Hisense UR9S vs TCL RM7L

Hisense UR9S is without doubt a show of force from the Chinese manufacturer when it comes to luminance. On a synthetic test pattern the panel hit as much as 2600 nits, which is an impressive result. But it’s important to clearly separate laboratory results from filmic realities. In real-world content the UR9S behaves much more restrained. Peak brightness in balanced scenes hovers around 1500 nits. In demanding, dark shots, where algorithms must both preserve deep blacks 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 conservative local dimming behaviour. When a bright object occupies a large part of the frame, the system can easily maintain a high brightness level. However, in night scenes the priority becomes protecting blacks and fighting halo artefacts (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, engaging HDR effect that impresses in bright, spectacular sequences.

Colour gamut coverage

On test patterns the Hisense UR9S performs excellently in terms of colour. DCI-P3 coverage is almost 100%, and the wide BT.2020 as much as 93%. Those are figures even the best QD-OLED TVs don't reach. But again, synthetic measurements are one thing, films and series are another. In real-world scenes the figures dropped 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 promise in marketing materials. One could even say their capability is now close to that of quantum-dot-equipped TVs, the so-called QLEDs. So why is that? To a large extent, colour reproduction here depends on the way the backlight zones operate. When a strongly saturated colour appears next to white or another, more complex element, a single zone must handle both parts of the image at once. Under such conditions the backlight can't maintain extreme saturation of a given colour on the screen, because the emitted light takes on a character closer to white. 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’s noticeably less than the C7L, which can get close to 2600 nits, but in real-world film scenes the difference between the models isn’t that large. In less demanding shots, where plenty of bright elements appear on screen, the RM7L can sustain around 1000 nits, and sometimes even a bit more, approaching 1500 nits. It performs worse in dark scenes with small points of light; then their brightness can fall to about 500 nits. This behaviour isn’t random. The TV deliberately dims small elements to better control the backlight and preserve higher contrast. This comes at the expense of their intensity, but it’s typical for TVs with local dimming in a similar price range.

Colour gamut coverage

In HDR brightness isn’t the only thing that matters, colour does too. Here the RM7L has a lot to show. Colours are strongly saturated and the wide colour gamut is one of its main strengths. In our 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 colours look best, while in films their saturation can be a little lower than on SQD Mini LED or QD-OLED TVs. The backlight design itself is interesting. The RM7L doesn’t use the classic red, green and blue LED set. TCL used two green LEDs and one blue, with red produced via a PFS phosphor. You can see this in spectrometer measurements, but it doesn’t 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. In HDR content the TV performed quite well in that regard. The white balance didn't show major errors, and the brightness response, while following Hisense's typical curve, was kept at a reasonable level. The picture therefore wasn't overly brightened or noticeably colour-distorted. The same mode fared much worse with SDR content, the kind we watch most often, like broadcast TV or YouTube. The white balance was strongly shifted toward red and blue, giving the image a slightly pink tint. This also affected the gamma curve. Instead of approaching the reference value of 2.4, it was closer to 2.0, which made the image look too bright, especially in midtones and darker areas. Filmmaker Mode therefore remains the best out-of-the-box choice, but it's not without flaws.

Factory colours were checked 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 reproduce the image as faithfully as possible to the filmmakers' intent. On the RM7L it was indeed the best calibrated mode, though not without faults. The biggest issue was the white balance. An excess of red and blue made the image shift slightly toward pink tones. This was visible in both SDR and HDR. In addition, the brightness response was slightly boosted, so the picture looked a little brighter but at the same time less contrasty than it should.

After calibration, the biggest improvement was in SDR, although we also refined the HDR picture. Hisense offers plenty of calibration controls in the menu, so we were able to precisely correct the white balance and other picture errors. The most important change was removing the pink cast that had been clearly visible in SDR material. After calibration the image looks much more natural, especially in everyday content like TV and YouTube. Colour reproduction errors on the ColorChecker chart are very small after calibration. The vast majority of colours fall below values of 2–3, which is at a level very hard for the human eye to detect. The only thing we couldn't completely eliminate is the way Hisense TVs map tones in HDR. It affects how brightness is distributed in films and can subtly 'beautify' the image, rather than strictly following the creators' intent. For less experienced viewers this can create a stronger 'wow' effect, but it won't always fully match how the material should look.

