The 55-inch A400 Pro NXTVISION combines a frame-inspired design and matte screen with QD-Mini LED, 112 local-dimming zones and a native 144Hz panel. Google TV, TSR AiPQ processing and an ONKYO 2.0 system support its everyday television role alongside art display.
What to check before choosing
This is A400 Pro, not A400M. The mobile floor stand is sold separately; the included tabletop stand and wall-mount accessories depend on shipment and region. Confirm the actual box contents before planning installation. Art content, account requirements and licensing can change. The matte finish is not a promise of zero reflections.

Google TV, apps and connections
Streaming, casting and voice features require compatible devices, internet access and relevant accounts. Some services need subscriptions. Confirm Hong Kong broadcast reception and apps such as myTV SUPER or Now TV for the supplied version; this listing does not promise every platform is preinstalled or available. Check the HDMI input, source format and cables for your console, PC or soundbar.
Room fit, delivery and warranty
Screen size is a diagonal measurement, not chassis or carton width. Measure the cabinet, stand footprint, ventilation, cable clearance and delivery route. A professional should assess wall loading, wall material, VESA screws and installation. Stock, regional version and warranty follow the actual supply and warranty card; no universal three-year term is assumed. Delivery and installation charges are confirmed separately.
Review the TV size and viewing-distance calculator, delivery, installation and recycling arrangements and TV warranty policy, or compare TCL televisions. Kwun Tong premises are for stock and arranged collection only, not demonstrations or TV testing; confirm before travelling.
Specification and image notes
Details are checked against the Hong Kong page with the selected size. Brightness, gamut and picture-performance figures are manufacturer specifications or laboratory claims, not Elechid measurements. Features can change with firmware, source, region and batch. Images are manufacturer product illustrations associated with this model; some are shared across sizes. Actual stands and included accessories follow the supplied package.
