Hi Thomas, I'm not an expert but I've had my XDJ's for 12 months and I've never seen a screen saver. You can set the screen brightness and also set this to dim when inactive for a period of time but not sure the player enters any kind of power saving mode.
I'd imagine they're designed to be switched on and off when not in use. They boot up fairly quickly and the only reason I'd see to leaving them on is to keep the pro-DJ link active (as sometimes the link between them and my DJM-900NXS2 doesn't startup as expected on boot - requiring a restart). If you don't have this issue then I'd just switch them on and off as needed.
Off topic and as a fellow XDJ'er... What mixer are you using and do you have any pro-DJ probs at all?
