A video wall used to mean specialist panels, a hardware controller, and an installer who knew its menus. With DisplayNyx screen groups, any screens running the DisplayNyx player can become one big display: a 2x2 behind a reception desk, a 3x1 menu wall over a counter, or a 4x4 in a showroom. This guide walks through planning the wall, setting it up, and getting the seams to look right.
1. Plan the grid
Decide how many screens wide and tall the wall will be. A screen group can hold anywhere from 2 to 64 screens in any rows by columns grid, and each screen can be landscape or portrait. Use identical screens where you can: the same model gives the same picture size, colour, and brightness, which matters more on a wall than anywhere else because every screen sits right next to its neighbour.
- Narrow-bezel commercial panels (around 1 to 4 mm per side) give the most seamless result.
- Regular TVs work too. Their frames are thicker, which is exactly what bezel compensation is for.
- Mount the screens as close together as you can. Every millimetre of gap is a millimetre of hidden picture.
2. Create the screen group
In the dashboard, open Screen Groups and create a group with your rows, columns, and orientation. DisplayNyx creates one screen for every position in the grid and places each one in its cell automatically, so there's nothing to drag around. One screen is marked as the primary, which is simply a label for whichever screen your installer treats as the reference.
Then, on the Grid tab, set each screen's orientation to how it sits in the wall and its rotation to how the unit is mounted. A TV hung on its side as a portrait screen usually needs 90° or 270°. Leave rotation on Location default for screens that should follow the location's own setting. When a wall mixes orientations, DisplayNyx treats it like a mounting grid: each column is as wide as its widest screen, each row as tall as its tallest, and every screen sits centred in its slot.
3. Measure for bezel compensation
Every screen has a frame around its picture, so a wall has dark strips between the screens. If each screen just shows an even share of the picture, anything crossing a strip (a diagonal line, a circle, a logo) looks broken at every seam. Bezel compensation fixes that by treating the strips as part of the picture: the slice that would sit behind a frame is hidden, like looking at a scene through a window frame, and lines carry on straight on the other side.
On the group's Bezels tab, enter the screen size. The diagonal in inches is enough for a standard 16:9 screen, and DisplayNyx fills in the picture width and height for you. Then measure each screen's frame: the distance from the edge of the lit picture to the outer edge of the screen, on the top, right, bottom, and left. Enter them for one screen and copy them to the rest, or set each screen separately if a wall mixes panel batches.
- Measure with the screen switched on, from the last lit pixel to the outer edge of the frame.
- Include any physical gap between two mounted screens in the frame width of one of them.
- Use the live test pattern on the Bezels tab. With the right values, its diagonals and circle run straight across every seam.
4. Add the wall's content
On the Media tab, build the wall's rotation: images and videos, each with its own duration, transition, playback speed, and sound settings. Wide content looks best, so design for the whole wall's shape rather than a single screen. Keep important text away from the seams, because with compensation on a few pixels of it will sit behind a frame.
5. Pair the screens
Add a location on the Locations tab and every screen in the group gets its own pairing code there. Enter each code on the matching physical display and the wall starts playing. Deploying the same wall to another store is just another location: each screen gets a fresh code for that site.
How the screens stay in sync
Each screen works out what to show from the current time and the wall's rotation, so every screen lands on the same item at the same moment without needing to talk to the others. If one reboots or loses its connection for a while, it rejoins at the right point instead of restarting the rotation. Announcements and live voice broadcasts still take over the wall like any other screen, and the rotation carries on afterwards.
Quick checklist
- Identical screens, mounted as tightly as possible.
- Screen group created with the right rows and columns.
- Each screen's orientation and rotation set to match how it is mounted.
- Screen size and every frame width entered on the Bezels tab, checked against the test pattern.
- Content designed for the whole wall's shape, with text kept clear of the seams.
- Every screen paired at its location.
