You booked the wall. The supplier installed it. Then the content went up and something looked off - soft edges, stretched logos, text you cannot read from three metres back.
Almost always, the cause is the same: the content was made for a normal video frame and then forced onto a screen that is not a normal video frame.
LED walls are not 16:9
A stand wall is built from panels. Its resolution is whatever those panels add up to - 1408x768, 2560x960, 3840x1080, or something stranger if the wall curves or wraps a corner. None of those are 16:9.
When you hand over a 1920x1080 file, something has to give. The processor scales it, crops it, or pillarboxes it. Every one of those options degrades the image, and the one it picks is rarely the one you would have picked.
Ask for three numbers before anyone designs anything
Before a single frame is designed, get these from your screen supplier:
- Native resolution in pixels - the actual panel count, not the physical size
- Pixel pitch - the distance between LEDs, which sets the minimum readable text size
- Processor and accepted formats - what codec, container and frame rate it will play
With those three, content can be built at the exact canvas from the first day. Without them, you are guessing and correcting later.
Pixel pitch decides your typography
Pixel pitch is the number that catches people out. A 2.6mm pitch wall resolves fine detail at close range. A 6mm pitch wall in the same physical size has far fewer pixels, so thin type and fine line work simply disintegrate.
The practical rule: the larger the pitch, the heavier your type weight and the simpler your graphics need to be. This is a design constraint, not a technical footnote, and it needs to be known before layouts are approved.
Viewing distance changes everything
People do not stand still in front of an exhibition wall. They pass it at four metres while walking, then stop at one metre when something catches them.
Content has to work at both distances. That usually means a bold, legible layer that reads in motion, and a detail layer that rewards someone who stops. Trying to serve both with one uniform design tends to serve neither.
Deliver what the processor wants
The last mile is where show-day problems happen. A file that plays perfectly on a laptop can stutter or refuse to load on a media player. Confirm the codec, bitrate ceiling and frame rate with whoever runs the playback, and test on the actual hardware if you can get access during build.
If you want this handled end to end - built at native resolution and delivered in the format your processor actually accepts - that is what our LED wall content production work covers.
