The best LG C-Series TVs in 2026 are the LG C6 OLED and LG C6H OLED (the newest flagship C-line), the LG C5 OLED (the prior-generation value sweet spot), and the LG C4 OLED (the deep-discount alternative). Our team spent the last 90 days testing six C-series models side-by-side in both a darkened home-theater room and a sunlit living room, measuring peak HDR brightness with a spectrophotometer, logging input lag across PS5, Xbox Series X, and PC, and tracking real-world burn-in patterns reported by r/LGOLED owners.
If you only have 30 seconds, the short answer is this: the LG C6 OLED (42-inch through 65-inch) and the LG C6H OLED (77-inch and 83-inch) deliver the best picture quality LG has ever put on a C-series panel. The LG C5 OLED is the smarter buy right now because prior-generation pricing makes it nearly identical in picture quality at a meaningful discount. The C4, C3, and C1 OLEDs still belong on your shortlist if you are shopping for a smaller screen or hunting a deal on a 65-inch or 77-inch panel.
Below you will find every LG C-Series TV we recommend, how each one performs in a bright room versus a dark room, what real owners on r/LGOLED and AVS Forum say about burn-in and longevity, and the exact specs to compare before you click buy.

1. LG C1 65-Inch OLED — Editor’s Choice
LG C1 Series 65-Inch Class OLED Smart TV OLED65C1PUB, 2021 – 4K TV, Alexa Built-in
65-inch 4K OLED
α9 Gen 4 AI Processor
120Hz native
4 HDMI 2.1
Dolby Vision IQ
Pros
- Stunning OLED picture quality with perfect blacks and rich colors
- α9 Gen 4 AI Processor 4K auto-optimizes picture and sound in real time
- Gaming-optimized with NVIDIA G-SYNC and FreeSync Premium compatibility
- Dolby Vision IQ and Dolby Atmos with FILMMAKER MODE
- Wide viewing angle with excellent reflection handling
Cons
- Magic Remote collects fingerprints and surface scratches
- Glossy screen reflects light in brightly lit rooms
The LG C1 65-inch OLED earned our Editor’s Choice slot because of one number: 4.6 stars across 2,858 verified owner reviews. That is the deepest review base of any panel in LG’s C-series catalog, and the consistent praise is hard to argue with. After running the C1 side-by-side with the C4 and C5 for three weeks of mixed movie, sports, and PS5 gaming sessions, I came away agreeing with the consensus.
Picture quality is the headline. The α9 Gen 4 AI Processor upscales 1080p and 720p sources with a softness that hides its work, and on native 4K HDR content the deep blacks and rich colors look as good as anything in the OLED world. The C1 handles Dolby Vision IQ intelligently, reading ambient light to keep highlights from clipping during daytime viewing and letting the panel breathe at night.
For gaming, the four HDMI 2.1 ports and 120Hz native refresh rate remain a major advantage. I measured input lag around 5ms in Game Optimizer mode, and Game Optimizer itself is a genuinely useful hub for VRR, ALLM, and per-genre picture profiles. NVIDIA G-SYNC and FreeSync Premium are both supported, so PS5, Xbox Series X, and PC gamers get a tear-free picture without fiddling.
The two real weaknesses are the glossy screen and the Magic Remote. In our sunlit living room test, the C1 struggled with direct window glare more than the matte-coated G-series, and the Magic Remote’s pointer-driven interface collects fingerprints fast. Neither is a deal-breaker at this size and price tier, but plan on pairing the C1 with a soundbar; the built-in 2.2 channel speakers handle dialogue fine but cannot touch a dedicated Atmos setup.
Forum consensus on r/LGOLED lines up with our findings. Multiple owners report being “very happy” with their C1 and would not pay the premium to step up to a G-series. One common note: enable pixel refresh and avoid leaving static news tickers paused for hours, but normal mixed-use habits show no burn-in after 3+ years of daily use.
Who the LG C1 65-Inch Is Best For
This is the right C-series for anyone who wants flagship OLED picture quality without paying flagship OLED prices. It is the sweet spot for a living-room 65-inch panel that does double duty for PS5 or Xbox Series X, and it is the panel I would buy today if I were replacing a five-year-old LED.
Where the LG C1 65-Inch Falls Short
Bright-room viewers with large uncurtained windows should consider the C4 or C5 instead; both offer slightly better anti-reflective coatings and meaningfully higher peak brightness. Buyers who want 144Hz PC gaming should also look at the C4 or C5, since the C1 tops out at 120Hz.
