The 144Hz Middle Rung, with a Grade 1 Energy Label
The Z570SP's maths is simple: native 144Hz with FreeSync Premium keeps PS5, Xbox and PC smooth, while dimming is QLED full-array - stepping up to quantum-dot Mini LED and the ZRi processor is what the flagship Z670SP (successor to the Toshiba Z670NK (65/85-inch)) is for. And a Grade 1 energy label on a 75-inch screen is genuinely uncommon - real savings for households that leave the TV on. How much 144Hz actually matters over 60Hz is in our refresh-rate guide.

Frequently Asked Questions
Z570SP vs Z670SP - what changes?
Both run native 144Hz; the Z670SP steps up to quantum-dot Mini LED local dimming and the REGZA Engine ZRi processor as the flagship. The Z570SP uses QLED full-array dimming and lands at a friendlier place.
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.
