QLEDs and OLEDs are famous for high-quality, crisp pictures. No wonder they have been the main focus of renowned electronics manufacturers for years. Samsung and Sony have been launching high-performing LEDs, OLEDs, and QLEDs, but Samsung’s QN90B and Sony’s A90J stole all the spotlight from others. Although they were released a couple of years ago, many people still indulge in the “Samsung QN90B vs Sony A90J” argument.
OLED screens are known for brightness, but modern QLEDs aren’t less than them. The Samsung QN90B QLED combines Mini LED and Quantum Dot technologies to offer more or less the same contrast and HDR picture quality. It also has a mind-blowing audio output and a local dimming feature.
Sony A90J, on the other hand, is an efficient 4K TV that delivers exceptional picture quality from its self-emitting pixels. Its display creates magical blacks and an ideal contrast ratio no matter what you watch. It supports HDR and Dolby Vision for smooth picture motion, making it suitable for gaming. So, what are the most noticeable differences between the two? Let’s find the answers in our Samsung QN90B QLED vs Sony A90J comparison.

Samsung QN90B vs Sony A90J: What’s the Difference?
The Samsung QN90B and Sony A90J have different display types, yet you’ll find them similar in many aspects. Both are one of the hottest LED choices with different standing points, making it pretty hard to choose one.
If you’re on a similar bandwagon, here are some factors you must consider when purchasing a Samsung QN90B or Sony A90J.
Starting with the design, you won’t be disappointed with the design of both Samsung and Sony products. Both have sleek bodies with smooth edges and bezels. Since they were released one after the other, you’ll find many similarities in their stands and accents.
The Samsung QN90B has a slim stand and bezels, taking up less space in total. The TV’s back has a brushed aluminum look since it’s made of high-quality plastic. Its rear area also has multiple channels to manage cables and horizontal etched lines.
This QLED also has ports for OneConnect Box that you can easily control when the TV is on a stand. However, accessing the inputs is difficult when the TV is mounted on the wall.
If you’ve previously used Sony OLEDs, you’ll find no noticeable difference in the A90J’s design. But the stand seems more sturdy and adjustable. You can set it in two ways: from the feet flat or slightly raised to have space for audio output. On the 83-inch A90J, you can also make the TV’s feet face inward to achieve a smaller footprint.
This OLED has metal accents, which give it a sleek and fancy appearance. The cable management on the back is also pretty easy, consisting of cable portions and a cable tie. The rear area also consists of plastic ridges.
Like the Samsung QN90B, the Sony A90J doesn’t have side-facing inputs, so you may find it hard to access them when the TV is wall mounted. Overall, both LEDs are thin, sturdy, and gorgeous-looking.
Samsung QN90B’s display consists of a Quantum Dots layer, giving it a high-end modern finish. This technology works on many tiny nanocrystals, which spark particular colors when the current passes through the TV. Samsung has also enhanced the contrast, brightness, and color combination in this QLED.
The display supports motion in a diverse range with its 120HZ refresh rate. The TV is compatible with various content in HDR10 and HDR10+ except for Dolby Vision HDR. That could be a bummer for some people. However, it won’t make much of a difference altogether.
Sony A90J’s display will delight you as well, especially its brightness in various modes, whether SDR or HDR. Compared to QLED, OLED TVs work on the electroluminescent film layer made of some sort of organic element. It radiates light when an electric current passes through the TV.
Different tests found Sony A90J one of the brightest OLEDs, but it’s no match for Samsung QN90A or QN90B QLEDs. Yet, you’ll love the overall ideal brightness and highlight combination in different scenes. In the SDR mode, the TV may not be consistent and show varying luminance levels. The biggest edge A90J has over its competitor is Dolby Vision HDR compatibility.
Overall, the Samsung QN90B has a slightly upper edge over its counterpart regarding display and brightness. But Sony A90J has Dolby Vision HDR, so it’s your call!
Another difference in our Samsung QN90B vs Sony A90J review is in the picture quality. The QN90B is integrated with Neo Quantum Processor 4K, which ensures crisp and fine pictures in different lighting.
This QLED has an amazing color contrast that offers an ideal black level in dark rooms. It also has a wide viewing angle layer, so you may experience a low native contrast. You can increase the contrast ratio of the TV by putting it on a high local dimming setting, but you can’t disable it from the picture settings menu.
The Sony A90J’s effective OLED panel delivers a near-infinite contrast ratio that produces superior blacks. The picture will appear deep, rich in colors, and slightly inky in dark surroundings, so you’ll have the best movie nights.
The QN90B QLED is ideal for brighter, while the A90J OLED is perfect for darker rooms.
The Samsung QN90B supports variable refresh rates in all three formats, including 1440, 1080, and 4K. This way, this QLED works amazingly with different types of content while delivering fine, crisp picture quality.
The QN90B also has a low-frame rate compensation (LFC) feature that enhances the frames in games with low refresh rates. It also offers a maximum refresh rate of 144Hz, but only in the 43-inch and 50-inch variants.
Meanwhile, Sony A90J OLED has a 120Hz refresh rate with a variable rate reaching 144Hz. The TV is also compatible with G-SYNC, but the screen may start flickering with the NVIDIA RTX 3060 graphics card in a few games. But with the recent firmware update, you won’t face any issues with 1080p signals at 120 fps.
Regarding the refresh rate, we can call it a tie between Samsung QN90B vs Sony A90J. Both devices are ideal for gaming.
A TV’s input lag can make or break your gaming experience. A higher input lag rate translates to more delay between your controller and screen. It also indicates that the TV will respond slower.
The Samsung QN90B QLED has very low input lag, especially in “Game Mode.” It can be even lower in the “Game Motion Plus,” allowing you to enjoy your favorite regardless of their required frame rates. At the maximum setting, you can have 24.4ms of input lag in the Game Motion Plus mode.
On the other hand, Sony A90J also offers a low input lag rate, but it’s relatively higher than other OLEDs on the market. Without the “Game” Mode, this rate can be even higher. So, always games in “Graphics” or “Game” Picture Modes for low latency.
The initial input lag for 4K at 120Hz was 14.7ms. With the current firmware update, it increased by 3ms.
The Samsung QN90B QLED operates on Tizen, which ensures a fast and simple interface. In the previous QLED models, you may have seen that the interface filled just the bar. Things are a bit different in the QN90B. The Tizen interface now covers the entire QLED screen, allowing you to easily navigate and find the content you want to watch.
While the TV has all the primary smart apps installed, you can also download your favorite ones from the Samsung App Store. You can also use the video call feature on this TV by installing a webcam, which is compatible with Google Duo.
Meanwhile, the Sony A90J operates on Google TV, similar to an improved version of Android TV. The navigation is pretty smooth and simple without any issues. You can also access your recently-used apps from a single hub where all your favorite content is organized. You can download different apps from the App Store and access them easily from the smart hub. This OLED supports and runs all the apps smoothly.
