TCL RM7L vs Samsung The Frame Pro 2026 (LS03HW)

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.

You can't fault The Frame Pro for one thing: brightness. At peak we measured about 850-900 nits, so the TV has plenty of power to make many HDR scenes look really impressive. Bright, full-screen shots and more colourful frames perform best. In those scenes The Frame Pro can make a good impression — the image is bright, punchy and has the effect we expect from HDR. In our measurements some scenes reached over 800 nits, and even in tougher passages the TV maintained a fairly respectable brightness level.

The problem starts when HDR depends on small bright elements shown against a dark background. Single lamps, stars or reflections can be bright, but very often the black level across a larger part of the image also rises. As a result the bright point itself can look good, but the whole frame loses a lot of quality. That means The Frame Pro shows HDR best in scenes that are simply full-screen. If a film or series contains many such shots, the effect can be genuinely enjoyable. In darker material the limits of local dimming become much more noticeable.

Colours

The Frame Pro deserves praise for its colour gamut coverage. The TV uses quantum dots, the solution known as QLED, so it can deliver really well-saturated colours. In our measurements coverage of the important DCI-P3 palette was around 94.5%, while the more demanding BT.2020 was about 72%.

Those are very solid results that in most scenes produce pleasant, saturated colours. Of course they are not as eye-catching as the values from the latest panels using RGB backlights, but The Frame Pro makes up for that in another way — colour stability. Regardless of the scene, colour saturation remains fairly consistent and there aren't situations where the TV loses colour badly in more demanding frames.

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.

In SDR material The Frame Pro in Filmmaker mode performs quite well, though it falls short of perfect. White balance is relatively even, but as brightness increases the blue component diminishes, so brighter parts of the image can have a slightly warmer tint. A bigger difference is visible in the gamma, i.e. the screen’s brightness handling. Across most of the range it runs below our reference point, which means the TV brightens the midtones a little. As a result, the image can appear a little brighter and less contrasty than it should. The colour errors themselves aren’t huge, but they’re noticeable enough that calibration can still make a significant improvement.

In HDR content the white balance looks similar, being fairly even across much of the range, with larger deviations appearing only at higher brightness. The EOTF curve, however, is more revealing. The Frame Pro holds up fairly well against the reference values in the brighter parts of the image, but clearly lifts the darkest parts. This is primarily due to the TV’s backlight design. This also affects the colours. With less saturated colours the errors are still moderate, but they become significantly larger as saturation increases. In Colour Checker measurements many samples already show high error values. So the out-of-the-box HDR can be considered decent, but it’s definitely not an image we’d call very accurate.

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.

After calibration, the biggest improvements are seen mainly in SDR material. We managed to even out the white balance, but an even more important change was the gamma correction, which before calibration had the greatest effect on the picture's character. After the adjustments the gamma curve is now very close to the reference, so the image is not as bright in the mid-tones and simply looks more natural. Colour errors have also been noticeably reduced, so the effect of calibration in SDR is clearly visible.

In HDR the situation is a bit more complex. White balance was improved and in some ranges the TV tracks the reference much better, but at higher brightness levels deviations still appear. The same goes for colour reproduction; some errors can be corrected, but not all stem from the settings themselves. This reveals the limitations of the TV's design and the way its backlight and local dimming affect the HDR image. So with The Frame Pro, calibration makes the biggest difference to everyday content. Regular TV, YouTube and films and series in SDR (mainly those from cheaper streaming service tiers) can look noticeably better afterwards.

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 Frame Pro uses the NQ4 AI Gen3 processor, so in terms of image processing it behaves very similarly to other recent Samsung TVs. Upscaling works really well, with lower-resolution material being sensibly sharpened and the picture remaining readable without over-emphasising edges. With regular TV broadcasts or lower-quality YouTube content this can deliver a noticeable improvement, although viewers watching even older sources, such as VHS tapes, may notice a slight cropping on the left side (overscan).

It’s a different story for heavily compressed footage and the reduction of noise and posterization artefacts. The "Noise Reduction" feature can improve poorer material, but it fairly quickly starts to interfere with the picture and removes fine detail and film grain. So it’s best used sparingly and mainly when the source genuinely needs it.

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 Frame Pro is equipped with a 144 Hz panel and, when connected to a PC, also supports 240 Hz at Full HD. That's mainly a feature aimed at PC gamers, but the TV also handles the standard 120 Hz refresh rate used for watching sport or gaming on consoles very well. A major plus is the low smearing. For a VA panel, The Frame Pro performs really well in this regard. You don't see the strong, dark trails behind moving objects that are fairly common on TVs with this type of panel. That keeps fast sport and dynamic games clear in motion. There's also a motion smoothing feature with adjustable strength, so for films and sports broadcasts you can tailor the motion to your preferences. You can find our recommended settings in the photo.

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.

For gamers, The Frame Pro has a lot to offer. The TV supports 4K at 120 Hz, VRR, ALLM and a correctly implemented HGiG. When connected to a PC you can also run 144 Hz at 4K, and even 240 Hz if you drop to Full HD. Samsung also bundles its usual set of gamer extras: an expanded Game Bar that lets you quickly view and change the key settings, and Game Motion Plus to improve smoothness for games running at 30 or 60 fps. There’s also the Gaming Hub and the ability to play in the cloud without needing to connect a console. The only real omission is Dolby Vision Gaming, which Samsung doesn’t support. Aside from that, The Frame Pro offers pretty much everything you’d expect from a well-equipped gaming TV today.
