Fifty-five inches is where a lot of Hong Kong bedrooms and smaller living rooms top out, and the M550NK is Toshiba's quantum-dot answer for that space. It is a 60Hz QLED with Dolby Vision IQ, Dolby Atmos through a 2.1-channel speaker system with its own subwoofer, and Google TV — licensed stock with the local digital tuner built in. It is a film-and-drama set, not a gaming one, and we say so plainly below.
Key features
Quantum-dot colour on a 55-inch panel
The quantum-dot layer widens the colour range beyond a standard LED set; Toshiba Hong Kong's spec sheet puts the 55-inch model at 122% of BT.709. Toshiba also lists multi-zone backlight control, which helps dark scenes avoid the flat grey look of a uniformly lit backlight.
Dolby Vision IQ and HDR10+
Both dynamic HDR formats are supported, so Netflix and Disney+ titles mastered in Dolby Vision play in that format, and Dolby Vision IQ adjusts the picture to the light level in your room. That matters in a bedroom, where the set is often watched with only a bedside lamp on.
2.1 sound with a built-in subwoofer
The 55-inch M550NK carries two 10W main speakers plus a 20W subwoofer, with Dolby Atmos decoding. For a bedroom or a compact living room that is often enough on its own, without a soundbar under the screen.
60Hz panel, with HSR 120Hz stated honestly
Toshiba's own spec lists the refresh rate as "60 Hz (HSR 120Hz)". HSR is a high-speed refresh mode for smoother motion; the panel itself is native 60Hz. Broadcast TV and streaming are delivered at 60Hz or below, so that is fine for viewing. If you want a PS5 to run at 120Hz, look at the 144Hz Z-series instead. More in our refresh-rate guide.

Who it's for
- Bedrooms and smaller living rooms where 55 inches is the largest screen that fits — use our size calculator to check your seating distance.
- Drama, film and sport viewers who want Dolby Vision and quantum-dot colour at the entry end of Toshiba's range.
- Rooms without space for a soundbar: the built-in 20W subwoofer gives the set usable bass by itself.
- Not for gamers who want 120Hz from a console. The panel is native 60Hz; the Z570SP and Z670SP have native 144Hz panels.

Frequently asked questions
Is the M550NK a 120Hz TV? No. Toshiba lists it as 60Hz with an HSR 120Hz mode. HSR smooths motion processing, but the panel refreshes at 60Hz, so a console will not output 120Hz to it.
Does it have a subwoofer? Yes. The 55-inch model has two 10W main speakers and a 20W subwoofer in a 2.1-channel layout, with Dolby Atmos.
Will it receive Hong Kong free-to-air channels? Yes. This is Hong Kong licensed stock with the local digital terrestrial tuner built in, so free-to-air channels come in through the aerial socket with no set-top box.
