OLEDs have a worthy rival? Samsung QN91B surprises with black, contrast and gaming features [TEST]

- Advertisement -

Samsung QN91B is the successor to a successful model QN91A. As in the case of its predecessor, also here we are dealing with MiniLED backlight. This is great news, because the MiniLED technology minimizes (but does not eliminate) the biggest disadvantage of LCD screens, which is the average contrast and blackness – especially in combination with OLEDs.

Samsung has got us used to the fact that in its flagship QLED TV sets it focuses on minimalism and elegance. It is no different in the case of the tested model. The almost frameless screen and the extremely slim body of the device (only 26 mm deep) attract attention here. A solid and massive stand that stabilizes the device also looks good.

Unlike the Q95 series, Q91 models do not use the additional One Connect module. All the necessary connectors are located on the rear panel of the device.

Speaking of ports, we can find quite a lot of them here. We have at our disposal 4 HDMI 2.1 ports (including one with eARC), 2 USB-A ports, an Ethernet connector, a TOSLINK port, and an antenna output.

The One Remote remote control remained unchanged. It has a joystick, some of the most important function buttons and shortcuts to the Netflix, Disney + and Prime Video applications. The remote control is equipped with a battery that we will charge via USB-C port or using for this light sunny – a small solar panel is placed on the back of the device.


Samsung Neo QLED QN91B – SCREEN

Samsung QN91B has a screen LCD QLED 4K With MiniLED backlightmatrix VA and 120 Hz refresh rate. I have written about QLED technology and quantum dots many times in Gazeta.pl. In short, it represents the next stage of development LCD technology. Quantum dots are crystals with a diameter of several tens of thousands of times smaller than the diameter of a human hair, which have a special property – they can emit light with an extremely pure and natural color.

Last year, Samsung added another novelty to this, i.e. the mentioned one MiniLED technology. It is a kind of screen backlight layer which consists of thousands of tiny LEDs, which form the so-called blanking zones. In the case of the 55-inch QN91B model, there are as many as 720 such zones.

Thanks local blanking function the TV can precisely control the matrix backlight. Example? A cinematic scene in which we see a lot of black and only one bright object. In a situation where the TV does not have a local dim function or there are few zones, instead of black around a bright object, we will see gray.

MiniLED solves this problem, and more blanking zones translate to better contrast and deeper black. And these are not empty promises. Every day I use an OLED screen that offers infinite contrast and black. After switching to a Samsung TV with MiniLED backlight, it was probably the first time that I had no subjective impression that I was losing something on this replacement.


It would be an abuse to say that MiniLED removes all differences between LCD screens and organic matrices. However, I can write that in terms of contrast and blackness, QLEDs have never been so close to OLEDs. If you do not believe my words, I encourage you to read

The QN91B impresses not only with its excellent blackness, contrast and high maximum brightness, but also with excellent viewing angles, which in the case of VA matrix it is not so obvious. This is due to the use of a special coating, which eliminates the problem of color degradation.

There was also support for the standard HDR10 +. Still missing, however handling Dolby Vision. For incomprehensible reasons, Samsung refuses to implement this standard, which is lost, for example, by people watching Netflix content or playing games with Dolby Vision support.


Samsung Neo QLED QN91B – SOUND

The situation is so strange that it came to Samsung TVs this year Dolby Atmos (maybe this is a signal that we will also see Dolby Vision next year?). QN91B supports this technology, both wired and wireless – of course, if we have the appropriate soundbar.

Before we talk about soundbars, however, let’s focus on what the QN91B offers out of the box. We have speakers with total power at our disposal 60W (4.2.2CH). They sound pretty good, but not great. At times the sound is too shallow and not very expressive. It is true that Samsung has put at our disposal the function of an active voice amplifier, but it is doing quite average.


So if you plan to buy this model, I recommend buying additional speakers stereo with the receiver (more expensive option) or soundbar (cheaper option). Personally, I have never been a fan of soundbars, but with the Samsung MiniLED I also had the opportunity to test the Samsung HW-Q800B soundbar and I must admit that I am positively surprised by its power and clarity of sound. And wireless support for cinema technology Dolby Atmos it is an additional advantage in its favor.



The QN91B is great as a universal TVr for watching sports, movies and series, as well as linear television (there is also a solid upscaling and DVB-T2 HEVC tuner). However, if it were to indicate a group of users who should be particularly interested in this device, it would be players. Samsung’s MiniLED is made for gaming.


Let’s start with the obvious. The TV is equipped with 4 HDMI 2.1 ports, and this is the most important parameter that we should pay attention to when looking for a screen for the Xbox Series X or PS5. Without HDMI 2.1. we can forget about playing in 4K resolution and 120 FPS.

Another technology that opens up for us HDMI 2.1 standardthis Variable Refresh Rate. VRR improves the synchronization of the screen refresh rate with the frame rate (FPS), making the image smoother.


Another technology straight from the next generation consoles supported by the Samsung QN91B is Automatic Low Latency Mode (ALLM). It lowers the input lag in the dedicated “Game” mode. In this mode, we can also adjust the motion fluidizer settings (Motion Plus Game).

As for the mentioned andnput lag, in the case of the Xbox Series X and PS5 consoles, in 4K @ 60 FPS mode it is ~ 14 ms, and in 1080p @ 120 FPS mode – only 8 ms. These are really great results.

A complete novelty in Samsung TVs for 2022 is the appearance of the Xbox Game Pass application. All we need to do is hook the controller to the TV and we can play the latest titles from the Xbox library, such as Forza Horizon 5 or Halo Infinite – without the need to buy a console.

Of course, this solution has its drawbacks and limitations. Since the game is streamed from the cloud to the TV screen, we must take into account slight delays and more input lag than when playing on the console. For this reason, I would rather not recommend using this feature in games where low input lag is crucial (eg FIFA or Battlefield). However, the very fact that the game streaming technology has appeared on Samsung TVs is worth noting.


Samsung Neo QLED QN91B – TIZEN

The Tizen system has seen significant changes in the visual aspect this year. Its UI is now even more “tiled”, with the home screen becoming the central element Smart Hubwhich allows us to quickly access the most important shortcuts, settings, image sources and applications.

In the case of apps such as Netflix, Prime Video, HBO Max or Apple TV +, we can even play an episode of our favorite series directly from the Smart Hub screen, without having to go to the main screen of the application.

One of the most interesting features offered by Tizen is Multi View. It allows you to divide the TV screen into two parts. On one of them, we can watch the match broadcast, and on the other, the image sent from the screen of our smartphone – e.g. the latest comments on Twitter.

Tizen also supports the Remote Access function, which allows you to remotely connect the TV to a computer in our home or office and work with Microsoft 365 documents. All you need to do is to equip yourself with a Bluetooth mouse and keyboard.

Samsung Neo QLED QN91B – SUMMARY

Samsung Neo QLED QN91B is undoubtedly the best MiniLED AD 2022 TV. It offers a picture close to the ideal with high contrast and maximum brightness and deep blacks. Although it can act as a universal TV, it will work best as a screen for new generation consoles.

If I were to point out its disadvantages, the only thing that stands out (or rather ears) is the average audio quality from the internal speakers. This problem is solved by the soundbar and Dolby Atmos mode, but unfortunately you have to pay extra for such a convenience.
