Problem with full screen

I set Zwift to full-screen mode.
After restarting it really started in full-screen but the monitor gives me a message thet the FTP range is not supported.
Zwift running in the background but I have no chance to change it back to window-mode.
I have an LG led-monitor. The grahpic card (Nvidia Quadro K2200) driver was just updated.

Could somebody help me how to solve the problem?
Thank you in advance!

Hi @Zoltan_Nadler

Welcome to the forum.

Open your prefs.xml file “\Documents\Zwift” and change this line.
0 = Windowed mode.


Thank you @Gerrie_Delport_ODZ !
