The Z670SP is Toshiba's QD-Mini LED series for 2026, and the 100-inch model is the most heavily specified size in the range. Toshiba's specification lists 720 local dimming zones, against 264 on the 85-inch, 500 nits typical brightness with peaks up to 1600 nits, and a 2.1-channel REGZA Power Audio system with a built-in subwoofer that the smaller sizes do not have. The REGZA Engine ZRi processor, a native 144Hz panel with AMD FreeSync Premium Pro, Dolby Vision IQ and a DTMB tuner for the Hong Kong version complete the package.
Key features
720 dimming zones and brighter highlights
Toshiba's specification gives the 100-inch Z670SP a Mini LED backlight behind a quantum dot panel with KSF phosphor, divided into 720 local dimming zones. That is almost three times the 264 zones of the 85-inch, so each zone covers a smaller part of this very large screen and bright objects on dark backgrounds show less halo. Brightness also rises: 500 nits typical, 1300 nits steady-state peak and 1600 nits transient peak, against 600 nits peak on the 65, 75 and 85-inch sets.
REGZA Power Audio 2.1 with a subwoofer
Toshiba reserves REGZA Power Audio 2.1 for the 100-inch size. Its specification lists two 15W front-firing speakers plus a 20W subwoofer, 50W in total, where the 65 to 85-inch sets have 40W two-channel sound with no subwoofer. Dolby Atmos decoding and Eilex sound processing are included. HDMI 1 carries eARC, so if you later add a soundbar or AV receiver, connect it there and the TV can pass Dolby Atmos through to it.
Native 144Hz with FreeSync Premium Pro
Toshiba markets the panel as native 144Hz and lists VRR from 48 to 144Hz at 4K and up to 288Hz at 2K. At this size the FreeSync rating steps up to AMD FreeSync Premium Pro, and ALLM switches to low-latency mode automatically. HDMI 3 and HDMI 4 are HDMI 2.1, so connect a PS5 or gaming PC there and keep HDMI 1 for a soundbar. HDR covers Dolby Vision IQ, Dolby Vision Game, HDR10+ Adaptive, HDR10+ Gaming and HLG, with Filmmaker Mode for films.
Delivery and wall mounting at 100 inches
Toshiba lists the carton at 2395 x 1493 x 207 mm and 80 kg gross. Many Hong Kong lifts cannot take a carton this size, so the route must be checked with us before you order: the lift car including its diagonal, every door, corridor turns and any stairs. The set weighs 60.5 kg without its stand and uses an 800 x 400 mm VESA pattern with M8 screws, so wall mounting needs a solid wall, not plasterboard, and is available as a paid service. On its feet, the stand area is 1999 mm wide.

Who it's for
- Home cinema rooms with enough seating distance for 100 inches; check yours with our TV size calculator before you order.
- Film fans who want Mini LED contrast on a very large screen, with 720 dimming zones and peaks up to 1600 nits.
- Gamers who want native 144Hz, FreeSync Premium Pro and two HDMI 2.1 inputs, with a built-in subwoofer for game soundtracks.
- Not for buyers who must have Google TV, because Toshiba has not confirmed the Hong Kong platform for this size, or for buildings whose lift cannot take a carton almost 2.4 metres long.

Frequently asked questions
How is the 100-inch different from the 85-inch Z670SP?
Toshiba's specification gives the 100-inch 720 local dimming zones against 264, 500 nits typical and up to 1600 nits peak against 400 and 600 nits, and 50W 2.1-channel sound with a subwoofer against 40W two-channel sound. It also moves up to FreeSync Premium Pro. At 60.5 kg without its stand it weighs about twice as much as the 85-inch, and it uses an 800 x 400 mm VESA pattern.
Can the carton go up in my building's lift?
Check with us before ordering. Toshiba lists the carton at 2395 x 1493 x 207 mm and 80 kg, which is too long and too tall for many Hong Kong lift cars. Send us the lift's internal width, depth, height and door size, the door widths along the route, any tight corridor turn and any stairs, and we will confirm whether delivery is possible.
Which smart platform does the Hong Kong version run?
Toshiba has not published the platform for the Hong Kong 100-inch set. Its global specification for this model lists the VIDAA-based HomeOS, while some Hong Kong retail listings describe Google TV with Cantonese voice search. If the platform or a particular app matters to you, message us and we will confirm it on the stock we hold before you order.
