I just bought a new iMac, and I have the following situation.
In the Energy Saver preference, I have "Turn display off after:" set to 3 minutes. But the display never turns off. Every time I walk past the room with my computer in it, the screen is blazing away, regardless of how long it's been since I've touched it.
What's making it stay on?

The keyboard shortcut Control–Shift–Media Eject will put your displays to sleep immediately. Mac keyboard shortcuts - Apple Support
A ‘hot corner’ can be set to sleep the monitor as one of the possible actions (instead of a regular screen saver), in the screen saver options. Use hot corners to start the screen saver on Mac - Apple Support
Use the Energy Saver settings on your Mac - Apple Support
If your Mac doesn't sleep or wake when expected - Apple Support
If your mouse pointer is a bit unstable because of micro trembling or because of the surface it is sitting on, then that may be perceived as activity to prevent the display from sleeping.
Some apps may do things that prevent sleep. Can you see different behavior depending on which apps are running?
