LG OLED G4 vs Blaupunkt UGC5500S

The LG G4 excels in delivering an incredibly vivid HDR experience, positioning it as one of the best models in its class. Equipped with second-generation Micro Lens Array (MLA) technology, it achieves a remarkable peak brightness of 1474 nits in real-world scenes. While it may not match Mini LED-backlit LCD TVs in full-screen white scenes, the overall performance is outstanding. The fine details in HDR content shine brightly, a distinct advantage of OLED technology over non-OLED displays. With this impressive brightness and wide DCI-P3 colour gamut coverage, HDR content is brought to life with unmatched engagement and immersion.

Here, we won't beat around the bush either – if you're looking for a TV strictly for cinematic HDR experiences, you've come to the wrong address. The Blaupunkt UGC5500S unfortunately is not a machine designed 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 film screens speaks for itself. It's simply too little to even talk about any real HDR effect. To be honest, everything displayed here in this format can best be considered a slightly "boosted" SDR mode. We expected this because practically every device in this price range fails in this regard, but we feel obligated to warn you. Manufacturers love to boast about HDR compatibility stickers on the boxes, but in reality, this format simply doesn't exist here – it lacks the "fuel" of brightness.

The situation is made all the more difficult for Blaupunkt because we have a panel with a very basic DCI-P3 color gamut coverage of just around 80%. You won't find any advanced coatings that enhance these capabilities (like quantum dots), making scenes that are supposed to burst with richly saturated colors appear simply desaturated on this screen. Therefore, we have a concrete piece of advice for you: do not push the HDR mode on this model. If you have the option in the streaming app settings – just turn it off. Sticking with the classic SDR mode will ensure that the TV won't try to "enhance" something that it can't handle hardware-wise.

Before calibration, the "Filmmaker" mode on the TV had a noticeable red and green colour dominance, resulting in a warm-yellow hue across both SDR and HDR content. This warm tone, typical of modes like "Cinema" and "Filmmaker," led to a yellowish cast that was evident when switching from the "Standard" mode.

Looking at the brightness characteristics, the Gamma chart showed decent performance for mid-tones and bright whites, but it struggled with the darkest details, which tended to merge into a black blob. HDR content, as represented by the EOTF curve chart, displayed a drop in contrast due to excessive brightness, which overshadowed fine details and negatively affected the overall image quality. Additionally, the "ColourChecker" chart revealed that colours were under-saturated, contributing to a less accurate and vibrant visual experience.

This provided a good foundation to build on, but calibration was needed to bring out the full potential of the "Filmmaker" mode and address these issues.

We also took a close look at how Blaupunkt handles colors in movie mode, and here the situation is, to put it briefly, twofold. We must clearly separate what we see in the standard SDR format from what happens when HDR is turned on, as these are two completely different worlds. Let’s start with the better side of the coin. If you plan to watch classic television, YouTube, or older movies on this TV, you can count on really well-tuned colors. In our test sample, the white balance in movie mode was exceptionally accurate, which honestly surprised us. Of course, to not make it too rosy, we noticed some flaws. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest parts. Additionally, there is quite strong, at times too aggressive, red saturation, which resulted in noticeable errors in reproducing certain shades. Nevertheless, in general terms, 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 form. The excess blue in the white balance is so overwhelming that it literally clashes with the eyes, ruining any realism of the scene. Furthermore, the TV interprets brightness very loosely, which, when analyzing the EOTF curve, clearly showed that for most of the time the colors appear simply washed out and lacking depth. This is, by the way, perfectly visible in the color errors that become evident 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 feels forced and not properly refined.

The manufacturer has been offering extensive support for the calibration process in its LG televisions for many years. Therefore, we used 2- and 20-point grayscale adjustments along with an advanced CMS (Colour Management System) to optimise the display. As shown, the calibration procedure greatly improved each parameter. The results included studio-quality colour reproduction, enhanced detail in dark areas, corrected brightness characteristics, and accurate colour saturation. This led to a near-perfect match with the reference image—the one the film director saw on the preview monitor. It’s also worth mentioning that LG G4 televisions are unique in offering even deeper image adjustments through 3D LUT matrices, a feature primarily suited for post-production or graphics studios.

It may sound like a joke – pulling out professional measurement equipment for a television costing around a thousand zlotys / 250 dollars – but we wouldn't be ourselves if we didn't check it out. The question is: does such cheap equipment give us any room for calibration? To your surprise, the answer is yes, and absolutely so. In the Blaupunkt UGC5500S menu, we found surprisingly many options that allowed us to really work on the picture. These are not just empty sliders; they are concrete tools that enabled us to make use of our measurement sensors and software. In SDR mode, the effects were noticeable to the naked eye. We successfully eliminated the issue we mentioned earlier – that excessive, almost artificial saturation of reds. We also fixed the problem of incorrect dimming of the brightest parts of the image. After calibration, the standard format picture became much more balanced and simply correct. As for HDR, the situation was again more complicated. Although we managed to "tame" that aggressive blue tint in the white balance, it was evident that we were fighting a bit in vain. Even after changing the settings, the television still tried to intervene in the image in its own way, as if the electronics knew better than we did how the scene should look. Additionally, there's a hardware barrier that no slider can overcome – colors in HDR still remain unsaturated. This simply results from the quality of the panel itself; it physically cannot produce the most vibrant colors. To summarize this point: if any of you ask whether it’s possible to calibrate a television for "a thousand," we respond with full conviction: it is possible.

