65-Inch TV Price-Per-Inch Leaderboard (May 2026)
To put the S5’s number in context, here is how every 65-inch TV in our live listings stacks up by price per inch on May 3, 2026:
| Model | Price | $ per inch |
|---|---|---|
| TCL 65S55 (LED) | $420 | $6.46 |
| TCL 65Q651G (QLED) | $440 | $6.77 |
| Samsung QN65S90DAFXZA (OLED) | $944 | $14.53 |
| LG 65" B5 OLED (2025) | $950 | $14.62 |
The TCL S5’s $6.46/inch undercuts its QLED sibling, the TCL Q6 (65Q651G), by $0.31 per inch. That might sound small, but across a 65-inch diagonal it translates to a $20 total savings — money that can go toward a soundbar or wall mount.
At the high end, both the Samsung S90D OLED and the LG B5 OLED cost more than twice as much per inch. The Samsung OLED’s $14.53/inch is 125% higher than the S5’s ($14.53 − $6.46 = $8.07 more per inch; $8.07 / $6.46 = 1.249). The LG B5’s $14.62/inch is 126% higher ($14.62 − $6.46 = $8.16; $8.16 / $6.46 = 1.263). These OLEDs deliver better contrast and black levels, but they demand a steep premium for that picture quality.
S5 vs. Q6: Is the TCL QLED Upgrade Worth 31 Cents/Inch?
Both TVs come from TCL’s 2025/2026 lineup and offer 4K resolution. The 65S55 is an LED model, while the 65Q651G adds a QLED layer. In our tracking, the Q6 costs $440, giving a $/inch of $6.77 — a 4.8% premium over the S5 (($6.77 − $6.46) / $6.46 = 0.048).
For a $20 difference, you get QLED color enhancement, but not OLED-level blacks. If your priority is screen size per dollar, the S5 remains the value pick. The Q6’s QLED advantage is real, but the price per inch still favors the S5 by a measurable margin.
The S5 Against the Full 4K Market Floor
The overall 4K LED price floor — the cheapest in-stock TV regardless of size — belongs to a Westinghouse 58-inch 4K Xumo TV at $190, which works out to $3.28 per inch ($190 ÷ 58 = $3.276, rounded $3.28). That floor is set by a smaller screen, so it doesn’t help a buyer who needs 65 inches.
For 65-inch TVs specifically, the S5’s $6.46/inch is the floor. No other 65-inch model in our data — LED, QLED, or OLED — is cheaper.
To see how the S5 fits into the broader 4K LED market, here are the five cheapest 4K LED TVs per inch right now:
