<\/p>\nToshiba markets the Z870 series to provide consumers with a high-quality cinematic and gaming experience.\u00a0These TVs are equipped with Mini LED panels with quantum dots and a built-in REGZA Engine ZRi chip, allowing you to reproduce first-class images with resolutions up to 4K with support for Dolby Vision and HDR 10+.<\/p>\n
For gaming enthusiasts, the TV offers adaptive Variable Refresh Rate (VRR) up to 144Hz, as well as features such as AMD FreeSync Premium, Auto Low Latency Mode (ALLM), and IMAX Enhanced capabilities.\u00a0In our Toshiba 55Z870 4K HDR Mini LED review, we’ll talk about the main features of the TV that make it an attractive purchase.<\/p>\n
<\/p>\n
<\/p>\n
The Toshiba 55Z870 TV model on the market occupies a unique position, targeting an audience looking for devices that are slightly above the average level, but still not reaching the very top.\u00a0This device has an elegant appearance with premium notes that will look appropriate in any living space interior.\u00a0The screen’s boundaries are defined by a sleek metal frame, giving it a sophisticated look.\u00a0The bottom panel hides the two front-facing speakers, making it significantly wider.<\/p>\n
Despite the modern design, the dimensions of the TV are represented by a relatively wide profile, reaching approximately 8 cm at the widest part. This is worth considering if you want to integrate the TV into the interior using wall mounting.\u00a0It will require a special VESA 400 x 400 bracket, which is a standard requirement for devices with a screen diagonal of 55 inches.<\/p>\n
Some of the TV’s connectors are directed perpendicular to the back panel, so it may not be possible to move the case close to the wall.\u00a0The design rests on a pair of flat metal legs that fit vertically into the bottom of the TV.\u00a0The distance between these Two Way Stand supports can be changed when you need to use narrow TV furniture.\u00a0For discreet routing of cables, appropriate clips are provided on the legs.<\/p>\n
The Toshiba Z870 TV remote control is similar to the one that comes with\u00a0the Toshiba Z670M\u00a0.\u00a0This classic black box has 12 buttons dedicated to video services, a four-way joystick for menu navigation, and a block of number buttons.\u00a0The case is ordinary, plastic, with a slight thickening near the battery compartment.\u00a0What’s nice is that there is a physical button for switching signal sources.<\/p>\n
<\/p>\n
The Mini LED backlight of the Toshiba Z870 series is accompanied by Quantum Dot technology, which uses specialized local dimming algorithms.\u00a0Hundreds, if not thousands of tiny, high-density mini-LEDs are controlled much more precisely than any previous FALD system.<\/p>\n
But keep in mind that while mini-LED technology is vastly superior to any other LCD backlight system, it does not completely solve the problem of backlight bleed.\u00a0And this still largely depends on the number of zones a particular panel has, as well as how effective the dimming algorithms are.\u00a0Toshiba has not yet disclosed the parameters, but the similar TCL C755\u00a0TV\u00a0has 384 of them, and\u00a0the Hisense U8K\u00a0has 672.<\/p>\n
Peak brightness in SDR mode in the 10% window shows a value of 1630 nits, which is a fantastic parameter.\u00a0With such high brightness, this TV has no problem handling glare even in the brightest rooms.\u00a0In the HDR brightness test in a 10% window, we measure almost 1800 nits in peaks.\u00a0This is a TV that will make any HDR content look as good as it should.<\/p>\n
Like many Hisense and TCL options, the Toshiba 55 Z870 TV supports all HDR formats.\u00a0That is, it works not only with basic HDR10, but also with HLG, which we mostly see in streaming content, as well as HDR10+ and Dolby Vision, which use dynamic metadata to produce much better image quality.<\/p>\n
<\/p>\n
The use of a VA panel means the Z870 doesn’t have very good viewing angles.\u00a0VA matrices\u00a0usually\u00a0have problems with this, so it’s not a problem with this TV in particular.\u00a0Some manufacturers tend to use extra layers to solve this problem, but the Toshiba Z870 TV doesn’t seem to use any such technology.<\/p>\n
The TV pleases with deep blacks and bright highlights.\u00a0The native contrast is very high compared to even other VA panels.\u00a0And thanks to the local dimming feature, the TV’s contrast increases exponentially.\u00a0The result is very deep blacks, as any top-tier TV should have.<\/p>\n

<\/p>\n
By using Quantum Dot technology, the TV supports a wide color gamut and thus displays more accurate and realistic colors.\u00a0In tests, it achieves approximately 98% coverage of the DCI-P3 color space.\u00a0In the wider REC.2020 color space, 79% coverage can be achieved.\u00a0These are big numbers.<\/p>\n
<\/p>\n
Before calibration, the TV shows exceptional color accuracy.\u00a0Most colors manage to stay below the DeltaE 3.0 limit, with only blue colors exceeding it.\u00a0Everything can be solved with a small adjustment of the white balance, although on the other hand, the color temperature is almost ideal.\u00a0In principle, even the settings \u201cout of the box\u201d of the TV are excellent.<\/p>\n
Color gradients are good too.\u00a0Sometimes only minor streaking is noticeable in most darker shades, but it’s really minor.\u00a0There is also a digital noise reduction feature (smooth gradation) in case you find the banding annoying.\u00a0But if you turn it on, some details will be lost, and in general it’s best not to use this feature too often.<\/p>\n
The 55Z870 TV supports not only 120Hz, but also 144Hz, which is gradually becoming the standard for many high-end TVs.\u00a0In terms of motion, the TV behaves very well, with very little blur in fast-moving scenes.\u00a0Obviously, this is the result of the fast response of the matrix.<\/p>\n
But this also has a negative effect, as low frame rate content sometimes introduces stuttering, which can only be reduced by enabling motion interpolation.\u00a0The TV can also de-judder 24p or 60p video, which is great for any type of content.\u00a0Obviously, using very aggressive interpolation settings will result in a soap opera effect, so don’t get carried away.<\/p>\n
<\/p>\n
The TV officially supports a frequency of 144 Hz, and in 1080p and 4K resolutions the input lag is 5 ms and 5.5 ms, respectively.\u00a0Note that both PlayStation 5 and Xbox Series X support frequencies up to 120 Hz.\u00a0Therefore, to enjoy higher frame rates, you will need a high-end gaming PC.<\/p>\n
The Z870 series features Auto Low Latency Mode (ALLM).\u00a0There is a Game Deck to help gamers.\u00a0This is a special menu where you can find valuable information during the game.\u00a0Information such as FPS, HDR, VRR and other settings are available at the touch of a button.\u00a0By the way, all VRR technologies are supported.<\/p>\n
The Toshiba Z870 model operates on the VIDAA U7 intelligent platform.\u00a0Of course, this is not as widespread a system as Android TV, but it also has a sufficient number of applications in its arsenal, and the user interface is just as fast and responsive.\u00a0This is one of the smart options for smart TV manufacturers as it prioritizes performance, usability and cost.<\/p>\n
VIDAA OS has a customizable navigation bar at the top of the screen.\u00a0It can be called up without first exiting your current settings, and it seamlessly switches between apps that remain active in the background.\u00a0The panel houses Smart TV applications and functions.\u00a0You can add and rearrange apps and features as you see fit.<\/p>\n
Voice control of the TV is carried out both through the remote control microphone and hands-free through the microphone built into the TV body.\u00a0There is an option to broadcast the screen of a mobile device to a TV screen.\u00a0The built-in media player plays almost any format of audio, video and photo content.<\/p>\n

<\/p>\n
A distinctive feature of the Toshiba Z870M TV is its 5-channel 2.1.2 audio system.\u00a0The unique Tru Bass Booster and REGZA Bass Woofer Pro technologies are responsible for adequate bass sound.\u00a0This series also includes upward-firing speakers, which make Doby Atmos support a real feature.\u00a0IMAX Enhanced also supports DTS, giving audio a unique sense of spatial presence.\u00a0The total acoustic power of the TV is 60 W.<\/p>\n
In the list of TV ports, we first list the HDMI ports.\u00a0There are four of them: 2 versions 2.1 (up to 144 Hz, one with\u00a0eARC\u00a0) and 2 versions 2.0 (up to 60 Hz).\u00a0Next are the USB ports: version 3.0 on the side and version 2.0 on the back.\u00a0There is a LAN port and a digital optical audio output, there is an analog AV input via an adapter and two antenna jacks.\u00a0Wireless communication is implemented via dual-band WiFi and Bluetooth 5.0.<\/p>\n
Toshiba Z870M has very few competitors in this price range. Its brightness, contrast, color rendition and image clarity are beyond doubt.\u00a0Add to this all the gaming and smart features and an attractive price.\u00a0This is definitely a recipe for success.<\/p>\n
There are also several weak points.\u00a0The bloom is not completely absent and can be seen in some scenes.\u00a0Viewing angles are not very good.\u00a0The Toshiba Z870M still only offers 2 HDMI 2.1 ports.\u00a0But if you’re looking for great performance at a very affordable price, then this option should definitely be at the top of your consideration list.<\/p>\n","protected":false},"excerpt":{"rendered":"
