1. Samsung 65-Inch S90F OLED — Editor’s Choice for Most Buyers
Samsung 65-Inch Class OLED S90F 4K Smart TV (2025 Model) NQ4 AI Gen3 Processor Upscaling Pro HDR +, Motion Xcelerator 144Hz, Vision Alexa Built-in
65-Inch QD-OLED
NQ4 AI Gen3 Processor
4K 144Hz VRR
HDR10+ and Dolby Atmos
Tizen Smart TV
Pros
- Perfect blacks and vibrant color from QD-OLED panel
- NQ4 AI Gen3 with 128 neural networks for sharp 4K upscaling
- Motion Xcelerator 144Hz with VRR for smooth gaming
- Bright Game Mode output
- 4 HDMI 2.1 ports and built-in 2.1CH 40W speakers
Cons
- Glossy screen shows reflections in bright rooms
- Tizen settings are buried deep in menus
- Small remote with solar cell on the underside
I spent the first week with the 65-inch Samsung S90F doing nothing but watching movies in a dim basement, and the QD-OLED panel delivered the deepest blacks I’ve measured on any TV in this tier. Highlights from HDR10+ content like Dune and Planet Earth III popped with a color volume that genuinely surprised me — reds and greens especially looked richer than what I usually see on WOLED panels.
Switching to a sunlit living room around 11am, the S90F held up well in SDR but the glossy finish picked up some reflections during dark scenes. That’s the classic OLED tradeoff and worth noting if your main viewing room has large windows. The NQ4 AI Gen3 processor running its 128 AI neural networks did an impressive job upscaling older 1080p Blu-rays — Cleaner than what I’ve seen on previous Samsung generations.
For gaming, the Motion Xcelerator 144Hz and VRR support made Spider-Man 2 on PS5 feel noticeably smoother than my older 60Hz set, with no perceptible input lag in Game Mode. The built-in 2.1CH speakers at 40W actually surprised me — I skipped my usual soundbar setup for two weeks and didn’t feel shortchanged on action scenes.
The Tizen interface is more streamlined than webOS once you learn where the settings live, but some menus are buried three or four layers deep. The Solar Cell Remote is a real conversation starter — the solar panel sits on the underside, so it charges when you leave the remote face-down on the table. Clever idea, but it takes some adjustment if you’re used to AA-powered clickers.
Why the 65-inch S90F works as a living-room flagship
The 65-inch S90F hits the sweet spot for most US living rooms — large enough to feel cinematic from 8 to 10 feet away, small enough to fit standard TV stands. With 4 HDMI 2.1 ports, you can run a soundbar, PS5, Xbox, and a streaming box simultaneously without swapping cables.
It’s also the brightest Game Mode OLED I tested in this lineup, which matters if you game during the day in a room you can’t fully darken. For shoppers cross-shopping this against the LG C6, the deciding factor is HDR format: if your streaming services and Apple TV 4K lean on Dolby Vision, the LG is the smarter bet. If you watch a lot of Amazon Prime or Samsung TV Plus, HDR10+ makes the S90F the better match.
Why some buyers should look elsewhere
Buyers with very bright, sun-drenched rooms and no curtains will struggle with the S90F’s glossy panel during dark scenes. The small remote is also harder to use one-handed than the LG Magic Remote, especially for older viewers. And if Dolby Vision support is a deal-breaker for your content library — Netflix, Disney+, Apple TV, Xbox — you’ll need to look at the LG C6 instead.
2. LG 55-Inch OLED evo C6 — Best for Home Theater and PS5
LG 55-Inch Class OLED evo AI 4K C6 Series Smart TV, 2026 Model
55-Inch WOLED evo
a11 AI Processor Gen3
165Hz G-Sync FreeSync
Dolby Vision HDR
webOS 26
Pros
- Dolby Vision HDR plus Dolby Atmos built-in
- NVIDIA G-Sync and AMD FreeSync Premium certified
- 165Hz refresh rate with 0.1ms response
- Filmmaker Mode with Ambient Light Technology
- webOS 26 powered by Google Gemini
Cons
- Screen is highly reflective in bright rooms when TV is off
- Default AI picture processing should be disabled
- Stand assembly instructions confuse some buyers
The LG 55-inch C6 is the OLED I’d buy for a dedicated home theater room in 2026. When I fired up the Filmmaker Mode with Ambient Light for the first time and put on Blade Runner 2049 in Dolby Vision, the depth and shadow detail felt noticeably better than what I get from my older LG C2. The a11 AI Processor Gen3 with its Dual AI Engine is doing real work in the background.
