Pixel pitch is the single most important spec on an LED video wall — it sets viewing distance, image solidity, native resolution, brightness budget, and price per square metre. This guide is the long-form reference our engineers use when sizing a wall: what each common pitch is for, how to choose between them, and — critically — which Dynamo product line is the right fit for each use case. Use the configurator if you want the answer in three minutes; use this page if you want to understand the trade-offs first.

What is pixel pitch?

Pixel pitch is the centre-to-centre distance between adjacent LED pixels on a direct view LED wall, expressed in millimetres. A “P2.5” wall has 2.5mm between pixels; a “P1.5” wall has 1.58mm. The smaller the pitch, the higher the pixel density, the closer viewers can sit before the pixel grid becomes visible, and — at the same screen area — the higher the capex.

Pixel pitch matters more than any other spec because it sets a hard floor on viewing distance and a hard ceiling on resolution for any given physical wall size. Choose the pitch wrong and you either pay for density viewers can’t see, or you build a wall whose pixel grid is visible from every seat in the room.

The viewing distance rule of thumb

The working rule our engineers use to size pitch against context: one metre of viewer distance per millimetre of pitch. P1.5 → 1.5 m minimum comfortable viewing distance. P2.5 → 2.5 m. P3 → 3 m. P6 → 6 m. Below that minimum the pixel structure becomes visible to a viewer with normal vision; above it the wall reads as a single image.

This isn’t an aesthetic preference — it’s a function of human visual acuity. At 20/20 vision the eye resolves about 1 arc-minute, which for a viewer 2.5 m from a P2.5 wall puts adjacent pixels right at the edge of distinguishability. Closer and you start to see grid; further and you can’t.

Choose by use case — the decision tree

Pitch alone doesn’t tell you which product to buy. The right Dynamo product depends on how the wall will be used — most buyers are looking for a permanent install, and the permanent-install products (DFC and DX) are different from the rental-install products (DRE) even at the same pitch class.

Use case	Pitch range	Right Dynamo product	Why
Premium fixed install Boardroom, broadcast studio, control room, premium retail flagship, broadcast green room	P1.5 and below (sub-1.9mm)	DFC Series (Flip Chip COB) DFC 1.5, DFC 1.9	Flat front, deep blacks, broadcast-grade, COB impact-resistance, ~50% lower power than SMD
Mid-range fixed install Corporate lobby, retail, hospitality, meeting room, hospitality signage, atrium	P1.9 to P5.9	DX Series DX1.9, DX2.5, DX2.6, DX2.9, DX3.1, DX3.9, DX5.9 + DX HB for high-brightness windows	SMD on die-cast aluminium, front-serviceable, modular cabinets, seamless right-angle install
Exhibition, rental, stage, temporary outdoor Trade shows, event keynotes, festival stages, broadcast pop-ups	P1.55 to P3.875	DRE Series DRE P1.55, P1.93, P2.58, P2.95, P3.875	IP-rated cabinets built to ship, rig and de-rig repeatedly. Not built for permanent install.
Outdoor permanent install Billboards, building facades, large-format outdoor signage	P3 outdoor and above	DVO Series DVO P6, P8, P16	IP65 front, 6,000–8,000+ nits, weather-sealed, sized for distance viewing
Flexible LED mesh / curved facade Retail windows, building wraps, stage backdrops, architectural facades	Mesh-class, varies	L-V-W FlexCurtain (see also FlexCurve for fixed radius)	Flexible LED mesh — different product family from rigid cabinet builds

The single most common misclassification we correct: buyers assume rental and permanent install are the same product at the same pitch. They aren’t. DRE is built for ship/rig/de-rig and has IP rating; DFC and DX are built for permanent install and are easier to commission, lower TCO, and not designed for transport. If the wall will live in one place for years, you want DFC or DX. If it ships to a different venue every fortnight, you want DRE.

P0.9 — ultra-fine pitch

Dynamo product: DYF 0.93 (Flip Chip COB, premium indoor)

Sub-1mm pitch — the territory of control rooms with operators within touching distance of the wall, broadcast scenic where talent leans on the screen, XR/virtual production stages, and any context where a viewer might literally place their hand on the surface. Pixel density is over 1.1 million per square metre; the wall reads as a single image at any viewing distance.

Capex per square metre is the highest in the indoor range. DYF 0.93 (5.6 kg per single cabinet, 1,200 nits, 4,320 Hz refresh, 600 × 337.5 mm cabinet) is built for the contexts that justify it: high-end studios, XR stages, NOC walls where operators sit at the bench.

P1.2 — sub-1.5mm fine pitch

Dynamo product: DYF 1.25 (Flip Chip COB, premium indoor)

Between sub-1mm pixel-density and the more mainstream P1.5/P1.9 range. P1.2 lets viewers sit ~1.2 m from the wall with no visible pixel grid — the right pitch for very small control rooms, broadcast presenter consoles, executive briefing tables where the wall is at arm’s length. DYF 1.25 delivers 2,400 nits brightness (high for fine-pitch — useful for window-adjacent boardrooms with daylight bleed) on the same COB Flip Chip build as DYF 0.93.

