Planar TVF Series P1.5 — cabinet grid & viewing distance

Pixel pitch is the single number that drives everything else in this preset. At 1.56 mm, the calculator resolves the 4 x 2.25 m target into a 7 x 7 cabinet grid, and the same 1.56 mm figure sets the optimal viewing band for video content at roughly 1.6-3.1 m (pitch x 1.0 to pitch x 2.0). Seat viewers any closer than about 1.6 m and individual pixels start to separate visually; push them past 3.1 m and the wall is under-resolved for its size.

800 nits is a controlled-indoor brightness figure — comfortable for a lobby, boardroom, control room or similar space without direct sun or bright competing light sources, not a daylight or semi-outdoor rating. The cabinet is wall-mount with front-service access, which matters when the installation has no rear void to walk into for maintenance. Native resolution at this preset's wall size is 2688 x 1512 (about 4.1 MP), which suits video, digital signage and control-room content comfortably; it is close to but not exactly a broadcast 4K standard, which matters if content is mastered at a fixed resolution.

To use the calculator, drag the wall width and height sliders and watch the cabinet grid and native resolution recompute in real time. Cabinets are whole units, so the calculator rounds UP to the next full cabinet count — never down — and the finished wall is never smaller than the target. In this preset a 4 x 2.25 m target finishes at 4.2 x 2.36 m, about 5 % over on each axis: expected behaviour rather than an error, and the figure the opening is built to.

The calculator does not decide structural or rigging load capacity, power and data cable run lengths, the video processor or scaler needed to feed the wall, how source content resolution maps onto the native 2688 x 1512 panel, or ambient-light calibration for the room the wall sits in. Each of those is a separate engineering decision that follows once the cabinet grid and viewing geometry are set.
