LG vs Samsung 77-inch OLED TVs (2025): B5 Series vs S90F Series
Both LG and Samsung are releasing premium 77-inch OLED 4K TVs in 2025, but at different price points. The LG B5 undercuts the Samsung S90F by $400, though both share identical quality scores and lack real-world reviews yet.
Specs Comparison
| Feature | LG B5 Series | Samsung S90F Series |
|---|---|---|
| Screen Size | 77 inches | 77 inches |

LG: Strengths and Weaknesses
Strengths:
- Price advantage: At $400 less, the B5 is a significant savings for a 77-inch flagship OLED
- webOS platform: LG's interface is widely praised for being intuitive and responsive with strong app support
- B-series positioning: Historically, LG's B-series offers solid performance without the premium markup of higher tiers
Weaknesses:
- No reviews yet: As a 2025 model, there's no independent testing to confirm performance claims
- Unknown brightness specs: The exact peak brightness and anti-glare coating details aren't specified, which matters for OLED
- AI implementation unclear: What "AI 4K" specifically does differs from Samsung's approach—upscaling quality depends on implementation
Samsung: Strengths and Weaknesses
Strengths:
- SamsungVision AI: Samsung typically invests heavily in AI upscaling for lower-res content, which can improve streaming quality
- S90F naming: This suggests premium positioning with potentially advanced features like better motion handling or gaming specs
- Tizen ecosystem: Samsung's TV OS integrates well with their broader smart home ecosystem if you use other Samsung devices
Weaknesses:
- $400 premium with no clear justification: Both TVs score identically (70/100), making the price difference hard to justify without seeing real performance differences
- No reviews or detailed specs: Like the LG, Samsung hasn't released full specifications or independent validation
- Less competitive pricing: At $1,799.99, you're paying significantly more without proven performance gains
Value for Money
The LG B5 offers superior value. At $1,399.99 for a 77-inch OLED with webOS, it's harder to recommend Samsung's $1,799.99 model when both carry identical quality scores and neither has been independently reviewed. The $400 savings with LG is meaningful—that's 22% cheaper for what appears to be equivalent core technology.
Neither purchase can be fully evaluated yet due to lack of user reviews, but the price difference doesn't correlate with any documented specification advantage for Samsung.
Verdict: Who Should Buy What?
Buy the LG B5 if:
- You prioritize value and want to save $400
- You prefer webOS's user interface
- You're comfortable buying a B-series model that skips premium tier features
Buy the Samsung S90F if:
- You're heavily invested in Samsung's ecosystem and want seamless integration
- You specifically value SamsungVision AI's upscaling approach over LG's AI 4K
- You need features specific to the S90F that LG doesn't offer (check gaming specs, motion handling once reviewed)
Final recommendation: Wait for independent reviews before either purchase. The identical quality scores suggest these are competitive products, but without real-world testing, the LG's significant price advantage makes it the safer bet.
