Display selection

Hardware requirements lists the spec. This page is the why — the trade-offs behind each choice and the pitfalls that show up only after you've already deployed.

The thinking that helps most: a sign isn't a TV. A TV is something you turn on for a few hours of focused viewing in a controlled-light room. A sign is something that runs 16+ hours a day in unpredictable lighting, viewed in passing, and replaced when it dies. Treat them differently.

Industry guidance, not DisplaySync-validated specifics

This page distills common digital-signage and AV-industry practice. Specific numbers (nit ranges, dwell times, viewing-distance multipliers) reflect widely-cited rules of thumb rather than DisplaySync-tested figures. Use them as starting points and verify against your venues and your team's experience.

Brightness is the most-mistaken spec

Most teams pick a display by size and resolution, then realize at the venue that no one can see what's on it.

Reference points:

  • Office monitor / consumer TV: ~250 nits. Fine for indoors, dim rooms.
  • Lobby / hallway: 350 nits is the floor. 400-500 is comfortable.
  • Near windows or open atria: 700+ nits. The sun is brighter than you remember.
  • Outdoor: 1500-2500 nits. Outside DisplaySync's typical scope.

A sign that washes out at the venue isn't broken; it just wasn't bright enough for that room. The problem is the wrong panel — there's no software workaround. Spec for the worst-case lighting in the room, not the average.

If you're inheriting a venue's existing displays, photograph them lit up at the time of day your event runs. If they look weak in your photo, they'll look worse to attendees.

Commercial vs consumer panels

This is the second-most-mistaken spec.

Consumer TVs are warranted for ~8 hours/day of use. They will physically run for longer, but the warranty doesn't, and over months you'll see image-retention, backlight failure, and inputs forgetting their HDMI mode after power cycles.

Commercial signage panels are warranted for 16/7 or 24/7. Almost identical hardware in many cases — the difference is the manufacturer's confidence in the product running unattended for years. That confidence reflects QA you can't see directly but that pays off in your fleet's failure rate.

Look for "signage" or "display" in the product line name when shortlisting — the major commercial-display vendors all maintain dedicated signage lines distinct from their consumer TV ranges. "TV" or "Smart TV" in the product name is a flag worth questioning.

Resolution

1080p (1920×1080) is the workhorse. Upgrade to 4K only when:

  • The display is large enough that 4K resolution is visible (think 65" and up at near viewing distances)
  • Your content is authored at 4K. Upscaling 1080p to 4K doesn't make it sharper; it makes it slightly blurrier.
  • Your kiosk hardware can drive 4K at 60 Hz comfortably (Intel N100 struggles; N200 / i3 is the floor)

For most signage — wayfinding, sponsor logos, schedule displays — 1080p is correct and 4K is a budget hit with no visible benefit.

Refresh rate

60 Hz is the right answer. Higher is wasted on signage content (which is mostly static or slow-changing). Some commercial panels offer 120 Hz; that's a gaming-monitor feature priced into a signage panel that doesn't need it.

Panel type

TypeBest forTrade-off
IPSWide viewing angles — sponsor walls, hallwaysSlightly weaker contrast in dim rooms
VAHigher contrast in dim rooms — keynote screens, dim ballroomsNarrower viewing angle (off-axis loses contrast)
OLEDBest contrast, deepest blacksImage retention risk for static signage; expensive; usually overkill

IPS by default. Reach for VA only when you know the room is dim and viewers are mostly straight-on.

Orientation: landscape vs portrait

Landscape is the default and the right answer 80% of the time. Portrait works fine for:

  • Wayfinding signs in hallways (matches the human eye's vertical scan)
  • Schedule displays with long lists of agenda items
  • Standees alongside printed posters

Things to know about portrait:

  • The kiosk OS handles rotation cleanly via display settings. Set it once during the image build so it persists.
  • Your content has to know it's portrait. A landscape webpage rotated 90° looks like a webpage rotated 90°. Build a separate portrait layout via media queries (@media (orientation: portrait)).
  • Some panels rotate better than others. Cheap consumer panels often have terrible viewing angles in portrait because their IPS is tuned for horizontal viewing. Test before deploying.
  • VESA mounts in portrait need to be rated for it. Many cheap arms don't have the leverage tolerance.