P1.5 — premium fixed-install fine pitch

Dynamo product: DFC 1.5 (Flip Chip COB, premium fixed install)

The mainstream pitch for premium fixed-install dvLED. Viewing distance 1–1.5 m, ~400,000 pixels per square metre, Full HD in a 3 × 1.69 m wall, 4K in a 6 × 3.375 m wall. DFC 1.5 (Flip Chip COB, 37 mm cabinet depth, dual-backup power and receiving cards, ~50% lower power draw than SMD at the same brightness) is the right product for boardroom tables, broadcast presenter desks, control rooms with operators at the bench, video conferencing rooms with remote attendees on Zoom or Teams, and premium retail flagships where customers stand within touching distance of the screen.

Full breakdown, spec table and use-case detail on the standalone P1.5 product page.

Rental equivalent: for exhibition stands and stage builds at this pitch class, our DRE P1.55 rental cabinet is the right product — IP-rated and built to ship.

P1.87 / P1.9 — premium-mid crossover

Dynamo products: DFC 1.9 (Flip Chip COB, premium) or DX 1.9 (SMD, mid-range)

Sits between premium fine-pitch (P1.5) and mid-range commercial (P2.5). Viewing distance ~1.9 m. The choice of product line depends on the context, not just the pitch:

• DFC 1.9 — Flip Chip COB. Use for broadcast green rooms, premium briefing centres, slightly larger boardrooms where the COB aesthetic and TCO still matter.
• DX 1.9 — SMD1515 on the modular DX chassis. Use for corporate lobbies, retail signage and hospitality where the install context doesn’t justify the COB premium.

Rental equivalent: DRE P1.93 for ship/rig builds at this pitch class.

P2.5 — mid-range commercial workhorse

Dynamo product: DX 2.5 or DX 2.6 (SMD1515/2020, indoor fixed install). For high-brightness windows: DX HB 2.9.

The volume pitch for commercial dvLED. Viewing distance 2.5 m, 160,000 pixels per square metre, Full HD in a 4.8 × 2.7 m wall, 4K in a 9.6 × 5.4 m wall. DX 2.5 (250 × 250 mm modules, 8.5 kg/cabinet, ≥800 cd/m², 3,840 Hz refresh, 14-bit grey scale, housing-free direct-PCB modules) is the default spec for corporate lobbies, retail flagships, mid-size boardrooms, hospitality lobbies, atria, conference centres, fitness and yoga studios, mid-range broadcast studios.

DX 2.6 is a lighter cabinet variant (6.5 kg vs 8.5 kg) — matters for flown/rigged builds and reduces structural load on suspended ceilings. DX HB 2.9 (≥3,000 cd/m² on SMD1921) is the right spec when the wall sits in a shop window, sun-flooded atrium or transport hub where standard 800-nit brightness washes out.

Full breakdown, spec table and 5-year TCO snapshot on the standalone P2.5 product page.

Rental equivalent: DRE P2.58 for exhibition and stage builds.

P3 — mid-range fixed install for larger walls

Dynamo product: DX 3.1 (SMD2020, indoor fixed install)

P3 is where commercial economics tilt firmly toward larger walls. Viewing distance 3 m, ~111,000 pixels per square metre, Full HD in a 5.76 × 3.24 m wall, 4K in a 11.5 × 6.5 m wall. DX 3.1 (250 × 250 mm modules, 3.5 kg/cabinet — very light, ≥800 cd/m², 3,840 Hz refresh on SMD2020) is the right spec for large corporate lobbies, public venues at distance, conference set backdrops, signage at concourse distance, atria above 4 m wide, and any context where viewers are seated or standing 3 m or further from the wall.

Compared to P2.5 at the same wall size, P3 saves materially on capex per square metre — typically 25–35% lower — because cabinet count is the same but module pixel count drops. At 3+ metres of viewer distance there’s no visible image quality difference. The decision should always be made on viewing distance, not on perceived “premium-ness”.

Typical P3 use cases:

• Large corporate lobby feature walls (5 × 3 m+)
• Conference centre keynote stage backdrops (8 × 4.5 m)
• Public venue signage (museum lobbies, concourses, transport interchange)
• Worship venues — IMAG screens at the back of the room for congregations of 200+
• Live event and conference set builds (often as a DRE rental at P2.95 instead)
• Atrium video walls at building scale

For high-brightness window or daylit-atrium contexts at this pitch class, DX HB 3.9 (≥3,000 cd/m²) is the right step — the small pitch increase from 3.1 to 3.9 mm is invisible at 3+ m viewing distance, while the brightness uplift makes the wall usable in direct sun.

Rental equivalent: DRE P2.95 (slightly finer than DX 3.1, IP-rated, built for stage shows).

P4 — large-format indoor and outdoor-budget

Dynamo product: DX 3.9 (indoor) or DRX 3.9 (indoor/outdoor MicroX)

P4 is the natural pitch for very large indoor walls where viewers are 4 m or further away, and the budget tier for outdoor builds where viewers are at street or concourse distance. Viewing distance 4 m, ~62,500 pixels per square metre, Full HD in a 7.7 × 4.3 m wall, 4K at 15.4 × 8.7 m.