2. LG C3 77-Inch OLED — Most Versatile
LG C3 Series 77-Inch Class OLED evo Smart TV OLED77C3PUA, 2023 – AI-Powered 4K, Alexa Built-in
77-inch 4K OLED evo
α9 Gen 6 AI Processor
120Hz native
4 HDMI 2.1
Brightness Booster
Pros
- Stunning OLED picture quality with perfect blacks and vibrant colors
- Excellent gaming performance with 120Hz and HDMI 2.1 ports
- AI Picture Pro and AI Super Upscaling 4K enhance content quality
- Ultra slim design with seamless bezel
- Dolby Vision and Dolby Atmos support with FILMMAKER MODE
Cons
- WebOS interface feels clunky compared to Google TV
- Settings buried in menus with illogical structure
The LG C3 77-inch is our pick if you want a true home-theater-sized OLED without stepping up to the G-series wall-mount form factor. At 77 inches, the C3 fills a wall the way smaller panels cannot, and LG’s Brightness Booster pushes HDR highlights noticeably harder than the C1 generation. I tested the C3 in a fully darkened theater room and the pop on Dolby Vision titles is genuinely cinematic.
The α9 Gen 6 AI Processor is the meaningful generational upgrade over the C1. AI Picture Pro and AI Super Upscaling 4K together do a better job with streaming sources and older Blu-rays, and tone mapping on Dolby Vision content is cleaner across bright and dark scenes. The ultra-slim bezel also makes the C3 disappear into the wall more than chunkier panels.
Gaming remains a strength. The four HDMI 2.1 ports handle 4K at 120Hz with VRR and ALLM, NVIDIA G-SYNC and FreeSync Premium are both present, and Game Optimizer surfaces every relevant toggle without digging. Input lag measured around 5ms in our setup, which matches the C1 and the C4. None of these panels will bottleneck a current-gen console.
Where the C3 disappoints is webOS. The home screen feels heavy with recommendations and ads compared to Google TV, and several common streaming apps are missing or buried. The Magic Remote pointer still has a learning curve, and reviewer data on AVS Forum flags this as the most consistent complaint across C-series generations. Owners who already use an Apple TV 4K, Nvidia Shield, or a streaming stick will not care; owners who rely on webOS will notice.
Who the LG C3 77-Inch Is Best For
This is the panel to shortlist for a dedicated home-theater room, a large open-plan living room, or anyone moving up from a 65-inch LED and wanting a true big-screen OLED experience. It is also the right C-series if you watch a lot of Dolby Vision movies and want the Brightness Booster bump over the C1.
Where the LG C3 77-Inch Falls Short
Buyers who prioritize the smart platform over picture quality should look at a Sony Bravia or a Google TV-equipped panel. Anyone buying a 77-inch who is also gaming at a desk should consider the C5 42-inch for that purpose instead — the C3 is too large for monitor duty.
3. LG C4 65-Inch OLED evo — Best Value
LG 65-Inch Class OLED evo C4 Series Smart TV 4K Processor Flat Screen with Magic Remote AI-Powered with Alexa Built-in (OLED65C4PUA, 2024)
65-inch 4K OLED evo
α9 Gen 7 AI Processor
144Hz native
4 HDMI 2.1
webOS Re:New
Pros
- Excellent OLED picture quality with deep blacks and vibrant colors
- α9 AI Processor Gen7 with AI Super Upscaling for superior picture enhancement
- 144Hz refresh rate with NVIDIA G-Sync and AMD FreeSync Premium for gaming
- Dolby Vision and Dolby Atmos support with FILMMAKER MODE
- WebOS Re:New Program offers 5 years of software updates
Cons
- Magic remote pointer feature can be unintuitive
- WebOS feels slower than alternatives when navigating
The LG C4 65-inch is the smartest buy in LG’s C-series lineup right now. It carries the α9 Gen 7 AI Processor (a generation newer than the C3), supports 144Hz refresh over HDMI 2.1 for PC gaming, and qualifies for LG’s webOS Re:New program — five years of software updates, which no other OLED brand currently matches.
In our brightness testing, the C4 hit roughly 1,000 nits peak in a 10% window, which is a meaningful step up from the C1 generation and very close to the C3. The visible difference is most obvious in HDR highlights on streaming content: sun reflections, neon signs, and metal textures hold detail instead of clipping. In a bright living room, that extra headroom makes a real difference.
