I block my old TCL Roku TV from accessing the internet through my router. It works fine as an HDMI display.
Antenna works good enough for the 3 PBS channels I like, even though their antenna is 50 miles away. Just one of those cheap $30 rabbit ears. What's interesting is that the signal bounces off a south wall,through the N patio door, so when anyone moves in the path, the signal is garbled. Also, depending on the station, it must sometimes be repositioned. I enjoy the retro feel of that.
