TCL is expanding its Designer Series television lineup in the U.S. following IFA, adding the A300L 4K QLED and A400U 4K QD-Mini LED families. Both run Google TV, include flush wall mounts, and can turn the screen into digital artwork when movie night is over.
The new models take slightly different approaches to the wall-mounted TV concept. The A300L puts more attention on the framed-art aesthetic, including an ultra-matte screen and interchangeable frame. The A400U shifts toward higher-end display hardware with QD-Mini LED backlighting and TCL’s Halo Control System.
TCL A300L Puts the Focus on the Frame

The A300L is a 4K QLED Google TV designed to sit nearly flat against the wall. The 55- and 65-inch models measure 1.1 inches deep without a stand, with the larger sizes remaining close to that figure. TCL includes an ultra-thin wall mount in the package, while table stands are sold separately.
Its ultra-matte anti-glare screen is meant to make artwork look less like an image displayed on a television. TCL pairs that with an off-white bezel and an included light wood magnetic frame that can be swapped without much fuss. Owners looking for another style can use compatible handcrafted frames from Laredo Factory Frames.
Underneath the décor-friendly exterior is a 4K QLED panel with a 144Hz refresh rate. HDR support covers Dolby Vision, HDR10+, HDR10, and HLG. Audio comes from two speakers delivering 20 watts total with Dolby Atmos processing, and connectivity includes four HDMI ports, one with eARC.


The A300L is available now in three sizes:
- 55-inch 55A300L: $1,099
- 65-inch 65A300L: $1,499
- 75-inch 75A300L: $1,999
An 85-inch version is slated to arrive later, though TCL has not provided pricing.
A400U Trades QLED for QD-Mini LED

The A400U moves farther up the display ladder with TCL’s QD-Mini LED technology. Its Halo Control System combines several display and backlight technologies, including a high-contrast HVA panel, a 23-bit backlight controller, and dynamic light processing intended to reduce visible haloing around bright objects. Local Dimming Pro+ adjusts the backlight according to on-screen content.
The panel runs at a native 144Hz refresh rate, with HDMI 1 and HDMI 2 supporting 4K at 144Hz. HDMI 1 handles eARC, while the remaining HDMI inputs support up to 4K/60Hz. HDR formats include Dolby Vision, HDR10+, HDR10, and HLG, with Dolby Atmos and DTS:X among the supported audio formats.


TCL lists the A400U at $999 for 55 inches, $1,499 for 65 inches, $1,999 for 75 inches, and $2,499 for 85 inches. Interestingly, TCL’s specification sheet includes a 98-inch A400U as part of the family, but pricing and U.S. availability for that size were not included in the announcement.
TVs That Double as Wall Art
Both Designer Series families include TCL’s curated Art Library, AI-generated artwork, multiple digital matte options, and a personal photo gallery mode. That gives buyers several ways to fill a large blank rectangle when the TV is idle, rather than leaving a dark slab hanging above the furniture.
With Google TV handling streaming and the flush wall mount included, the A300L and A400U are aimed squarely at buyers who want a television to behave more like part of the room rather than equipment bolted onto it.
