Samsung QN80H vs TCL RM7L

The Samsung QN80H is undoubtedly a bright TV. In synthetic tests it exceeds the 1000-nit mark, which on paper promises a solid HDR effect. In practice the screen really shows its teeth, although it can't fully spread its wings (or its backlight, if you will 🤔) in every condition. Bright, wide scenes make the best impression. Well-lit outdoor shots and brightly lit scenes look really good on it. Brightness then stays around 700 nits, which provides a noticeable step up in quality compared with standard SDR. Problems start in dark scenes with small, pinpoint highlights. The QN80H tends to dim these strongly, in order to protect black depth at all costs. On the one hand this gives better contrast, on the other... you lose dynamics and the brilliance of fine HDR detail. So the TV has considerable potential, but the dimming algorithm can be too restrictive.

Colour gamut coverage

When it comes to colours it's good as well. The QN80H uses quantum dot technology, and in our measurements it covered 93% of the DCI-P3 colour space and about 70% of BT.2020. Today those results aren't exactly jaw-dropping, but in real-world use they're more than sufficient to deliver a vivid, natural image for most films and TV series. Colours are suitably saturated, and after proper calibration they don't look artificial or overly aggressive.

TCL RM7L is a bright TV. In our measurements its peak brightness hovered around 1600 nits. That is clearly less than the C7L, which can approach 2600 nits, but in real film scenes the difference between the models is not that large. In less demanding shots with many bright elements, the RM7L can sustain about 1000 nits, and sometimes even a little more, getting close to 1500 nits. It performs worse in dark scenes with small points of light, where their brightness can fall to around 500 nits. This is not random behaviour. The TV intentionally dims fine details to better control the backlight and preserve higher contrast. That comes at the expense of their intensity, but it is typical behaviour for TVs with local dimming in a similar price bracket.

Colour gamut coverage

In HDR not only brightness matters but also colour. And here the RM7L has plenty to show. Colours are highly saturated and a wide colour gamut is one of its major strengths. In our DCI-P3 measurements it reached about 96%, and BT.2020 around 83%. It is worth remembering that on a TV with this kind of backlight the result can vary depending on the scene. On test patterns colours look best, while in films their saturation is sometimes a little lower than on SQD Mini LED or QD-OLED TVs. The construction of the backlight itself is also interesting. The RM7L does not use the classic red, green and blue LED set. TCL used two green LEDs and one blue, with the red produced by a PFS phosphor. This shows up in spectrometer measurements, but it does not have a major impact on the picture. Colours are still rendered correctly.

The factory settings of the QN80H performed really well, especially compared with the majority of TVs we receive for testing. Of course, our measurements were taken in Filmmaker Mode, and that's the mode we recommend turning on immediately after the initial setup. For SDR material, our sample was set up surprisingly well. The white balance was very even, colours looked natural, and errors were so small they were hard to notice without measurement equipment. The only weaker point was the gamma. In the brighter parts of the image the TV brightened them a little too much, which at times made the picture lose some depth. Still, we'd like most TVs to look this good straight out of the box.

It fared a little worse in HDR. The white balance was still set correctly, so the problem was not with the colours but with the way the QN80H managed image brightness. This was immediately visible on the EOTF chart. The TV brightened large parts of scenes too much, causing the brightest elements to clip. Interestingly, very small points were often dimmed too much at the same time. As a result, some fine details simply disappeared. So the factory Filmmaker mode in HDR is not bad, but it is definitely not as well calibrated as in SDR.

We checked the out-of-the-box colours in Filmmaker Mode, the best picture setting available to the user. TCL has been using it in its TVs for two years, and its aim is to reproduce the image as faithfully as possible in line with the creators' intent. On the RM7L it was indeed the most accurately set mode, although it was not without flaws. The biggest problem was the white balance. Too much red and blue made the image shift towards slightly pink tones. This was visible in both SDR and HDR. On top of that the brightness response was slightly boosted, making the picture appear a little brighter but at the same time less contrasty than it should be.

We saw the biggest difference after calibration in HDR Filmmaker mode. SDR was already very good out of the box, so we didn't have much work to do there. In HDR, however, we managed to get to grips with the way the QN80H handled brightness, as it had been over-brightening most scenes. After calibration the picture is calmer, more natural and much closer to how a faithful image should look.

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

Digital image processing in the Samsung QN80H is handled by the second-generation NQ4 AI processor. It's a chip we already know from the manufacturer's earlier models, and it still performs very well, especially with lower-resolution content. The image is effectively upscaled to 4K, but without excessive sharpening and without giving the impression the TV is aggressively trying to improve the source material.

