If you have been shopping for a premium television in Hong Kong this year, the Samsung S90F OLED 4K Smart TV has almost certainly been on your shortlist. It is Samsung's 2025 mainstream OLED — self-emissive perfect blacks, up to 4K144 PC input modes in the Australian reference, Dolby Atmos, and the Tizen / Samsung Vision AI system.
The three listed sizes and prices are: 65 inch HK$10,980, 77 inch HK$22,980 and 83 inch HK$29,980, confirm current prices and stock before ordering. This guide covers what it does, which size suits your room, how it compares with the other models discussed here, and what the warranty is.
S90F specifications: confirm the supplied SKU
This guide compares published specification information. OLED panel construction can vary with screen size and sales region, so check the full SKU if QD-OLED versus WOLED matters to you. The S90F series name alone does not establish a common panel across 65, 77 and 83 inches.
- Panel: self-emissive OLED, 4K UHD (3840 × 2160)
- Refresh rate: the Australian specification lists 100Hz native refresh and up to 4K144 input in compatible PC modes. Confirm the full supplied SKU; native refresh and input modes are separate.
- Processor: NQ4 AI Gen3 with 4K AI upscaling
- HDR: OLED HDR+, HDR10+, HLG
- Gaming: VRR, FreeSync Premium Pro, Auto Game Mode (ALLM), Game Bar, Gaming Hub, Ultra Wide Game View
- Audio: 40W 2.1-channel, Dolby Atmos, Object Tracking Sound Lite, Q-Symphony
- Connections: the Australian S90F specification lists four HDMI inputs supporting up to 4K144 and eARC. This does not mean four eARC ports. Confirm the exact regional SKU, eARC port number and supported source mode.
- Platform: Tizen with Samsung Vision AI, SmartThings, Samsung TV Plus
- Voice: Confirm the available assistants, supported language and region for the full SKU; Google Assistant is not assumed from the series name.
- Design: LaserSlim — about 4 mm at its thinnest
Map each device to a supported input and reserve the labelled ARC/eARC port for TV audio return. Confirm the exact size, region and HDMI modes before planning four devices.
Why the picture is different from a QLED or Mini LED
Every pixel on an OLED panel makes its own light. When a pixel shows black it switches off completely — absolute black, no glow, no halo around bright objects. No LED, QLED or Mini LED television can do this, because they all shine a backlight through the panel and some light always escapes into the dark areas.
In practice this is what you notice on the S90F: starfields, night scenes, letterbox bars, dark interiors. If you watch films in the evening with the lights down, it is the single biggest picture upgrade available.
OLED's self-emissive pixels help with dark scenes. Colour volume, brightness and side-view performance vary with the actual panel; confirm the size and region rather than assuming every S90F has a quantum-dot layer.
⚠ Where OLED is not automatically the right answer: a very bright room with the sun coming in. LCD-based Neo QLED panels go brighter. See the comparison below.
NQ4 AI Gen3 and upscaling
The NQ4 AI Gen3 analyses each frame and reconstructs detail in lower-resolution material. This matters more in Hong Kong than the spec sheet suggests: local broadcast resolution depends on the channel and source; it should not all be described as 1080i or native 4K, and streaming is compressed. Most of what you watch is not native 4K, so how well a TV upscales affects your daily picture more often than the panel does.
HDR: HDR10+, and no Dolby Vision
The S90F supports OLED HDR+, HDR10+ and HLG. Like every Samsung TV, it does not support Dolby Vision.
HDR format availability varies by service, region, subscription, app, device and title. Dolby Vision can matter for streaming as well as discs. If it is essential, confirm the full playback route and compare a model such as the LG C6 after checking its supplied SKU.
Gaming: what the 144Hz actually means
OLED pixel response is relevant to gaming, but motion artefacts, low-frame-rate judder and input latency are separate issues. Check the required source mode and measured evidence before claiming a motion advantage. Also check:
- Up to 144Hz: a compatible PC mode, subject to the exact SKU, source and cable. PS5 and Xbox output modes depend on the game and settings; do not infer 144Hz console support from the TV specification.