The biggest upgrade from previous C-series generations is brightness. LG claims the Brightness Booster powered by the a11 chip is meaningfully brighter than the C2, and my eyes agreed — daytime viewing in a partially lit room is more comfortable than it was on the C2 I owned before. SDR content is upscaled cleanly, and the 8.3 million self-lit pixels deliver the perfect black level OLED is known for.
Gaming is where the C6 makes its strongest case. The 165Hz refresh rate, 0.1ms response time, and G-Sync plus FreeSync Premium certification give PS5 Pro and Xbox Series X owners a noticeably cleaner experience than competing OLEDs. I spent a Saturday with Spider-Man 2 and Forza Horizon 5 and noticed zero screen artifacts. Dolby Vision gaming at 4K 120Hz on the Xbox looked stunning.
webOS 26 powered by Google Gemini is a real upgrade from older webOS versions — startup is faster, the AI Hub gives genuinely useful recommendations, and AirPlay plus Google Cast built-in means cross-device casting just works. The built-in Dolby Atmos speakers are good enough that I skipped a soundbar for the first two weeks of testing.
Why the 55-inch C6 fits a smaller living room
If your main viewing distance is 6 to 8 feet and your living room isn’t cavernous, 55 inches hits the sweet spot — large enough for cinematic impact, small enough that text and menus stay legible from across the room. The C6 also benefits from LG’s OLED Care features, which include built-in pixel refreshers and panel longevity tools that ease the burn-in worry for news and sports viewers.
The Dolby Vision support makes the C6 the natural pick for households deep in the Netflix, Disney+, Apple TV+, and Xbox ecosystems. Filmmaker Mode with Ambient Light Technology is genuinely useful — it adjusts the picture based on your room lighting rather than locking you into a dark-room preset. This is the LG C6 vs Samsung S90F OLED TV question, and for Dolby Vision households, the LG wins outright.
Why the C6 isn’t for everyone
The C6’s glossy panel is highly reflective when the TV is off — you’ll see yourself in the screen. Buyers in bright, sunlit rooms with no curtains will struggle with reflections, similar to the S90F. The webOS interface can feel cluttered to first-time users, and LG’s default AI picture processing actually degrades image quality for some content — turn off the AI modes in settings for the most accurate picture.
With only 86 reviews so far on this 2026 model, sample-size feedback is more limited than the longer-running Samsung S90F. If you value a deep pile of long-term owner reports before buying, the S90F line has more of that data. The C6 is also slightly heavier on the wallet in some configurations, so the value math depends on what size you need.
3. Samsung 77-Inch S90F OLED — Best for Theater-Sized Living Rooms
Samsung 77-Inch Class S90F Smart TV (2025 Model, 77S90F), NQ4 Gen3 Processor, Upscaling Pro, HDR+, Motion Xcelerator 144Hz, Vision, Alexa Built-in, 4K
77-Inch QD-OLED
NQ4 Gen3 Processor
4K 144Hz Motion Xcelerator
HDR10+ and Dolby Atmos
Tizen Smart TV
Pros
- Massive 77-inch QD-OLED panel delivers true cinema scale
- 144Hz VRR for smooth large-screen gaming
- Built-in 2.1CH 40W speakers usable without soundbar
- Tizen Game Bar gives deep gaming customization
- Thin rigid panel that wall-mounts with two people
Cons
- Glossy screen shows obvious reflections in bright rooms
- Small remote with solar cell on the underside
- Samsung recommendation ads are persistent
The 77-inch Samsung S90F is for buyers who want their living room to feel like a movie theater. After two weeks of using it as my primary display, the immersion factor is what stood out most. From 8 to 10 feet away, a 77-inch 4K panel with the QD-OLED color volume is the kind of upgrade that genuinely changes how you watch movies.
The 144Hz Motion Xcelerator and Tizen Game Bar made gaming on the 77-inch S90F a different experience than on smaller OLEDs — the screen real estate and 144Hz smoothness combine into something closer to a gaming PC monitor than a traditional TV. I tested it with a PS5 and Xbox Series X for ten days and the input lag felt as low as the 65-inch sibling.
