I bought a Hisense 55A6G 55-Inch 4K Ultra HD Android Smart TV for my lanai. It works great with Channels. It also has a remote with numeric keypad that allows direct channel number entry. Only downside is ATSC 3 doesn’t work well. The only device I have found that supports ATSC 3 is Apple TV.
Just thought I would share in case someone is looking for an affordable TV to use with Channels.
