Standout Strengths
- Strong value for a Mini-LED TV at this price point.
- Excellent for bright rooms thanks to high brightness and Quantum Dot colour.
- Very good gaming performance (4K/144Hz, two full HDMI 2.1 ports, FreeSync Premium Pro).
- Comprehensive HDR format support including Dolby Vision IQ.
- Slim modern design.

-
Limitations
- Only 180 local dimming zones on the 55-inch model → more blooming/haloing in dark scenes compared with higher TCL models (C7K/C8K).
- Not the best choice for dedicated dark-room home cinema.
- Built-in speakers are decent but benefit from a soundbar for serious movie watching.
