Samsung QN80F 100" vs TCL RM7L

When it comes to HDR in Filmmaker mode, the QN80F can make a great first impression on you. Our lab tests showed that under the best conditions, the TV can achieve brightness exceeding 1200–1300 nits. These are truly remarkable results, which make HDR effects in many films look incredible. The TV is simply bright enough that it doesn’t need to artificially adapt the picture – bright parts of scenes have the right "power" and actually look like a light source. Of course, the lab is one thing, and everyday viewing is another. In practice, during movie scenes, brightness usually oscillates between 700–1100 nits. These are still great values that, in most cases, give a strong sense of realism and make the lights on screen really capable of dazzling you. The problem arises in exceptionally challenging sequences, where, like almost every mini-LED, it reveals its limitations. A good example is Sicario 2: scenes with helicopters in the night sky look much weaker, and the lights lose intensity, dropping to around 370 nits, making it hard to speak of serious admiration. This leads us to the topic of colors. Although we are dealing with a QLED, the coverage of the DCI-P3 color palette is about 90%. This is fairly average for a quantum dot TV. In practice, this means that some colors may appear less saturated than we would expect, especially in demanding HDR productions.

The TCL RM7L is a bright TV. In our measurements its peak brightness hovered around 1600 nits. That's clearly less than the C7L, which can approach 2600 nits, but in real movie scenes the difference between the two models isn't that big. In less demanding shots with many bright elements on screen, the RM7L can hold around 1000 nits, and sometimes a bit more, approaching 1500 nits. It performs worse in dark scenes with small highlights; then their brightness can fall to around 500 nits. However, this behavior is not accidental. The TV intentionally dims small elements to better control the backlight and maintain higher contrast. This comes at the cost of their intensity, but it's typical behavior for local-dimming TVs in a similar price bracket.

Color gamut coverage

In HDR it's not only brightness that matters, but also color. And here the RM7L has a lot to show. Colors are strongly saturated, and a wide color gamut is one of its bigger strengths. In measurements it reached about 96% of DCI-P3 and around 83% of BT.2020. It's worth remembering, though, that on a TV with this kind of backlight the result can vary depending on the scene. On test patterns colors look best, while in movies their saturation can be a bit lower than on SQD Mini LED or QD-OLED TVs. The backlight construction itself is also interesting. The RM7L doesn't use the classic red, green and blue diode set. TCL used two green diodes and one blue, and obtains the red color using a PFS phosphor. You can see this in spectrometer measurements, but it doesn't have a major impact on the picture. Colors are still produced correctly.

Samsung QN80F performs best in Filmmaker mode, which is designed to faithfully convey the creators' intentions. And indeed – it is a mode in which the TV showcases its potential. But let’s not deceive ourselves, it is far from perfect. In SDR content, a problem with white balance became apparent. Slight deficiencies in green and a clear excess of red caused the screen to take on a pinkish hue. You don’t even need measuring tools to notice this – in everyday viewing, the slightly shifted color palette could be quite noticeable, and in color checker tests, colors were even "jumping" out of their reference fields. With HDR content, the situation was a bit better, as the white balance was closer to ideal, but another problem emerged – brightness management. The EOTF curve often caused the image to become too bright, which spoiled the perception of contrast, and in dynamic scenes led to a slight "flickering" in the reception. We actually already mentioned this in the sections about black levels and HDR. The good news, however, is that Samsung provides a lot of tools for improvement. The QN80F allows for really detailed calibration, including a 20-point white balance. And since the manufacturer left us so many options, we decided to see how the TV would perform after solid corrections.

We checked the factory colors in Filmmaker Mode, the best picture setting available to the user. TCL has been using it in its TVs for two years, and its purpose is to present the image as faithfully as possible in line with the creators' intent. On the RM7L this was indeed the best-calibrated mode, although it wasn't without flaws. The biggest issue was the white balance. An excess of red and blue caused the picture to take on slightly pinkish tones. This was visible in both SDR and HDR. Additionally, the luminance response was slightly boosted, which made the image appear a bit brighter but also less contrasty than it should have been.

After calibrating the QN80F, it immediately showed that it is capable of much more. The pink tint that could previously spoil the reception has disappeared, and the white balance finally looks as it should – natural and without excessive deviations. The colors have gained depth, and the image has become more saturated and consistent, making movies simply more enjoyable to watch. It's a bit like removing a light haze from the screen – suddenly everything seems sharper and clearer. Brightness management has also improved. The television no longer gets lost so easily in dynamic changes, and the EOTF graph shows that the curve tracking is much more stable. Of course, there are no miracles – the limited number of zones still means that small, bright elements can be slightly brightened, but that is due to the construction itself, not the settings. After this adjustment, the QN80F feels like a more mature piece of equipment, and watching movies finally provides the satisfaction one expects from a television even in the higher class.

