TCL C855 vs Samsung The Frame Pro 2026 (LS03HW)

The TCL C855 delivers a highly varied HDR effect. At times, the television truly excels, while at other moments, it appears reminiscent of a low-end model equipped with FALD backlighting. Inconsistency is frequently found with this brand, so it didn’t come as a surprise. The first and last scenes, which feature large light elements, are nothing short of spectacular, boasting brightness levels of 1470 and 1820 nits, respectively. Such brightness can make viewers squint their eyes, allowing them to feel the extraordinary dynamism of the scene. It genuinely immerses the audience, creating a sensation of being inside the movie itself. However, the situation shifts dramatically when small or subtle elements with high luminance appear against a dark background. In these instances, the TCL C855 significantly reduces brightness to levels as low as 240 nits to mitigate halo effects. This reduction is disappointing, as it can make the movie appear as if it was not filmed in HDR. Despite these shortcomings, the HDR effect on the TCL C855 enhances the viewing experience during dynamic scenes, making it feel more engaging and allowing the viewer to feel part of the action. Even with smaller high-luminance elements, the television retains details without excessive dimming. Additionally, the TCL C855 adjusts image brightness according to scenes with rich detail, further enhancing viewing comfort.

You can't deny The Frame Pro one thing: brightness. We measured a maximum of around 850 to 900 nits, so the TV already has enough power to render many HDR scenes really impressively. Bright, full-screen shots and more colorful frames look best here. In those scenes The Frame Pro can make a good impression because the image is bright, strong, and delivers the effect we expect from HDR. In our measurements some scenes reached over 800 nits, and even in trickier sections the TV maintained a fairly decent brightness level.

The problem starts when HDR relies on small bright elements shown against a dark background. Individual lamps, stars, or highlights can be bright, but very often the black level across much of the image also lifts. As a result, the bright point itself may look good, but the whole frame loses a lot of quality. That is why The Frame Pro shows HDR best in scenes that are simply full-screen. If a movie or series contains many such shots, the effect can be really enjoyable. In darker material the limitations of local dimming become much more noticeable.

Colors

The Frame Pro deserves praise for its color gamut coverage. The TV uses quantum dots, a solution known as QLED, which allows it to produce very well-saturated colors. In our measurements coverage of the important film color space DCI-P3 was about 94.5%, while the more demanding BT.2020 was around 72%.

Those are very solid results that in most scenes deliver pleasant, saturated colors. Of course, these values are not as striking as those in the latest displays using RGB backlighting, but The Frame Pro makes up for that with something else: color stability. Regardless of the scene, color saturation remains fairly consistent, and there is no situation where the TV loses a lot of color in more demanding shots.

The best factory mode for the TCL C855 is the "Film" setting, and all our tests were conducted using this mode. However, like many predefined modes, it has flaws that should be addressed to achieve an image closer to the producer's original vision. In our examination of the colour characteristics for both SDR and HDR materials, issues were found.

Focusing first on SDR content, there is a noticeable dominance of green in the white balance, which leads to an unpleasant greenish tint across the entire image. The gamma chart, crucial for image contrast, shows a significant deviation from the reference line marked at 2.4. Initially, there is a pronounced spike in the measured value, resulting in an over-contrasted image where details can merge into a dark blob. This condition persists for nearly 20% of the chart before it dips below the reference line, causing the image to brighten and resulting in a substantial drop in contrast.

In HDR materials, the factory mode performs somewhat better; the white balance appears more balanced overall, although the green tint resurfaces in the latter half of the spectrum. When we look at the Electro-Optical Transfer Function (EOTF) curve—unlike gamma, which reflects contrast—we identify two main errors: the darkest scenes are too dark, while the brightest ones become overexposed. This discrepancy was evident in our review of the scene from the movie "Pan," further illustrating the TCL C855's HDR performance issues.

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 starts to drop, so brighter parts of the image can have a slightly warmer tint. A bigger difference is visible in the gamma, that is how screen brightness is managed. Across most of the range it runs below our reference point, which means the TV brightens midtones a bit. As a result the image can appear slightly brighter and less contrasty than it should. The color errors themselves are not huge, but they are visible enough that calibration can still make a substantial improvement. In HDR content the white balance looks similar: across much of the range it is fairly even, with larger deviations appearing only at higher brightness. The EOTF curve is more revealing. The Frame Pro follows reference values fairly well in the brighter parts of the image, but noticeably brightens the darkest portions. This stems mainly from the TV’s backlight design. That also affects colors. With less saturated colors the errors are still moderate, but they grow significantly as saturation increases. In ColorChecker measurements a large portion of samples already register high error values. The out-of-the-box HDR can therefore be considered decent, but it is definitely not an image we would call very faithful.

TCL, like most manufacturers, offers advanced calibration tools within its televisions. These include both 2-point and 20-point adjustments for grayscale, as well as a comprehensive colour management system. As a result, we achieved impressive results in SDR materials, bringing the image significantly closer to the reference standard. We successfully eliminated both the green tint and the gamma issue, although a slight "kink" at the very beginning of the gamma curve still persists.

