{"product_id":"tcl-55-inch-a400m-premium-qd-mini-led-4k-google-tv-hong-kong","title":"TCL 55-Inch A400M Premium QD-Mini LED 4K Google TV","description":"\u003cp\u003eMini LED is only as good as the control behind it, and the A400M is the TCL model where that control comes with a published figure: 112 dimming zones for the 55-inch, set behind an HVA panel in a flat-back cabinet just 39.9mm deep. Add a 144Hz native panel, four HDMI 2.1 inputs and ONKYO-branded sound, and you have a 55-inch that suits a slim wall mount in a bedroom as well as a gaming corner.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003ch3\u003e112 dimming zones and 600 nits\u003c\/h3\u003e\n\u003cp\u003eTCL's Hong Kong spec sheet lists 112 local dimming zones and a brightness rating of 600 nits for the 55-inch A400M. Zone dimming darkens the backlight behind dark parts of the picture while keeping bright areas lit, which is what lifts contrast in night scenes beyond a panel-only QLED set. TCL's halo-control design uses condensed micro-lenses and Micro-OD optics to keep light from spilling around bright objects.\u003c\/p\u003e\n\u003ch3\u003eQD-Mini LED over an HVA panel\u003c\/h3\u003e\n\u003cp\u003eThe backlight sits behind an HVA panel rated at 5000:1 native contrast, with a quantum dot layer covering up to 93% of DCI-P3. HDR10+ and HLG are supported; HDR10+ carries dynamic metadata, so brightness mapping adjusts scene by scene. Picture processing is handled by TCL's TSR AiPQ processor.\u003c\/p\u003e\n\u003ch3\u003e144Hz native, 288Hz VRR and FreeSync Premium Pro\u003c\/h3\u003e\n\u003cp\u003eThe panel runs at 4K 144Hz natively, and TCL's Game Accelerator offers 288Hz at 1080p, with a VRR range of 48–288Hz. Four HDMI 2.1 inputs, eARC and AMD FreeSync Premium Pro certification mean tear-free variable refresh rate gaming from a PS5, Xbox Series X or PC, and Game Master puts frame rate and VRR status on screen.\u003c\/p\u003e\n\u003ch3\u003e39.9mm flat-back cabinet and ONKYO sound\u003c\/h3\u003e\n\u003cp\u003eThe flat unibody back is 39.9mm deep at 55 inches, so on a slim bracket the set sits close to the wall — useful in a bedroom or corridor where a protruding TV gets in the way. Audio is an ONKYO sound system in a 20W 2.0-channel layout with Dolby Atmos, DTS:X and DTS Virtual:X. Google TV with Gemini, AirPlay 2, Wi-Fi 5, Bluetooth 5.4 and a built-in DTMB tuner complete the package.\u003c\/p\u003e\n\u003cp\u003eDeciding between 55 and 65 inches?
