Connection HDMI to PC-Monitor

[hansp]

Hello friends,
I connected the raspberry with a hdmi-cable to an full HD monitor. How I can switch the output to the HDMI format? I found only the settings for PAL or NTCS in the VOMP menue. It would be very nice if someone can help me.
best regards
peter

Hello, the problem is solved. I have changed to libreELEC and all works fine.
