There are no AV receivers or TVs that have a Gbit Ethernet port, but you can get a Gbit Ethernet port on all Nvidia Shields and the latest Apple TV 128 GB.

Hi pfsi10,

our TVs support Fast Ethernet (100 Mbit/s). To use certain services or watch certain content (especially in 4K), you need the required bitrate.

Hello. No, only 100 MBit/s.
