TCL C655 Pro vs LG UA75006LA (VA)

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

The LG UA7500 with a VA panel has a brightness that hovers around 350 nits, which, by today’s standards, isn't very impressive. It's hard to talk about a true HDR experience here – most content looks more like classic SDR with a slight attempt at highlights enhancement. One advantage is that regardless of the test pattern, the effect remained relatively stable. However, we noticed that in very extreme scenes with a lot of fine detail, the television can slightly dim the image to achieve better black levels, but this comes at the cost of visibility of bright effects. Additionally, it should be noted that the UA7500 is not equipped with any extra technologies for expanding color. It is neither a QLED panel nor a PFS LED, which is why the coverage of the DCI-P3 color palette is only 80%, causing many HDR movies to appear flat and not fully represent the variety of colors.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with the TCL 655 PRO model.

In the case of HD content, the white balance clearly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation looks better, but there is a tendency to excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

The Filmmaker mode on the LG UA7500 performs better than one might expect from such a budget TV, but let's not get carried away with the praise. The picture is put together quite sensibly and at first glance is not irritating; however, its weaknesses quickly start to show. This is most apparent in scenes with bright points – lamps in the background or reflections of light on the skin are clearly exaggerated. Characters' faces often look unnatural, as if they have been "burned out." Additionally, the default gamma settings brighten even the smallest details, causing the image to lose subtlety in darker areas. Nevertheless, the fact remains that, for its price range, the UA7500 in factory mode provides a decent starting point. However, it's clear that without additional correction, these issues cannot be avoided, which is why – as with other TVs – we decided to check what could be achieved after calibration.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

We noticed the greatest improvement when calibrating the mode intended for daily SDR content. We managed to smooth the white balance in an acceptable way and tackle the issue of excessive brightening of small elements by the gamma characteristic. As a result, the image gained the consistency and naturalness that were lacking in the factory settings. After such correction, we can confidently state that for daily television content, programs, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation is somewhat different for HDR content. Here, the calibration did allow us to tame the white balance and slightly improve brightness management, but the limitations of the design are immediately apparent. The lack of additional filters to widen the color palette means that the most vivid colors appear flat, and the image does not have the intensity we would expect from good HDR. In SDR, the UA7500 performs quite decently, but in HDR – despite corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

The LG UA7500 with a VA panel has shown a really good performance in this category. The image scaling from Full HD content or even SD was surprisingly smooth. The picture looked smooth, edges weren't excessively jagged, and the television maintained a significant amount of detail, which meant that even older movies didn't lose their character. It particularly excelled with faces – there were no artificial contours or the "mask" effect, which often occurs in cheaper models. The way the television handled tonal transitions in lower-quality materials is also noteworthy. Thanks to digital processing, colors didn't blend together, and gradients looked natural and smooth. There was no intrusive image smoothing or loss of cinematic grain. This makes the UA7500 great for everyday content – from terrestrial television, through sports, to YouTube, where we often watch materials in various resolutions.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

LG UA7500 is a television with a 60 Hz panel, so it’s hard to expect any awe in this category. It’s more of a screen intended for everyday content or an evening movie session rather than for following dynamic sports events or playing action games. It’s clear that the manufacturer directed this model specifically to that group of consumers – and in that regard, it performs correctly. We have the TruMotion function at our disposal, which is a motion smoother. It’s simple, has only one slider, but it can make a noticeable difference. At lower settings, the image appears more raw and cinematic, while at higher values, motion becomes smoother and more pleasing to the eye.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.

LG UA7500 is a television that can be safely recommended to "casual" gamers. While it does not have a 120 Hz panel or HDMI 2.1 ports, so fully utilizing the potential of modern consoles is out of the question. However, the manufacturer has taken care to include a few extras that can make gaming more enjoyable. Notably, the Game Bar deserves mention – a very nicely designed panel where you can quickly view and change the most important settings. From this panel, we have access to features such as ALLM (automatic switching to game mode) and frame synchronization, which is VRR. The range of VRR is limited – it works from 48 to 60 Hz – but the mere presence of this feature in such an affordable television leaves a positive impression.

Additionally, there is support for HGiG, which is HDR calibration mode for gaming. It sounds good, but based on testing experiences, we already know that with the UA7500, this option doesn't make much sense. The television does not handle HDR very well, so paradoxically we achieved better results with this mode turned off. This is another signal that the UA7500 is more of a screen for occasional gamers who value simplicity and convenience rather than for those looking for full immersion from the latest consoles.
