I am currently using Fedora 27 with GNOME3 and I have a problem. I use my system with three displays, and unfortunately, when I press Win+L to lock my current session, my displays on the sides go to power saving mode properly, but my main display does not, therefore the mouse pointer still appears on the screen as this self-made video suggests. video on Vimeo

Is there any way to solve this problem?

Hmm, I though Super-L only locked the screen. A Google search turns up people complaining about the opposite problem, in that the display turns off on lock rather than displaying a lock screen.

Thanks for your answer. Since I posted my question, I was continuously searching for a solution. As some pointed out (in an FB group) I had forgotten to share some crucial information, namely the type of connection between displays. The two on the sides are connected via DVI, and my main display (where I experienced the error described) is connected via DP, and since DPMS is not implemented in the proprietary nVidia driver (what can cause the same syptoms), as a suggestion I got the following to try: change the cable to HDMI where DPMS is also supported just as in the case of DVI.
