Agreed, in computers all of the input power becomes waste heat.
One small exception may be microntollers that use PWM to emit a signal through an antenna, or to drive a motor. I think in that case some of the energy becomes radio waves (which may never be absorbed entirely so they may not become heat) or motion in the motor.

- tsimionescu 2y agoMonitors have an external power source, I have never heard of a monitor being powered by signal coming from the CPU or GPU. That is, the control signal coming from the CPU/GPU doesn't become light, it merely helps decide what light a separate circuit might emit.
