I have some confounding factors.

First of all, my house was built in 1921 so is not designed around a big screen. We have a 70" TV in our living room, but it’s over the fireplace and rough 12’ away from our faces. Experts recommend something larger for that distance, but that is the biggest thing that fits between the mantle and ceiling. We could look into one of those fancy moving TV mounts for fireplaces, but they’re quite expensive too and seem like a pain.

The second piece is that I had my retina re-attached a few years ago. Even with a strong prescription I still find it harder to see details from far away ever since.

So I prefer smaller screens closer to my face in general. I do a lot of my gaming on the Steam Deck. I watch a lot of stuff on my phone, and I have a 10" tablet I use sometimes too.

Sound is another thing. I find good quality headphones best anyone’s fancy expensive home theater setup consistently, but the tradeoff is that headphones are usually less convenient and get uncomfortable to wear after a while. Bluetooth means less battery life for my phone, wires means I’m tethered (I have an Xperia so I have a headphone jack at least).