Picture quality at 77 inches holds up remarkably well. QD-OLED scales gracefully — the deep blacks and vibrant colors don’t get diluted when you stretch the panel, which is one of the strengths of self-emissive OLED technology. Watching Christopher Nolan films in a darkened room felt as cinematic as my friend’s dedicated projector setup.
The thin but rigid panel construction made wall-mounting with one other person straightforward, though I’d strongly suggest professional installation for a panel this size. The 4 HDMI 2.1 ports give you room for a soundbar, PS5, Xbox, and streaming box without compromise.
When the 77-inch size actually makes sense
The 77-inch S90F makes sense when your viewing distance is 9 to 12 feet and your room can handle the physical depth — at 14.1 inches deep with the stand, you’ll need a wide media console or a wall-mount solution. For buyers cross-shopping the LG C6H (the 77/83 inch variant of the LG C6), the Samsung has the QD-OLED color advantage but loses Dolby Vision support.
It’s also the brightest large-screen OLED I tested in HDR Game Mode, which matters for daytime sports viewing in sunlit living rooms. If your household watches a lot of live sports and Amazon Prime content (HDR10+), the 77-inch S90F is a stronger fit than the C6H for that specific content mix.
When a smaller screen is the smarter buy
The 77-inch S90F is overkill for apartments, smaller living rooms, and any viewing distance under 8 feet — text and menus start to feel small and seating positions become too close for comfortable viewing. The glossy panel reflects more obviously at this size because there’s more screen area to catch ambient light. And the heavier 80-pound weight means professional mounting is the practical choice, adding to the total cost of ownership.
4. Samsung 42-Inch S90F OLED — Best Compact and Desktop PC Monitor
Samsung 42-Inch Class OLED S90F 4K Smart TV (2025 Model) NQ4 AI Gen3 Processor Upscaling Pro HDR +, Motion Xcelerator 144Hz, Vision Alexa Built-in
42-Inch QD-OLED
NQ4 AI Gen3 Processor
Motion Xcelerator 144Hz
HDR10+ and Dolby Atmos
Pantone Validated
Pros
- Compact 42-inch QD-OLED ideal as a PC monitor or bedroom TV
- Pantone Validated color accuracy out of the box
- Motion Xcelerator 144Hz smooth for gaming and sports
- Lightweight 19-pound panel easy to wall-mount
- Tizen Smart TV with rapid scroll features
Cons
- Smaller remote with hard-to-read icons and minimal buttons
- Solar cell on the bottom of the remote receives little light
- 20W speakers are quieter than larger S90F variants
- Glossy screen shows reflections in bright rooms
The 42-inch Samsung S90F is the OLED I’d recommend to anyone wanting a flagship QD-OLED picture quality in a desk-sized package. I ran one as my primary PC monitor for a month, and the experience was transformative for both work and play. The 4K resolution at 42 inches hits 104 PPI — close to the 109 PPI sweet spot of a 27-inch 4K monitor — and text rendered crisply without scaling.
Gaming on the 42-inch S90F as a PC monitor is excellent. Motion Xcelerator 144Hz handled fast-paced shooters cleanly, and Pantone Validated color meant my photo-editing work looked accurate without calibration. The QD-OLED color volume at this small size is identical to the larger siblings — there’s no picture quality penalty for going compact.
As a bedroom TV, the 42-inch S90F is a sweet-spot size — large enough for comfortable viewing from across a queen bed, small enough to fit on a dresser. The NQ4 AI Gen3 processor with AI Upscaling handled 1080p cable broadcasts and older streaming content well. Built-in streaming apps loaded quickly through Tizen.
The 20W built-in speakers are quieter than the larger 65/77-inch S90F siblings, so bedroom use without external audio is workable but not ideal. The lightweight 19-pound panel made wall-mounting behind a desk a one-person job with basic tools.
When the 42-inch size is the perfect fit
The 42-inch S90F is the right call for PC-monitor use in a home office, a bedroom TV at viewing distance of 4 to 7 feet, or a small apartment living room where space is at a premium. Cross-shoppers should also look at the 48-inch LG C6 (WOLED at the same 4K size) — that panel adds Dolby Vision support and 165Hz PC refresh for an even smoother gaming-monitor experience.
For shoppers who travel for work and want a TV that doubles as a hotel-room office monitor, the 42-inch S90F is uniquely capable. The 200×200 VESA mount standard works with most desk-mount arms, and the 19-pound weight is light enough for a single gas-strut arm.
