I bought such HDMI cables a few years ago. There was no 4k TV at that time. Can you really tell the difference between my older HDMI cable and one that is sold as 4k?

I will get the new UHD TV box from Swisscom. In your opinion, does it make more sense to connect the UHD TV box with such a 4k HDMI cable or is an older HDMI cable still sufficient?

Answer

If you want to use the UHD box from Swisscom, you must use a 4K cable. Otherwise HDCP 2.2 is not available and you cannot watch 4K programmes on your TV. Of course, you also need the corresponding TV and possibly an AVR that can process these signals.

Your data. Your choice.
