What is USB-C cable?
It is the number of pixels in an image, affecting sharpness. 4k is an example.
What is resolution?
This term refers to the process of converting raw video footage into a compressed digital format for storage, transmission, or playback.
What is encoding? (compression accepted)
This is the physical distance between the projector and the projection surface (screen).
What is projection distance?
These are bright, modular panels used in concerts, TV studios, and digital signage.
What are LED Screens or LED Walls?
This is the standard digital interface for video and audio but cable length can be limited without boosters.
What is HDMI?
