It doesn't matter in terms of image quality. You should have the full resolution with both. HDMI can also transmit sound. Displayport cannot. Displayport has sync functions, which are important for gamers. Personally, I would use HDMI for video editing. The most that can happen is that your two devices do not work well together with one or the other connection method. You'll have to try that out for yourself.
Hello Buciboy
If I have understood you correctly, you want to connect an AV receiver between the TV and the Swisscom TV box.
Scheme as follows: [Swisscom TV Box] -------------[AV receiver]--------------[TV]
If you connect the products in exactly the same way, you don't have to take ARC into account because the signal originally comes from the TV box and the receiver can only pass on the video signal.
In plain language, this means: Sound via the receiver and picture via the TV.
And finally, to answer your question.
Yes, if you connect your products at home exactly as described above, the cable will work.
Greetings John
The HDMI cable is HDMI 2.0 so it should support arc, your TV connection should also support arc.
According to Google, this is the case from version 1.4.
I would therefore say that it is possible to connect the Teufel Box to the TV with this cable, provided that the HDMI connection of the TV is 1.4 or higher.
