Connect two televisions?
Since I now have two televisions in the room, I would like to know whether it is possible that the same picture is played on both, e.g. Netflix or YouTube. Is there any way to do this?
The two devices can't communicate with each other. However, you can of course use both devices from one source, e.g. Power your laptop via HDMI (or other available connections).
If you go to the two televisions with a Y cable from your sat cable you can watch television.
Netflix would be exciting, I've never tried it.
Resparie pi + two hdmi sockets / laptop + two hdmi sockets and connect to both televisions
If I have connected an Xbox with HDMI to one of the two TVs, is it also not possible?
Just over a splinter
Sorry, but SAT systems and Y-cables do not work at all, each SAT receiver needs its own SAT line to the SAT distributor or to the LNB of the SAT dish, which the receiver sends control signals to the distributor or LNB and receives the desired SAT IF band. In other words, several SAT receivers / tuners must not be operated on the same SAT line at the same time.

Sorry, I have to contradict again, you can google, …
But, these are mostly BK + SAT splitters with 3 connections (= separation of SAT + TV), which we never work with SAT signals. And those with 8 or more connections are actually SAT distributors (SAT switches), but I don't think the FS wants to lay 5 or more antenna cables in / between the rooms.
Y-distributor not only means that the connections fit, the right technology must also be built into the supposed Y-distributor. And a SAT switch (that would be the right thing, that it could work at all) always has at least 4 inputs (VL, HL, VH, HH) and at least 2 (often more than 8 or 16) outputs for the SAT receiver.
Here it is explained clearly, look at the picture:
