Hisense A6Q vs Samsung OLED S95H (S99H) (QD-OLED)

Unfortunately, the Hisense A6Q is hard to recommend for watching HDR content. The main issue remains the low brightness and quite modest coverage of a wide colour gamut. A measured brightness of about 300 nits simply isn't enough for HDR materials to look impressive. In practice, the image often resembles standard SDR rather than true HDR with clear differences in brightness and dynamics. Additionally, colours in such content do not appear as they should. The TV does not utilise additional filters like QLED or PFS LED, and a DCI-P3 coverage of around 80% makes some colours look just too pale. As a result, some scenes in HDR materials lose intensity and spectacle, making it hard to talk about a proper HDR experience.

When it comes to pure brightness, the S99H is an astronomically bright TV. Its peak brightness in film scenes can exceed 2,800 nits. Whatever the scene, you can expect powerful HDR effects that are almost blinding, which is exactly what we want from a top‑tier display. By nature, an OLED panel can't maintain that extreme brightness in very bright, full‑screen frames the way it can with small bright highlights, but the results are still excellent. In a bright scene from The Meg the sun still exceeded 2,200 nits. That means the S99H was able to hold a higher brightness than most Mini LED screens on the market. In terms of brightness the S99H is currently the best OLED TV we've tested.

Colour gamut coverage

The S99H also handles colours exceptionally well, thanks directly to the QD‑OLED panel used here. Whether the test used synthetic test patterns or measurements with film material in the background, the results remained very high. The S99H easily covers almost 100% of the DCI‑P3 gamut, and in the most demanding space, BT.2020 it reaches nearly 90%. That's absolute top‑tier performance. These results match what we saw in the new SQD‑Mini‑LED displays, and in real film scenes they even surpass RGB Mini LED displays.

We conducted the tests in the best available mode, which is Filmmaker, however – as is often the case – this does not mean the image is perfect straight out of the box. In the case of Hisense A6Q, this mode clearly “swallowed” too much blue in everyday SDR content. In practice, this led to an image with yellowed whites, particularly noticeable on large, bright surfaces. This does not result from poor assumptions of the Filmmaker mode itself or from the vision of filmmakers, but from factory settings that require adjustment.
Additionally, looking at the saturation characteristics and gamma curve in SDR, as well as EOTF in HDR content, there is a slight tendency to brighten most scenes. As a result, the image often appears brighter than it should, losing a bit of its naturalness. For this reason, we decided to perform a professional calibration to restore the proper colour balance and a more accurate brightness characteristic.

Samsung offers a whole host of picture modes and features, but we traditionally recommend choosing FILMMAKER mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor flaws. These are mainly a slight deviation in white balance in SDR content and a slightly low gamma. As a result, the picture in a dark room can be a little too bright compared with the reference value of 2.4, which is the standard for watching films with the lights off. These are, of course, small issues, because overall colour reproduction remains very good and the errors in ColorChecker measurements are not large. However, we know that for a screen of the S99H's calibre you can and should expect even more, so we subjected it to professional calibration.

Colours after calibration on the Hisense A6Q need to be evaluated in two ways, as everything depends on the type of content. In the case of SDR materials, the effect is really quite good. In daily programs, series, and movies, it’s hard to find any serious issues with colours. The yellow tint has been effectively removed, and the television has also stopped washing out the entire image. As a result, the ColorChecker test showed errors below a Delta 2 value, which are already outstanding results, allowing for a discussion of very high picture quality in standard content. Unfortunately, the situation looks much worse for HDR materials. Yes, the white balance has been corrected and the EOTF curve has been improved, but the limitations of the panel itself remain insurmountable. The lack of support for a wide colour gamut means that the television still generates quite significant colour errors. Parts of the colours simply cannot be displayed by the screen, making them look less saturated than they should. It’s a pity because even a simple PFS or QLED filter would have resulted in a significantly better end effect. The conclusion is therefore simple – for SDR content, the A6Q after calibration works really very well, while viewing HDR content on it should still be approached with caution.

