Samsung vs LG 55-Inch 4K TV: Which Is Cheaper Per Inch?

The Short Answer

LG wins the price-per-inch comparison at 55 inches by default: its cheapest 55-inch OLED, the 2023 C3, is $19.97 per inch ($1,098.57 at Newegg), while Samsung has no in-stock 55-inch 4K TV in our tracking. Samsung’s only tracked 4K model is a 75-inch Neo QLED at $30.93 per inch ($2,319.99), a completely different screen size. Because the automated comparison crossed screen sizes, the only measurable 55-inch floor belongs to LG.

Price Per Inch Breakdown

We divide the best tracked price by the screen’s diagonal inches to get a clean $/inch value. Each product’s best price, size, and per-inch figure comes straight from our Supabase listings on May 3, 2026:

• Samsung 75" Neo QLED QN75QN90FAFXZA – $2,319.99 at Newegg, 75 inches: $30.93/inch
• LG OLED55C3PUA (2023) – $1,098.57 at Newegg, 55 inches: $19.97/inch
• LG OLED55C5PUA (2025) – $1,179.99 at Amazon, 55 inches: $21.45/inch
• LG OLED55G3PUA (2023) – $1,486.28 at Newegg, 55 inches: $27.02/inch

The Samsung 75-inch costs 54.9% more per inch than LG’s cheapest 55-inch OLED — ($30.93 – $19.97) ÷ $19.97 = 0.549, or 54.9%. The gap widens against the premium LG G3 (84.4% higher). In display manufacturing, larger TVs typically carry a premium per inch because yields drop as screen area grows — it’s harder to produce a flawless 75-inch panel than a 55-inch one, driving up the per-inch cost. So Samsung’s $30.93/inch for a 75-inch versus LG’s $19.97/inch for a 55-inch isn’t purely a brand penalty; part of the gap stems from the size difference. The comparison is skewed by mixing screen sizes.

Same Size, Same Tier?

This isn’t an apples-to-apples comparison. While Samsung makes highly popular 55-inch TVs—like the Q60/QN90 series or S90 OLEDs—our live retail tracker simply has zero in-stock 55-inch Samsung models at this exact moment. That forces us to look at LG's in-stock options. So the two brands don’t compete at the same 55-inch size in our May 2026 tracking. LG’s floor is a 55-inch OLED; Samsung’s nearest tracked TV is a 75-inch Neo QLED — a completely different size, panel technology, and price band. No Samsung 55-inch 4K TV (OLED, QLED, or LED) appears in the live listings, so a direct per-inch match at 55 inches is impossible. The automated winner/loser engine labeled LG the winner with a floor of $19.97/inch vs Samsung’s $30.93/inch, but that engine compared a 75″ against a 55″ — a size mismatch that creates a misleading gap.

But is LG's $19.97 per inch for the 55-inch C3 a good deal in its own right? The 55-inch OLED market typically bottoms around $18–$20 per inch for clearance or older models; the C3's $19.97/inch sits right on that floor, making it a solid value for an OLED. Newer OLEDs like the C5 at $21.45/inch command a small premium for updated processing, while the brighter G3 costs more per inch. So even without a Samsung same-size rival, LG's pricing is competitive with general OLED market floors.

What the Extra Cost Buys You

Without a same-size Samsung competitor, spec comparisons remain largely academic. Still, we can highlight objective differences based on the tracked model numbers:

• The Samsung QN90F is a Neo QLED panel with a Mini‑LED backlight, offering higher peak brightness and strong HDR pop, while all three LG models are self‑emissive OLED panels with per‑pixel lighting and effectively infinite contrast — perfect for dark-room viewing.
• All models are 4K resolution and include smart TV platforms (Tizen for Samsung, webOS for LG). HDR format support differs: Samsung leans on HDR10+, LG supports Dolby Vision, which many streaming services favor.
• No 55-inch Samsung exists in our data, so evaluating whether the 54.9% higher per-inch cost of the 75-inch Samsung buys tangible 55-inch benefits is impossible. A 55-inch buyer only has LG OLED options at present.

When Each Makes Sense

• Choose LG’s 55-inch OLED if you want the lowest cost per inch at this screen size — $19.97/inch — and you value infinite contrast, Dolby Vision, and the deep blacks of self‑emissive technology. The C3 is the best value floor; the C5 adds a newer processor for a small premium, while the G3 calls for a brighter gallery‑design model at $27.02/inch.
• Choose Samsung’s 75-inch Neo QLED only if you need a much larger screen and don’t mind paying 54.9% more per inch ($30.93/inch), accepting that no 55-inch Samsung option exists in our tracking. If a 55-inch Samsung appears later, we’ll update this page with a true same-size comparison.

Verdict

LG wins the 55-inch price-per-inch comparison by default because Samsung has no measured competitor. The cheapest 55-inch 4K TV tracked is the LG C3 at $19.97 per inch. This verdict is based on live prices checked on May 3, 2026; if a Samsung 55-inch model appears, we’ll update the floor immediately.
