What "HSR 120Hz" Actually Means
The official spec itself says "HSR 120Hz" - HSR is a high-speed refresh mode that smooths motion, while the panel's native rate is 60Hz; that is not the same thing as a native 120Hz panel. For sport and movies, 60Hz plus HSR is plenty; if you game first and want true 144Hz, look at the Z570SP or Z670SP instead. How refresh rates really affect the picture is covered in our refresh-rate guide. For a simpler entry point there is the Toshiba C350NK.
Licensed Stock: Toshiba Official Warranty
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.
