Samsung S99H Review: Record-Breaking OLED Brightness With One Notable Flaw

The Samsung S99H is already shaping up to be one of the finest televisions of 2026. It pushes OLED brightness to new extremes, delivers reference-grade colour reproduction, and wraps it all in a design that Samsung describes as a wall-mounted work of art. There is, however, one notable omission that prevents it from being the complete package.

Samsung has designed the S99H to look as good switched off as it does when displaying content. The panel is strikingly slim and clearly intended to blend into a living room as a piece of interior design rather than a conventional television. Build quality and finish are in line with what buyers at this price point would expect from Samsung's flagship range.

The S99H features Samsung's wireless One Connect receiver, which separates the input connections from the display panel itself. This means a single, near-invisible cable runs to the screen while all eight HDMI ports, along with the remaining connections, sit in a separate box that can be hidden away. All four primary HDMI inputs support frame rates up to 165Hz — making this an exceptionally well-equipped television for gaming as well as cinema viewing.

Samsung encourages users to set up a Samsung account during initial configuration, and doing so unlocks the full range of smart TV features and services. While the television functions without one, the experience is noticeably more complete with an account linked.

The S99H's AI-driven upscaling is described as outstanding. Lower-resolution content — including standard-definition and HD material — is processed and presented with impressive clarity and detail. For households with a mixture of content sources, this is a genuinely useful feature that elevates everyday viewing.

Out of the box, the Samsung S99H benefits from Samsung's latest picture processing, but achieving the best results requires some manual calibration. The default settings lean towards high brightness, and the automatic picture modes tend to push processing aggressively. Taking the time to dial in preferred settings — or using one of the cinema-focused presets — rewards the viewer with a significantly more natural and cinematic image.

This is the headline figure. The S99H achieves peak brightness of approximately 3,000 cd/m², comfortably surpassing its predecessor, the S95F. For HDR content, the impact is dramatic — specular highlights punch with extraordinary intensity, and the overall sense of depth and dynamism in HDR10+ material is exceptional. Combined with Samsung's matte display coating, which virtually eliminates reflections, the S99H is equally impressive in bright, daylight-filled rooms as it is in a darkened home cinema.

This is the S99H's most significant compromise. Samsung continues to support HDR10+ but does not include Dolby Vision. For many home cinema enthusiasts, Dolby Vision is the preferred HDR format, and its absence is a genuine drawback on a television at this price level. Buyers whose content libraries lean heavily on Dolby Vision — particularly through streaming services like Apple TV+ and Netflix — should factor this into their decision.

The S99H's colour reproduction is exceptional. Samsung has expanded the BT.2020 colour gamut coverage to a level described as reference-grade for an OLED television. In practical terms, this means colours are extraordinarily vivid and accurate, with subtle gradations rendered faithfully. For content mastered in wide colour gamut, the S99H delivers a viewing experience that is genuinely outstanding.

Thanks to the underlying QD-OLED panel technology, the S99H offers the best viewing angle stability available. Colour and contrast remain consistent even at wide off-axis positions, making this an excellent choice for living rooms where not every seat faces the screen directly.

Motion smoothing on the S99H is described as good overall. However, the automatic motion processing mode tends to err on the side of aggressive smoothing, which can introduce the so-called soap opera effect — making cinematic content look unnaturally smooth. Disabling or reducing the motion interpolation settings is recommended for film viewing.

The one area where the S99H takes a step back from its predecessor is audio. The built-in speakers are adequate for casual viewing, but they do not match the performance of the previous generation. For a television of this calibre, Samsung clearly expects buyers to pair it with an external soundbar or surround sound system. Given the price point, this is a reasonable assumption, but it is worth noting that the out-of-box audio experience is not exceptional.

For gamers, the S99H is superbly equipped. All four HDMI inputs support frame rates up to 165Hz, which exceeds the standard 120Hz offered by most competitors. Combined with the low input lag characteristic of OLED panels, this makes the S99H one of the best gaming displays available in a large-screen format.

• Samsung GQ55S99H — 55 inches (140cm), ideal for approximately 3 metres viewing distance
• Samsung GQ65S99H — 65 inches (164cm), ideal for 3.5 to 4 metres
• Samsung GQ77S99H — 77 inches (195cm), ideal for 4.5 metres
• Samsung GQ83S99H — 83 inches (211cm), ideal for 5 metres and above

The Samsung S99H is a genuinely exceptional OLED television. Its record-breaking brightness, reference-grade colour reproduction, virtually reflection-free matte display, and comprehensive gaming support place it among the very best televisions available in 2026. The absence of Dolby Vision remains the most significant criticism — a puzzling omission at this price tier. The built-in audio also falls short of the previous generation, making a soundbar investment strongly advisable. For buyers who can accept the Dolby Vision compromise and plan to add external audio, the S99H delivers a picture quality experience that is extraordinarily difficult to fault.
