Our verdict

LG UR781 is currently the cheapest model from the Korean manufacturer. It features an excellent WebOS system, which is the main advantage of this television. It satisfies most users with access to various streaming platforms and capabilities. The TV offers adequate picture quality for its price, which will certainly meet the expectations of many basic users. Although its HDR capabilities are somewhat limited by the lack of Dolby Vision or HDR10+, it supports basic formats such as HDR10 and HLG. The television handles low-quality content quite well, thanks to the smooth transition smoothing feature, which provides smooth and clear transitions, particularly appreciated when watching films from low-quality sources (e.g., free-to-air television). When it comes to gaming, the television has a very low input lag, which is a fundamental criterion. If we are looking for a budget option, it is quite a nice choice for those willing to compromise on a 120Hz panel for the sake of price. Although the brightness of the television is lower than in competing models, and the colour gamut coverage is limited, the LG UR781 still offers impeccable HDR content appearance due to the presence of dynamic tone mapping. With proper calibration, the television can achieve better colour reproduction and optimal sharpness, significantly enhancing comfort and enjoyment while watching.

The mid-range television segment is expanding rapidly, and TCL C75B demonstrates that it’s possible to get really solid equipment in this price category. This model is clearly designed with gamers in mind – the HDMI 2.1 port offers a lot of potential, providing VRR, ALLM, and impressive 144 Hz refresh rate in 4K (or 240 Hz in Full HD), which will certainly please both gaming and sports fans. The TV’s operation is pleasant and intuitive, mainly thanks to the Google TV system. While there may be minor stutters, the wealth of available apps and features more than compensates for this – practically everything we need is at our fingertips or even at the sound of our voice if we wish to talk to the remote in Polish. As for picture quality, TCL C75B also performs well. Thanks to the VA panel, it boasts quite good contrast, and the presence of Dolby Vision allows for enjoyable HDR effects, even if the brightness isn’t mind-blowing. Of course, it isn't without its flaws – despite the fast panel, there is some motion blur, and the lack of traditional features (like USB recording) may disappoint some users. Nevertheless, in its price category, the C75B is a very attractive option, especially for those looking for a screen designed for high-level gaming.

Halo effect and black detail visibility:

LG UR781 is a TV with a VA panel that stands out for its good native contrast, significantly better than that of IPS or ADS screens. Thanks to this technology, bright elements on a dark background look natural and there is no issue with distortion. Unfortunately, the lack of local dimming means that in darker rooms, the blacks are not ideal – they take on a bluish hue, which can be noticeable during nighttime viewing.

Despite this, the LG UR781 offers sufficiently good quality in dark scenes, especially for movie fans. The blacks are deeper than those of IPS panels, allowing for a more cinematic experience. The VA panel also provides stronger contrast, making the image look sharper and details in darker shots more visible. It's a solid choice for those who appreciate better picture quality in evening conditions.

The TV we tested, TCL C75B in size X," is equipped with a VA panel, which naturally provides quite decent contrast results – and that’s what we observed during our tests. On each test pattern, the TV achieved a contrast level of around 5500:1. This is a result that can be considered very good in this price category. The black in this model performs really well, though of course, it’s far from perfect.

Due to the C75B belonging to the mid-range segment, we won’t find local dimming technology here. This is particularly noticeable in more demanding scenes, such as those from the film Sicario 2, where we noticed that the black takes on a navy hue instead of a pitch-black. This limitation of panels without local dimming can be particularly evident in evening viewings with the lights off, when dark elements of the image are more pronounced. It's worth keeping this in mind when choosing a TV in this category, especially if we care about the best quality of black while watching movies at night.

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

After calibration

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

TCL C75B offers various picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the TV struggles with certain colour reproduction issues. In tests, we noticed that the image had a noticeably pinkish hue compared to what could be considered correct. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit of this phenomenon turned out to be the white balance, characterised by an excess of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

Color reproduction after calibration

6/10

8.2/10

After calibration, colour reproduction in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across different scenes. The gamma has also been adjusted, providing a more precise representation of details in the shadows and bright areas of the image. As a result, the LG UR781 TV performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

After calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

Smoothness of tonal transitions

8.6/10

8.2/10

TV LG UR781 handles tonal transitions exceptionally well, delivering very high picture quality in all scenes. Issues with gradation only arise in darker colours; however, they are subtle and not glaringly obvious. People with particularly sensitive eyes may notice these imperfections, but overall, the television provides very smooth tonal transitions.

When it comes to tonal transition fluidity, TCL C75B performs really well. It particularly excels in gradation of the darkest colours – here the television does not disappoint and presents a high-quality image.

Some imperfections can be noticed in the brightest areas of the screen, such as in a scene from the film Kingsman (sun in a blue sky). Nevertheless, the final effect should satisfy the vast majority of users.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

TCL C75B has a feature for smoothing tonal transitions, but unfortunately, we cannot praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature wasn’t working at all. It’s hard to say anything positive about it, as in practice it seems completely useless.

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

Blur (native resolution, maximum refresh rate):

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on a smooth, clear image without motion blur.

TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

On the positive side, the presence of a Game Bar feature allows for quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.

Measuring input lag on the LG UR781 television turns out very well, regardless of the signal or resolution. Gamers will surely appreciate the manufacturer's efforts, as gameplay in 4K at 60 Hz with HDR enabled achieves only 13 ms of lag. This is an exceptionally low score that provides smooth and responsive experiences, even in fast-paced online games where every millisecond counts.

