LG UR781 vs Blaupunkt UGC5500S

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.

We won’t beat around the bush here – if you’re looking for a TV strictly for cinematic HDR experiences, then you’ve come to the wrong place. Unfortunately, the Blaupunkt UGC5500S is not a machine built for such challenges. This is primarily due to its very low brightness, which we measured during our tests. A result of around 250 nits on movie screens speaks for itself. It’s simply too little to even consider any real HDR effect. To be honest, everything displayed in this format can confidently be seen as a somewhat “enhanced” SDR mode. We expected this, as practically every device in this price range falls short in this area, but we feel it’s our duty to warn you. Manufacturers love to brag about HDR compatibility on the boxes, but in reality, this format simply doesn’t exist here – it lacks the “fuel” in the form of brightness.

The situation is further complicated for Blaupunkt, as we’re dealing with a panel that has very basic coverage of the DCI-P3 colour gamut, reaching only about 80%. You won’t find any advanced coatings to expand these capabilities (like quantum dots), which means scenes that are supposed to burst with richly saturated colours appear simply underwhelming on this screen. Therefore, we have a particular piece of advice for you: don’t force HDR mode on this model. If you have the option in the streaming app settings – just turn it off. By sticking to the classic SDR mode, you’ll be sure that the TV won’t try to “enhance” something that it can’t handle hardware-wise.

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.

We also took a close look at how Blaupunkt handles colours in movie mode, and here the matter is, to put it simply, twofold. We must once again clearly separate what we see in the standard SDR format from what happens when HDR is switched on, as they are two completely different worlds. Let's start with the better side of the coin. If you're planning to watch traditional TV, YouTube, or older films on this television, you can count on really well-tuned colours. In our test sample, the white balance in movie mode performed exceptionally well, which honestly surprised us. Of course, to avoid being too rosy, we noticed some drawbacks. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest areas. Additionally, there is quite a strong, at times overly aggressive, red saturation, which resulted in visible errors in reproducing certain shades. Despite this, overall, the image in SDR is simply solid and watchable without a grimace on your face. Unfortunately, the magic fades when we re-enter the world of HDR. Here, Blaupunkt behaves as if we suddenly switched it to store mode, and in its worst rendition. The excess blue in the white balance is so significant that it’s glaring, ruining any realism in the scene. Furthermore, the television interprets brightness very loosely, which, upon analysing the EOTF curve, clearly showed that for most of the time, colours simply appear washed out and lacking depth. This is also perfectly evident in the colour errors that become apparent in this mode. Once again, we are left with the same conclusion: Blaupunkt in SDR mode looks significantly better and more natural than in HDR, which seems to be forcefully added without proper refinement.

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.

It may sound like a joke – pulling out professional measuring equipment for a TV that costs around a thousand złoty / 250 dollars, but we wouldn’t be ourselves if we didn’t check it. The question is: does such cheap gear give us any leeway in terms of calibration? To your surprise, the answer is: yes, absolutely. In the Blaupunkt UGC5500S menu, we found surprisingly many options that allowed us to effectively work on the picture. These aren't just empty sliders; these are concrete tools that enabled us to make use of our measurement sensors and software. In SDR mode, the effects were visible to the naked eye. We successfully eliminated the problem we mentioned earlier – that excessive, almost artificial saturation of reds. We also fixed the issue with the incorrect dimming of the brightest parts of the image. After calibration, the picture in standard format became significantly more balanced and simply correct. When it comes to HDR, the situation was more complicated again. While we managed to “tame” that aggressive blue tint in the white balance, it was clear that we were fighting a bit of a losing battle. Even after changing the settings, the TV still tried to interfere with the picture in its own way, as if the electronics knew better than we did how the scene should look. To top it off, there's the hardware barrier that no slider can overcome – colours in HDR still remain undersaturated. This simply results from the quality of the panel itself; it physically cannot produce the most vivid colours. To summarise this point: if any of you ask whether it’s possible to calibrate a TV for “a grand”, we respond with complete conviction: it is possible.

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.

If you're hoping that the processor in this model will magically "fix" the poor quality signal from your cable TV or old movies from YouTube, we must disappoint you. The capabilities of this television end at absolutely basic upscaling, which is simply stretching the image to a higher resolution. It does this correctly in that the image is not blurry, but there is no mention of any intelligent sharpening or adding details. Worse still, Blaupunkt is completely devoid of any functions to reduce unwanted tonal transitions. If the material being viewed shows what is known as banding (ugly "steps" instead of a smooth transition of colours, e.g., in the sky), this television will display them in all their glory. Additionally, the television has a tendency to slightly crop the edges of the image. Instead of displaying 100% of what the source sends, Blaupunkt slightly zooms in on the frame, causing us to lose details that are at the very edges of the screen. In summary: in the category of digital "enhancement" of the image, Blaupunkt simply performs poorly. We receive a raw, unprocessed signal, with all its flaws.

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.

When it comes to motion fluidity, Blaupunkt has nothing to defend itself with. A 60 Hz panel at this price is standard, so none of us expected a perfectly sharp image in fast action scenes or during a match. However, the biggest drawback of this model is that you won’t find any digital motion smoothers in the menu. The manufacturer hasn’t given us any room for manoeuvre – nothing can be smoothed out or the image adjusted to our personal preferences. The picture is always "raw" and we receive it exactly as it is transmitted by the source. For fans of cinematic "jumping" images, this might be good, but the rest simply has to get used to the lack of any motion enhancement.

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.

When it comes to gaming on the Blaupunkt, we weren’t expecting miracles and indeed – the list of features isn’t very long. However, there are two interesting points worth mentioning, as they might be significant for some of you at this price. The first advantage is that the TV quite smoothly detects the connected console. Thanks to the ALLM (Auto Low Latency Mode) feature, the device knows when you start gaming and automatically switches to low latency mode. This is convenient because you don’t have to fiddle with settings every time to ensure input lag doesn’t spoil the fun. The second point is a real curiosity that surprised us. Despite it being a 60 Hz panel, the Blaupunkt can display a 120 Hz image at Full HD resolution. Sure, we lose 4K details, but for those playing more dynamic, online shooters where smoothness is more important than resolution, this is a really nice and unexpected addition in such an affordable device. Other than these two points, you won’t find anything more here. There are no advanced smoothness enhancement systems for gamers or extensive gaming menu bars. It’s a simple screen for occasional gaming.
