Displays & Projection
View all →Screen size, viewing distance, projectors and LED walls.
Display Planner
PlannerPlan a whole display setup: viewing distance by use case (presentation, cinema, signage, gaming) and technology (TV, projector, LED wall, monitor) — with a room plan.
Projection Planner
PlannerPlan a projector: screen size, throw distance and lens, and the lumens needed — with side and top views.
LED Wall Planner
PlannerMatch LED cabinets to a screen size — actual dimensions, resolution, power draw (W/A) and the cabling plan.
DOOH Planner
PlannerPlan an outdoor digital screen: size it, draw the road, and get readability zones, dwell time and retina distance for drivers and pedestrians.
Screen Size Calculator
Convert between a screen diagonal, width, and height for any aspect ratio.
Projector Throw Distance Calculator
Find the projector installation distance from screen width and throw ratio — or work backwards from a distance.
Projector Brightness Calculator
Find the projector lumens needed for a target brightness in nits, lux or footcandles — with the equivalent in all three units.
LED Pixel Pitch Calculator
Calculate an LED wall's pixel count, viewing distance and content resolution from its size and pixel pitch.
Video & Streaming