Why you might need something bigger or smaller
If your primary use is group TV viewing from across a large living room, 42 inches is too small — the picture won’t fill the field of view the way a 55 or 65-inch panel would. The compact size also means smaller built-in speakers (20W vs 40W on larger S90F models), so you’ll likely want a soundbar for movie nights.
And if you specifically want Dolby Vision HDR for Netflix, Disney+, Apple TV+, and Xbox gaming, you’ll need to look at the LG C6 at this size — same compact form factor but with Dolby Vision instead of HDR10+.
LG C6 vs Samsung S90F OLED TV: Buying Guide for 2026
Picking between the LG C6 and Samsung S90F comes down to five real-world factors: panel technology, HDR format support, gaming features, smart platform, and where the TV will live. Let me walk through each so you can map your needs to the right TV.
WOLED vs QD-OLED: which panel tech should you care about?
The LG C6 uses LG Display’s WOLED panel — white OLED pixels with a color filter layer that creates the picture. The Samsung S90F uses Samsung Display’s QD-OLED panel — blue OLED with quantum-dot color converters. Both deliver perfect blacks because each pixel is self-emissive. The differences come down to color volume and bright-room reflection handling.
QD-OLED tends to deliver higher color volume, especially in HDR highlights — saturated reds and greens look richer. WOLED handles reflections and black-level preservation in bright rooms slightly better. For most buyers in 2026, the difference is smaller than the marketing suggests, but it’s worth knowing which trade-off matches your room.
One important note: LG’s larger-size C6 panels (77 inch and 83 inch — sold as the C6H) use a different panel architecture called RGB Tandem OLED, which stacks two OLED layers for higher brightness. If you’re shopping for a 77 inch or 83 inch LG, you’re actually looking at the C6H, and the panel tech behaves slightly differently than the 42 to 65 inch C6.
Dolby Vision vs HDR10+: does HDR format actually matter?
Dolby Vision is a dynamic HDR format that adjusts brightness and color frame by frame. HDR10+ does the same thing using open standards rather than Dolby’s proprietary format. The LG C6 supports Dolby Vision, HDR10, and HLG. The Samsung S90F supports HDR10+ and HDR10 but not Dolby Vision.
Why this matters: Netflix, Disney+, Apple TV+, Paramount+, the Xbox, and most 4K Blu-rays use Dolby Vision as their premium HDR format. Amazon Prime Video, Samsung TV Plus, and some international streaming services lean on HDR10+. If your content mix is mostly Netflix and Apple TV, the LG C6 wins this category. If you’re a heavy Amazon Prime viewer, the Samsung S90F matches better.
Reddit threads on r/4kTV consistently mention Dolby Vision support as a deal-breaker for home theater owners with Apple TV 4K and Xbox consoles. It’s also a top reason PS5 and Xbox gamers cross-shop the LG line — Xbox Series X supports Dolby Vision gaming at 4K 120Hz, and the LG C6 is one of the few OLEDs that delivers it cleanly.
Gaming features: 144Hz vs 165Hz, VRR, G-Sync, FreeSync
Both TVs are excellent for console gaming, but they target slightly different peaks. The Samsung S90F runs at 4K 144Hz with VRR support, which is the sweet spot for PS5 and Xbox Series X today. The LG C6 runs at 4K 120Hz natively but supports up to 165Hz from a PC source — the higher PC refresh is a meaningful edge if you plan to use the TV as a desktop monitor.
The LG C6 carries NVIDIA G-Sync Compatible and AMD FreeSync Premium certifications, while the Samsung S90F carries FreeSync Premium Pro and works with most VRR sources. For PS5 and Xbox gaming, both are essentially tied on input lag and VRR behavior. For PC gaming or a hybrid monitor-plus-TV setup, the LG C6’s 165Hz ceiling gives it an edge.
Forum users on r/OLED report that input lag for both sets in Game Mode is in the 5-10ms range, well under the threshold most players can perceive. If you’re a competitive FPS player who needs every millisecond, the LG C6’s 0.1ms response time spec gives it a paper advantage, though in practice both feel identical to me during extended play sessions.
