The challenge
What usually goes wrong on this kind of project, and why it is worth specifying around.
A screen that vanishes at kickoff
Indoor brightness outdoors is unreadable in the hours matches are played.
An afternoon fixture puts direct sun across the stands and onto the screen. A display specified at indoor brightness simply disappears — not dimmed, genuinely unreadable — for the part of the day when most matches are played. It is the single most common and most expensive specification error in outdoor sport.
Scan lines and flicker on broadcast
Low refresh looks fine in the stand and broken on television.
Cameras sample the screen faster than the eye does. If the refresh rate is too low, the broadcast picks up rolling dark bands across the screen and the perimeter boards strobe, which makes the footage unusable and puts your sponsors' inventory on television looking broken. The screen can look perfectly fine in the stadium and still fail on camera.
Monsoon, dust and what they do to a joint
Front-only sealing lets driven rain corrode the connectors behind.
Nepal's monsoon drives water horizontally, and the dry season fills everything with dust. A cabinet rated only on the front, or sealed with a gasket that has not been specified for UV, will admit moisture at the joints within a season or two. Corrosion at the connectors is what kills outdoor screens here, not the diodes.
Player safety and impact at pitch level
Rigid boards at the touchline are an injury and a liability problem.
Perimeter boards sit exactly where players collide with them at speed. A rigid board with hard edges is a genuine injury risk and a liability question, and one impact can take out a run of cabinets in the middle of a broadcast fixture.
How we specify around it
The decisions that separate a display that still works in year three from one that merely looked good on the quote.
7,000–10,000 nits, with automatic dimming
Saturated in afternoon sun, dimmed automatically after dark.
Enough output to stay saturated in direct afternoon sun, paired with an ambient light sensor that pulls brightness down as the light drops. That second part matters as much as the first: running an outdoor screen at full output after dark wastes power and produces glare that annoys the crowd and blows out the broadcast exposure.
3,840 Hz refresh and 15-bit grayscale
It films cleanly — which is what makes perimeter boards sellable.
High refresh eliminates the scan lines and flicker a camera would otherwise pick up, so the screen films cleanly at normal shutter speeds and slow-motion replay still holds together. This is what makes perimeter boards a sellable broadcast asset rather than just something the crowd can see.
IP65 front and rear
Sealed on both faces and drained for driven rain.
Sealed on both faces, not just the visible one, with UV-stable gaskets and drainage designed for driven rain. That is the specification that survives a Kathmandu monsoon rather than merely surviving a factory water test.
Soft-mask perimeter with front access
Absorbs impact, and swaps from the pitch side between fixtures.
Impact-absorbing masks and a raked profile reduce injury risk at the touchline, and front-serviceable cabinets mean a damaged module is replaced from the pitch side between fixtures without dismantling the run or working from behind the boards.

How we scope and deliver it
Seven stages, all handled by our own team. Nothing is subcontracted, which is why we can commit to the timeline at the point of quoting.
- 01
Site assessment
We come to the site and measure it — viewing distances, ambient light, sightlines, wall or ground conditions, and where the power and data will run. Free, and it is what makes the rest of the quote real rather than estimated.
- 02
Structural design
Mounting is engineered alongside the display, not after it. Steel structures are fabricated to suit the site, which for outdoor work means wind loading and foundations as much as the screen itself.
- 03
Specification & quotation
Pitch, size, brightness and IP rating chosen for how the screen will actually be used, then quoted as a complete system — panels, processing, structure, cabling and commissioning — so nothing surfaces later as an extra.
- 04
Supply
Genuine Unilumin product with CE and RoHS certification and full manufacturer authorisation — the documentation set government tenders require, which we hold from previous work.
- 05
Installation
Our own technical team, never subcontracted. A standard indoor or outdoor install between 2×1.5 m and 4×2.5 m takes two to three days including the mounting structure; spans over 6 m or awkward mounting typically run five to seven.
- 06
Commissioning & CMS
Point-by-point calibration, brightness and scheduling configured for the site, and the content management system set up so your team can change what plays without calling anyone.
- 07
Training & support
We train your staff on the system before we leave, then back it with a two-year warranty and spare modules held in Kathmandu — so a fault is a visit, not an import.
FAQ
What brightness does an outdoor stadium screen actually need?
6,000 nits is the realistic floor for a screen facing daylight; 8,000–10,000 gives you headroom for direct sun on the screen face. Anything specified at indoor levels will be unreadable during afternoon fixtures, and no amount of processing recovers it.
Why does refresh rate matter if it looks fine to the eye?
Because the camera is the customer. Below roughly 3,840 Hz, broadcast cameras capture horizontal banding and flicker that the eye never sees, which devalues every second of sponsor exposure your perimeter boards generate.
What pixel pitch for perimeter versus a main screen?
Perimeter boards are viewed from tens of metres by the crowd but close-up by pitch-side cameras, so P2.5–P4 is typical. A main screen viewed from across the bowl can go much coarser — P6–P10 — because the viewing distance does the work.
Can the screens pay for themselves?
That is the normal model for perimeter and ribbon: they are sold as timed sponsorship inventory across a season. The commercial case usually rests on rotation rate and broadcast minutes rather than on the screen area itself.
How does it hold up through monsoon?
IP65 front and rear with UV-stable sealing and designed drainage is the specification that matters. Ask any supplier specifically whether the rating applies to both faces — a front-only rating is common and is not sufficient here.
What happens if a player runs into the boards?
Soft masking absorbs the impact and the raked profile deflects rather than blocks. Modules are front-serviceable, so a damaged section is swapped from the pitch side rather than requiring access behind the run.