In contrast, the situation with HDR materials was less favourable, as the TCL C855 did not allow for precise modelling. We were only able to make minor adjustments to the EOTF curve while significantly enhancing the overall colour accuracy. This limitation suggests that while calibration tools are effective, they may require further refinement for optimal HDR performance.

After calibration the biggest improvement is visible primarily in SDR content. White balance was evened out, but the more important change was the gamma correction, which before calibration had the greatest impact on the picture's character. After adjustments the gamma response is now very close to the reference, so the image is not as bright in the midtones and simply looks more natural. Color 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 over part of the range the TV tracks the reference much better, but deviations still appear at higher brightness levels. The same applies to color reproduction, as some errors can be corrected but not all result from the settings themselves. This reveals the limitations of the TV's design and the way the backlight and local dimming affect the HDR image. That's why, for The Frame Pro, calibration makes the biggest difference for everyday content. Regular broadcast TV, YouTube, and SDR movies and series (mainly those from cheaper streaming tiers) can look noticeably better after calibration.

Once again, we will take a look at the function of smoothing tonal transitions, but this time also image scaling. The latter is particularly important when watching materials of lower quality, such as some television programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes from the previous test where it performed excellently and smoothed out practically all the inconsistencies, here it had issues. Using the menu responsible for the operation of this function, we found that no setting—even the strongest—was helpful.

Image scaling in TCL C855 is defined as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural to our eye. Even small, fine branches do not have jagged edges, and there is no white halo around figures, a characteristic of weaker scaling systems.

The Frame Pro uses the NQ4 AI Gen3 processor, so in terms of image processing it behaves very similarly to Samsung's other recent TVs. Upscaling works really well; lower-resolution material is sensibly sharpened and the image remains clear without overemphasizing edges. With regular broadcast TV or lower-quality YouTube clips, this can provide a noticeable improvement, although viewers watching much older material, for example from VHS tapes, may notice a slight left-side cropping (overscan).

It's a bit different when it comes to improving more heavily compressed images through noise reduction and artifact suppression for issues like posterization. The "Noise Reduction" function can improve weaker material, but fairly quickly it starts to interfere with the image and remove fine detail or grain. So it's best used sparingly and mainly when the source truly needs it.

The maximum refresh rate you can set on the TCL C855 is 144 Hz. Naturally, this is only possible after connecting the TCL C855 TV to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we want to watch primarily sports or materials with a lot of motion dynamics. For those who require high image fluidity, the manufacturer has implemented a multi-stage motion smoother. It is divided into two separate sliders which control the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be adjusted from 0 to 10, with each level affecting the degree of fluidity, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect. The matrix of the TCL C855 features a very good response time. This is particularly important since VA panels often struggle with the so-called ghosting effect, where a black halo can be observed behind a fast-moving object. where a black halo can be observed behind a fast-moving object.

The Frame Pro is equipped with a 144 Hz panel and, when connected to a PC, also supports 240 Hz at Full HD resolution. That’s, of course, a feature aimed mainly at PC gamers, but the TV also performs very well at the standard 120 Hz refresh rate we use for watching sports or playing on consoles. A big plus is its minimal motion blur. For a VA panel The Frame Pro does really well in this regard. You don’t see strong, dark trails following moving objects that are fairly common on TVs with this type of panel. As a result, fast sports and dynamic games remain clear in motion. It also includes motion smoothing with adjustable smoothness, so for movies and sports broadcasts you can tune the motion character to your preferences. Our recommended settings can be found in the photo.

The TCL C855 TV has fully-featured HDMI 2.1 ports, boasting a full bandwidth of 48 Gb/s. During our testing, we confirmed the seamless operation of all functions included in this connection standard. As highlighted, all checkboxes are illuminated in green, a feature that will undoubtedly be appreciated by gamers, whether on consoles or those using the TV as a computer monitor. Additionally, the TCL C855 supports both AMD FreeSync and NVIDIA's G-Sync, which can be easily activated in the graphics card settings. Those with powerful configurations can feed a 144 Hz signal to the C855, which handles this effortlessly. It is also worth noting the implementation of the HGIG mode, which can be excessively bright due to the shortcomings of the "Game" mode, making proper configuration on the screen challenging. Fortunately, the TV excels with the Dolby Vision format.

TCL, as one of the pioneering manufacturers, has equipped its televisions with a special GameBar, allowing for extensive adjustment of settings "on the fly" without the need to exit the game. This feature includes options like an additional crosshair grid, black level correction, and settings designed for individuals with disabilities. The image showcases the next generation of this solution.

In summary, the TCL C855 TV is an ideal choice for those seeking a screen for all forms of electronic gaming. With comprehensive features supporting such entertainment, it provides an extremely engaging experience. It is also important to emphasise that it maintains very low input lag, regardless of the selected settings, including when using the Dolby Vision HDR format.

Function-wise for gamers The Frame Pro has a lot to offer. The TV supports 4K at 120 Hz, VRR, ALLM and correctly implemented HGiG. When you connect a PC you can also use 144 Hz at 4K, and even 240 Hz if you drop to Full HD. Samsung also adds its standard set of gaming extras: a robust Game Bar that lets you quickly view and adjust key settings, and Game Motion Plus, which can improve the smoothness of 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. Otherwise The Frame Pro offers practically everything you can expect today from a well-equipped gaming TV.
