1. A display system, comprising:
a spatial light modulator (SLM) comprising pixel elements; and
a circuit comprising a control processor, the circuit communicatively coupled to the SLM, the circuit configured to:
convert M primary video signals to N multi-primary video signals, wherein N and M are positive integers and N is greater than M;
use a first multi-primary video signal of the N multi-primary video signals to derive a first additive offset for a first primary video signal of the M primary video signals;
use the first multi-primary video signal to derive a second additive offset for a second primary video signal of the M primary video signals;
add the first additive offset to the first primary video signal; and
add the second additive offset to the second primary video signal;
derive a bit plane based on the first primary video signal having the first additive offset added thereto; and
transmit the bit plane to the SLM to selectively control on and off states of the pixel elements of the SLM.