The "Noise Reduction" function also proves useful. It can noticeably reduce posterisation and visible banding in lower-quality material, particularly in low-bitrate streaming. However, it's important to remember that it does not work without side effects. It can remove some film grain and slightly smooth the image. So with a high-quality source we'd leave this function switched off. If, however, someone is more bothered by banding and uneven tonal transitions than by the loss of some grain, "Noise Reduction" can be a really useful addition.

Upscaling and digital image processing are not the RM7L's strong suit. TCL has used the MediaTek Pentonic 700 chipset here, designated MT5896, which is not among the best processors when it comes to handling lower-quality source material. The biggest problems appear with heavily compressed content from YouTube or standard broadcast TV. The processor cannot effectively hide posterization and the characteristic banding between tones. The feature intended to smooth these issues does little to help, and can also interfere with the image too much, smoothing, for example, faces or fine textures. For that reason it is best simply not to use it.

Standard upscaling to 4K looks better. Lower-quality content is sufficiently sharp and retains an adequate amount of detail. It is not on a par with the best processors on the market, but for everyday viewing the result is entirely acceptable.

Motion handling and motion clarity on the QN80H are really good, mainly thanks to the fast panel. In 4K the screen refreshes at up to 144 Hz, and when switched to Full HD and connected to a PC it can reach as much as 240 Hz. That's new for Samsung TVs and a useful addition for people who want to use the TV for PC gaming as well. We were more interested, however, in how the QN80H performs at 120 Hz, because consoles use that refresh rate. Here it performs very well. The panel does not suffer greatly from the smearing typical of VA panels, and light trails behind moving objects are mainly visible on dark backgrounds. That said, it's nothing that would interfere with normal watching of sport or gaming. The TV also has a motion smoothing system that Samsung calls "Wyrazistością obrazu". You can adjust judder reduction and blur reduction separately, so it's easy to tailor its behaviour to films, sport or your own preferences.

The RM7L features a 144 Hz VA panel, so from the outset it is well suited to sports, gaming and other fast-paced content. The high refresh rate also gives the motion interpolation more scope, allowing it to generate additional frames. On the RM7L it works well and, with the right settings, can noticeably improve motion smoothness without an excessive soap opera effect.

The Samsung QN80H is a TV that stands out when it comes to gaming features. The biggest new addition for 2026 is DLG mode, which allows refresh rates of up to 240 Hz when the image is switched to Full HD. It's an option aimed mainly at PC users, but it also shows that Samsung is still heavily developing the gaming side of its TVs. However, the list of advantages doesn't end there. The QN80H has four full-fledged HDMI 2.1 ports, which is still not standard at this price point. So you can connect several consoles, a PC or a soundbar at the same time without having to wonder which port supports the full video capabilities. The TV also supports VRR, ALLM and HGiG, so it's hard to fault its basic feature set.

A downside is the lack of Dolby Vision, which may matter primarily to Xbox Series X owners. However, this is not a flaw that disqualifies the QN80H as a gaming TV. Samsung has a feature most manufacturers still lack: its proprietary motion smoothing, Game Motion Plus. It's a motion smoothing system that works in game mode too, allowing you to improve the smoothness of titles running at 30 or 60 frames per second without a drastic increase in input lag. In practice, Game Motion Plus can make a much bigger difference than the Dolby codec, especially in more demanding games that don't offer a 60 FPS mode. The image becomes noticeably smoother, while controls remain sufficiently responsive. So despite the lack of Dolby Vision, the QN80H remains one of the best-equipped gaming TVs in its class.

The RM7L earns almost nothing but praise when it comes to features for gamers. The TV supports ALLM, VRR and Dolby Vision Gaming and works properly with HGiG, so it’s hard to point to any major omissions in that regard. In practice this means automatic switching to a low-latency mode, smoother motion at variable frame rates and accurate brightness reproduction in HDR games. There’s also a very useful Game Bar. From it you can quickly check frame rate, VRR status, signal format or aspect ratio, and change the key settings without leaving the game. TCL has also added a few extra options, such as a crosshair overlay and brightening of dark image areas, which can be handy in some titles. The biggest drawback stems from the use of the Pentonic 700 processor. Only two of the four HDMI ports support the full HDMI 2.1 standard. That won’t matter much with a single console, but if you connect two consoles and a PC you may run out of ports, especially since one of those ports may be needed for eARC and a soundbar.
