LG UA75006LA (IPS) vs Samsung S90H (WOLED)

It looks even more modest in the version with an IPS panel, where the peak brightness only reaches 250 nits. In practice, this means that a real sense of HDR effect is out of the question, and the materials being viewed resemble regular SDR. Similar to VA panels, the image behaves stably across most test patterns, but in demanding scenes with fine details, the television tends to slightly dim the picture. As a result, blacks appear a bit better, but at the cost of losing detail in bright elements. The absence of additional colour filters is also noticeable here. The UA7500 in the IPS version is neither a QLED nor a PFS LED panel, and the DCI-P3 colour gamut stops at 80%, which means that HDR films lack significant colour depth and appear quite flat.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although it is slightly dimmer compared with the QD-OLED version. That difference is not as pronounced as in last year’s F series, where gaps sometimes reached 500 nits. Here the parameters of both panels are very similar, with differences in peak brightness of only about 100–150 nits. In small-window measurements the S90H with the WOLED panel easily reaches close to 1,500 nits. That headroom lets it phenomenally convey the dynamics of HDR effects — blooms, light reflections and explosions have the right punch, exactly as intended by the studio creators. As with most OLED displays, when a very bright scene fills the entire screen, panel protection systems kick in and brightness naturally falls to around 700 nits. It’s worth stressing that this is still an excellent result on the market, often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, very high-brightness colours don’t achieve quite the same saturation, and the wide-colour volume is slightly more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches almost 99%, meaning that for the vast majority of real film scenes both variants will present an almost identical image. The real gap only appears in rarer, especially demanding productions that use the ultra-wide BT.2020 gamut. Because of the WOLED panel’s construction, coverage of that standard is roughly 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit HDR colours may appear a touch less vivid.

The Filmmaker mode on the LG UA7500 performs better than you might expect from such a budget television, but let’s not get carried away with admiration. The picture is put together quite sensibly and at first glance is not irritating; however, its weaknesses quickly become apparent. This is most noticeable in scenes with bright points – lamps in the background or reflections of light on skin are clearly oversaturated. The faces of characters often appear unnatural, as if they have been "blown out." Additionally, the default gamma setting brightens even the slightest details and causes the picture to lose subtlety in the darker areas. That said, for its price range, the UA7500 in factory mode provides a pretty decent starting point. However, it is clear that without additional adjustment, these issues won't be avoided, which is why – as with other televisions – we decided to see what could be achieved after calibration.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the annoying oversaturation seen in more aggressive profiles. However, as is often the case without full calibration, there is unit-to-unit variation. In our test the white balance was a little deficient in the blue component, so the image leaned slightly towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at around 2.2, which caused a small lift in shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

The biggest improvement we noticed was when calibrating the mode intended for everyday SDR content. We managed to smoothly adjust the white balance in an acceptable manner and tame the issue of excessive brightening of small elements due to the gamma characteristics. As a result, the image gained consistency and a naturalness that was lacking in the factory settings. After such a correction, we can confidently say that for everyday television content, programmes, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation is somewhat different for HDR content. Here, calibration did manage to tame the white balance and slightly improve brightness management, however, the design limitations are immediately apparent. The lack of additional filters that expand the colour palette means that the most vibrant colours appear flat, and the image lacks the intensity one would expect from good HDR. In SDR, the UA7500 performs quite well, but in HDR – despite the corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

After full calibration, you can safely say the S90H in the WOLED version looks almost perfect. In SDR mode colour errors fall to ultra-low levels and Delta E values very rarely exceed 2. That's a phenomenal result, so if perfectly faithful colour reproduction matters to you, it's definitely worth getting it calibrated. The calibrated HDR mode also performs very well, where the white balance was stabilised and previous deviations eliminated. After professional tuning it's really hard to fault anything, because the TV delivers an image with almost exemplary naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the saturation limitation in extremely bright scenes, while the tuning potential and colour fidelity are at the highest level.

The version with the IPS panel performed noticeably worse here. Image scaling was uneven – this was especially evident in lower quality materials, where edges became jagged and the image looked less detailed. At times, there was also a sense of slight blurriness, which took away sharpness and made the overall picture seem less refined than in the VA version. The tonal smoothing function turned out to be a rescue. On medium settings, it worked quite well – it did not ruin the image with excessive softening, while also smoothing out colours in such a way that everyday content gained consistency. The difference was particularly noticeable with TV programs or streaming materials of poorer compression quality, where the television with the function enabled presented itself much better. This is one of those additions that are worth keeping active, as they significantly improve the reception of everyday materials.

When it comes to banding reduction itself, Samsung has kept the same solutions known from last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that’s somewhat more prone to banding. However, it’s important to remember it acts aggressively. This mechanism, aside from the artefacts themselves, can remove fine film grain and subtly soften detail. Ultimately it’s a trade-off, but if you want perfectly faithful image reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so upscaling quality was almost identical. The chip sharpens lower-resolution material very well, pulling a satisfying level of detail out of it. However, Samsung still hasn’t solved the old overscan problem. For some older recordings or archival footage the edges of the image can be slightly cropped. It’s a minor drawback, but it’s a shame the manufacturer still hasn’t fixed it.

LG UA7500 is a television with a 60 Hz panel, so it's hard to expect any excitement in this category. It's more of a screen intended for daily content or an evening movie session rather than for following fast-paced sports events or playing action games. It’s clear that the manufacturer designed this model specifically for that audience – and it performs well in that regard. We have the TruMotion function available, which is a motion smoother. It’s simple, has only one slider, but can make a noticeable difference. At the lower range, the image looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasurable to the eye.

When it comes to motion handling the S90H is simply excellent. This year's panel offers its refresh rate boosted to 165 Hz, although in practice the benefit will mainly be for gamers connecting a powerful PC. For movies, TV series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, the OLED panel's lightning-fast response time does the job. Motion is clean, and the ghosting or smearing seen on LCDs simply doesn't occur here.

LG UA7500 is a TV that can be confidently recommended to "casual" gamers. While it doesn’t feature a 120 Hz panel or HDMI 2.1 ports, making full use of the potential of modern consoles isn’t something we can expect. However, the manufacturer has included several additions that can enhance the gaming experience. Notably, there's the Game Bar – a very nicely designed panel that allows quick access to and changes of the most important settings. From this panel, we have access to the ALLM mode (automatic switching to game mode), as well as frame synchronization, or VRR. The range of VRR is limited – it works from 48 to 60 Hz – but the mere presence of this feature in such an affordable TV leaves a positive impression.

Additionally, it also supports HGiG, which is a HDR calibration mode for games. It sounds good, but from our testing experience, we know that for the UA7500 this option doesn’t make much sense. The TV doesn't perform well with HDR, so paradoxically, we achieved better results with this mode turned off. This is another signal that the UA7500 is more of a screen for occasional gamers who value simplicity and convenience rather than for those looking for the full experience from the latest consoles.

Gamers should feel right at home with the S90H, because Samsung has left few reasons to complain in this area. The TV has four HDMI 2.1 ports, each supporting VRR, ALLM and high refresh rates. There's also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG. In last year's models it could cause issues when used with a console, but on the S90H it now works as it should. What really stands out against the competition is Game Motion Plus. It's a specialised motion-smoothing mode for games that works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother and latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That's important, because on many TVs enabling a similar smoothing feature causes such a big increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There's still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be the more useful feature.
