Samsung QN85F vs TCL P7L / P79L

Although the more than double number of dimming zones compared to its predecessor has not translated into a spectacular jump in black levels and contrast, we definitely felt it in the HDR effect itself. The QN85F is up to 50% brighter than last year's model, making a huge impression in dynamic scenes. The peak brightness can reach nearly 1700–1800 nits, which is truly impressive in this Mini-LED class. The best part is that almost regardless of the scene being viewed, the HDR effect remains strong and vibrant. In four out of five test scenes, the brightness was around 1000 nits, a level that in most cases allows viewers to feel the true magic of this format. Of course, in scene number 4 from the movie Sicario 2, the limitations of Mini-LED technology become apparent – the brightness of the helicopter's spotlight drops to around 500 nits. It's not an outstanding result, but it's still much more acceptable than in last year's model. Samsung deserves applause, as the improvement in brightness in the QN85F is substantial compared to its predecessor. However, it's a pity about a certain trend seen in this year’s televisions – the manufacturer has worsened the color gamut coverage. Although the QN85F has a QLED panel, its result of around 90% DCI-P3 is average, and in the most demanding films, it can lead to less vibrant colors than in the predecessor. Despite this shortcoming, the overall HDR effect is at an excellent level and really makes a big impression in this class of devices.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV doesn't have a large luminance headroom, so strong highlights, sunlight, or small light sources can't clearly "pop" out of the image. As a result, even well-produced HDR material looks fairly restrained and in terms of dynamic range is closer to good SDR than to what brighter models show. That doesn't mean the P7L can't handle HDR at all — the issue is mainly a lack of sufficient backlight power.

Looking at color, the situation is a bit better. The TV covers about 91% of the DCI-P3 gamut and about 68% of the wider BT.2020 color space, so for its price class the color range is quite decent. TCL markets this model as QLED, though the nature of the solution used is closer to a PFS phosphor-based backlight than a classic quantum-dot layer. What matters most to viewers, however, is the result: more saturated colors are available.

The Samsung QN85F offers several preset picture modes, but out of the box, the television starts in "Eco" mode. We could actually end the discussion here, because for such a model, using this setting makes no sense – the picture is washed out, unpleasant, and far from what we expect from a television of this class. Therefore, we conducted our tests in the best available mode, which is the Filmmaker mode. Its purpose is to faithfully reproduce what the directors saw while filming, and indeed, this setting performs best among all the factory options. However, this does not mean it is free of flaws.

Both in SDR and HDR, the QN85F strongly highlighted warm colors. This stemmed from a lack of white balance, with a noticeable absence of blue. Additionally, the picture sometimes appeared overexposed – both the gamma brightness characteristic and the EOTF curve indicated that the television has a tendency to blow out scenes. In SDR, the color reproduction errors (Delta E at levels of 4–5) were still acceptable, but in HDR, the inaccuracies became really significant and clearly deviated from what the creators intended to show us. Fortunately, Samsung provides a wide range of calibration tools in its televisions, so – as always – we proceeded with professional calibration to see how much could be improved.

In Film mode the TCL P7L performs fairly well without major adjustments, especially with typical SDR material. The white balance is relatively even, although as brightness increases there is a slight rise in red and blue and a bit of a shortage of green. This does not produce a strongly noticeable tint and most colors remain close to their reference points. The ColorChecker confirms this, with a large portion of errors falling below a level that would notably bother viewers during normal watching. We have more concerns about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference, so some shadow detail can be a little too dimmed. The curve then settles and for much of the range it is close to the intended target. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety. In HDR the factory setting is less precise. As brightness increases an excess of blue becomes more pronounced, making the image look cooler than it should. The number of larger color deviations also grows, particularly in brighter hues. The EOTF curve itself is handled fairly conservatively, with the TV showing the image darker than the reference over a large portion of the range. For a budget model, however, the factory Film mode settings are not bad.

After calibrating the movie mode, we managed to tame the colors in both modes to nearly perfection – most of them did not exceed an error value of 3, which is the limit of visibility to the human eye. The image became more natural, fuller, and at the same time devoid of the blooming that was noticeable right after taking the TV out of the box. This shows how much potential lies in the QN85F and how well it responds to precise settings. However, this does not change the fact that certain technological barriers cannot be overcome. Despite the significant benefits of calibration, limitations of the panel itself still remain. Although the number of dimming zones has doubled compared to its predecessor, the algorithms controlling the backlighting can manipulate brightness in their own way. Sometimes this leads to slight color distortions or subtly visible halo effects around bright objects. Nonetheless, the reception after calibration is really pleasant and shows how good a screen the QN85F can be if we just take a moment for the right settings.

After calibration, the TCL P7L can deliver a really pleasant picture, especially with classic SDR material. We managed to very effectively even out the white balance, and the gamma curve now tracks close to the target value of 2.4. You can also see this in the color measurements, as most errors dropped noticeably, and in everyday viewing it's hard to find any strongly visible inaccuracies. Movies, series, YouTube, or regular TV therefore look more natural, without unnecessary warming or a cool cast. For a model in this price range, the result in SDR is really very good.

