TCL 55S21 55-Inch 4K Smart TV with Mount

The TCL 55S21 is a 55-inch 4K Ultra HD Smart TV that combines HDR support with Dolby Digital Plus audio to deliver an enhanced home entertainment experience. The 4K resolution produces sharp, detailed images across the large screen, while HDR processing expands the contrast and color range on compatible content from streaming services and media players. With four HDMI inputs — including one with ARC support — it accommodates a gaming console, streaming stick, Blu-ray player, and soundbar simultaneously without constant cable swapping.

A notable inclusion with this model is a free wall mount in the box, which saves buyers the cost and hassle of sourcing one separately. It is important to note that a traditional base stand is not provided, so the wall mount or a third-party stand is necessary. The TV supports both Amazon Alexa and Google Assistant for voice-controlled operation, and built-in Wi-Fi enables direct access to streaming apps. The 60Hz refresh rate handles standard content well, though viewers who watch a lot of live sports or play fast-paced games may notice the limitations compared to higher refresh rate panels.
