Problem with two monitors and fullscreen

After solving the problem with the laptop-lid occured a new problem with the resolution of fullscreen. On my sytem are 2 monitors, the laptop-screen with 1366 x 768 and the tv-screen with 1920 x 1080 resolution. The laptop is closed and the tv is the main-screen. When I switch the windows in xfce to fullscreen the resolution switches only to 1366 x 768. I can manualy enlarge the windows to the full size, but by enabling fullscreen it switches back to 1366 x 768. Watching video in fullscreen is not possible (vlc, telegram, firefox).

This is the actuell output of xini:

I donĀ“t know where to change it, in Display-manager or XFCE-settings?

Thank you

I could find a workaround, after dissabling the laptopscreen in displaysettings fullscreen is working.
