LG UR781 vs LG QNED80A6A (VA)

In HDR mode, the LG UR781 falls short of the brightness expected for high-quality HDR experiences. Tests across multiple panels revealed a brightness of around 200 nits, which aligns more closely with SDR standards. As a result, HDR effects lack the desired impact, with bright and dynamic scenes appearing less striking than they should.

The television also exhibits limitations in colour reproduction under HDR settings. The colours may not appear as intense or rich as those on models that handle wide colour gamuts more effectively, leading to a less vibrant and dynamic image overall. Additionally, the LG UR781 struggles with accurate colour representation in HDR mode, which can result in muted content, particularly during daylight viewing when the image can lose its intensity.

Although the dynamic tone mapping feature helps optimise the image, it does not overcome these shortcomings. For users seeking a truly immersive HDR experience with vivid colours and bright highlights, the LG UR781 may not meet expectations.

Let's talk now about how this TV shines. If you expect dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. That's not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamic range" that flagship products offer. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another key category: colors. Here, the PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. Thanks to this process, the TV offers a significantly wider color palette than classic LCD designs. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even at lower brightness, when watching movies in HDR, the colors will be vivid, deep, and properly saturated. The image is not washed out but lush, which is a significant advantage in this price range.

In Filmmaker Mode, the LG UR781 demonstrates the best factory-calibrated performance but exhibits notable flaws. The primary issue lies in white balance, where the graph indicates a drop in blue levels, resulting in a warmer image with a shift towards yellow tones. This deviation impacts the naturalness of colour reproduction, particularly in scenes with white or neutral backgrounds. The Test Colour Checker confirms that some colours deviate into incorrect shades, leading to a lack of true-to-life representation. This can diminish the realism of film scenes, with certain details appearing in inaccurate colours.

In terms of contrast, the gamma graph reveals a drop to a level of 2.0, below the optimal value of 2.4. This results in darker parts of the image appearing brighter than they should, reducing depth and dynamic range. Additionally, the EOTF curve shows an unnatural spike at the beginning, leading to over-brightness in the brightest areas of the image. This can cause a loss of detail in high-luminance scenes, further impacting the overall image quality.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with a VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV “out of the box” serves us a picture with a clear dominance of red and a deficiency of blue. The overall image is very warm, almost hot. Many users might describe this as a “too cinematic” image, approaching sepia. Additionally, there's the issue of the gamma curve – the TV tends to slightly, artificially brighten scenes (the gamma is too low), causing the picture to lose some of its plasticity. The good news is that these are not flaws of the panel, but merely of the software. As always in our tests, we carried out a professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

After calibration, the LG UR781 demonstrates commendable colour reproduction for SDR content. The calibration effectively improves white balance, yielding natural and balanced tones across various scenes. Gamma adjustments contribute to precise detail representation in shadows and highlights, enhancing overall image clarity. This results in a well-rounded performance for everyday use, with solid colour accuracy and well-balanced imagery in SDR mode.

HDR content, however, reveals the TV's limitations. The lack of support for a wide colour gamut restricts the depth and vibrancy that HDR is capable of. The EOTF curve deviates from the ideal, overemphasising details in bright areas, which introduces inaccuracies in colour representation. Tests using the Colour Checker confirm significant errors in colour reproduction. Additionally, the panel's relatively low brightness exacerbates these issues, diminishing the impact of dynamic range effects and causing colours to appear washed out.

While HDR mode highlights the TV's shortcomings, the improvements after calibration, particularly in SDR performance, are significant. Enhanced white balance and gamma adjustments greatly improve the viewing experience, providing more natural and consistent colour reproduction. Compared to its pre-calibration state, the LG UR781 now offers a much better performance for everyday use, especially in standard dynamic range scenarios.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initially too warm white balance and, most importantly, correct the gamma curve. The TV stopped artificially brightening scenes, which added depth to the image. The biggest improvement is visible in SDR content, meaning when watching regular television, YouTube, or in games without HDR. Here, the QNED80A shows its class – color reproduction errors (DeltaE) dropped below a value of 2. In technical terms, this means that the errors are practically unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Even though we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the TV still "interprets" the image in its own way. This is due to the nature of the edge-lit local dimming used and the fact that LG gives the calibrator a very limited range of control over this parameter. In short: the TV struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is much more accurate and pleasant to the eye than in factory settings, even if it still falls short of studio ideal.

