Ask HN: Can you recommend an “instant-switch” Monitor? Does one exist?

Current situation: - I have three sources connected to my monitor (1 HDMI, 1 DP, 1 USB C). - The monitor is on a switched off source i.e. due power save mode. - When I try to switch to another source, it takes 4 seconds or more to switch

What the monitor should do: S - Switch instantly no matter if the current source is on or not.

WHY the long delay??? It is really something that angers me.every.damn.time.

I have a Dell U2723QE, but older models have that as well as others from other brands.

Would love to get a recommendation for an instant switch model.
