55" OLED 4K 165Hz Smart TV

The Samsung S90H series delivers a 55-inch OLED panel with 4K resolution and a 165Hz refresh rate. Self-illuminating pixels produce deep contrast and wide viewing angles without a backlight. Graphite Black finish and a bezel-less LaserSlim design suit modern living spaces. The set runs the Tizen One UI platform with built-in voice assistants and Samsung TV Plus.

Buyers who want AI-enhanced picture

The NQ4 AI Gen3 processor uses 128 neural networks for 4K AI upscaling, motion enhancement and real-time HDR remastering. Gamers gain VRR, ALLM, FreeSync Premium Pro and G-SYNC compatibility through four HDMI inputs. Wi-Fi 6E provides high-throughput wireless connectivity. Households needing more than four HDMI ports or a smaller screen diagonal should consider other models.

165Hz refresh rate decides fit for high-frame-rate

Motion Xcelerator 165Hz supports ultra-smooth 4K gameplay at up to 165 frames per second with tear-free variable refresh rate. If the primary use is 60Hz broadcast or streaming only, the extra refresh headroom may be unnecessary. The panel’s 3840 x 2160 resolution and 16:9 aspect ratio remain standard for current 4K content.

Questions about this item

Do I need an HDMI 2.1 cable to use the 165 Hz refresh rate?

Yes — the panel supports 165 Hz and the set has four HDMI inputs, so a certified Ultra High Speed HDMI cable is required to pass the full bandwidth.

Will my older soundbar that only has optical input work with this TV?

The TV provides a 2.1 channel speaker system and eARC on one HDMI port; if your soundbar only accepts optical you will need an HDMI-to-optical audio extractor.

How can I verify the 165 Hz mode is active after I connect my PC?

Open the Game Bar overlay on the TV or check the on-screen information banner — it will report 3840 x 2160 at 165 Hz when the signal is correctly recognised.