The tonality smoothing function on the LG UR781 yields mixed results. At the "low" level, it neither enhances image quality nor effectively diminishes film grain, making its impact relatively negligible. Increasing the strength of this function can soften gradations and reduce visible banding, but it risks over-softening the image in certain scenes, which may compromise the overall sharpness and detail.

As for image scaling, the LG UR781 struggles to deliver exceptional performance, particularly with lower-resolution content. The TV employs an artificial sharpness enhancement technique that introduces defined contours to create the illusion of sharper images. While this may appeal to users who prefer pronounced, vivid details, others seeking a more natural and authentic look may find this effect distracting or unrealistic. Ultimately, the perception of these enhancements will depend on personal preferences, with some users valuing the added sharpness and others prioritising natural image quality.

In this category, the QNED80A proves to be a real "dark horse." It's a fantastic, affordable television for those who often watch lower quality materials – for example, from traditional cable TV. The processor used here handles upscaling exceptionally well, meaning it enhances low resolution to native 4K. The image after processing is natural, smooth, and most importantly – not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality material. This feature works really effectively, eliminating the annoying "banding" of colors in heavily compressed video. However, we must remain vigilant. Remember that we are not dealing with a top-tier processor known from flagship OLED models. In more challenging scenes, the system may struggle and introduce minor artifacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, as in most cases, the improvement in quality is noticeable to the naked eye.

The LG UR781 television provides decent motion fluidity for movies, primarily due to its "True Motion" feature. This option lets users fine-tune motion smoothing on a scale from 0 to 10, catering to different viewing preferences. Lower settings preserve a traditional cinematic effect with some judder, while higher settings create a smoother, more theatrical image. Although the latter deviates from the cinematic standard, it may appeal to viewers who prioritise seamless visuals.

However, performance declines when handling dynamic sports content and fast-paced games. Its 60Hz panel limits interpolation capabilities, meaning motion smoothness in movies can be improved, but motion blur cannot be effectively reduced. The absence of support for 120Hz and BFI (Black Frame Insertion) technology exacerbates this, causing fast-moving objects to blur. Moreover, the panel's slower response time further reduces sharpness in rapid scenes, which can be a drawback for gamers and sports enthusiasts seeking clear, fluid visuals in high-speed scenarios.

We move on to a matter that may be decisive for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This TV is equipped with a panel that has a native refresh rate of 60Hz. There's no point in hiding it – at this price, we expected more because we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strong suit of this screen. Fortunately, LG has equipped the TV with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother while still looking natural, without the artificial "TV theater" effect.

The LG UR781 provides several features designed to enhance console gaming experiences but comes with notable limitations. On the positive side, it includes the ALLM (Auto Low Latency Mode) feature, which automatically switches the TV to a low-latency mode, optimising response times for gaming and benefiting fast-paced titles. The television also supports HGiG, ensuring HDR games are displayed enhancing the overall gaming experience. Additionally, the Game Bar feature allows gamers to quickly access and adjust settings during gameplay, offering added convenience. However, there are significant drawbacks. The TV lacks VRR (Variable Refresh Rate), which may result in screen tearing or stuttering, particularly during dynamic scenes. It also does not support Dolby Vision for gaming, limiting HDR picture quality in titles that use this format. The 60Hz panel restricts gameplay to 60Hz, excluding smoother experiences available at higher refresh rates like 1080p@120Hz, 1440p@120Hz, or 4K@120Hz. The absence of G-Sync or FreeSync technology reduces compatibility with systems designed to synchronise the frame rate between the console and TV, potentially affecting gameplay fluidity. The LG UR781 is a functional choice for casual gamers who value affordability and features like ALLM and HGiG. However, it falls short for those seeking advanced gaming features such as high refresh rates, VRR, or Dolby Vision gaming.

Since we have established that the QNED80A is a 60Hz panel television, we must say it directly: we will not be playing here at 120 frames per second in any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for "casual" gamers. LG has decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) ranging from 48-60Hz and an automatic game mode ALLM, which quickly reduces input lag upon detecting a console. We manage all of this through a very convenient, purple Game Optimizer menu (Player Panel), which has already become LG's trademark. The manufacturer deserves big credit for consistency regarding HDR. Although the television does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a moderately bright screen, HDR gaming is clear, and details in shadows and highlights are accurately reproduced, rather than "cut off."