Thanks to a fairly extensive calibration menu we managed to correct the vast majority of the issues described earlier. The biggest change was the white balance. After calibration it looks very good, so the image has lost its pinkish tint and become 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 bright, and darker parts look more natural and have greater depth. Better luminance accuracy has also affected the colours, 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 in its own way and doesn’t always stick exactly to the reference curve. You can see this mainly in some darker scenes, where the TV can either slightly lift the shadows or darken them completely. That’s where the earlier impression of a slightly brightened, less contrasty image came from. Even so, the calibration delivers a very good result here. It removes the most visible errors and, above all, makes the picture much closer to how it should look.

Digital image processing has been one of Hisense's strengths for the past two years, and the UR9S is no different. The manufacturer uses the Hi-View AI Engine RGB processor, which in practice is based on the well-known MediaTek Pentonic 800 platform, previously used in models such as the U8Q. The TV handles upscaling lower-resolution material to 4K very well, and copes with low-bitrate content, where various compression artefacts can easily appear. Thanks to a function called "Smooth and gradient image", the picture stays detailed without looking overly sharpened or artificially smoothed. When watching regular broadcast TV or older, lower-quality material, the UR9S can get a surprising amount out of it. In terms of digital image processing, this is one of the most finely tuned LCD TVs we've had the chance to test.

Upscaling and digital image processing are not the RM7L’s strong points. TCL has used a MediaTek Pentonic 700 chipset here, labelled MT5896, which isn’t among the best processors at handling lower-quality sources. The biggest issues appear with heavily compressed content from YouTube or regular broadcast TV. The processor can’t effectively hide posterisation and the characteristic banding between shades. The feature meant to smooth these issues does little to help and can also interfere with the picture too much, smoothing faces and fine textures, for example. For that reason it’s best not to use it.

Plain upscaling to 4K looks better. Lower-quality sources are reasonably sharp and retain a sufficient amount of detail. It’s not on a par with the best processors on the market, but for everyday viewing the result is perfectly acceptable.

The Hisense UR9S is one of the first TVs on the market with a 4K panel and a 170 Hz refresh rate. In the larger sizes, 75 and 85 inches, that goes up to 180 Hz. Such a high refresh rate will mainly benefit owners of very powerful computers. Films and TV series are still most often watched at 24 fps, and sports broadcasts at 50 fps, so in everyday use the panel's response time and the behaviour of the motion smoothing are more important. In that respect the UR9S performs very well. Panel motion blur is low, as our UFO test also confirmed. Moving objects do not leave a pronounced smear, so the picture remains clear even in fast scenes.

The RM7L uses a 144 Hz VA panel, so right from the start it's well prepared for sports, games and other dynamic content. The high refresh rate also gives the motion interpolation more room to work, so it can generate additional frames. On the RM7L it performs well and, when set correctly, can noticeably improve motion smoothness without producing an excessive soap opera effect.

The Hisense UR9S is very well set up 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. You also get VRR, ALLM, NVIDIA G-Sync and AMD FreeSync, so it's hard to fault the basics. PC gamers can additionally enable DLG mode. After switching the resolution to Full HD the refresh rate can rise up to 330 Hz. That's more of an option for a narrow group of users, but it shows how much headroom the panel has. Hisense also added a Game Bar, where you can quickly change the main settings, check the refresh rate, or enable a crosshair and minimap zoom.

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

When it comes to gamer-focused features, there's almost nothing but praise for the RM7L. The TV supports ALLM, VRR, Dolby Vision Gaming and works correctly with HGiG, so it's hard to point to any major gaps in that area. In practice that means automatic switching to a low-latency mode, smoother motion 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 has added a few extra options too, such as an on-screen reticle and brightening of dark areas, which can be useful in some titles. The biggest downside comes from using the Pentonic 700 processor. Only two of the four HDMI ports support the full HDMI 2.1 standard. With a single console that won't be a big issue, but if you hook up two consoles and a PC you might run out of ports, especially since one of those ports may also be needed for eARC and a soundbar.
