I've had problems with modern monitors shutting themselves off if they don't detect a signal in something like five or ten seconds, which is far too short when I'm trying to debug a PC having boot issues, configure a multi-monitor setup (like a 3-screen virtual pinball cabinet) or even just figure out which HDMI cable is which on the PC end. I don't mind the auto-off feature but the incredibly short time period is unnecessary and the delay time isn't adjustable (at least on the LG monitors I have). This over-aggressiveness turns a good feature into a problem forcing me to completely disable power saving. Which is sad because the biggest savings of the feature are when a screen is left on for hours when the PC is off or disconnected (which I don't do anyway, as the entire system is on a smart power strip). A monitor should hunt for a valid signal for at least 45 or 60 seconds by default before auto-offing itself. Another "power saving gone awry" issue is that USB selective suspend can cause wireless mice to stutter after not moving for just a few seconds. I think this is due to lag in the wake-up time. Unfortunately, the interface doesn't have any time adjustment, so I have to just turn selective suspend.
