TCL launches 32X3B OLED+ with 4K 240Hz and 480Hz mode, 27X3B offers 1440p 280Hz
© TCL TCL has launched the 32X3B and 27X3B OLED+ gaming monitors in China. Both models use fourth-generation WOLED panels, with the 32-inch version supporting up to 4K at 240Hz and the 27-inch model running at 2560×1440 and 280Hz.
Fourth-generation WOLED panels with four-layer structure
The fourth-generation WOLED panel uses a four-layer red, blue, green and blue tandem structure. TCL claims this improves brightness, color reproduction and panel lifespan compared with the previous three-layer design. The company lists peak HDR brightness of 1,500 nits, full-screen brightness of 335 nits, native 10-bit color and 99.5% DCI-P3 coverage. Both monitors carry VESA DisplayHDR True Black 500 certification.

© TCL The 32X3B supports two operating modes. It runs at 3840×2160 and 240Hz at its native resolution, or 1920×1080 and 480Hz for games where refresh rate takes priority. The smaller 27X3B uses a native 2560×1440 panel with a 280Hz refresh rate. It also supports black frame insertion, which TCL combines with the quoted 0.03ms OLED response time to reduce visible motion blur.
Low-reflection coating and B&O audio
TCL applies a circular-polarization layer to the glossy panels, reducing the listed reflectivity to 1.1%. The monitors also use a revised pixel arrangement intended to reduce colored edges around text, an issue found on some OLED subpixel layouts. Both models include front-facing speakers tuned with Bang & Olufsen and use a 6.4mm-thick metal enclosure.
© TCL The 32-inch model includes two HDMI 2.1 ports, DisplayPort 2.1 and USB-C with up to 90W power delivery. This allows a connected notebook to receive power while sending a display signal through the same cable. International connector configurations may differ if TCL releases the monitors outside China.
TCL has priced the 27X3B at CNY 3,699, equivalent to around $546. The 32X3B costs CNY 6,499, or approximately $960. Preorders have started in China with a three-year replacement warranty. TCL has not confirmed release dates or official prices for the US or European markets.
