The Z670SP puts Toshiba's QD-Mini LED backlight, REGZA Engine ZRi and native 144Hz panel into a 55-inch frame only 55 mm deep without its stand. That makes it the pick for a bedroom, study or smaller living room where you still want Mini LED contrast and full gaming support. It is the smallest size of Toshiba Hong Kong's 2026 Mini LED line, which runs from 55 to 100 inches.
Key features
QD-Mini LED backlight
Mini LEDs are far smaller than conventional backlight LEDs, so more of them fit behind the panel and light can be controlled more finely. Paired with quantum-dot colour covering at least 90% of DCI-P3, the 55-inch model is rated at 400 nits typical and 600 nits peak brightness. Closer seating in a small room makes halo around subtitles and bright objects easier to notice, which is where finer backlight control helps.
REGZA Engine ZRi with a full HDR list
Toshiba's top REGZA Engine ZRi handles AI upscaling, scene analysis and HDR tone mapping, with REGZA Intelligence adjusting picture and sound to the content. HDR support is broad: HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, Dolby Vision, Dolby Vision IQ and Dolby Vision Game.
Native 144Hz with VRR and FreeSync Premium
The panel refreshes natively at 144Hz. VRR, AMD FreeSync Premium and ALLM are all supported, and four HDMI inputs mean a console, a PC and a soundbar can stay connected. Toshiba lists eARC on HDMI for sending Dolby Atmos to a soundbar.
Front-firing four-driver sound
The 55-inch Z670SP uses four drivers in a 2.0-channel front-firing layout, rated 2 x 10W + 2 x 10W, with Dolby Atmos and Eilex processing. Sound is aimed at the viewer rather than down at the wall or TV cabinet, which keeps dialogue clear at moderate volume in a bedroom.

Who it's for
- Film fans watching in a dark bedroom or study, where Mini LED backlight control shows most and a 55-inch screen fits the room — check with our size calculator.
- Console and PC gamers who want native 144Hz, VRR and FreeSync Premium together with Toshiba's top picture processing.
- Wall-mount installs where a slim 55 mm body sits closer to the wall.
- Not the best fit for bright rooms with the curtains open most of the day. Ambient light hides much of the Mini LED advantage, and the Z570SP has the same 144Hz gaming features.

It also has four HDMI inputs and a four-driver speaker system.
Does the 55-inch Z670SP have a subwoofer? No. Toshiba lists the 55-inch model as a 2.0-channel system with four front-firing drivers. Only the 100-inch Z670SP has a 2.1-channel layout.
