The Samsung QN85B vs QN85A differences fall into the following categories: the first being upgrades (such as the 14-bit processing on the QN85B vs 12-bit on the QN85A; the QN85B's ability to diffuse light from the Mini LEDs in a way that matches shapes and surfaces being shown on the screen; the addition of a Dolby Atmos decoder). The second category is alterations (such as the use of VA-type of panels in the QN85B series instead of IPS-type that most of the QN85A models have). The third category is downgrades because the QN85B lacks the anti-reflective layer of its predecessor: the QN85A.
| Samsung QN85B | Samsung QN85A | |
|---|---|---|
| Model Year | 2022 | 2021 |
| Size class | 55"; 65"; 75"; 85" | |
| The Samsung QN85B retains all the size variants that the QN85A can be found in. | ||
| Resolution | 4K (3840x2160) | |
| Display Type | LCD | |
| Even though the Samsung QN85B and QN85A are both utilizing LCD (Liquid Crystal Display) panel technology, there is a variation in the exact type of LCD panel they use (even within the same series as is the case with the QN85A). | ||
| Panel Type | VA | IPS* |
| *Except for the 85-inch class QN85A model which has a VA (Vertical Alignment) type of panel while the remaining three models in the QN85A range have IPS-type (or ADS to be precise) panels. In comparison, the Samsung QN85B uses VA (Vertical Alignment) type of panels across all size variants. The two panel technologies differ primarily in the viewing angles, native contrast ratio, and screen uniformity. | ||
| Viewing Angle | Ultra Viewing Angle | Wide Viewing Angle* |
| *Except for the 85-inch QN85A model which uses the Ultra Viewing Angle layer (that all QN85B models also have) in order to improve the otherwise narrow viewing angles VA panels typically have. The rest of the QN85A series, though, don't require such a layer because their IPS-type of panels can natively provide wide viewing angles, and even outperform the Ultra Viewing Angle layer in some areas such as retaining color saturation at more extreme angles as well being less prone to off-axis gamma shift (so that the image doesn't look dark when viewed from the side). | ||
| Backlight Type | Quantum Mini LED (Full-array) | |
| The Samsung QN85B and QN85A use thousands of Mini LEDs that are approximately 40 times smaller than a regular LED module. Also contributing to their compactness is the fact that the Mini LEDs are designed to disperse the emitted light via a layer rather than an additional lens (thich would take more space). There is a difference, however, in how the QN85B and QN85A diffuse light. | ||
| Light Diffusion | Shape Adaptive (Asymmetrical) | Symmetrical |
| The Mini LEDs on the Samsung QN85A diffuse light evenly (in all directions) due to the symmetrical spatial filter. The Samsung QN85B, on the other hand, features Shape Adaptive Light Control that utilizes asymmetrical spatial filter (and optical diffusion) in order to better adapt the shape of the emitted light to the shapes and surfaces that are being displayed (and their luminance values as required by the source signal). The Shape Adaptive Light Control on the Samsung QN85B is thus able to reduce the amount of artifacts created in the process of local dimming and boosting of the backlight. | ||
| Local Dimming | Yes (Quantum Matrix Technology) | |
| Although there is no difference in the number of local dimming zones on the QN85B vs QN85A, the level of precision is not the same due to the presence of the Shape Adaptive Light Control on the QN85B, as previously mentioned. As a result, the newer model is able to reduce halos and blooming to a greater extend in comparison to the QN85A. | ||
| Luminance Scale | 16,384 levels (14-bit) | 4,096 levels (12-bit) |
| The 14-bit processing provides Samsung QN85B with 4 times as many luminance steps as the QN85A which has 12-bit processing capabilities. The increased precision in luminance expression on the QN85B translates to more details being visible in some particularly challenging scenes with deep shadows and bright highlights which is why Samsung calls this technology 14-bit HDR Mapping. | ||
| Dynamic Range | Quantum HDR 24x | |
| The Quantum 24x index corresponds to approximately 1,500 cd/m2 peak brightness that can be attained by both the Samsung QN85B and QN85A in small highlights with HDR content. Both TVs are thus able to render HDR content mastered to 1,000 nits without significantly deviating from the creative vision of the content creators by keeping tone-mapping to a minimum (especially if you use the Filmmaker Mode). | ||
| Color | 10-bit depth; 100% Color Volume | |
| The 100% Color Volume, as Samsung calls it, means that the QN85B and QN85A are able to cover the DCI-P3 color space fully at different luminance levels, and show fully saturated colors even when displaying bright highlights. This is achieved through the use of Quantum Dots, which fine-tune the spectrum of the backlight in order to achieve narrow bands of the three primary colors. The billion color shades that the Samsung QN85B and QN85A are capable of, however, is achieved through the use of 10-bit panels. | ||
| Processor (& features) | Neo Quantum Processor 4K | |
| The QN85B and QN85A have identical processor, meaning that they also share some (but not all) of the image processing features. For example, both TVs have AI Upscaling but their contrast enhancing technology is different. | ||
| Real Depth Enhancer | Contrast Enhancer | |
| The Samsung QN85B enhances contrast by first determining which object is in the foreground, and applying most of the enhancements there. By having a highly-contrasting foreground object, the overall sense of dimensionality can also be increased on the QN85B. | ||
| Refresh Rate | 120Hz | |
| Unlike some of the higher-end Samsung Neo QLED TV models for 2022, the QN85B doesn't support 144Hz refresh rate, meaning it's identical to the QN85A. | ||
| Input Lag | ~10ms (@60Hz); ~6ms (@120Hz) | |
| The two Samsung TVs have very low input lag which makes them equally suitable for gaming. | ||
| HDMI 2.1 ports | 4 (out of 4) | 1 (out of 4) |
| The Samsung QN85B can accept 4K 120Hz signal on all of its HDMI inputs whereas the QN85A can do that only on one of them. Both TVs support HDMI 2.1 features such as eARC, ALLM, and VRR (FreeSync Premium Pro). | ||
| Anti-Reflection | No | Yes |
| The Samsung QN85B lacks the anti-reflective coating of its predecessor: the QN85A, so the newer model is less suitable for bright environments.. | ||
| Audio | 2.2.2-ch | |
| The speaker configuration is identical between the QN85B and QN85A since they both have 2.2.2-channel speakers with a total audio power output of 60 Watts. Furthermore, both of them have dedicated up-firing speakers so that they are able to provide three-dimensional sound matching the on-screen action thanks to the Object Tracking Sound technology. | ||
| Dolby Atmos built-in | No | |
| The Samsung QN85B has a Dolby Atmos decoder which allows you to directly listen to audio tracks in this format via the TV speakers. | ||
| EyeComfort Mode | Yes | No |
| Even though both TVs have built-in light sensor, and are able to adjust the screen brightness depending on the ambient light, the Samsung QN85B has the capability to adjust the color temperature in accordance to the on the time of day. The warmer color temperature in particular provides for more comfortable nighttime TV watching. | ||
