The S99H is the design-led OLED in the 2026 range. Self-lit pixels do the contrast work, the NQ4 AI Gen3 processor adds 4K AI Upscaling Pro and AI Motion Enhancer Pro, and the Glare Free screen, which Samsung says was validated by UL against the UGR glare standard, keeps window reflections from sitting on top of the image.
The body is a FloatLayer design, bezel-less on four sides, under 30 millimetres deep and raised on round feet. Sound is a 70 W 4.2.2ch system with Dolby Atmos, Object Tracking Sound+ and Q-Symphony. Tizen brings Vision AI Companion, the Art Store and Generative Wallpaper, and the set doubles as a SmartThings and Matter hub with Zigbee and Thread built in.
Buy this one for the built-in sound and the FloatLayer body: a 4.2.2 channel system removes the usual reason to order a soundbar on day one.
Ideal For
Buyers who want built-in sound
The 70 W 4.2.2ch system with Object Tracking Sound+ and Dolby Atmos goes further than most flat panels, and Q-Symphony still adds a soundbar later.
Bright, glare-prone living rooms
The Glare Free screen, which Samsung says UL validated against the UGR standard, cuts the mirroring that normally forces OLED owners to close the curtains.

Contrast without a backlight
OLED pixels generate their own light, so the set can hold a bright highlight next to genuine black with nothing bleeding between them. HDR arrives as HDR10+ Adaptive, HDR10+ Gaming and HDR10+ Advanced plus HLG, and the NQ4 AI Gen3 processor handles upscaling for the broadcast and streaming material that still is not 4K. AI Motion Enhancer Pro is aimed at sport, where fast pans are where cheaper processing usually falls apart.
A sound system you can live with
Seventy watts across 4.2.2 channels is a real speaker layout rather than a token one, with up-firing drivers for the height information in a Dolby Atmos mix. Object Tracking Sound+ moves effects to match what is happening on screen, Active Voice Amplifier Pro lifts dialogue when the room gets noisy, and Q-Symphony means a compatible Samsung soundbar plays with the television speakers instead of switching them off.
Wireless One Connect, explained
Samsung lists this line as Wireless One Connect Ready. The optional box takes your sources and sends the signal to the screen, allowing consoles and boxes to sit up to ten metres away and leaving only power at the panel. It is genuinely useful for a wall-mounted installation, but it is an accessory sold separately: nothing in the television carton performs that job, so budget for it if the neat cabling is the reason you are buying.

The Verdict
Why it stands out
- Self-lit pixels deliver black without any blooming

- 70 W 4.2.2ch Atmos audio needs no soundbar
- 165 Hz variable refresh across all four HDMI ports
- Art Store and Generative Wallpaper built into Tizen
Worth knowing
- No One Connect box is supplied. The set is Wireless One Connect Ready, and the wireless box itself is an optional accessory that Samsung sells separately.
- Dolby Vision is not supported. Dynamic HDR is covered by HDR10+ Adaptive, Gaming and Advanced alongside HLG, which most streaming services in Ireland now carry.
- Energy class and VESA pattern both change between sizes in this line, so check each against your wall bracket and your running costs before ordering.
