The next-gen displays comprise of the flagship HD 5K monitor, the 34-inch curved monitor, the 25-inch display with QHD resolution, and the 27-inch Ultra HD 4K monitor. One of the key features of the A400 Series is Art Gallery Mode, which allows the TV to display artwork on the screen. Both models use TCL's QLED technology, which can display over a billion colors and improve brightness for clearer picture quality. The smart TV features a 55-inch QLED display with 4K resolution and a 120Hz refresh rate. This automatically switches the display to black when the user steps away to reduce burn-in risk.
