Overview
A buyer short on wall space gets a compact 4K set that still carries the full smart platform and the higher HDR formats. The panel uses a direct LED backlight behind the screen, so brightness stays even across the picture instead of fading at the edges. Four HDMI inputs and Wi-Fi cover consoles, streaming sticks and a receiver without a switch box.
Four HDMI inputs on a screen this size is unusual, and one of them handles eARC for a soundbar or receiver. Dolby Vision and Dolby Atmos support mean the streaming apps can send their better picture and sound modes straight to the set. The panel refreshes at the standard rate, so fast games and sports will not look as fluid as they do on a high refresh display.
Who it's for
Someone furnishing a spare room, a rental or a first apartment who wants one screen to handle streaming, over-the-air channels and a console. The compact panel suits close viewing distances where a larger set would overwhelm the wall. Shoppers chasing the smoothest motion for competitive gaming should spend their money on a different class of display.
Pros and cons
- Four HDMI inputs, one with eARC
- Dolby Vision, HDR10 and HLG supported
- Dolby Atmos built in
- Direct LED backlight for even brightness
- Refresh rate is 60 hertz only
- No 120 hertz gaming mode
- Stand and remote are the only accessories listed
- Contrast ratio listed as at least 1000:1
Performance notes
A direct LED backlight spreads light across the panel from behind rather than from the edges, which holds brightness more uniform and reduces the corner glow edge-lit sets can show. The motion enhancement pairs the native refresh with MEMC frame insertion, so panning shots and sports gain some smoothness without changing the panel itself. Auto Game Mode switches the set when a console signal arrives, trimming input lag for play. HDR handling covers the major formats, so the streaming apps decide how much contrast range they send.

Does the TCL 43S450R include a wall mount?
No. The listed contents are the stand, remote control, two AA batteries, power cord and quick start guide. A wall bracket is a separate purchase, and the set accepts a 200 x 200 mm VESA mount.

Four HDMI inputs are available, one of which supports eARC for a soundbar or AV receiver. There is also one USB port and one audio out port, plus built-in Wi-Fi for streaming.