The input lag on the TCL C75B is something that truly impresses. With a refresh rate of 144 Hz, the lag is just 9 ms, making the TV's response to our actions on the controller or keyboard practically instantaneous. For 60 Hz, the result is 19 ms – it's not a record low value, but it still falls within a range where the lag is practically unnoticeable during gaming. One could say that the difference is hardly felt, which makes this TV a good choice even for more demanding gamers.

Displaying text in 4K resolution at 60 Hz is exceptionally sharp, with excellent colour reproduction, meaning that even fine details like grey letters are clearly visible, despite the use of a BGR pixel layout. An input lag of 14 ms ensures quick responses, making the television ideal for work. Unfortunately, the employed 60 Hz panel and lack of G-Sync do not meet the needs of gamers using a computer, resulting in a lower rating for gaming. Nonetheless, the television performs well in office tasks and media viewing, which compensates for its use at work.

TCL C75B is quite a good choice for connecting to a computer. With high refresh rates, low input lag, and G-Sync support, the television performs exceptionally well in games – both fast-paced and more demanding ones. The image is smooth, and the response to our actions is quick, which gamers will undoubtedly appreciate.

For office work, the television also holds up well. Text is readable, although on a dark background some imperfections can be noticed – some fonts appear as if they are missing pieces of vertical lines. This may be distracting if we work a lot with documents or text editing. However, if the computer is mainly used for gaming or watching movies, TCL C75B will easily serve its purpose as a monitor. It’s a versatile device that can handle most applications.

Viewing angles

3.5/10

2.7/10

Brightness drop at an angle of 45 degrees
70%
86%

A characteristic feature of VA panels is the noticeable drop in image quality at angles. In the case of this model, when viewed at a 45-degree angle, brightness decreases by as much as 70%, which significantly affects the depth of black and overall image quality. The LG UR781 televisions with VA panels do have better contrast when viewed head-on, but their viewing angles are limited compared to other technologies, such as IPS.

The viewing angles on the TCL C75B are, unfortunately, very poor. This is a typical compromise with VA panels – better blacks at the expense of off-angle visibility. The picture quickly loses quality when viewed from the side, which is the complete opposite of what IPS panel televisions offer. If we plan to watch the TV mainly head-on, this won't be a big problem. However, with a larger number of viewers sitting at different angles, the picture quality may disappoint.

Thanks to its satin finish, it handles glare well during daytime viewing, making reflections less bothersome. However, due to its low brightness in SDR mode, which is only 231 nits, it may struggle to display images clearly in brighter rooms, especially on sunny days. Watching in such conditions may result in poorer visibility and reduced image clarity.

TCL C75B performs okay during the day. The satin display somewhat limits reflections, but it's not an ideal solution. Brightness is also an issue – 350 cd/m² is simply not enough for comfortable viewing in a brightly sunlit room.

In less extreme conditions, for example, in a moderately lit room, the TV does alright. However, if the sun starts streaming directly onto the screen in summer, watching can become tiring. It's worth keeping this in mind when choosing this model.

WebOS in LG UR781 televisions is a modern, intuitive system that provides easy access to popular streaming apps like Netflix and YouTube, among others. It features a simple interface and supports functions such as Screen Mirroring, AirPlay, and Bluetooth. The system supports the connection of external devices like keyboards and headphones, offering rich personalisation options and advanced multimedia features. Unfortunately, the base model of the LG does not come with a Magic remote (on-screen cursor), which is a shame! It's also worth noting that in the case of this model, WebOS was not particularly responsive and can be a bit annoying.

TCL C75B is a television that primarily relies on the Google TV system. The platform offers access to most popular apps, such as Netflix, YouTube, and Prime Video, making it great for watching content from the internet. However, it's worth mentioning that the system can sometimes stutter slightly, which may be noticeable during everyday use.

In terms of smart features, the C75B performs well. Voice control with the help of the built-in assistant works smoothly, and thanks to AirPlay and Miracast, we can easily transfer content from our phone or laptop. Bluetooth allows for effortless connection of headphones, controllers, or other devices.

However, anyone expecting classic television features may be disappointed. There is no option to record programmes on a USB drive or a picture-in-picture (PiP) feature. TCL has been skipping such features for some time, which may not appeal to users who mainly rely on traditional television.

Television LG UR781 will play most files and video codecs, and when subtitles are added to the film, you can even change the colour or size of the font. The biggest downside is the lack of support for less popular photo formats.

The built-in media player in TCL C75B works really well. It handles most popular image and audio formats with ease. Although there are some shortcomings in the support of certain formats, thanks to Google TV, you can easily install an alternative player that will solve this issue.

Although the TV offers a certain hint of bass, the overall sound quality is average. The television does not support most advanced surround sound codecs, which limits its capabilities in fully reproducing audio effects. The only support for surround sound is the ability to stream audio to an external device, such as a soundbar, using Dolby Digital Plus.

The sound on the TCL C75B is really pleasant, especially at lower volume levels. The bass is noticeable and complements the sound well, but only up to about 40% volume. At higher settings, problems start to arise – the bass causes unpleasant vibrations, and the speakers begin to crackle. If we plan to use higher volume levels more frequently, it’s worth considering purchasing a soundbar, as the built-in speakers may not meet more demanding situations.
