LG UR781 vs Haier Q80FUX

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 similar to levels typical for SDR, causing HDR effects to be insufficiently pronounced, and the image may appear 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 manage better with a wide colour gamut. In practice, this can make the image less vibrant and dynamic, and HDR effects will not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurately reproducing colours in HDR mode, resulting in content that may look less vivid.

Alright, let’s move on to the topic that stirs up so much discussion, namely the capabilities of the television in HDR mode. Let’s state it clearly right away: the Haier Q80FUX is certainly not a brightness demon. The panel of this receiver can generate about 350 nits at peak, which in today’s terms is the absolute minimum to even talk about the presence of High Dynamic Range (HDR). On the positive side, this power is at least stable – regardless of which test pattern or film scene we used, the measurements consistently oscillated in the range of 300-350 nits. These are therefore results that are at best sufficient, definitely far from the dazzling display of capabilities we are accustomed to with more expensive models. Fortunately, there is one aspect in which the Q80FUX compensates for these shortcomings and does so impressively. After all, we are talking about a QLED television (more precisely PFS LED), which means that thanks to the quantum dot filter applied to the panel, it can generate really juicy, vibrant colours. These are not empty promises – a DCI-P3 colour gamut coverage of nearly 95% is an impressive result and directly translates into colours that are very pleasant to the eye and saturated.

The colour reproduction in LG UR781 in Filmmaker Mode, which although is the best mode available from the factory settings, is not without its flaws. Firstly, the issue is white balance, where the graph shows dips in blue colour levels. This phenomenon results in a shift of hues towards yellow tones, causing the image to appear warmer than it should. Such deviation means that the colours on the screen are not naturally reproduced, which can be particularly noticeable in scenes with a white or neutral background. This can be confirmed by the Test Color Checker, which showed that some colours "shift" into other shades, meaning that the LG UR781 television does not display colours in accordance with reality. This distortion can affect the visual experience, making movie scenes seem less realistic, and details might be displayed in inappropriate colours, negatively impacting the overall image quality.

In terms of contrast, the analysis of the gamma graph revealed drops to a level of 2.0, whereas the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in certain scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was observed at the beginning. This phenomenon can result in excessive brightness boost in the brightest parts of the image, leading to loss of detail in very bright scenes.

Factory settings for movie mode are rarely perfect, but in the case of the Q80FUX, we were confronted with a noticeable imbalance. In SDR content, the image was decidedly too warm, a result of excessive red in the white balance, giving the whole a slightly sepia tone. Ironically, in HDR materials, the television fell into the opposite extreme – an excess of blue caused an unnatural, cold effect in perception. However, it was not the capricious white balance that was the biggest problem with this television. The real culprit, responsible for the aforementioned issues, was hiding deeper. It turned out that the Q80FUX has completely miscalibrated gamma values and, crucial for HDR, a poorly executed EOTF curve. It was these erroneous factory settings that caused persistent clipping of the brightest parts of the image, overlaying them with that characteristic milky filter. Thus, we found the source of the problem. This state of affairs led to general, significant colour errors, which were easy to catch even for an untrained eye. Like every television we tested, we decided to calibrate this model as well, and the results of these adjustments can be found in the next paragraph.

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

However, the situation is worse for HDR content. The LG UR781 television does not support a wide colour gamut, which limits the depth and richness of colours that HDR can offer. The EOTF curve deviates from the ideal, resulting in excessive highlighting of details in the bright parts of the image. Unfortunately, this 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 the quality of HDR images, causing dynamic range effects to be not fully realised, and colours to appear washed out.

Despite some shortcomings in HDR mode, the television has improved significantly after calibration, especially in SDR content. The improvement in white balance and gamma has greatly enhanced image quality, providing a more natural and cohesive colour representation. Compared to its state before calibration, the difference is clear, and the LG UR781 television now offers better performance in everyday use, particularly in the standard dynamic range.

The results of our calibration procedures must, regrettably, be acknowledged as twofold. Generally speaking, the picture is undeniably better than before the corrections; however, the biggest winner of this process turned out to be SDR content. It is precisely there, after correcting the gamma and white balance graphs, that we achieved results that can confidently be called very good. After adjustment, the Q80FUX truly shines in standard dynamics, showing only slight errors in the most difficult skin tone reproductions. Unfortunately, the weakest link remains HDR content. Here lies the paradox: despite having calibrated the white balance to nearly perfection, the overall colour errors still remain at quite a high level. The reason is that the television continues to interpret static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate image burn-out effect, which inevitably leads to significant distortions. Although we have successfully eliminated the factory excess of blue, it is precisely due to this interference of electronics that the screen still tends to stray into somewhat overly cold tones. That is just how this television is.

