Haier M90E vs Samsung S90H (WOLED)

Haier M90E is a television that does not lack brightness. In most movie scenes, peak luminance exceeds 1000 nits, which gives the image a clear "kick" and high dynamics. In typical, bright HDR materials, this looks really good. However, one must take into account the previously mentioned dimming algorithm. In scenes that are not evenly flooded with light – for instance, when displaying individual stars in a black sky – high brightness underscores the imperfections of zone control. Instead of a precise light point, we often see a distinct halo effect around bright objects. Despite these shortcomings, the overall image presentation can be pleasing, largely thanks to color reproduction. The manufacturer applied a PFS phosphor coating, allowing for wide coverage of the color palette. In our measurements, the coverage of the DCI-P3 space was a solid 95%.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price class, although it is slightly dimmer compared to the QD-OLED version. The difference is not as pronounced as in last year’s F series, where gaps could reach as much as 500 nits. Here the specs of both panels are very close, and differences in peak brightness are only about 100–150 nits. In small-area measurements, the S90H on the WOLED panel easily reaches levels close to 1500 nits. That headroom lets it portray HDR dynamics phenomenally—specular highlights, reflections or explosions have the right punch, just as the creators intended in the post-production studio. As with most OLED displays, when a very bright scene fills the entire screen, the protection systems that safeguard the panel 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.

Color gamut coverage

The biggest difference between the two S90H variants lies in color reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, colors at very high brightness don’t achieve quite the same intensity, and the volume of the wide color gamut is somewhat 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 nearly 99%, which means that in the vast majority of real film scenes both variants will deliver almost identical images. The true gap only appears in rarer, particularly demanding productions that use the ultra-wide BT.2020 gamut. Due to the WOLED panel’s design, coverage of that standard is about 15% lower compared to the S90HAT with a QD-OLED panel, so the brightest, heavily illuminated HDR colors may appear a bit less vivid.

For the measurements, we chose the Film mode, which should ideally offer an image closest to the creators' intentions. Unfortunately, in the case of the M90E, its characteristics – besides the reduced brightness – do not differ much from the Dynamic mode. Both in SDR and HDR content, the image is clearly tinged with a cool blue hue. The white balance is heavily skewed towards blue, reminiscent of typical aggressive "store" settings. This results in an unnatural representation of skin tones and makes the image straining on the eyes during longer viewing sessions. The way brightness is managed also negatively affects color fidelity. The television struggles to maintain proper levels – small details are often too dim, while larger, bright areas of the image tend to get blown out. These deviations in the brightness curve, combined with the cool white balance, lead to very significant color reproduction errors (DeltaE) in the factory settings.

In Filmmaker mode, which we strongly recommend enabling right out of the box, the S90H offers very good factory color tuning. Colors are natural and faithful to the filmmakers' intent, without the intrusive oversaturation found in more aggressive profiles. However, as is usually the case without full calibration, there can be unit-to-unit variation. In our test the white balance lacked a bit of the blue component, causing the image to lean slightly toward warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve ran slightly low, around 2.2, which resulted in a slight boost to shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

Haier M90E clearly benefits from professional calibration, especially for SDR content. The TV menu offers a sufficient number of tools to effectively correct factory errors. We managed to "tame" the white balance and eliminate the dominant blue tint. We also adjusted, albeit to a lesser extent, the brightness curve (gamma), which allowed us to recover some details in the shadows that were too heavily muted from the factory. The end result for SDR is a picture that is definitely more natural and pleasant to watch. In the case of HDR mode, the success is only partial. Although it was possible to improve the white balance here as well, the color reproduction errors (Color Checker) remained at a high level. Analysis of the EOTF curve (responsible for brightness in HDR) points to the root of the problem: the TV imposes its own interpretation of the signal and does not provide tools to modify this curve. The source of the high errors is not the calibration itself, but the specifics of the device – aggressive and imprecise zone dimming interferes with measurements and is "stiffly" embedded in the characteristics of this model.

