What are you even getting at here? That is a totally different use case. A display is supposed to always be on, while a cpu should turn off while not in use. When a cpu has no work it slows down to conserve power and reduce heat output. What happens when a monitor has no input data? It goes to sleep. It doesn't just display the last thing and continue processing a stream of data from it's input.