Fleet-level orientation strategy

Mixing orientations within a single event is doable but adds operator cognitive load:

  • Single orientation per fleet when possible. Pick by venue type:
    • Portrait wins for narrow lobbies, info kiosks, vertical wayfinding
    • Landscape wins for wider walls, multi-pane sponsor screens, status displays
  • If mixing is required, separate naming conventions help — -L-01 vs -P-01 suffixes, or distinct venue-area prefixes.
  • Standardize hardware per orientation. Different mounts, different cable routing, different spares in the kit.

Bezels and video walls

For single-panel signage, bezel doesn't matter much. Pick what looks reasonable.

For video walls — multiple panels showing one continuous image — bezel becomes the central design constraint:

  • Standard panels: 7-15 mm combined bezel. Acceptable for content with strong divisions; visible interruption for continuous imagery.
  • "Ultra-narrow bezel" / "video wall" panels: 1.5-3.5 mm combined. The right answer for video walls.
  • LED panels (no bezels at all): the premium option for very large or curved walls. Different vendor ecosystem; usually outside DisplaySync's wheelhouse but works fine when driven via HDMI.

Test with content. A 7 mm bezel between two panels is invisible during the seam-aligned splash, glaring during a continuous-pan video. Pick the bezel that matches how your content uses the wall.

Connectors

HDMI 2.0+ for 1080p60 or 4K. DisplayPort works equally well if your kiosk has it.

Adapters:

  • DisplayPort → HDMI active adapters are reliable. Passive adapters sometimes work, sometimes don't — keep one of each in your tool kit.
  • USB-C → HDMI if your kiosk has Thunderbolt / USB-C output. Check the cable rating.
  • Avoid HDMI extenders over Cat6 unless you've tested the specific brand at your specific length. Many work; many don't; figuring out which has bitten teams more than once.

Rule of thumb: shorter cables fail less often. Don't run a 50' HDMI when you can VESA-mount the kiosk to the back of the display and use a 6" cable.

Cable management at the venue

HDMI run-length thresholds matter more on event floors than in office installs:

Run lengthCable type
≤ 15 ftPassive copper HDMI — no concerns
15-50 ftActive HDMI (amplified) or fiber HDMI; passive copper at this length is the most common video-fail mode
> 50 ftFiber HDMI or HDMI distribution amplifier

On the floor:

  • Tape cable runs to the wall where possible. Use cord-cover (PathWalker, Yellow Jacket) on traffic paths.
  • Power and data on separate runs to reduce interference.
  • Spare cables of every length in your kit. HDMI failures during load-in are common; a 25-ft active HDMI that nobody packed is the kind of problem that costs an hour.

What to avoid

  • Touchscreens unless your content is genuinely interactive. Bare touchscreens in public spaces invite trouble — kids, drunk attendees, unintended interactions. Disable touch in the OS unless you need it.
  • "Smart TVs" as monitors. They boot slowly, sometimes show their own splash screens before HDMI input renders, occasionally reset HDMI input after power cycles, and run apps you can't disable.
  • 3D / curved consumer panels. Pointless for signage, expensive when one dies.
  • No-name AliExpress panels for production deployments. Fine for testing; risky for shows where a failure costs more than the savings.

Power

A typical sign — commercial display + thin client + small UPS — draws on the order of 100-200 W, depending on display size and brightness. Check the actual rating of the panels and clients you're using before sizing venue power runs; LED panels and 4K displays can be considerably higher.

A small UPS buys you enough runtime through brief blackouts to keep the wall up — see Live event checklist → Hardware.

Mounting

  • VESA-mount the kiosk to the back of the display. Every cable run is a failure mode.
  • Cable management matters. Slack cables behind a sign are a maintenance nightmare and a tripping hazard.
  • Active cooling for hot rooms. Packed ballrooms hit 30 °C+. Fanless mini PCs throttle there. Spec accordingly.
  • Anti-theft mounts for displays in lobbies or unsupervised venues.
