P2.5 and P3 are the two most-ordered indoor LED display pitches, and the choice between them is purely geometric: how far away is your closest viewer? Everything else — brightness, refresh rate, lifespan — is the same on both at GTECH.
A "P2.5" screen has LED dots spaced 2.5 mm apart; a "P3" screen has them 3 mm apart. That small difference changes how many LED dots each square meter carries — and the pixel count is what you actually pay for.
| Specification | P2.5 | P3 |
|---|---|---|
| Pixel pitch | 2.5 mm | 3 mm |
| Pixel density | 160,000 dots per m² | 111,111 dots per m² |
| Minimum viewing distance | 2.5 m | 3 m |
| Brightness | >1,200 nit | >1,200 nit |
| Refresh rate | ≥3,840 Hz | ≥3,840 Hz |
| Price position | Higher in the range | Lower in the range |
The P2.5 packs 44% more LED dots per square meter than the P3, which is why it sits higher in the price range. Both are true flat-panel video walls with the same brightness, refresh rate and 5-year warranty at GTECH.
The rule behind this: the human eye stops telling individual pixels apart at roughly 1 meter of distance per millimeter of pixel pitch. Closer than that, the pixel grid becomes visible; farther away, the extra pixels of a finer pitch are wasted money.
Typical P2.5 projects: conference and board rooms, control rooms, broadcast studios with close-up cameras, retail feature walls and lobby screens where people walk right up to the display. The 160,000 dots per m² keep text, data dashboards and 4K video crisp even at arm's length.
Typical P3 projects: churches, lecture halls, showrooms, mall media walls and corporate lobbies with a standing or seated audience 3 m and beyond. The eye cannot see the difference from that distance, so the budget saved on pixel density can go into a larger screen area instead — which usually impresses more than a finer pitch.
Identical on both pitches in the GTECH indoor fixed series: over 1,200 nit brightness and a 3,840 Hz or higher refresh rate, which keeps screens flicker-free in front of TV and event cameras. The P2.5 vs P3 decision never trades image stability — only resolution per square meter.
What buyers ask when they are weighing P2.5 against P3 for an indoor LED wall.
Measure first. If the front row sits closer than 3 m from the screen, P2.5. If everyone sits 3 m or farther, P3 delivers the same visual result for a lower cost per m².
No. Beyond its 2.5 m minimum viewing distance the extra pixel density is invisible to the eye. Paying for pixels the audience cannot see is wasted budget; pay for screen size instead.
No. Different pitches use different module sizes and resolutions. One screen surface should carry a single pitch so the picture stays uniform.
It carries 160,000 LED dots per m² against 111,111 for P3 — 44% more LED beads, driving ICs and power per square meter.