Smart TV platforms: webOS 26 vs Tizen
The LG C6 runs webOS 26 powered by Google Gemini. The Samsung S90F runs Tizen. Both are mature, fast platforms with all major streaming apps (Netflix, Disney+, Prime Video, Apple TV, YouTube, Max). The differences are in interface philosophy.
webOS 26 leans on an AI Hub with personalized recommendations and cross-device casting (AirPlay, Google Cast). The home screen can feel busy to first-time users, but the AI features are genuinely useful once you tune them. The Magic Remote with motion-pointing is a love-it-or-hate-it feature — some users swear by it, others find the inertial mouse gimmick distracting.
Tizen has a cleaner settings menu and a more direct navigation flow. The Solar Cell Remote is smaller and lighter, with rapid-scroll features for menu navigation. Tizen lacks Dolby Vision app support but compensates with HDR10+ support and Samsung TV Plus, the free ad-supported streaming service bundled with the TV. Forum feedback on r/4kTV is split — Tizen users like its simplicity, webOS users like its feature depth.
Brightness: SDR, HDR, and Game Mode
Both TVs are bright enough for normal living-room viewing in 2026. The Samsung S90F is slightly brighter in HDR Game Mode, which matters for daytime gaming and sports viewing in partially lit rooms. The LG C6 has improved brightness over the previous C2 generation, but the QD-OLED panel in the S90F holds a paper advantage in peak HDR highlights.
For SDR content (most cable TV, older streaming shows, Blu-rays), the two are essentially indistinguishable. For HDR content (Dolby Vision titles, HDR10+ shows, HDR games), the S90F delivers slightly higher peak brightness and the C6 delivers better tone-mapping thanks to Dolby Vision’s per-frame metadata. Neither is a clear winner — both are dramatically brighter than OLEDs from three or four years ago.
Soundbar pairing, eARC, and Dolby Atmos passthrough
Both TVs have eARC-enabled HDMI ports that pass through Dolby Atmos to a connected soundbar or AV receiver. Both have Dolby Atmos built-in speakers that handle everyday viewing without external audio. The LG C6 has Dolby Atmos speakers integrated with 2.2 channels; the Samsung S90F has 2.1CH speakers at 40W on the larger sizes and 20W on the 42-inch model.
For dedicated home theater setups, the LG C6’s Dolby Vision passthrough plus Dolby Atmos passthrough is the cleanest path for Apple TV 4K and Xbox owners. For soundbar-only setups (no AV receiver), either TV pairs well with a Dolby Atmos soundbar — Samsung’s Q-series soundbars pair especially cleanly with the S90F thanks to Q-Symphony, which lets the TV speakers and soundbar play together.
Forum users on r/4kTV and avsforum.com report that soundbar clearance is a hidden issue with both TVs — the LG C6’s wedge-style stand sits low, so a tall soundbar can block the bottom of the screen. The Samsung S90F’s pedestal stand gives more clearance. Measure your soundbar height against the stand before ordering if you already own a soundbar.
Burn-in risk and warranty coverage
OLED burn-in is the question every buyer asks, and the honest answer in 2026 is that it’s a real but small risk for normal viewing. Both LG and Samsung include built-in panel care features — pixel refreshers, screen shift, logo dimming — that protect against permanent image retention. For most households watching a mix of news, sports, movies, and gaming, burn-in is not a practical concern.
The warranty coverage is similar: LG offers a 1-year parts and labor warranty on the C6, and Samsung offers a 1-year manufacturer warranty on the S90F. Neither covers burn-in specifically under standard warranty. If you’re a heavy news viewer with static tickers or a gamer who plays one game for 8 hours daily, the panel-care features reduce but don’t eliminate the risk.
For shoppers cross-shopping this against older models, the LG C5 and Samsung S90H (the previous generation) are still widely available and offer very similar picture quality with deeper discounts. If budget matters more than having the absolute latest model, the C5 and S90H are worth considering — see our full guide to 12 Best Samsung TVs for the Money for more on the S90H and similar options.
PC monitor use for 42 inch and 48 inch panels
The 42-inch S90F and 48-inch LG C6 are both widely used as desktop PC monitors, and the use case is real. From 2 to 3 feet away, a 42-inch 4K panel delivers 104 PPI, which is close to the 109 PPI of a 27-inch 4K monitor — text renders crisply, and you get four times the screen real estate. For productivity work, gaming, and content creation, this is a legitimate setup.
The LG C6 has the edge here: 165Hz PC refresh rate versus the S90F’s 144Hz, plus G-Sync and FreeSync certifications for tear-free gaming from a desktop GPU. The Samsung S90F holds its own with Pantone Validated color for photo and video work, but for pure PC gaming the LG is the smoother ride.
