The LG B5 48-inch OLED (2025) at $650 is significantly cheaper than the Samsung S90H 48-inch (2026) at $1,598 — a gap of $947.99. If price is your only metric, the B5 wins. But the Samsung packs a newer processor, HDR+ support, and a glare-free screen.
The Short Answer
The LG B5 48-inch OLED wins on absolute price — $650 versus $1,598 for the Samsung S90H 48-inch. That’s a $947.99 gap. The B5 is a 2025 model; the S90H is a current 2026 OLED. When you stretch your dollar as far as possible, the B5 delivers OLED black levels at a fraction of the 2026 entry price we track.
Cost Comparison
Both displays are 48 inches, so the cost comparison is direct.
- LG B5 48-inch (2025): $650 total. Cheapest in-stock listing as of May 12, 2026.
- Samsung S90H 48-inch (2026): $1,597.99 at Amazon. The lowest-priced 2026 OLED we currently see.
No other 2026 OLED in our live data comes close to the B5's $650 price.
Same Capacity, Same Tier?
Both are 48‑inch OLED televisions, so size matches. Tier does not. The B5 is LG’s 2025 entry-level OLED; the S90H is Samsung’s 2026 mid‑tier OLED with an explicit emphasis on AI picture processing and glare reduction. The massive $947.99 price gap stems from the B5 being a 2025 model now discounted as clearance inventory, while the S90H is a 2026 model selling at its full launch MSRP. The question is whether the generational leap – newer processor, HDR+ support, and glare-free screen – justifies the premium.
What the Extra Cost Buys You
OEM specifications and listing details:
| Spec | LG B5 (2025) | Samsung S90H (2026) |
|---|---|---|
| Screen size | 48″ | 48″ |
| Panel technology | OLED | OLED |
| Glare treatment | Not stated | Glare Free |
However, it lacks the glare-free coating and HDR+ certification of the Samsung. The S90H, on the other hand, lists its NQ4 AI Gen3 Processor, OLED HDR+, and Glare Free screen explicitly. If those capabilities matter, the $947.99 premium gets you every one of them.
When Each Makes Sense
- Choose the LG B5 if you want the lowest absolute price for an OLED and don’t need the latest AI processing, HDR+ certification, or a glare‑free coating. The $650 outlay is less than half the Samsung’s total cost, and the savings are massive.
- Choose the Samsung S90H if you value advanced picture processing, HDR+ performance, and a screen that reduces reflections — and you’re willing to pay $947.99 more to get them. At $1,597.99, this is still the cheapest 2026 OLED in our tracking.
Verdict
The LG B5 48-inch OLED is the cheaper option at $650 versus $1,598 for the Samsung S90H 48-inch. As of May 12, 2026, this gap makes the B5 a compelling option for buyers who care only about getting an OLED picture for the smallest possible dollar amount. The Samsung remains the better 2026 pick if you want a modern feature set.
Frequently Asked Questions
How much cheaper per inch is the LG B5 than a 2026 OLED?
The LG B5 48-inch is $947.99 cheaper than the Samsung S90H 48-inch — $650 versus $1,597.99. The B5’s total price is less than half the S90H’s.
Does the LG B5 support HDR?
Samsung’s S90H additionally supports HDR+ with a glare‑free screen.
Is the LG B5 available in a 55-inch size within your data?
Our live TV listings show only a 48-inch B5 at $650. A 55-inch B5 does not appear in our current tracking, so the $650 price applies only to the 48-inch model.
Should I wait for the LG B6 if I want an even cheaper OLED later in 2026?
We don’t have pricing data for a future B6. The cheapest 2026 OLEDs we track now — Samsung S90H and LG C6 48-inch models — both sit above $1,500. A B6 would need to launch significantly below that to challenge the B5’s current $650 advantage.