- VRR and FreeSync Premium Pro — no tearing, less stutter
- Auto Game Mode (ALLM) — switches to low latency automatically when a console wakes
- Game Bar — check frame rate and latency, switch to 21:9 or 32:9 Ultra Wide Game View mid-game
- Four HDMI inputs in the identified Australian reference, all capable — no juggling cables

Sound: 40W, Dolby Atmos and Q-Symphony
A 40W 2.1-channel system with Dolby Atmos and Object Tracking Sound Lite, which moves the sound to follow on-screen action. It is genuinely decent for a panel 4 mm thick.
Consider a Sound Bar if you need different playback coverage or connections. With a compatible Samsung pairing, Q-Symphony can use the TV speakers alongside the Sound Bar; perceived sound depends on the room, content and settings. Atmos over eARC still needs a supported source track, TV passthrough and Sound Bar decoding.
Which size — reference prices and availability checks
| Size | Viewing distance | Price |
|---|---|---|
| S90F 65 inch | 2.0–2.7 m | HK$10,980 |
| S90F 77 inch | 2.5 m and beyond | HK$22,980 |
| S90F 83 inch | 2.5 m and beyond, large room | HK$29,980 |
For most Hong Kong living rooms the 65 inch is the right answer — it fits a 2.0–2.7 m sofa distance, which describes the majority of flats, and at HK$10,980 it is the accessible way into OLED.
⚠ Looking for 55 inch? The S90F does not come to us in 55. Our 55-inch Samsung OLED is the S85F at HK$6,480 — a step below the S90F in the range, but the same self-emissive OLED panel technology and a considerably lower price. For a room with a 1.7–2.3 m viewing distance that is the sensible buy.
⚠ Before ordering 77 or 83 inch, check the delivery route — lift dimensions, corridor width and doorway clearance. In Hong Kong buildings that stops more deliveries than wall strength does. Tell us the building and floor when you enquire and we will check first.

S90F or S95F? Where the extra money goes
The S95F sits above the S90F in Samsung's 2025 OLED range. Article reference prices, subject to a fresh quote:
The listed S95F reference prices are around twice the S90F figures at the compared sizes; confirm both current quotes. Compare the exact models’ picture features, Australian-reference 4K144 PC input modes and supplied-SKU connections against your needs. A Sound Bar and installation add to the total budget; this article does not establish one complete system as a measured winner.
S90F or QN90F? OLED against Mini LED
This is the comparison most people actually face — but note first that the sizes do not line up. The QN90F comes in 75, 85 and 98 inch (from HK$31,980), while the S90F is 65, 77 and 83. There is no size where you can compare them like for like.
- Choose the QN90F if your living room is genuinely bright — a big window behind or beside the sofa, afternoon sun, no curtains. Mini LED goes brighter than OLED, and in that room brightness beats contrast
- Choose the S90F if you watch mostly in the evening or with the lights down, care about film and dark-scene detail, or want the wider viewing angle for a sofa that seats several people. It is also considerably cheaper at comparable sizes
Both are strong gaming sets with 4K 144Hz. Fuller technical comparison: Mini LED vs OLED vs QLED.
S90F or LG C6?
LG's C-series is the S90F's natural rival. The model compared here is the LG OLED evo C6 (2026) — 55" HK$14,800, 65" HK$15,800, 77" HK$34,800, confirm current quote and stock.
- LG C6 advantages: Dolby Vision support, which Samsung does not offer at all; the mature webOS platform; and LG's OLEDs generally add NVIDIA G-Sync alongside FreeSync
- Samsung S90F advantages: Panel type requires confirmation; Samsung Vision AI, Gaming Hub, Q-Symphony with Samsung soundbars — and at 65 inch, HK$10,980 against HK$15,800
The simple decision rule: if you buy 4K Blu-ray discs or use an Apple TV 4K box, the Dolby Vision support makes the C6 the better fit. For streaming and gaming, compare exact panel, HDR route, PC/console modes and current prices before choosing. See our LG C6 review.