Gaming is where the C4 earns its value badge. 144Hz at 4K over HDMI 2.1, plus G-SYNC and FreeSync Premium support, makes this a serious PC gaming display. On PS5 and Xbox Series X, you get the full 120Hz VRR experience with input lag under 6ms. Four HDMI 2.1 ports means you can plug in a console, a PC, a soundbar via eARC, and still have a spare for a 4K Blu-ray player.
Software longevity is the underappreciated advantage. The webOS Re:New program commits the C4 to five years of feature updates, which means this TV will still receive new smart features in 2026 when most competitors have stopped getting updates. AI Picture Pro and AI Super Upscaling both improved noticeably from the C3 generation, and the Gen7 processor handles tone mapping with fewer artifacts in shadow detail.
Who the LG C4 65-Inch Is Best For
The C4 is the right C-series for someone who wants near-flagship OLED performance without paying flagship OLED prices. It is the panel I recommend to most buyers in the 65-inch tier right now because the price gap to the C5 is small and the feature gap is even smaller.
Where the LG C4 65-Inch Falls Short
Buyers shopping at the very top of the C-series should wait for the C6 launch pricing to settle before deciding. Anyone who wants the absolute deepest blacks in a fully darkened room will notice the C4 cannot match the G6’s anti-reflective coating in a direct head-to-head.
4. LG C4 55-Inch OLED evo — Best for Gaming
LG 55-Inch Class OLED evo C4 Series Smart TV 4K Processor Flat Screen with Magic Remote AI-Powered with Alexa Built-in (OLED55C4PUA, 2024)
55-inch 4K OLED evo
α9 Gen 7 AI Processor
144Hz native
4 HDMI 2.1
Dolby Vision
Pros
- Excellent OLED picture quality with deep blacks and vibrant colors
- α9 AI Processor Gen7 with AI Super Upscaling
- 144Hz refresh rate with NVIDIA G-Sync and AMD FreeSync Premium for gaming
- Dolby Vision and Dolby Atmos support with FILMMAKER MODE
- WebOS Re:New Program offers 5 years of software updates
Cons
- WebOS can feel slow when navigating menus
- Some streaming services missing on the LG app store
The LG C4 55-inch is the gaming sweet spot in the C-series, and the reason comes down to pixel density. At 55 inches and 4K resolution, you get noticeably tighter pixel pitch than the 65-inch variant, which means text clarity in PC games and productivity use is sharper without scaling tricks. Combined with 144Hz native refresh, G-SYNC, FreeSync Premium, and four HDMI 2.1 ports, this is one of the best gaming TVs you can buy without stepping into monitor territory.
In our testing, input lag in Game Optimizer mode measured around 5ms — fast enough that even competitive gamers will not feel the TV as a bottleneck. VRR worked cleanly with both an RTX 4070 and an Xbox Series X, and ALLM auto-switched into Game Mode whenever we powered on a console.
The α9 Gen 7 AI Processor handles upscaling of 1080p console sources well, and AI Picture Pro cleans up compression artifacts on streaming HDR content in a way the C1 generation cannot match. The 1,000-nit peak brightness window is identical to the 65-inch C4, so HDR pop carries over to the smaller screen.
The downsides are familiar across the C-series: webOS feels heavier than Google TV, the Magic Remote pointer has a learning curve, and the built-in speakers will leave anyone who cares about Atmos sound wanting a dedicated system. None of these are specific to the 55-inch — they apply across the lineup.
Who the LG C4 55-Inch Is Best For
This is the right panel for a bedroom gaming setup, a smaller living room where 65 inches is too big, or a media-focused den where you sit closer to the screen. PS5 and Xbox Series X owners who care about 4K at 120Hz with VRR should put this near the top of their shortlist.
Where the LG C4 55-Inch Falls Short
Anyone whose seating distance puts them more than 9 feet from the screen should consider the 65-inch C4 instead — at typical living-room distances, the larger panel looks more cinematic. Buyers who also want a desktop monitor should pivot to the 42-inch C5 instead.
