TCL C655 Pro vs LG UA75006LA (VA)

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, the limited number of dimming zones causes some issues. 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 more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, which, like in the version without the PRO suffix, is at a very good level.

LG UA7500 with a VA panel has brightness peaking 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 to boost highlights. One advantage is that regardless of the test content, the effect remained relatively stable. However, we noticed that in very extreme scenes with a lot of fine details, the television can slightly dim the image in order to achieve better blacks, but this comes at the expense of the visibility of bright effects. On the downside, it should be noted that the UA7500 is not equipped with any additional technologies to expand the colours. It's neither a QLED panel nor PFS LED, which means the coverage of the DCI-P3 colour gamut is just 80%, making many HDR films look flat and failing to capture the full diversity of colours.

Each of our TV tests is conducted in movie mode, which usually offers the best colour reproduction. However, even this mode is not free from issues, as we noted in 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 overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have 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 image is reasonably well put together and at first glance doesn't irritate, however, its weaknesses quickly start to emerge. This is most apparent in scenes with bright points – lamps in the background or reflections of light on the skin are clearly exaggerated. Faces of characters often look unnatural, as if they have been "burned out." Additionally, the default gamma setting brightens the smallest details and causes the image to lose subtlety in the darker areas. That said, for its price range, the UA7500 in factory mode offers a pretty decent starting point. However, it is clear that without additional adjustments, these issues cannot be avoided, which is why – similar to other TVs – we decided to check what could be achieved after calibration.

After calibrating the TCL 655 PRO television, there is a noticeable improvement in white balance, where the tendency for the screen to be overly pink has been completely eliminated, which was previously noticeable in factory mode. The picture has taken on more natural tones, especially in white and bright elements, which positively affects the overall image perception. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image appear washed out. Nevertheless, there are still some issues with the EOTF curve, which are difficult to eliminate due to the television's construction and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. However, despite this minor fault, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

The biggest improvement we noticed was while calibrating the mode designed for daily SDR content. We managed to smooth out the white balance in an acceptable manner and tackle the issue of excessive brightening of small elements due to the gamma characteristic. As a result, the image gained the consistency and naturalness that was lacking in the factory settings. After such correction, we can confidently state that for everyday TV content, programs, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation looks a bit different for HDR content. Here, calibration helped to tame the white balance and slightly improved brightness management, but the limitations of the design are immediately apparent. The lack of additional filters to expand the colour palette means that the most vivid colors appear flat, and the image lacks the intensity we would expect from good HDR. So, in SDR, the UA7500 performs quite well, 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 quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

LG UA7500 with a VA panel has shown itself in this category in a really good light. Image scaling from Full HD or even SD materials was surprisingly smooth. The picture looked smooth, edges were not overly jagged, and the television maintained a good amount of detail, ensuring that even older films did not lose their character. It particularly excelled with faces – there were no artificial contours or "mask" effects, which often occur in cheaper models. The way the television handled tonal transitions in lower quality materials is also noteworthy. Thanks to digital processing, colours did not bleed into one another, and gradients looked natural and smooth. There was no question of intrusive smoothing of the image or loss of cinematic grain. This makes the UA7500 great for everyday content – from free-to-air television, to sports matches, all the way to YouTube, where we often watch materials in various resolutions.

The TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, albeit at the cost of lower resolution.

LG UA7500 is a TV with a 60 Hz panel, so it’s hard to expect any raving reviews in this category. It’s more of a screen meant for everyday content or an evening movie session rather than for following dynamic sporting events or playing action games. It's evident that the manufacturer targeted this model precisely at this group of consumers – and in that regard, it performs adequately. We get the TruMotion function, which is a motion smoother. It’s simple, has only one slider, but it can make a noticeable difference. In the lower range, the image looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasant to the eye.

The TCL C655 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation in games that support this format, while the Game Bar provides quick access to essential settings, such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.

LG UA7500 is a TV that can be comfortably recommended to "Sunday" gamers. While it doesn't feature a 120 Hz panel or HDMI 2.1 ports, meaning it can't fully utilise the potential of modern consoles, the manufacturer has included a few extras that can enhance the gaming experience. The Game Bar deserves a special mention – a very nicely designed panel where you can quickly view and change the most important settings. From this interface, we have access to features like ALLM (Automatic Low Latency Mode) and frame synchronization, also known as VRR. The range of VRR is limited – working from 48 to 60 Hz – but the mere presence of this feature in such an affordable TV is impressive.

Additionally, it supports HGiG, which is a mode for HDR calibration for gaming. It sounds good, but from our testing experience, we know that for the UA7500, this option isn't very practical. The TV doesn't handle HDR very well, so ironically, we achieved better results with this mode turned off. This is another indication that the UA7500 is more of a screen for casual gamers who value simplicity and convenience, rather than for those seeking a full experience with the latest consoles.
