I regret buying a smart TV — I should’ve used this setup instead

My current TV is a TCL C728, which has a 55-inch QLED panel. I bought it back in 2020 or thereabouts (can’t remember the exact year), and I’ve been using it to watch content and play video games. When I got this TV, it was perfect because, as you can imagine, upgrading to a 4K 55-inch TV from a 32-inch model made an instant difference to my watching experience. My old TV was a Samsung with 1080p resolution (aka FHD), and while I could watch content online, the picture quality wasn’t the best.
