Toshiba 100" Z670 Series Review

The Toshiba 100Z670R is a 100-inch Mini-LED QLED TV built for gamers. It offers a native 144Hz refresh rate, excellent HDR support, and deep blacks, all for a competitive price. Just be ready to add a soundbar, as the built-in audio doesn't match the quality of the picture.

Looking for a massive 100-inch TV that doesn't sacrifice gaming performance? The Toshiba Z670 Series is a 100-inch Mini-LED QLED TV that's built to be a gaming powerhouse. For around $2500, you get a native 144Hz panel, AMD FreeSync Premium, and a full suite of HDR formats, all wrapped up in a screen that's basically a wall of entertainment. It runs on Fire TV, so you've got Alexa built right in, and it promises deep blacks and bright highlights thanks to its Mini-LED backlight with local dimming. If you're a gamer or a movie buff with a big room to fill, this is a TV that's definitely on the radar.

This TV is built for speed. That native 144Hz refresh rate puts it in the top tier for gaming TVs, and in our testing, motion handling is incredibly smooth with next to no blur. The input lag is low enough that you won't feel held back in fast-paced shooters or racing games. For picture quality, the Mini-LED backlight delivers. Blacks are deep and inky, and highlights in HDR content pop with intensity. It scores in the 89th percentile for picture quality, which means it's one of the best-looking LED TVs you can get. The HDR support is actually the best we've seen, hitting the 100th percentile with Dolby Vision IQ and HDR10+ Adaptive. That means no matter what you're watching, the TV is optimizing the picture in real-time. The audio, however, is a bit of a letdown. Despite the fancy 'Power Audio Pro' name and bass woofer, it lands in the 27th percentile. It gets loud, but it lacks the clarity and depth of a good soundbar setup.

At $2500 for a 100-inch screen with these specs, the value proposition is actually pretty strong. You're paying for the massive canvas and the top-tier gaming/HDR features. You won't find many 100-inch TVs at this price, and certainly not with a 144Hz panel. The trade-off is that you're getting a Toshiba, not a Sony or Samsung, and some areas like audio and general connectivity feel like they were cut to hit that price point. But if screen size and gaming performance are your top priorities, the money goes a long way here.

This TV sits in a weird and interesting spot. The most direct competitor is something like the TCL QM6K 85-inch QD Mini-LED. It's smaller but often brighter and might have better smart TV software (Google TV). The Toshiba fights back with a bigger screen and that crucial 144Hz refresh rate. If you care more about perfect blacks than raw size, the 77-inch LG OLED C5 is a similar price and will destroy it in contrast and viewing angles, but it maxes out at 120Hz and isn't as bright for HDR. Then there's the Samsung Neo QLED 65-inch. It's a lot smaller, but it's often brighter, has better smart features, and better audio. The Toshiba's play is simple: give up some polish in other areas to be the biggest, fastest screen you can get for the money.

Skip this TV if you prioritize built-in audio quality or watch in a very brightly lit room. The speakers are a weak point, and while it gets decently bright, it's not a brightness champion. Also, if you don't care about high refresh rate gaming, you might find better overall picture refinement in a smaller OLED or a higher-end Samsung Mini-LED. And obviously, if you don't have a wall that can fit a 100-inch TV, this isn't for you.

So, should you buy the Toshiba 100Z670R? If you are a serious gamer who wants a truly massive screen and your budget tops out around $2500, this is an easy yes. The 144Hz performance and excellent HDR make it a blast for both PC and console gaming. Just budget for a soundbar immediately. If you're not a gamer, or if your room is very bright, or if you want the absolute best picture quality regardless of refresh rate, you should look at those OLED or higher-end Mini-LED alternatives. This TV makes very specific trade-offs for a very specific buyer.
