Oh, I know all those tricks, Don. This old dog's been around the block a few times...
The box is indeed connected directly to the TV. I have a sound bar connected to the TV as well, via digital optical cable. I suppose I could use an HDMI cable and the sound bar's ARC connector, but I've always believed optical provides the cleanest pass through sound.
WiFi signal is very strong. The TVs are the only devices connecting/using the SSID from the Gateway; I have a discrete mesh network running off the Gateway's ethernet port, and all the computers/phones/doorbells/toasters in the house connect to that SSID.
When we first got Ignite TV, if we tried to view a program (primarily on SportsNet) that was available in 4K, the Ignite TV box would prompt to press info and it would switch to the 4K version. It’s has stopped doing that but I’d like it back if possible. Cables are all HDMI 2.1 compliant and the Ignite TV is connected to a Sony X900H.
