I’m designing a big living room with pool table. I want to add a 2nd tv near the pool table for sports or for mirroring what’s on the main tv. For cable or OTA, this seems simple: use an HDMI splitter that goes to each. But how about streaming? If the main (smart) tv is the streaming device, how can I duplicate its output to the 2nd tv? Do they come with hdmi output also?
