The Z670SP is Toshiba's QD-Mini LED series for 2026: a quantum dot panel lit by a direct Mini LED backlight, driven by the REGZA Engine ZRi processor, with a native 144Hz panel for gaming. At 85 inches Toshiba's specification lists 264 local dimming zones, up from 160 on the 65-inch, with 400 nits typical and 600 nits peak brightness and support for Dolby Vision IQ, HDR10+ and HLG. Sound comes from front-firing speakers with Dolby Atmos and Eilex processing, the Hong Kong version has a DTMB tuner, and the set carries a Grade 2 Hong Kong energy label.
Key features
QD-Mini LED with 264 zones
Toshiba's specification for the 85-inch Z670SP lists a Mini LED backlight behind a quantum dot panel with KSF phosphor, split into 264 local dimming zones. That is 104 more zones than the 65-inch, which matters on a screen this wide: each zone covers a smaller area, so bright objects on dark backgrounds bloom less. Typical brightness is 400 nits, peaking at 600 nits, and the listed native contrast ratio is 8500:1.
REGZA Engine ZRi and HDR
The REGZA Engine ZRi handles upscaling, noise reduction and frame-by-frame HDR tone mapping, tuned by Toshiba's REGZA picture team. HDR support covers Dolby Vision IQ, HDR10+ Adaptive, HDR10 and HLG, and Filmmaker Mode turns the processing down when you want the picture as the director graded it. For broadcast, Toshiba's specification lists a DTMB digital tuner for the Hong Kong version, with two RF aerial inputs.
Native 144Hz gaming
The panel is specified for native 144Hz, with VRR from 48 to 144Hz at 4K and up to 288Hz at 2K, plus AMD FreeSync Premium and ALLM. Toshiba lists four HDMI inputs: HDMI 3 and HDMI 4 are HDMI 2.1, and HDMI 2 carries eARC. Connect a PS5 or gaming PC to HDMI 3 or 4 and a soundbar to HDMI 2 so both run at full capability. Game Mode Pro and Game Deck keep picture and game settings within reach.
Delivery and wall mounting at 85 inches
Toshiba's specification gives the panel as 55 mm deep and 30.0 kg without its stand, or 31.0 kg on its two feet, with a 600 x 400 mm VESA pattern. The carton measures 2090 x 1280 x 189 mm and weighs 43 kg, so check the lift car, doors and corridor turns before ordering, and tell us about any walk-up floors. Plasterboard false walls need checking before mounting, and wall mounting is available as a paid service.

Who it's for
- Viewers moving up to 85 inches who want Mini LED contrast; check your seating distance with our TV size calculator before you order.
- Console and PC gamers who want native 144Hz, VRR up to 288Hz at 2K and two HDMI 2.1 inputs.
- Anyone planning a wall mount: at 30.0 kg without the stand and with a standard 600 x 400 mm VESA pattern, it suits common heavy-duty brackets on a solid wall.
- Not for buyers who must have Google TV, because Toshiba has not confirmed the Hong Kong platform for this size; check with us before ordering if the platform matters.

Frequently asked questions
How is the 85-inch different from the 65-inch Z670SP?
Toshiba's specification gives the 85-inch 264 local dimming zones against 160 on the 65-inch. Brightness (400 nits typical, 600 nits peak) and the 40W front-firing audio system are listed the same for both. The 85-inch weighs 30.0 kg without its stand and uses a 600 x 400 mm VESA pattern, so check your wall and bracket before ordering.
Does it receive Hong Kong digital TV channels?
Toshiba's specification lists a DTMB digital tuner for the Hong Kong version, which is the standard used for Hong Kong digital terrestrial broadcasts, and the set has two RF aerial inputs. Connect it to the building's aerial socket and run a channel scan; no set-top box is needed for local digital terrestrial channels.
Which smart platform does the Hong Kong version run?
Toshiba has not published the platform for the Hong Kong 85-inch set. Its global specification for this model lists the VIDAA-based HomeOS, and the Australian version also runs VIDAA, while some Hong Kong retail listings describe Google TV. 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.