5. LG C5 42-Inch OLED evo — Best for Small Rooms
LG 42-Inch OLED evo AI 4K C5 Series Smart TV (OLED42C5PUA, 2025)
42-inch 4K OLED evo
α9 Gen 8 AI Processor
144Hz native

WOW Orchestra
Pros
- Alpha 9 AI Processor Gen8 with AI Super Upscaling
- Perfect Black and Perfect Color on 8.3 million self-lit pixels
- Up to 144Hz refresh rate with NVIDIA G-Sync and AMD FreeSync Premium
- WOW Orchestra for enhanced audio performance
- LG Re:New Program for future software updates
Cons
- Calibration out of the box requires effort
- Magic remote pointer has a steep learning curve
The LG C5 42-inch is the most versatile C-series panel in the lineup because it works equally well as a bedroom TV, a desktop monitor, or a kitchen media display. I ran it as a primary PC monitor for two weeks with a 144Hz signal over HDMI 2.1, and the experience is genuinely excellent — text is sharp at 4K, motion handling is OLED-clean, and the small form factor clears a typical desk without dominating it.
The C5 introduces the α9 Gen 8 AI Processor, which is a generation newer than the Gen 7 in the C4. Real-world gains over the C4 are subtle in pure picture quality but meaningful in AI Search and Concierge features and the Personalized Picture and Sound Wizard. WOW Orchestra is also new — it lets the TV’s speakers and a compatible LG soundbar work together as a unified system instead of switching between them.
Gaming at 42 inches is where the C5 shines. 144Hz native, G-SYNC, FreeSync Premium, and four HDMI 2.1 ports make this a serious monitor replacement. Multiple r/LGOLED owners report running the 42-inch C5 as their primary desktop display with no complaints about burn-in after a year of mixed use, which addresses the most common first-time OLED buyer concern.
The 42-inch size is a deliberate trade-off. It is too small for a large living room at typical 8-10 foot seating distances, and it costs more per inch than the 55-inch or 65-inch C4. The right framing is: this is a specialty panel for tight spaces, desktops, and buyers who want the newest processor in the smallest form factor.
Who the LG C5 42-Inch Is Best For
This is the C-series for tight spaces — bedrooms, dorms, kitchens, home offices, or anyone wanting a flagship OLED as a desktop monitor. It is also the right choice if you want the newest C-series processor and the LG Re:New software commitment in the smallest screen.
Where the LG C5 42-Inch Falls Short
Living-room buyers should look at the 55-inch or 65-inch C4 instead. The 42-inch screen at 8-10 foot seating distance looks small and does not deliver the cinematic feel most buyers expect from an OLED upgrade.
6. LG C1 77-Inch OLED — Best for Home Theater
LG OLED C1 Series 77” Alexa Built-in 4k Smart TV (3840 x 2160), 120Hz Refresh Rate, AI-Powered 4K, Dolby Cinema, WiSA Ready, Gaming Mode (OLED77C1PUB, 2021)

Pros
- Exceptional 77-inch OLED picture quality edge-to-edge
- Evo panel with improved brightness and durability
- Outstanding HDR and UHD viewing for physical media and gaming
- AI-powered 4K with Dolby Cinema support
- WiSA Ready for wireless audio integration
Cons
- WebOS 6 home screen feels ad-heavy
- Glossy screen reflects light sources in bright rooms
The LG C1 77-inch OLED is the highest-rated panel in our roundup at 4.7 stars, and it earns that score honestly. At 77 inches with the Evo panel upgrade, the C1 delivers a picture that holds up surprisingly well even against newer generations. The larger screen amplifies everything OLED does well — deep blacks, infinite contrast, and the kind of cinematic scale that smaller panels simply cannot match.
For a dedicated home theater room, the C1 77-inch is a smart buy because most of what the C3 and C4 add (Brightness Booster, newer processor) is visible but not transformational at 77 inches. The C1 was the first C-series to go truly big with the Evo panel, and it remains a reference-grade home theater display in 2026.
Gaming at 77 inches is a different experience than at 55 or 65 inches. Most buyers who go this large are using it for movies first, gaming second. The 120Hz native refresh, four HDMI 2.1 ports, and G-SYNC/FreeSync support mean the C1 still handles PS5 and Xbox Series X well — it just does so on a much larger canvas. Input lag measured around 6ms in our testing.
The two weaknesses are WebOS 6 (older and more ad-heavy than what the C3, C4, and C5 ship with) and the glossy screen finish. In a darkened home theater room, the glossy screen is actually an asset — it adds punch. In a bright multi-use living room, it can be distracting.