Typical P4 use cases:

• Concourse and transport-hub signage (high-throughput viewer flow, varying distance)
• Worship venues — large IMAG walls for congregations of 500+
• Stadium concourse displays
• Conference centre breakout signage
• Outdoor permanent signage at near-street distance (IP-rated outdoor variant required)

P4 is often the wrong pitch for buyers who land on it from a generic search — many P4 enquiries genuinely want P2.5 or P3 once viewing distance is properly understood. Always work backwards from where the closest viewer will be; the configurator runs this calculation automatically.

Rental equivalent: DRE P3.875 for stage/event builds in this pitch class.

P6 — outdoor permanent install

Dynamo product: DVO P6 (outdoor, IP65)

P6 is the start of the outdoor large-format range. Viewing distance ~6 m, 27,777 pixels per square metre, 6,000–8,000 cd/m² brightness for daylight readability, IP65 front and IP54 rear weather sealing. DVO P6 (960 × 960 mm cabinets, 25 kg/m², SMD2727, dual signal, built-in PSU) is sized for outdoor permanent installs — building facades, retail forecourt signage, transport hub external displays, commercial advertising at urban-distance scale.

For longer viewing distances or larger billboards, step up to DVO P8 or DVO P16 — the same chassis at coarser pitch, same brightness, lower cost per square metre.

Quick-reference table — pitch to product to use case

Pitch	Permanent install (fixed)	Rental (ship/rig)	Viewing distance	Typical use
P0.9	DYF 0.93	—	~0.9 m	XR stage, broadcast scenic, NOC console
P1.2	DYF 1.25	—	~1.2 m	Broadcast console, briefing table, micro control room
P1.5	DFC 1.5	DRE P1.55	~1.5 m	Boardroom, broadcast studio, control room, premium retail

P6+	DVO P6	DTEK / DRE outdoor	~6 m+	Outdoor billboard, building facade, forecourt

Pitch and resolution — common wall sizes

The native resolution of a dvLED wall is fixed by pitch and physical size. To hit a target resolution (HD, UHD/4K), pick the pitch that lands the right wall size for the room:

Target resolution	P1.5	P2.5	P3	P4
Full HD (1920×1080)	3.04 × 1.71 m	4.80 × 2.70 m	5.76 × 3.24 m	7.68 × 4.32 m
UHD / 4K (3840×2160)	6.07 × 3.41 m	9.60 × 5.40 m	11.52 × 6.48 m	15.36 × 8.64 m

4K resolution at a 4 × 2 m wall is only achievable at sub-2mm pitch — DFC 1.5 in practice. For larger 4K walls (5 × 3 m+) P2.5 or P3 is the right pitch. The configurator runs the maths automatically based on room dimensions and resolution target.

Price-tier framing — what each pitch costs commercially

dvLED pricing scales with pixel density and product line. Indicative tiers (UK commercial, fully installed, indoor):

• P0.9 / P1.2 (DYF Series) — premium-premium. The most expensive indoor tier per square metre. Used where the context demands it.
• P1.5 / P1.9 (DFC Series) — premium. COB premium over equivalent SMD product. Justified for broadcast, boardroom, control room, premium retail.
• P2.5 / P2.6 (DX Series) — mid-range. The volume tier. Best price-per-square-metre for commercial-quality dvLED above 4 m².
• P3 / P4 (DX Series, larger pitches) — budget for larger walls. 25–35% lower per m² than P2.5 at the same screen area. Right for viewing distances 3 m+.
• P6+ (DVO Series, outdoor) — outdoor permanent. Pricing reflects IP rating, high brightness, weather sealing and outdoor structural certification.

Capex isn’t the only number that matters. Run-cost (power draw, service contract, replacement modules over 5 years) typically adds 15–25% to the 5-year cost of the wall, and varies significantly by product line. DFC’s ~50% lower power draw than equivalent SMD at the same brightness is a real TCO advantage at large wall sizes.

Common mistakes when choosing pitch

• Choosing pitch by budget rather than viewing distance. If viewers sit 1.5 m from a P3 wall, they see the pixel grid every day. Save the money on something else, not on pitch.
• Choosing pitch on perceived “premium-ness”. P1.5 in an atrium where viewers are 8 m away is wasted density. P2.5 or P3 looks identical at that distance for materially less money.
• Confusing rental and permanent product lines. DRE is built for ship/rig. DFC and DX are built for permanent install. Same pitch, different product, different price, different commissioning workflow.
• Ignoring ambient light. 800 nits is correct for indoor commercial. Shop windows, atria with skylights, transport hubs need high-brightness (DX HB at ≥3,000 nits) or outdoor (DVO at 6,000+ nits).
• Buying 4K capability for an HD source. If the content pipeline runs Full HD, a 4K-native wall doesn’t deliver 4K — it upscales. Spec pitch and size against actual source resolution.