Now let’s address the function of smoothing tonal transitions and its impact on overall image quality. As illustrated in the photo on the left, this function performs exceptionally mediocrely; we selected the "low" level, which does not improve quality but also does not blur the film grain. There is the option to increase the power of this function, which would soften the gradation; however, one must reckon with the fact that the image will be too softened in some scenes.

On the other hand, regarding image scaling, the television does not perform exceptionally, which can be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpness boost, which makes the image appear sharper, but this primarily results from the overlay of artificial contours. For some users, this can be an advantage, as they prefer more vivid, accentuated details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural look to the image.

If there is one area where Haier clearly shows it still has a long way to go compared to the market leaders, it is digital image processing. The upscaling, well... is just alright. And that’s really about all that can be said about it. It does what is expected of it: it ensures that lower resolution signals do not scare us with harsh pixelation on the screen and do not look like a forcibly enlarged postage stamp. However, it is far from the finesse and “intelligent” sharpening that more experienced players in this market have developed over the years. The biggest shortcoming of the Q80FUX software is the almost complete lack of any additional "cleaning" and smoothing functions for the image. The receiver does not offer any noise reduction or gradient improvement mechanisms. This means that with older or heavily compressed materials, we simply have to come to terms with the fact that any imperfections in tonal transitions or blending of colours, which we mentioned earlier, will continually accompany us during the viewing.

The LG UR781 television offers quite decent smoothness for films, thanks to the "True Motion" option, which allows users to adjust the level of motion smoothing on a scale from 0 to 10. The user can choose whether they want to preserve a more traditional, cinematic effect with subtle judder (lower settings) or prefer a smoother, theatrical image that, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and games, the LG UR781 television performs worse. The television has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, it can improve fluidity in films but cannot reduce motion blur. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that quick movements of objects become blurred, and the response time of the panel is too long, negatively affecting clarity in fast scenes. As a result, the television may not meet the expectations of gamers and sports fans who are looking for a smooth, clear image without motion blur.

The issue of motion fluidity and blurring is largely predetermined by the use of a 60-hertz panel, which naturally makes it difficult to recommend this receiver to enthusiasts of very dynamic content. Fortunately, in the Q80FUX, we find a few options (although, as we shall see shortly, in reality only one) that are supposed to improve the experience with older film productions. There is a "De-Judder" slider available, which actually controls the smoothness of the image and allows us to adjust it to our preferences: from raw, cinematic frame rates to a more theatrical, smoothed presentation. However, a true surprise awaits us just beside it in the menu. There is also a second slider, supposedly dedicated to removing blur – a feature we typically encounter in 120Hz panels to combat motion blur in sports. However, as we expected, recalling memories from the tests of the K85F model, this slider here is merely a façade. Its adjustment does absolutely nothing to the image and it simply appears to be an oversight by the product engineers who left a non-functional option in the software for this type of panel.

While gaming on the console, the television LG UR781 offers several important features that can affect the gaming experience, but it also has some limitations. A positive aspect is the presence of ALLM (Auto Low Latency Mode), which automatically optimises picture settings by switching the television LG UR781 into low latency mode, which is beneficial for gamers. The television also supports proper implementation of HGiG, meaning HDR games look as intended by the developers.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which may result in poorer fluidity of gameplay, particularly in more dynamic games. It also does not support Dolby Vision mode for games, which limits the HDR picture quality in games using this format. The television has a panel with a frequency of 60hz, which means it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant drawback for gamers expecting smoother gameplay at higher resolutions. It also lacks support for G-Sync technology, which limits image synchronisation in games.

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

Stepping into the realm of gaming, the Haier Q80FUX proves to be quite a decent companion for the "casual gamer". Onboard, we find highly desired features such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). However, the biggest surprise is something else altogether. Although we are not dealing with a 4K@120Hz panel here, the television is capable of accepting and displaying a 120Hz signal at a lower resolution (Full HD). This is a very useful feature that allows for a conscious switch of the console to a lower resolution mode in exchange for significantly higher smoothness, which is a compromise entirely acceptable in the gaming world.

We won’t particularly complain about the lack of extras like the "Game Bar", as it's merely a nice addition. The most concerning issues arise when we delve into the world of HDR in gaming. Due to the television constantly adapting the signal "in its own way", setting the brightness on the console according to the HGIG standard is nearly impossible to achieve as per instructions. Worse still, in the Dolby Vision mode for gaming, the input lag increases to around 50 ms, which is a value high enough to render this mode practically unusable. However, in general, we would not recommend gaming on this television in HDR mode, so these are not such grave shortcomings. What is most pleasing is the presence of 120Hz in Full HD, which makes the Q80FUX a rather nice television for the occasional gamer.