Who the S90F suits
- Evening film and series viewers — OLED black level is the upgrade you notice first
- PS5, Xbox Series X and PC gamers — 4K 144Hz, VRR, four capable HDMI ports
- Anyone upgrading from LED, QLED or Crystal UHD for the first time. This is the jump people describe as "I did not know it could look like that"
- Samsung households — SmartThings, Q-Symphony with a Samsung soundbar, phone casting
Who should look elsewhere: a very bright room facing a window (see Neo QLED), or anyone who needs Dolby Vision for discs or an Apple TV box (see the LG C6).

Frequently asked questions
What does the Samsung S90F cost in Hong Kong?
At Elechid: 65 inch HK$10,980, 77 inch HK$22,980, 83 inch HK$29,980 — confirm current prices and stock. These are international versions with a three-year on-site warranty provided by us.
What is the refresh rate of the Samsung S90F?
The Australian S90F specification lists 100Hz native refresh and four HDMI inputs supporting up to 4K144. Native refresh, supported input modes and eARC are separate specifications. 144Hz requires a compatible PC mode; confirm the full regional SKU and eARC port number for your connections.
Is the Samsung S90F good for gaming?
Check the full regional SKU and the modes required by each source. The Australian S90F reference supports up to 4K144 in compatible PC modes, but consoles and individual games may use lower frame rates. Confirm VRR, the selected HDMI input and settings; input-rate support does not establish a measured gaming ranking or guarantee no motion artefacts.
Does the Samsung S90F support Dolby Vision?
No. Like every Samsung TV it uses HDR10+ (plus OLED HDR+ and HLG) instead. HDR10+ availability depends on service, region, device and title. Dolby Vision may also matter for streaming — in that case consider the LG C6.
Do you have the Samsung S90F in 55 inch?
No — our S90F range is 65, 77 and 83 inch. For a 55-inch Samsung OLED, the S85F at HK$6,480 is the model to look at.
Which size S90F suits a Hong Kong living room?
65 inch for most flats — it suits a 2.0–2.7 m sofa distance. Go to 77 or 83 inch only if you sit 2.5 m or further back and have a genuinely large room. Check lift, corridor and doorway access before ordering the larger sizes.
S90F or S95F?
The 77-inch article reference prices are HK$22,980 for S90F and HK$48,980 for S95F, not current quotes. Compare the exact picture features, supported PC input modes and complete installation/audio budget. Neither S90F plus a Sound Bar nor S95F alone is a universal winner.
What warranty comes with it?
These are international-version sets and the warranty is provided by Elechid: free on-site inspection and repair labour within three years, with parts quoted separately if replacement is needed. Full terms are in the Delivery, installation and warranty FAQ.
The short version
S90F is a mainstream model in Samsung's 2025 OLED range. Compare the exact size, supplied panel, supported PC modes and current quote with alternatives; this is not a claim that it is the store's cheapest OLED.
WhatsApp us with your sofa distance, whether the room faces a window, and whether you game — we will tell you whether the S90F is right, or whether Neo QLED suits your room better. If a cheaper set would do the same job for you, we will say so.
Browse all OLED TVs, the full Samsung and LG ranges, or TVs chosen for home theatre. Also worth reading: the best 65-inch TVs compared and our 55 inch range.
S90F vs S95H: compare the upgrade you would actually use
If you are choosing between an older S90F offer and the newer S95H, compare the same screen size and complete supplied model first. A later year does not by itself justify a higher price. Write down your required PC or console mode, reflection needs, available cabinet space and total TV-plus-audio budget.
The Australian QA65S90FAEXXY specification distinguishes 100Hz native refresh from supported 4K144 inputs. Use that as an identified regional reference, rather than assigning its panel or input modes to every size. For the next generation, read the S95H regional specification and connection checks.
Before paying for a larger screen, use the Hong Kong TV size and viewing-distance guide. If you also need external audio, reserve the correct port using the HDMI and eARC connection guide. This is a specification-based shortlist, not an Elechid picture-quality or gaming test.
Selection notes updated 23 October 2026. Manufacturer specifications, calculated examples and actual tests are distinct; confirm the exact supply version before buying.
