Toshiba 75-Inch Z670SP QD-MiniLED 144Hz 4K Smart TV (Hong Kong Licensed) Overview
The Z670SP is Toshiba's 2026 flagship: quantum-dot Mini LED local dimming, native 144Hz, the REGZA Engine ZRi picture processor and a built-in subwoofer. Z670NK owners will recognise the road: same flagship line, backlight and processor both upgraded.

From Z670NK to Z670SP: What Actually Upgraded
We still stock the previous flagship, the Toshiba Z670NK (65/85-inch) - a QLED 144Hz set. This SP generation upgrades the backlight to quantum-dot Mini LED local dimming and the processor to the REGZA Engine ZRi: blacks, blooming control and highlight detail are the substantive gains, while the 144Hz-plus-FreeSync-Premium gaming spec carries straight over. Zone counts and peak nits are unpublished, so we claim none. Whether 144Hz is worth it: our refresh-rate guide.

This is Hong Kong licensed stock: warranty runs through Toshiba's official Hong Kong channel (per our warranty policy, licensed sets carry the brand's own warranty, term as published by Toshiba Hong Kong). The spec follows Hong Kong's digital broadcast standard, so aerial reception of local free channels is native and our installer tunes it for you.

Frequently Asked Questions
Z670SP or Z570SP?
Gaming spec is identical (native 144Hz, FreeSync Premium); the difference is the picture foundation: quantum-dot Mini LED with the ZRi processor here, QLED full-array with the ZR on the Z570SP. Pick by whether picture quality or value leads your budget.
How does the licensed warranty work?
Hong Kong licensed stock runs on Toshiba's official Hong Kong warranty channel, term as published by Toshiba Hong Kong - a different system from our international-version TVs.
Will it receive Hong Kong free-to-air channels over an aerial?
Yes - licensed-market spec follows Hong Kong's digital broadcast standard, so local free-to-air reception is native, and our installer tunes the channels for you.