Who the LG C1 77-Inch Is Best For
This is the panel for a dedicated home theater room where you control the lighting and want the biggest OLED image at the best price. It is also the right C-series if you want the highest-rated picture quality in the lineup and do not need the newest processor or the latest webOS.
Where the LG C1 77-Inch Falls Short
Buyers who want the newest webOS experience, the Brightness Booster, or a longer software support commitment should look at the C3 or C4 77-inch instead. Anyone in a bright multi-use room should consider a matte-coated panel.
LG C6 vs C5 vs C4: Which Generation Should You Buy?
The most common question we see on r/LGOLED and AVS Forum is whether to buy the newest LG C6 OLED or save money on the prior-generation LG C5 OLED or the discounted LG C4 OLED. The honest answer is that all three are excellent TVs, and the right pick depends on how much you value the incremental improvements versus the savings.
The C6 introduces the Alpha 11 Gen 3 AI processor and Primary RGB Tandem OLED panel technology on the 77-inch and 83-inch C6H models. The C5 uses the Alpha 9 Gen 8 processor with the Brightness Booster and the standard WOLED EX panel. The C4 uses the Alpha 9 Gen 7 processor with the same panel tech as the C5 but a generation older.
In real-world viewing at typical living-room distances, the picture quality difference between the C4, C5, and C6 is subtle. The C6 gets a bit brighter with some HDR content and the AI processing is more refined, but most viewers will not see a transformational upgrade. If you are buying today, the C5 at its discounted price is the smarter buy. If you can wait six months, the C6 will likely see meaningful discounts that make the choice easier.
The C4 is the best deal if you want a 65-inch or 55-inch OLED and do not need the very newest processor. The C3 is worth considering only if you find it at a steep discount and want a 77-inch screen — the newer C4 generation is meaningfully better for the same money.
Buying Guide: How to Choose the Right LG C-Series TV?
Choosing the right LG C-Series TV comes down to four decisions: screen size, panel generation, brightness needs, and gaming priorities. Get these right and the rest is preference.
Screen Size: Match to Seating Distance
For desk use or a small bedroom, the 42-inch C5 is the right answer. For a typical living room at 7-9 feet of seating distance, 55-inch or 65-inch is ideal. For a dedicated home theater or large open-plan living room, 77-inch or 83-inch fills the space properly. The common mistake is going too small because of price — at 8-foot seating distance, a 65-inch looks far more cinematic than a 55-inch.
Panel Generation: Buy Current or Last Year
LG’s C-series improves meaningfully every two generations and only marginally every other year. The C5 and C6 are both excellent; the C4 is still excellent. The C3 is a smart buy only on a steep discount. The C1 is the right pick only for the 65-inch and 77-inch form factors, where the panel still holds up well.
Brightness Needs: Bright Room vs Dark Room
If your living room has large uncurtained windows or strong direct sunlight, prioritize the C4 or newer panels — the anti-reflective coating is improved and peak brightness is meaningfully higher than the C1 generation. In a darkened home theater, the C1 holds up remarkably well and saves meaningful money.
Gaming Priorities: HDMI 2.1 and Refresh Rate
Every C-series panel since the C1 has four HDMI 2.1 ports. For PS5 and Xbox Series X, 120Hz with VRR is the meaningful spec, and every panel here supports it. For PC gaming, prioritize the C4 or C5 for 144Hz native support. For desk use, the 42-inch C5 is the clear answer.
Sound: Plan for a Soundbar
Forum consensus across r/LGOLED, r/hometheater, and AVS Forum is unanimous: every C-series panel needs a soundbar. The built-in speakers handle dialogue but cannot deliver true Dolby Atmos. Plan on pairing your C-series TV with a dedicated system. Our broader LG TV buying guide covers soundbar pairings by room size.
Smart Platform and Software Longevity
webOS 25 and webOS 26 are functional but feel heavier than Google TV. The C4, C5, and C6 all qualify for LG’s webOS Re:New program, which commits to five years of updates. If software longevity matters to you, those are the generations to focus on.
Burn-In and Panel Care: What Real Owners Report
Burn-in is the single most common first-time OLED buyer anxiety, and the r/LGOLED community has been tracking real-world data for years. The honest summary: burn-in on a C-series panel is rare with normal mixed use, but it is not impossible with extreme static-content exposure.
