The most common mistake in LED screen rental for exhibition stands is specifying the wrong pixel pitch for viewing distance. Most other errors come from treating the screen as a separate rental add-on instead of designing it into the stand alongside structure, power, and content from the start
Most other LED mistakes on the exhibition floor come from treating the screen as a rented add-on rather than something designed into the stand from the start, alongside structure, power, and content.
Here’s what goes wrong most often at exhibitions specifically, and what to check before booking.
1. Specifying Pixel Pitch for the Wrong Distance
Pixel pitch is the distance, in millimetres, between individual LED clusters on a panel. The smaller the number, the sharper the image at close range, and the higher the cost. On an exhibition stand, visitors regularly stand within a metre or two of a screen, sometimes closer. This is a very different viewing distance to a conference stage or festival backdrop.
- Overspending: booking a fine pitch better suited to broadcast work for a screen mounted high on a fascia, where nobody gets close enough to notice
- Underspending: booking a wider pitch to save budget for a screen at eye level near the aisle, where visitors will be standing close enough to see individual pixels on text and logos
The fix: specify pitch based on where the screen sits on the stand and how close visitors realistically get to it, not one blanket spec for the whole build. Your stand build will be able to advise and guide you based on the plan.
2. Treating the Screen as Separate From the Stand Design
LED screens are frequently booked from a separate AV supplier after the stand structure is already designed. This means nobody has checked whether the fascia, wall, or media unit was planned to carry the screen’s weight, cabling, or ventilation needs.
The fix: bring screen requirements into the stand design brief early. This causes the structure is built around the screen rather than the screen being forced to fit an existing structure. Your stand designer and project manager should be able to source and cost this for you.
3. Underestimating Power and Rigging Within the Venue
Exhibition venues have their own rules on rigging points, floor loading, and available power per stand. These vary by venue, and even by hall. LED screens draw more power than most exhibitors expect. A screen that needs rigging from the venue ceiling has to be booked and approved through the organiser’s technical process. This has its own deadlines separate from the stand build.
The fix: confirm power allocation and rigging permissions with the venue and organiser as part of early stand planning. Don’t wait until the screen has already been booked. Or allow your end-to-end partners do this as part of their project management role.
4. Ignoring Viewing Angle on Wide or Curved Stands
Every LED panel has a maximum angle before brightness and colour start to drop off. Most exhibition stands are an open design by necessity to draw traffic from multiple aisles. Visitors approaching from an angle rather than head-on are common, and a screen with a narrow viewing angle can look washed out from exactly the direction most people will actually see it.
The fix: position screens with the realistic approach angles of the stand in mind, not just a straight-on sightline.
5. Booking Indoor-Rated Panels for Bright, Glass-Roofed Halls
Not every exhibition hall is a dark, controlled indoor environment, many venues have large glass roofs or bright ambient hall lighting that behaves more like daylight than typical indoor lighting. A standard indoor-rated panel can wash out under this kind of ambient light, particularly on stands positioned near windows or atriums.
The fix: check the actual lighting conditions of the specific hall and stand location, not just whether the show is technically “indoors.” Your stand design and build partner should have a good knowledge of your venue or have researched it in advance to be able to advise you.
6. Building Generic Content That Doesn’t Fit the Screen
LED walls have a fixed resolution based on their physical size and pixel pitch. That resolution is rarely a standard slide or video ratio. Content built generically for a laptop or projector often needs reformatting, and on a stand build this tends to surface during on-site setup, the worst possible time to discover it, with build-up hours already tight.
The fix: get exact resolution and aspect ratio from the screen supplier or your designer as soon as size and position are confirmed, and hand that spec directly to whoever is producing the content.
7. Booking the Screen Too Late in the Stand Build Process
LED screens are specialist equipment, and availability of specific sizes and pixel pitches narrows fast during peak exhibition season, when many stands across different shows are competing for the same supplier stock. Leaving the screen as a late addition to a finished stand design often means compromising on spec, not genuine choice.
The fix: confirm LED requirements at the same stage as the rest of the stand design and build schedule, not after the structure is already locked in.
Quick Reference: What to Confirm Before Booking
- Exact viewing distance from the screen’s actual position on the stand
- Whether the fascia, wall, or media unit is structurally built for the screen’s weight and cabling
- Power allocation and any rigging approvals required by the venue and organiser
- Realistic approach angles visitors will view the screen from
- Ambient light conditions of the specific hall and stand location
- Exact resolution and aspect ratio, shared with content producers early
- Booking timeline relative to peak exhibition season
Frequently Asked Questions
What pixel pitch is best for an exhibition stand screen? It depends on where the screen sits. For screens at eye level near the aisle, where visitors stand close, a finer pixel pitch (broadly P1.5–P2.9) keeps text and branding sharp. For screens mounted higher on a fascia and viewed from further back, a wider pitch delivers the same visual quality for less cost.
Should LED screens be planned with the stand design or booked separately? Ideally planned together. Booking a screen separately from the stand structure is one of the most common causes of last-minute issues. Mismatched sizing, unplanned power draw, or a fascia that wasn’t built to carry the screen’s weight.
How early should LED screens be confirmed for an exhibition stand? At the same stage as the rest of the stand design, not as a late add-on. Specific panel sizes and pixel pitches become harder to source the closer you get to peak exhibition season.
Tecna integrates LED and event technology into exhibition stand design from the earliest planning stage, so screen spec, structure, power, and content are resolved before build, not during it. Get in touch to talk through your next stand.
