clips of your event — a high refresh rate stops the dark scan-lines that low-refresh screens show when filmed. For an advertising or event wall it is well worth specifying.
P3.91 vs P4 outdoors — which to pick
P3.91 and P4 are very close in pitch and often the same product family; P3.91 is the slightly finer, slightly sharper option and is the popular outdoor rental/advertising choice. For a 3m × 2m wall viewed from roughly 4 m or more, both look excellent — P3.91 gives a little more detail for closer viewers, while a coarser pitch would save cost where everyone stands well back. Tell us the closest viewing distance and we confirm the best-value pitch.
| Spec | What it means | |
|---|---|---|
| Pixel pitch | P3.91 | Sharp from ~4 m; popular outdoor choice |
| Size / cabinets | 3 × 2 m / 24 | Clean 6 × 4 grid of 500 mm panels |
| Resolution | ~768 × 512 px | Ample for video and large text |
| Brightness | 4,000+ nits | Readable in direct sun, auto-dim at night |
| Refresh | 3,840 Hz | Flicker-free to the eye and on camera |

Frequently Asked Questions
How many panels make a 3m × 2m P3.91 wall?
With 500 mm cabinets it is a 6 × 4 grid — 24 cabinets — for a clean 3000 × 2000 mm wall with no part-panels.
What resolution is a 3m × 2m P3.91 screen?
About 768 × 512 pixels across the whole wall — plenty for outdoor video, graphics and large text at typical viewing distances.
Is 4,000 nits bright enough for outdoors?
Yes for most outdoor placements; it stays readable in direct sun and dims automatically at night. For full midday-sun walls we may suggest a little higher.
Why does 3,840 Hz refresh matter?
It keeps the wall flicker-free to the eye and on camera, so it looks clean in any video, broadcast or live stream — important for advertising and events.
Should I choose P3.91 or P4 outdoors?
They are close; P3.91 is slightly sharper and a popular outdoor choice. For viewing from ~4 m+, both look great. Send the closest viewing distance and we confirm the best-value pitch.
