Hi.

I have a new Raspberry Pi4B updated to last firmware (rpi-update).

The FullPage OS is fullpageos-buster-lite-0.11.0.

To this Pi4 is two new HDMI Philips monitors connected.

The /boot/config.txt file is unchanged.

The problem is that at the screen shows in Extended mode all time. I want to show same screen on both monitors in duplicate mode.

When the computer boot up, the boot text will be in duplicate mode.

OBS. If i run Raspberry´s original raspbian-buster-full desktopversion the screen work´s perfect in duplicate mode.

Is there maybe anyone who can help me to setup an working /boot/config.txt file?

Thank´s for all help! ;-)

Best regard´s,
McLund
