Thank you for the answers.
With an HDMI splitter yes
If the connections are there you can do that. But you can't have two input sources displayed on the same screen at the same time.
HDMI 1 connection is still free. Do you know how I switch from HDMI 2 to HDMI 1?
There are buttons down there
Via the buttons on the monitor. Just press one and the rest will be shown.
Either the monitor has buttons on the side to switch (source ") or the Samsung often has the on / off button behind the screen as a joystick
