LED Video Wall Specs Decoded: Nits, Refresh Rate, and What Actually Matters

LED spec sheets are full of numbers designed to sound impressive. Only a few actually change how your wall performs in a trade show hall. Here's what to read and what to ignore.

Brightness (nits)

Nits measure brightness. Trade show halls are brightly lit, so a wall needs enough nits to look vivid rather than washed out — indoor walls are typically far brighter than a living-room TV. Ask for the sustained, full-field brightness, not a peak number a wall can only hit on a small patch. If your booth sits under bright hall lighting or near a window, brightness matters more.

Refresh rate (and why it matters on camera)

Refresh rate is how many times per second the wall redraws. To your eye, most walls look fine. To a camera, a low refresh rate produces scan lines and flicker. If your wall will be photographed or livestreamed — most Vegas booths are — you want a high refresh rate (commonly 1920Hz or 3840Hz on event-grade walls) so footage looks clean.

The specs that matter less than vendors imply

“Contrast ratio” and headline color-depth numbers sound important but vary in how they're measured; judge real image quality by seeing content on the actual wall, not by a number. Pixel pitch and brightness do more for how your wall reads on the floor than most of the spec sheet.

Tell us your booth's lighting and whether you're filming, and we'll spec brightness and refresh that hold up — part of your free quote.

Frequently asked

How many nits do I need?

Enough to stay vivid under bright hall lighting — indoor event walls run far brighter than a home TV. We size brightness to your booth's lighting; tell us if you're near a window or under spotlights.

Why does my wall look bad on camera but fine in person?

Usually a low refresh rate (and sometimes a coarse pixel pitch) showing scan lines to the camera. If you're filming or livestreaming, ask for a high-refresh, event-grade wall.
