Question

How are screens with higher resolutions able to reduce energy consumption when adjusting to lower pixel counts, when the same amount of diodes are still present?

In: Technology

Answer 1

The screen itself will most likely keep using the same amount of energy assuming you don’t change the brightness or anything, but the computer controlling it will use less energy because it has less processing work to do.

Lower resution means fewer pixels, and that means the graphics processor won’t have to do as many calculations to drive them. This lets it slow down its processing speed, produce less heat, and consume less power.