The LG G4 does not perform well with materials rich in tonal transitions, leading to a pronounced posterization effect. However, the manufacturer has included a smoothing system called "Gentle Gradation," with three levels: Low, Medium, and High. These settings are effective at smoothing bright colours, though less so for darker tones. It is recommended to use the Low setting, as the higher levels can distort the director's intentions by removing film grain.

When it comes to upscaling lower-quality material, the television's performance is quite good, delivering a sharp and clear image. However, attention should be paid to the jagged edges of fine details and the occasional halo effect around figures. This occurs due to the sharpening imposed by the LG G4, even when the lowest setting is selected (0). This is a noticeable change from the LG G3, which did not apply such strong sharpening, even at setting 0.

If you expect that the processor in this model will magically "fix" the poor quality signal from cable TV or old films from YouTube, we must disappoint you. The capabilities of this television end with 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 talk of any intelligent sharpening or adding details. Worse still, Blaupunkt is completely devoid of any functions that reduce unwanted tonal transitions. If the material being viewed has so-called banding (ugly "steps" instead of a smooth transition of colors, e.g., in the sky), this television will display them in all their glory. Additionally, the television tends to slightly crop the edges of the image. Instead of displaying 100% of what the source sends, Blaupunkt slightly enlarges the frame, causing us to lose details located 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 G4 offers a maximum refresh rate of 144 Hz, achievable when connected to a powerful PC. For most users, however, the TV operates at a maximum of 120 Hz, ideal for watching sports or other content with fast motion. To improve image fluidity, the television includes the "TrueMotion" motion smoothing system, which features two separate sliders: De-Blur (for the sharpness of moving images) and De-Judder (for judder reduction). These sliders allow users to adjust the level of smoothing between 0 and 10, ensuring everyone can find the ideal setting.

With a response time of 0.78 ms, the LG G4 delivers exceptionally clear images, outperforming LCD televisions, which can have much slower response times. This results in no trailing blur behind moving objects, as shown in the "UFO Test." The TV also provides precise control over motion smoothing, which is especially beneficial during fast-paced video game sequences. Thanks to OLED technology, the G4 eliminates ghosting, ensuring a crisp and clear image even during the most dynamic sports or action scenes.

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 during fast action scenes or while watching a game. However, the biggest drawback of this model is that you won't find any digital smoothers in the menu. The manufacturer did not give us any room to maneuver – there's no way to smooth anything out or adjust the image to our preferences. The image is always "raw" and we receive it exactly as the source transmits it. For fans of cinematic "motion jump," this might be fine, but everyone else just has to get used to the absence of any motion support.

The LG G4 TV supports all the features encompassed by the HDMI 2.1 standard, making it a gaming powerhouse. During testing, every feature activated seamlessly, ensuring a smooth experience for both console gamers and PC users. Notably, the HGIG mode (HDR Gaming Interest Group) is implemented correctly, allowing games mastered to brightness levels higher than the TV’s maximum luminance to map tones accurately, preserving the game’s original visual integrity.

A notable highlight is the dedicated GameBar, which can be accessed at any time to quickly check or adjust game settings. More importantly, enabling VRR (Variable Refresh Rate) does not compromise contrast—a common issue in TVs with local dimming or Mini LED backlighting. This is thanks to the OLED panel’s self-emissive pixels, which maintain consistent contrast. However, a slight grey flicker may appear when VRR is enabled, though this is standard across OLEDs.

In summary, the LG G4, like most OLED TVs, is ideal for gaming and online competitions. Its HDMI 2.1 ports offer a full 48 Gbps bandwidth, supporting features such as VRR, ALLM (Auto Low Latency Mode), G-Sync, FreeSync, and HDR Dolby Vision gameplay, ensuring an exceptional gaming experience.

When it comes to gaming on the Blaupunkt, we didn’t expect miracles and indeed – the list of features is not very long. However, there are two interesting points worth mentioning, as they may be significant for some of you at this price. The first advantage is that the TV quite efficiently detects the connected console. Thanks to the ALLM (Auto Low Latency Mode) feature, the device automatically knows when you start gaming and switches to low latency mode. This is convenient because you don’t have to fiddle with the settings every time to prevent input lag from ruining the fun. The second point is a real curiosity that surprised us. Even though it’s a 60 Hz panel, the Blaupunkt can display images at 120 Hz at Full HD resolution. Sure, we lose 4K details then, but for those playing more dynamic, online shooters where fluidity is more important than resolution, it’s a really nice and unexpected addition in such an inexpensive piece of equipment. Besides these two points, however, you won’t find anything else here. There are no advanced systems for improving fluidity for gamers or extensive gaming menu bars. It’s a simple screen for occasional gaming.
