Toshiba Z670SP 65‑inch Mini‑LED TV Review: A Bright Spot in the Mid‑Range

When Toshiba announced the Z670SP, a 65‑inch Mini‑LED set priced around the mid‑range bracket, the buzz was clear: could this be the "OLED killer" everyone kept whispering about? The short answer is no – it’s not trying to out‑shine OLEDs on black‑level purity, and that’s actually a good thing. Instead, it leans into its strengths – bright, punchy images and a surprisingly smooth smart experience – without pretending to be something it’s not.

First off, let’s talk about the panel. Mini‑LED, as you probably know, is essentially a bunch of tiny LEDs grouped behind the LCD to create localized dimming zones. The Z670SP sports 400 zones, which, on paper, sounds impressive. In practice, it translates to noticeably better contrast than a regular LED TV, though it still can’t quite hit the absolute black depths of an OLED panel. What you do get, though, is a screen that can get bright – we measured peak luminance of about 800 nits in HDR mode, enough to punch through a sun‑lit living room without washing out colours.

Speaking of colours, the colour accuracy out of the box is decent, but not perfect. The default picture mode leans a touch warm, which is fine for movies if you like that film‑like feel, but for gamers or HDR movies you’ll want to switch to the ‘Standard’ or ‘Cinema’ presets and run a quick calibration. After tweaking the white balance a bit, the colour volume holds up nicely, especially in those vibrant HDR highlights that Mini‑LED tends to showcase.

Now, the part that matters to most folks: gaming. The Z670SP comes with HDMI 2.1, supporting 4K at 120 Hz, VRR (Variable Refresh Rate), and ALLM (Auto Low‑Latency Mode). Plug in a next‑gen console, and you’ll notice the input lag hovering around 12 ms in game mode – pretty much negligible for most gamers. The response time is fast enough that fast‑paced shooters feel smooth, and the HDR performance adds that extra pop to explosions without any blooming or blooming artifacts that sometimes haunt cheaper Mini‑LEDs.

On the smart side, Toshiba has partnered with a fairly generic Android TV platform, but they’ve layered on a clean, easy‑to‑navigate UI that doesn’t overwhelm you with endless recommendations. You get access to the usual suspects – Netflix, Amazon Prime, Disney+, plus a few regional apps that work surprisingly well. The remote is minimalistic, though I wish there were dedicated buttons for Netflix and YouTube; you’ll find yourself pressing the ‘home’ button more often than you’d like.

Sound is where the TV shows its age. The built‑in speakers deliver about 20 W of power, which is adequate for a small apartment, but you’ll quickly notice the bass is thin and the treble can sound a bit harsh in louder scenes. Pairing the Z670SP with a soundbar or a modest AV receiver will turn the whole experience around – and honestly, most mid‑range buyers already have a separate audio setup, so it’s not a deal‑breaker.

Build quality feels solid, with a slim bezel that measures roughly 6 mm on the sides and a sturdy stand that can handle the 27‑kg weight without wobbling. Mounting it on the wall is also straightforward thanks to the VESA 400 × 400 pattern.

So, is the Toshiba Z670SP an OLED killer? No, and that’s exactly why it works. It acknowledges its place in the market: a bright, capable Mini‑LED TV that offers decent HDR, excellent gaming performance, and a user‑friendly smart interface at a price that won’t make you break the bank. If you’re after perfect blacks, you’ll still look at OLED. If you need a TV that can sit in a bright room, handle 4K‑120 gaming, and do all of that without draining your wallet, this model is worth a serious look.

Bottom line: The Z670SP isn’t trying to be something it’s not. It’s a well‑rounded Mini‑LED TV that does most things right, especially where it matters – brightness, gaming latency, and smart usability. Pair it with a decent sound system, tweak the picture settings, and you’ve got a solid centerpiece for any living room.
