Stream Deck with Soundflow screen saver ... is it safe?

Hello all, I just got a Stream Deck and I'm using it with Soundflow. I noticed that when the computer goes to the screen saver, the Stream Deck also displays a Soundflow screensaver that rotates through the different colors.

However eventually my computer's monitor goes to sleep, and I leave the computer on all the time to do maintenance tasks overnight, etc. I noticed in the morning that the Stream Deck still has the Soundflow logo displaying: it never goes to sleep.

Is this safe? Is there a way to get the Stream Deck to go to sleep after a certain amount of time? Or does it not matter? Just want to make sure I don't get any burn-in, or any other negative effects.

Thanks!
