So i mean the other rum i want second screen from my tv on laptop. Do you know how that works?
Not at all by cable.
Apart from why you should do something like that…
It's not working". No manufacturer builds something like this. So if you need equipment that intercepts the signals and then forwards to your laptop. So if you have a few € then have fun. Get a company and let it do you. Alone, you certainly can't do that.
Assuming I understood you correctly.
I hope I understand you correctly, you want the picture of the TV is displayed on your laptop monitor. It depends on what you want to reproduce exactly.
You can usually do this by buying a capture card and then connecting the receiver, console, DVD / BD player, etc. To it. Some capture cards pass through the input signal, so then behind the capture card can then connect the TV. If the signal is not transmitted, you will need an HDMI distributor (1 in, 2 out). The capture card itself then usually transmits the signal via USB to the PC / laptop and can be connected to e.g. The supplied software will then be reproduced.
However, some receivers and DVD / BD players use https://de.wikipedia.org/...Protection, which is to prevent the picking up of video and audio signals and therefore is not played by many capture cards via the PC / laptop.
