TCL has expanded its flush-mounted Designer Series television lineup in the United States with two new families: the A300L 4K QLED Designer Series and the A400U 4K QD-Mini LED Designer Series.
Announced following IFA, both ranges are designed to blend into modern interiors while offering smart-TV functionality through Google TV. Each model also includes a flush wall mount in the box, making it easier for buyers to create a wall-art-style entertainment setup.
TCL A300L: A 4K QLED TV Designed to Look Like Wall Art
The TCL A300L is built for users who want a television that integrates discreetly into their living spaces. Measuring just 1.1 inches deep, the TV features a slim profile and an ultra-matte anti-glare display designed to reduce reflections.
The A300L comes with an off-white bezel and includes a light wood magnetic frame that can be attached or removed within seconds. This allows users to change the appearance of the television to match their room’s décor.
The display supports a 144Hz refresh rate, making it suitable for sports viewing, fast-paced content and gaming. It also supports Dolby Vision, HDR10+ and HLG for enhanced contrast, color and HDR performance.
For sound, the television features a 20W audio system with Dolby Atmos support. Connectivity includes four HDMI ports, one of which supports eARC for compatible soundbars and home theater systems.
The A300L is currently available in 55-, 65- and 75-inch sizes, while an 85-inch version is expected to arrive later.
TCL A400U: QD-Mini LED Performance in a Designer TV
The A400U is aimed at viewers who want a more advanced display system without sacrificing the minimalist appearance of a flush-mounted television.
It uses QD-Mini LED technology, combined with TCL’s Halo Control System and Local Dimming Pro+ technology. These features are designed to improve brightness control, contrast and the separation between bright and dark areas of an image.
The A400U also includes a native 144Hz refresh rate. HDMI 1 and HDMI 2 support 4K resolution at 144Hz, making the television particularly relevant to gamers using compatible PCs or gaming consoles.
HDR support includes Dolby Vision and HDR10+, while DTS:X passthrough is available for compatible audio equipment.
The A400U is offered in 55-, 65-, 75- and 85-inch screen sizes.
Google TV and Built-In Art Features
Both the A300L and A400U run Google TV, giving users access to supported streaming services, apps and personalized content recommendations.
The televisions also include several features designed to make them function as decorative displays when they are not being used for conventional viewing.
These features include:
- A curated art library
- AI-generated artwork
- Multiple art matte options
- A personal photo gallery mode
- Flush wall mounting included in the box
The combination of customizable frames, art displays and flush-mount installation allows the TVs to serve as part of a room’s décor rather than appearing as traditional standalone screens.