After full calibration it can safely be said that the S90H in the WOLED version looks almost perfect. In SDR mode color reproduction errors drop to ultra-low levels, and Delta E values very rarely exceed 2. That's a phenomenal result, so if you care about perfectly faithful color reproduction it's definitely worth considering calibration. The calibrated HDR mode also performs very well, in which the white balance was stabilized and earlier deviations eliminated. After professional tuning it's really hard to find anything to criticize, because the TV delivers an image with almost exemplary naturalness and dimensionality. The slightly lower rating in this category compared with the QD-OLED variant is solely due to the previously described saturation limitation in extremely bright scenes; the tuning options and color fidelity themselves are at the highest level.

The evaluation of the image processor must be divided into two separate aspects, as the Haier M90E behaves inconsistently in this regard. The first issue is the upscaling itself, that is, scaling lower-resolution content to 4K. In this task, the television performs quite decently. The algorithms effectively enhance the detail, resulting in a final image that is relatively sharp, clear, and readable. In this respect, it's hard to have major complaints about the device.

The situation looks completely different with materials that have a high degree of compression, which we encounter in older recordings or on platforms like YouTube with lower bitrate. Here, the processor falters in smoothing tonal transitions and masking source imperfections. The television cannot hide compression blocks, resulting in a very harsh, "digital" character of the image. The lack of effective artifact reduction can effectively discourage viewing lower-quality content on this screen.

When it comes to reducing posterization, Samsung has kept the same solutions as 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 is somewhat prone to banding. However, keep in mind it acts aggressively. This mechanism, aside from removing artifacts, can clean up fine film grain and slightly soften detail. Ultimately it’s a matter of compromise, but if you care about an absolutely faithful 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 the quality of upscaling was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still hasn’t dealt with the old overscan issue. With some older recordings or archival material the image edges can be slightly cropped. It’s a minor flaw, but it’s a shame the manufacturer still hasn’t eliminated it.

The Haier M90E is equipped with a simple yet functional motion smoothing system (MEMC). In the settings menu, the user will find a three-level adjustment scale: low, medium, and high. This allows for tailoring the degree of interference with the image to personal preferences – from gentle smoothing of 24p movies to maximum fluidity (soap opera effect). The system operates stably and fulfills its purpose in typical applications.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a refresh rate boosted to 165 Hz, though in practice the benefit will be realized mainly by 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 its job, so motion is clean and the ghosting or smearing seen on LCD screens simply doesn't occur here.

From a hardware perspective, the Haier M90E is a solid proposition. The TV is equipped with two full-bandwidth HDMI 2.1 ports, which ensures support for key technologies: VRR (variable refresh rate) and ALLM (automatic low-latency mode). A plus is also the correct implementation of the Dolby Vision mode for gaming, which maintains a relatively low input lag. Problems arise with software configuration. The biggest drawback is the forced, continuous dynamic tone mapping by the TV's processor. This prevents proper HDR calibration from the console using system panels (HGiG) – the TV ignores source settings and processes the image its own way. We also noted shortcomings in the interface: the M90E does not have a typical "Game Bar" (overlay with parameters), which is a standard among competitors. Cooperation with Xbox consoles at unusual parameters turned out to be problematic – the device has difficulty correctly displaying 1440p resolution at 120 Hz refresh rate. Despite the aforementioned shortcomings in the software, the Haier M90E remains a very attractive screen for gamers. The final impression is saved by a solid hardware base. Native panel refresh at 144 Hz and the presence of full-fledged HDMI 2.1 ports are advantages that are crucial in daily use. If we are looking for a TV that provides high fluidity and supports 4K signals, this model will fulfill its task.

Players should feel at home with the S90H, because in that respect Samsung left few reasons to complain. The TV has four HDMI 2.1 ports, each of which supports 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 in the S90H it now works as it should. What sets it apart from the competition is primarily Game Motion Plus. It's a special motion-smoothing mode designed for games, which works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so you can still play comfortably. That's important, because on many TVs turning on a similar smoothing mode causes such a large increase in input lag that controls start to feel 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 a far more useful feature.