After professional calibration, FILMMAKER mode looks practically perfect. Because Samsung offers a rich set of advanced calibration controls, we were able to tune the colours to an almost perfect level. Above all, we managed to even out the white balance and the gamma curve, which resulted in noticeably improved contrast and correct image modelling. In a profile prepared like this there really isn't a single thing to pick apart or call a fault. After calibration, the S99H can deliver an essentially reference-quality picture.

Upscaling on the Hisense A6Q works really well for a TV in this price range. Lower resolution materials are correctly “upscaled” to higher resolutions, and the image remains clear without any artificial edge sharpening or the typical "over-sharpening" found in cheap models. Unfortunately, the digital processing is significantly poorer. In practice, it’s hard to talk about any advanced artifact smoothing or masking of problematic tonal transitions. In heavily compressed films—especially those from YouTube—the TV struggles with reducing compression blocks and unwanted banding, making the material's imperfections clearly visible. The A6Q scales the image well, but when it comes to digital processing, it leaves the user alone with the source quality.

Upscaling and digital image processing are handled by Samsung's proprietary NQ4 Gen3 processor. It copes very well with scaling lower-resolution content to 4K. The picture is clear without looking artificial or overly sharp. The only fairly specific drawback appears with very old material recorded at 480p or lower. In such cases the TV can slightly crop the edges of the image.

The processor also does a decent job with artefacts visible in low-bitrate material, for example in heavily compressed YouTube videos. The noise reduction function effectively smooths the picture and reduces posterisation, but it works quite aggressively. It can remove not only unwanted artefacts but also some fine detail, and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image more than keeping every detail, it may prove useful.

The fluidity of motion on the Hisense A6Q is... well, quite average. It's a TV with a native refresh rate of 60 Hz in 4K, which means the movement of objects on the screen doesn't always look perfectly smooth. In dynamic scenes in films or sports, it's evident that this is not the strongest point of this model. The situation looks much better with 1080p content when connecting a console or computer, as the A6Q can then operate at up to 120 Hz. That's a big plus, especially for gamers. However, the sharpness of motion still leaves a lot to be desired, with noticeable ghosting, and the response time of the panel shows that it isn't one of the TV's strong suits.

Another major advantage of organic panels is very good motion handling. Thanks to the pixels' near-instant response time, the Samsung S99H shows virtually no smearing. Fast-moving objects don't produce visible halos or trailing artefacts, so the TV performs very well for both sport and gaming. One quirk of OLED screens compared with LCD is the way they render low-frame-rate material. With very slow camera movement the picture can appear noticeably more juddery. This can be quite effectively mitigated using frame interpolation. Samsung lets you adjust judder reduction and motion blur reduction separately, so it's easy to find a compromise between a smoother picture and preserving the cinematic feel of the content.

For such an inexpensive television, the Hisense A6Q really can surprise with what it offers gamers. It operates in 4K only at 60 Hz, but when the game switches to performance mode and drops to 1080p, the panel can work at even 120 Hz. In this price range, that's a big plus, as most titles on consoles don’t deliver a stable 4K at 120 frames. In practice, we are realistically gaming in 1080p, and here the A6Q provides a very enjoyable gaming experience. Additionally, it has a few features that are usually found in more expensive models: ALLM, VRR, and Dolby Vision Gaming for Xbox Series X/S. Everything is gathered in one place, in a simple and convenient Game Bar, so you don't need to dig through the entire menu. For such an affordable piece of equipment, it's really a solid setup for gamers — maybe not for the most demanding, but definitely spot on for occasional gaming.

Samsung S99H is also a top TV for gamers. It offers almost every possible and useful feature... well, perhaps except the obvious lack of Dolby Vision for the Xbox console. It’s equipped with four full-fledged HDMI 2.1 ports with the full 48 Gbps bandwidth. That makes it easy to use frame-rate synchronization VRR or automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and free of unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you’ll find options to add an on-screen crosshair, enlarge the minimap, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung’s feature: Game Motion Plus. It’s Samsung’s proprietary motion-smoothing system that uses interpolation to boost smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which, compared with the competition, is an excellent result. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g. GTA 6 😉) that runs on a console at only 30 fps, the S99H can display it much more smoothly than competing models.
