Hisense UR9S vs TCL RM7L

Hisense UR9S is undoubtedly a show of strength from the Chinese manufacturer when it comes to luminance. On a synthetic test pattern the panel reached as much as 2600 nits, which is an impressive result. However, it is important to clearly separate laboratory results from filmic realities. In real material the UR9S behaves much more... restrained. Maximum brightness peaks in balanced scenes hover around 1500 nits. In demanding, dark shots, where algorithms must at once maintain deep black and precisely light small details, brightness can fall drastically, even to around 400 nits. The discrepancy between the chart and reality is therefore huge. This is a direct consequence of the conservative behaviour of the local dimming system. When a bright object occupies a large part of the frame, the system can easily sustain a high brightness. But in night scenes the priority becomes protecting black and combating the halo effect (unsightly glows around bright edges). To avoid contrast degradation, the TV drastically limits light output. Even so, the UR9S can still produce a very powerful, immersive HDR effect that impresses in bright, spectacular sequences.

Colour gamut coverage

On test patterns the Hisense UR9S performs excellently in terms of colour. Its coverage of the DCI-P3 gamut is almost 100%, and the wide BT.2020 as much as 93%. Those are results even the best QD-OLED TVs do not achieve. But again, synthetic measurements are one thing, films and series another. In real-world scenes the figures fell to 93% for DCI-P3 and 81% for BT.2020. That's still a great result, but the advantage of RGB Mini LED is no longer as dramatic as manufacturers claim in their marketing materials. One could even say that currently their capability is similar to TVs equipped with quantum dots, the so-called QLED. So why does this happen? To a large extent colour reproduction here depends on the specifics of how the backlight zones operate. When a strongly saturated colour sits next to white or another, more complex element, a single zone has to handle both parts of the picture at once. Under those conditions the backlight cannot maintain extreme saturation of a given colour on screen, because the emitted light takes on a more white-like character. In the UR9S this has been refined quite well, but still not enough for the TV to maintain such high colour saturation in every situation.

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.

We tested the Hisense UR9S in Filmmaker Mode, which out of the box provides the best image reproduction. With HDR material the TV performed quite well in this regard. The white balance showed no major errors, and the luminance response, although it had the characteristic Hisense profile, was maintained at a reasonable level. The picture was therefore neither excessively brightened nor noticeably colour-distorted. The same mode performed much worse with SDR material, the kind of content we watch most often, such as broadcast television or YouTube. The white balance was strongly shifted towards red and blue, giving the picture a slight pink tint. This also affected the gamma curve. Instead of approaching the reference value of 2.4, it was closer to 2.0, making the image look too bright, particularly in midtones and darker areas. Filmmaker Mode therefore remains the best out-of-the-box choice, but it is not a mode without faults.

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.

After calibration the biggest improvement was in SDR mode, although we also refined the HDR picture. Hisense offers a lot of calibration settings in the menu, so we were able to precisely correct the white balance and the remaining image errors. The most important change was removing the pink tint that had previously been clearly visible in SDR material. After calibration the picture looks much more natural, especially in everyday content such as TV or YouTube.

Colour reproduction errors on the ColorChecker chart are very small after calibration. The vast majority of colours fall below values of 2 to 3, which is at a level very difficult to discern with the human eye. The only thing we could not completely eliminate is the tone-mapping approach characteristic of Hisense TVs in HDR. It affects how brightness is distributed in films and can subtly 'enhance' the image, rather than sticking exactly to the creators' intent. For less experienced viewers this can produce a stronger 'wow' effect, but it will not always fully match how the material 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.

For the past two years digital picture processing has been one of Hisense's strengths, and the UR9S is no exception. The manufacturer uses the Hi-View AI Engine RGB processor, which in practice is built on the well-known MediaTek Pentonic 800 platform, previously used, among others, in the U8Q model. The TV handles upscaling lower-resolution material to 4K very well, and copes with low-bitrate content where compression artefacts are common. Thanks to a feature called "Smooth and Gradient Picture", the image remains detailed without appearing over-sharpened or artificially smoothed. When watching regular broadcast TV or older, lower-quality material, the UR9S can get a surprising amount out of them. In terms of digital picture processing, this is one of the most refined LCD TVs we've had the chance to test.

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.

The Hisense UR9S is one of the first televisions on the market with a 4K panel and a 170 Hz refresh rate. In the larger sizes, 75 and 85 inches, this goes up to 180 Hz. However, such a high refresh rate will be useful mainly to owners of very high-performance PCs. Most films and TV series are still watched at 24 fps, and sports broadcasts at 50 fps, so for everyday use panel response time and the operation of the motion smoothing are more important. In that respect the UR9S performs very well. Panel smearing is minimal, as confirmed by our UFO test. Moving objects do not leave a pronounced trail, so the picture remains clear even in fast scenes.

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.

Hisense UR9S is very well prepared for gaming. All three HDMI ports are HDMI 2.1 and offer the full 48 Gb/s bandwidth. The TV supports 4K at 170 Hz, and on larger screen sizes even 180 Hz. It also includes VRR, ALLM, NVIDIA G-Sync and AMD FreeSync, so in terms of basic features there is little to criticise. PC gamers can additionally enable DLG mode. After switching the resolution to Full HD the refresh rate can increase to as much as 330 Hz. That's probably an option for a relatively small group of users, but it shows how much headroom the panel has. Hisense has also added a Game Bar that lets you quickly change key settings, check the refresh rate or enable an on-screen crosshair and minimap zoom.

The biggest drawback remains the lack of a properly working HGiG. The TV still uses its own tone mapping, which makes configuring HDR on a console a bit more difficult. In our case values around 1500 to 2000 nits worked best, but it's worth checking which setting keeps all the detail in the brightest parts of the image.

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.
