We've got our hands on the budget-friendly, TCL S405, which comes with 4K, standard HDR, and runs on the Roku OS platform.
The TCL S405's bezel is fairly thin, with a glossy black finish that contrasts with the screen, coated with an anti-reflective film to reduce glare. The TV is about three inches deep — so it should look pretty good if you decide to mount it — and about 35 inches from foot to foot, assuming you’re working with the 49-inch model.
All the relevant ports and jacks are located on the rear of the TV, near the right side (the left, if you are facing the screen from the front). There are three HDMI ports — one ARC — along with one USB, optical, coaxial, composite, and a headphone/speaker jack.
The Roku remote offers shortcuts to a few popular apps on top of all the regular navigation features; it doesn’t have a headphone jack, but you can use the Roku app on your phone if you want to watch that way.
