Weve had a similar setup for nearly 10 years and its fricken great. We built a low spec computer using old parts from our desktops, hooked it up to our tv via hdmi, and plugged in a wireless keyboard with built in trackpad to act as the remote. We get all the same AD blocking and content access as a desktop because, you know, its a desktop but in the livingroom. My personal favorite is using a second account on discord to pull up streams on the tv from the couch while joining on my phone via my primary account for voice.
