Screen Size Calculator (LED)
Calculates recommended LED display dimensions and pixel resolution from viewing distance.
How to use: Enter a location name, the maximum viewing distance (last row distance), and the LED pixel pitch.
Display height and width (in metres) are computed for three viewing area types — Analytical (÷4),
Basic (÷6), and Passive (÷8) — along with the corresponding pixel resolution for each.
Aspect ratio 16:9 (×1.777) is assumed. All formulas use ROUNDUP.

Projection Screen & Pixel Size Calculator
Calculates ideal projection screen dimensions and projected pixel size from viewing distance.
How to use: Enter the location name, max viewing distance, and projected resolution (H × V pixels).
Screen height is derived from distance ÷ divisor; width = height × 1.777 (16:9 ratio).
Pixel size (mm) = screen width (m) × 1000 ÷ horizontal resolution.
All dimension formulas use ROUNDUP.

NDI Bandwidth Calculator
Calculates total NDI bandwidth and network utilisation for multiple stream groups.
How to use: Add one or more stream groups. Select the NDI format — resolution, frame rate, and max bandwidth per stream
are looked up automatically. Data Rate (Gb/s) = streams × bandwidth ÷ 1000.
Network utilisation is shown for 1G and 10G links.

Renderstream Bandwidth Calculator
Calculates raw uncompressed Renderstream bandwidth for 25G and 100G networks.
Formula: Data Rate (Gb/s) = ROUND(W × overscan × H × overscan × FPS × bitsPerPixel ÷ 1,000,000,000 , 3) × streams
Bits per pixel: YUV 4:2:2 = 2 × bit depth | YUV 4:4:4 = 3 × bit depth | RGBA = 4 × bit depth

disguise Load Calculator
Calculates pixel load per screen and recommends disguise server configurations.
Pixel resolution = ROUND(dimension_m × 1000 ÷ pixel_pitch_mm, 0).
Fraction of 4K = ROUND(pixels_per_frame ÷ (3840×2160), 3).
Fraction of HD = ROUND(pixels_per_frame ÷ (1920×1080), 3).
Server recommendations use ROUNDUP on total HD fractions.
