Your file plays from this browser and is never uploaded. The player centres every wall shape on the room’s back wall. The design canvas is 3846 × 2166 px; the preview also draws each screen’s outer frame to physical scale.

What to design at

Design canvas: 3846 × 2166px
Screens only: 3840 × 2160px
Gap between screens: 6 × 6px

The simulator plays your file across the design canvas and gives every screen its own slice, gaps and all — the same maths the players run on site.

Standing back from it

Closest anyone should stand: 0.60 m
Takes the whole wall in: 3.40 m
Fine text stops reading: 11.00 m

The person in the room stands a few metres back, which is what tells you whether this wall is the right size for the place it is going.

What the room is, and is notThe picture never changes a number

The room is a drawing. The wall in it is exactly 2.44 m × 1.38 m, the size your screens really make, and the person is 1.72 m tall.
The picture on the glass is the real thing: every screen is drawn by replaying what its player does with the instructions it would be sent.
Plain view turns the room off and leaves the wall on its own. Every number on this page is the same either way.

Where the answers come from

This is castv.ai's own wall simulator: each screen replays what its player does with the instructions it receives, at its real resolution, then scaled onto the panel. The picture here is the picture on the glass.