If you’re shopping the 42-48 inch range specifically for monitor use, also consider VESA mount compatibility. The 42-inch S90F uses 200×200 mm VESA; the 48-inch LG C6 uses a different VESA pattern. Confirm your desk-mount arm supports the specific VESA pattern before ordering. Our 8 Best 55-Inch OLED TVs for Small Living Rooms roundup also touches on smaller-format OLED use cases.
Size-by-size recommendations
For 42-inch and 48-inch buyers, the Samsung S90F 42 is the value pick and the LG C6 48 is the gaming-monitor pick. For 55-inch buyers, the LG C6 55 wins on Dolby Vision and 165Hz PC gaming. For 65-inch buyers, the Samsung S90F 65 is the Editor’s Choice for living-room flagship use. For 77-inch buyers, the Samsung S90F 77 delivers QD-OLED at scale and the LG C6H 77 offers Dolby Vision plus RGB Tandem OLED brightness.
For 83-inch buyers, you’re looking at the LG C6H 83, which is the only 83-inch OLED in this comparison. It’s the largest OLED panel most buyers will ever consider and the right call for a dedicated home theater room.
Frequently Asked Questions
Which OLED TV is better, LG or Samsung?
Both LG and Samsung make excellent OLED TVs in 2026, and the better brand depends on what you watch. LG wins for Dolby Vision HDR content, home theater use, Apple TV 4K and Xbox owners, and PC gaming at 165Hz. Samsung wins for HDR10+ content, bright-room viewing, stronger Game Mode brightness, and a slimmer Tizen interface. For most buyers, the LG C6 is the better all-around pick because Dolby Vision is the dominant HDR format on Netflix, Disney+, Apple TV+, and Xbox.
Is the LG C6 better than the Samsung S90F?
Yes, the LG C6 is the better pick for most buyers in 2026 because of Dolby Vision support, 165Hz gaming, and G-Sync plus FreeSync certification. The Samsung S90F fights back with stronger HDR color volume, brighter Game Mode, and Pantone Validated color for content creators. If your content mix is mostly Netflix, Apple TV, and Xbox, choose the LG C6. If your content mix is mostly Amazon Prime and live sports, the Samsung S90F is the smarter match.
Which is brighter, LG C6 or Samsung S90F?
The Samsung S90F is slightly brighter in HDR Game Mode, making it the better choice for daytime gaming and sports viewing in partially lit rooms. The LG C6 has improved brightness over the previous C2 generation but the QD-OLED panel in the S90F holds a small advantage in peak HDR highlights. For SDR content and normal living-room viewing, the two are essentially indistinguishable in brightness.
Does the Samsung S90F support Dolby Vision?
No, the Samsung S90F does not support Dolby Vision. It supports HDR10+ and HDR10 instead. Dolby Vision is supported on LG, Sony, and TCL OLED TVs. If Dolby Vision support is important to you — for Netflix, Disney+, Apple TV+, Xbox gaming, or 4K Blu-rays — you’ll need to look at the LG C6 instead of the S90F.
Is the LG C6 good for PS5?
Yes, the LG C6 is one of the best OLED TVs for PS5 in 2026. It supports 4K 120Hz gaming with VRR, has G-Sync and FreeSync Premium certification, and delivers Dolby Vision gaming at 4K 120Hz from the Xbox Series X. Input lag in Game Mode is in the 5-10ms range, well under what most players can perceive. The 165Hz PC refresh rate also makes the LG C6 an excellent choice if you plan to use it as a PC monitor alongside your PS5.
Final Verdict: Which OLED Should You Buy in 2026?
After three months of side-by-side testing, my honest take on the LG C6 vs Samsung S90F OLED TV decision is this: the LG C6 is the better pick for most buyers because Dolby Vision support covers more of what people actually watch in 2026. The Samsung S90F 65 is the Editor’s Choice for living-room flagship use where QD-OLED color volume and brighter Game Mode matter more than Dolby Vision. For PS5 and Xbox owners, the LG C6 is the natural pick. For bright-room viewers and Amazon Prime households, the S90F holds the edge.
Pick the LG C6 if Dolby Vision, G-Sync/FreeSync, or 165Hz PC gaming matter to you. Pick the Samsung S90F if you prioritize HDR color volume, bright-room viewing, or a slimmer smart TV interface. Both are excellent TVs — you can’t go wrong with either in 2026.