With HDR the situation gets more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and can't maintain appropriate luminance for more saturated colors, so some errors remain even after careful tuning. In other words, settings can improve how the TV interprets the signal, but they can't overcome its physical capabilities. That's why calibration makes the most sense for this model primarily with SDR.

Although the native tonal transitions on the QN85F perform excellently with 4K materials, we don't always deal with content in the highest resolution. That's when it becomes crucial how the television handles upscaling and digital image processing. This process is managed by Samsung's proprietary processor – AI NQ4 Gen2. In practice, it works very efficiently. If visible color banding or other undesirable phenomena appear on the screen, for example in materials from YouTube, they can be easily smoothed out using the "noise reduction" function. Set to medium, it improves tonal transitions while not excessively blurring desired details. However, it's important to remember that – as with most Samsung televisions – this feature significantly affects the film grain. Therefore, during movie screenings, it's advisable to use it cautiously to maintain the natural character of the image.

The upscaling itself looks very good. Test materials in lower resolutions were displayed sharply and clearly, with a lot of detail. The only drawback remains the issue of overscan, which is cutting off the edges of the screen. In most situations, this is not noticeable, but with very old materials below HD quality, there may be instances where part of the image on the left side is slightly cropped.

In this regard the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The tonal transition smoothing feature, which in many budget models does little or almost nothing, actually manages to improve the picture here. It doesn't remove all banding completely, but it can noticeably reduce posterization and make trickier gradients look more natural. At this price point that's a genuinely pleasant surprise.

Upscaling itself also performs well. Lower-resolution material is scaled correctly, without excessive sharpening or adding artificial outlines around objects. Of course the P7L won't turn a very poor source into 4K-quality footage, but for regular TV the result is simply solid. For a model in this class there is little to criticize.

Motion blur and fluidity of motion in the QN85F is a topic worth discussing in more detail, as the television is equipped not with a standard 120 Hz panel, but with a 144 Hz panel. The additional hertz will primarily be appreciated by PC gamers, but the mere presence of such an option can be seen as a nice addition and a sign of the times – it’s hard to complain about the trend towards faster panels, since in practice, each of us would like the image to be as fluid as possible. However, the most important thing is how the television handles typical 120 Hz refresh rates – in the case of consoles, sports, or films recorded at 24 or 30 frames per second. And here, the QN85F performs really well. In movies, you can easily adjust the character of the image thanks to the “picture clarity” function, where we find two adjustable sliders. Key for viewing sessions is the one responsible for reducing motion blur. Lower values give the image a more cinematic character with preserved “frame rate,” while higher values lead to a strong smoothing that resembles television theater.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be treated in everyday use. For movies the TV mainly offers frame interpolation, so it can smooth motion and reduce the typical judder, but it does not deliver the smoothness of true 120 Hz panels.

The Samsung QN85F makes a great impression in terms of features for gamers. It has four HDMI 2.1 ports, so we can easily connect several devices at once. There is also variable refresh rate (VRR) to prevent screen tearing, as well as automatic game mode (ALLM), which allows the TV to switch to the appropriate settings automatically when we start the console. Additionally, it supports refresh rates of up to 144 Hz – something that PC gamers will particularly appreciate, but the mere fact that such an option is available shows that Samsung is fully supporting gamers. The Game Bar panel deserves praise as well. It's a quick glance at key parameters – from frame rate to refresh mode to shortcuts for picture settings. Instead of sifting through the entire menu, everything is at our fingertips, which turns out to be really convenient in practice. However, the most interesting addition is the Game Motion Plus feature. It's nothing more than motion smoothing, transferred into the gaming world. When enabled, the picture becomes smoother, sometimes it even looks as though we're getting several more frames, and importantly, the response delay does not increase enough to interfere with gameplay. This solution truly sets Samsung's 120Hz TVs apart from the competition.

[UPDATE] We have updated our tests of Samsung TVs for the 2025 model year due to the release of software version 1131, which restored the crucial feature for gamers, HGiG.

The only serious downside remains the lack of proper HGiG support. This is a standard responsible for correct tone mapping in HDR games, ensuring that brightness and contrast are displayed as intended by the creators. Without HGiG, we have to adjust the brightness manually, which doesn’t always yield ideal results. The feature was available in previous models, but it disappeared from the QN85F after one of the updates. We hope that Samsung will quickly fix this issue, and we will keep checking to see if it has been resolved.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL adds its Game Bar, which lets you quickly view key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn't work here as it should, but at this price point it's hard to complain much about the feature set. The most interesting thing starts when you give up on 4K. At that resolution the TV runs at a maximum of 60 Hz, but at 1440p and 1080p it can already display at 120 Hz. And that's not just a spec-sheet curiosity. In fast-paced games that support that frame rate you can really notice the difference in smoothness, so if you care more about smoother motion than maximum image sharpness, that mode can make a lot of sense. Of course that doesn't make the P7L a true 120 Hz TV. Even so, it's precisely those extra modes that make the P7L perform really well for gaming.
