LG B4 55\" Price Per Inch: $13.71 vs. Cheapest TV at $3.28

What Is the LG B4 55‑Inch Price Per Inch in 2026?

The number that matters for 55‑inch OLED value in May 2026 is $13.71 per inch →. That comes from the current in‑stock price of $754 for the LG OLED55B4P, as listed in our live market data—no MSRP, no rumored discounts, just what you’d actually pay right now divided by the 55‑inch diagonal.

At that price, the B4 costs more per inch than nearly every LED and QLED screen on the market. But “per inch” is a tool for comparing like‑size displays, not a universal quality score. The real question is how it stacks up against other 55‑inch TVs and against bigger OLEDs.

The LG B4 55‑Inch vs. Other 55‑Inch TVs (LED & OLED)

To put $13.71 per inch in context, here are the cheapest 55‑inch models our tracking shows on May 12, 2026.

55‑inch LED TVs

• INSIGNIA 55‑inch Class F50 Series LED 4K UHD Smart Fire TV: $200 ($3.67/inch)
• VIZIO 55‑inch V‑Series 4K UHD HLG Smart TV: $292 ($5.31/inch)
• LG 55UA7700P 55‑inch UA77 Series LED AI 4K Smart webOS: $300 ($5.45/inch)

The cheapest 55‑inch LED is the Insignia F50 at $3.67 per inch. The LG B4 OLED costs $10.04 more per inch than that LED—a gap that reveals the OLED premium at this screen size. No QLED 55‑inch models appear in our cheapest listings, so a direct LED‑vs‑QLED‑vs‑OLED per‑inch chart at 55 inches isn’t possible right now; the cheapest QLEDs are either smaller (40″ Hisense, 32″ TCL) or 50‑inch VIZIO models.

55‑inch OLED TVs

• LG OLED55B4P 55‑inch B4 Series OLED: $754 ($13.71/inch)
• Panasonic Z85 Series (2024) 55‑inch OLED 4K Ultra HD S: $799 ($14.53/inch)

Among the two 55‑inch OLEDs we track, the LG B4 is the less expensive per inch. The difference is $0.82 per inch ($754 vs. $799), making the B4 the cost‑effective choice if you’re set on a 55‑inch OLED panel.

How the LG B4 Stacks Up Against the Cheapest Per‑Inch TVs Overall

Per‑inch efficiency drops sharply as you move away from OLED. The current floor for any in‑stock TV is the Westinghouse 58‑inch Class Smart 4K UHD Xumo TV at $190 ($3.28/inch). That’s a full $10.43 less per inch than the LG B4. Even a 43‑inch VIZIO LED at $150 ($3.49/inch) undercuts it by a mile.

At 58 inches, the Westinghouse offers HDR10 and Dolby support at $3.28/inch, and that’s the true budget benchmark if you only care about screen real‑estate for the dollar. The LG B4 isn’t trying to win that race; it’s sitting in a different lane where OLED contrast matters more than raw inches per dollar.

Is the LG B4 the Best Value 55‑Inch OLED?

If you need exactly 55 inches and you won’t accept anything other than OLED, the LG B4 delivers the lowest per‑inch cost we can verify—$13.71, beating the Panasonic Z85 55‑inch by $0.82 per inch.

But that’s only half the OLED value story. The cheapest OLED per inch overall is a larger screen: the Panasonic Z85 Series 65‑inch OLED at $665 ($10.23/inch). That’s $3.48 less per inch than the 55‑inch B4. For $89 less total, you’d get 10 more diagonal inches of OLED picture. If your space can handle 65 inches, the per‑inch math shifts decisively toward the bigger Z85.

The 48‑inch LG B5 OLED at $13.54 per inch also comes close, but for dedicated 55‑inch buyers the B4 remains the softest landing on the wallet.

Should You Buy the LG B4 in May 2026?

The data is clear. If your plan is a 55‑inch OLED, the LG B4 undercuts the nearest competitor by nearly a dollar per inch—that’s $45 less total for the same diagonal size. The Westinghouse 58‑inch LED and other budget LED sets deliver vastly lower per‑inch figures, but they aren’t OLEDs. And if you’re flexible on size, the Panasonic Z85 65‑inch OLED gives you more screen for less money overall.

Bottom line: The LG B4 55‑inch at $13.71 per inch is the value leader within its specific size and display category. It’s not the cheapest TV per inch—and it never pretends to be. For the OLED‑committed buyer who needs 55 inches, it’s the best price tracking can confirm on May 12, 2026.