Thanks to a fairly extensive calibration menu, we were able to correct the vast majority of the errors described earlier. The biggest change was to the white balance. After calibration it looks very good, so the image lost its pinkish cast and became much more neutral. The luminance response itself also improved. Both the SDR gamma and the HDR EOTF curve are now much closer to the reference values. The image is no longer unnecessarily brightened, and darker areas look more natural and have more depth. Better luminance accuracy also affected the colors, which after calibration are noticeably more accurate. Not everything could be set perfectly, though. In HDR material the RM7L still interprets part of the signal its own way and does not always follow the reference curve exactly. This is most apparent in some darker scenes, where the TV can either slightly lift the shadows or darken them completely. That was the source of the earlier impression of a slightly brightened, less contrasty image. Even so, the calibration delivers a very good result here. It removes the most visible errors and, above all, makes the image much closer to how it should look.

With lower quality materials, such as YouTube videos or older television recordings, the QN80F can showcase its stronger and weaker points. If strange color transitions or artifacts start appearing on the screen, it's worth using the noise reduction function. The best setting is at the "medium" level – it smooths out the problematic segments without blurring the entire image. However, one compromise must be kept in mind: this function always removes film grain. If someone enjoys its presence in older productions, it's better to leave the reduction turned off because, regardless of the setting, the grain simply disappears.

Resolution scaling, or upscaling, is another strong point of Samsung. The QN80F may not be the best TV on the market, but it performs very well in its price range, which is very important for such a large size as a 100-inch screen. Even low-quality materials can gain a second life – the image becomes sharper, more readable, and overall much more pleasant to view. A weak point remains overscan, or slight trimming of edges in very low resolutions (e.g., 576p), which has been a longstanding issue for Samsung. Fortunately, in everyday viewing of HD and 4K content, this practically doesn’t matter anymore.

Upscaling and digital image processing are not the RM7L's strong suit. TCL used a MediaTek Pentonic 700 SoC here, designated MT5896, which isn't among the best processors at handling lower-quality content. The biggest problems show up with heavily compressed material from YouTube or regular broadcast TV. The processor can't effectively hide posterization and the characteristic color banding. The feature meant to smooth them does little here, and it often interferes too much with the picture, smoothing faces or fine textures, for example. For that reason, it's best to simply leave it off.

Straightforward upscaling to 4K looks better. Lower-quality sources remain reasonably sharp and retain enough detail. It's not on par with the best processors on the market, but for everyday viewing the result is entirely acceptable.

The QN80F features a 144 Hz panel, and this is evident in practice – with full refresh, the image is exceptionally smooth, and motion blur remains at an acceptable, barely noticeable level. However, this mode is mainly aimed at PC gamers. The most important reference point in everyday use remains a 120 Hz refresh rate, and here a certain discrepancy arises. During the UFO test, we noticed the blurring of contours of quickly moving objects – it looked as if the television had the BFI (Black Frame Insertion) function permanently enabled, which in practice led to an unpleasant double edge effect. We do not yet know if this is a software issue or a characteristic of this model, but in its current form, it is difficult to praise such behavior.

The RM7L uses a 144 Hz VA panel, so right out of the box it's a TV well suited for sports, gaming, and other fast-moving content. The high refresh rate also gives the motion interpolation engine more room to work, allowing it to generate extra frames. On the RM7L it works well, and with the right settings it can noticeably improve motion smoothness without causing an excessive soap opera effect.

Samsung QN80F gives the impression of a television designed with gamers in mind. On the list of advantages, we have a 144 Hz panel, four full HDMI 2.1 ports, complete support for VRR and ALLM, and one of the best-designed game bars on the market. In addition, there's the Game Motion Plus motion smoother, which works in games without actually increasing input lag, making the QN80F an absolute standout in this category. In practice, this means that you can enjoy a smoother picture without losing responsiveness, which is a dream for many console gamers!

As usual with Samsung, there’s a lack of Dolby Vision in games, and that's not surprising anymore. However, what surprised us much more is that in the 2025 models… the HGIG feature has disappeared. It was the feature that allowed consoles like PlayStation 5 or Xbox Series X to perfectly match HDR tone mapping to the capabilities of the television. In the current firmware of the QN80F, this option is simply not available—it seems more like a mistake than a conscious decision by the manufacturer, but on the day of testing, we have to acknowledge that HGIG is not available. Because of this one missing feature, the QN80F goes from being an almost perfect television for gamers to an "almost" perfect device. It's quite a shame because aside from this, Samsung has created a model that really sets the bar high in the gaming hardware segment.

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

You can say almost nothing but good things about the RM7L when it comes to gamer features. The TV supports ALLM, VRR, Dolby Vision Gaming and works correctly with HGiG, so it’s hard to point out any major omissions in that area. In practice this means automatic switching to low-latency mode, a smoother picture with variable frame rates, and accurate brightness reproduction in HDR games. There’s also a handy Game Bar. From it you can quickly check the frame rate, VRR status, signal format, and aspect ratio, and change key settings without leaving the game. TCL also added a few extra options, like a crosshair and brightening of dark parts of the image, which can be useful in some titles. The biggest downside comes from the use of the Pentonic 700 processor. Only two of the four HDMI ports support the full HDMI 2.1 standard. With a single console this won’t matter much, but when connecting two consoles and a PC you may run out of space. Especially since one of those ports may also be needed for eARC and a soundbar.
