Use the rear path, not the diagonal alone

TV Bias-Lighting Size Guide

Estimate three- or four-side strip length from TV width and height, wall distance, and sync preference.

Planning result

8.5 ft measured-path estimate · plan around 8.9 ft before cut constraints

Three sides using a 16:9 estimate from diagonal size. Measure the actual rear mounting path before ordering.

Estimated dimensions: 47.9 in × 27 in
Wall distance: 3 in; check halo spread and hot spots
Control approach: Static light
Installation: Keep vents, ports, labels, stand hardware, and service panels clear

Verify before acting

Verify cut intervals, controller limits, and the exact rear route.
Do not assume the TV USB port supplies enough power or switches as desired.