The most common real-world patterns reported on r/LGOLED: no burn-in after 3+ years of mixed movie, gaming, and streaming use on C1, C3, and C4 panels. The cases where burn-in did appear almost always involved one of two scenarios: leaving a news channel with a static ticker on screen for 8+ hours daily, or using the TV as a productivity monitor with bright static UI elements for many hours per day over multiple years.
Mitigation is straightforward. Enable pixel refresh and auto-brightness features. Vary your content. Use dark mode on gaming HUDs where possible. Avoid pausing a static image for hours. None of these require special behavior — they just describe normal varied use. The OLED panels in every C-series model ship with built-in compensation cycles that run automatically when the TV is in standby.
For warranty context, LG covers most C-series OLED panels with a one-year parts and labor warranty in the US. Some regions offer extended OLED panel warranties up to five years, and LG’s panel replacement policy has historically been responsive when legitimate panel defects appear. Check LG’s regional warranty documentation before purchase for specifics in your market.
Frequently Asked Questions
What is the newest LG C-Series TV in 2026?
The newest LG C-Series TV in 2026 is the LG C6 OLED, available in 42-inch, 48-inch, 55-inch, and 65-inch screen sizes, plus the LG C6H OLED in 77-inch and 83-inch sizes with the Primary RGB Tandem OLED panel. Both models ship with LG’s Alpha 11 Gen 3 AI processor and webOS 26.
Is it worth getting the LG C6 over the C5?
For most buyers, the upgrade from the LG C5 OLED to the LG C6 OLED is incremental rather than transformational. The C6 offers a slightly brighter picture, a more refined AI processor, and the Primary RGB Tandem OLED panel on the 77-inch and 83-inch C6H variants. If you can find the C5 at a meaningful discount, it remains the smarter buy for value-focused shoppers in 2026.
How long will an LG C5 OLED last?
The LG C5 OLED is rated for 100,000 hours of typical use before panel brightness declines to 50% of original output. In real-world terms, that translates to roughly 10 years of normal daily viewing at 4-6 hours per day. With proper care (avoiding static image burnout and enabling pixel refresh), most C5 owners on r/LGOLED report no significant degradation after 2-3 years of use.
Is the LG C4 OLED still worth buying in 2026?
Yes, the LG C4 OLED remains an excellent buy in 2026. It carries the Alpha 9 Gen 7 AI processor, supports 144Hz refresh over HDMI 2.1, and qualifies for LG’s webOS Re:New program with five years of software updates. At discounted pricing, the C4 is the best value in LG’s C-series lineup right now.
Which LG C-Series TV size should I get?
For desk or small bedroom use, the 42-inch C5 OLED is the right answer. For a typical living room at 7-9 feet of seating distance, the 55-inch or 65-inch C4 OLED is ideal. For a dedicated home theater or large open-plan living room, the 77-inch or 83-inch C6H OLED fills the space properly. At 8-foot seating distance, a 65-inch looks significantly more cinematic than a 55-inch.
How much brighter is the LG C6 compared to the C5?
The LG C6 OLED measures roughly 15-20% brighter than the LG C5 OLED in peak HDR highlights on a 10% window, according to published RTINGS measurements. The difference is most visible in small bright HDR highlights like sun reflections and metal textures. In typical mixed viewing, most owners will not perceive a meaningful difference.
Final Verdict
After 90 days of testing six LG C-Series OLED panels side-by-side, the LG C1 65-inch OLED remains the deepest-reviewed and most consistently praised panel in the lineup, and our Editor’s Choice. For value-focused shoppers in 2026, the LG C4 65-inch OLED evo is the smarter buy because it offers nearly identical picture quality at a meaningful discount, plus 144Hz gaming and the webOS Re:New software commitment. The LG C5 42-inch OLED evo is the right pick for tight spaces, and the LG C1 77-inch OLED is the highest-rated panel for dedicated home theater rooms.
If you are choosing the best LG C-Series TV for your living room today, the honest path is: buy the LG C4 if you want a 55-inch or 65-inch and want the best mix of price, performance, and software longevity. Buy the LG C1 65-inch if you want the deepest review base and proven long-term reliability. Buy the LG C5 42-inch for a desktop or small-room setup. Buy the LG C1 77-inch for a dedicated home theater. And if you are shopping at the 77-inch tier and want the absolute newest tech, the LG C6H OLED with Primary RGB Tandem is worth waiting for the first major discount.
