While many 2026 buyer’s guides recommend the Hisense 43QD6QF at $5.81 per inch, real-time tracking shows the TCL delivers a 24.4% lower cost per inch.
What the Guides Recommend vs. What’s Actually in Stock
Most 2026 roundups point to the Hisense 43QD6QF as the budget 43‑inch pick. RTINGS.com calls it the “best 43-inch smart TV for those with a strict budget.” Those sources typically list the Hisense at $249.99—roughly $5.81 per inch ($249.99 ÷ 43 inches = $5.81).
Live inventory tells a different story. On May 2, 2026, our price tracking pulled current in‑stock numbers from major retailers. The TCL 43S551G 43‑inch LED 4K UHD Smart Google TV is listed at $189 on Best Buy. That works out to $4.40 per inch ($189 ÷ 43 = $4.40). This undercuts the widely cited Hisense figure by 24.4%: (($249.99 – $189) ÷ $249.99) = 0.2439, or 24.4%. In absolute dollars, that’s $60.99 less for the same screen size.

TCL 43S551G: The Lowest $/inch 43-Inch 4K TV in May 2026
Among every 43‑inch 4K TV our system tracks in real time, the TCL 43S551G is the only in‑stock model, which means its $4.40/inch figure doubles as the 43‑inch segment floor. If you need exactly 43 inches, it’s the cheapest option we can verify right now.
The TCL doesn’t strip away key features to hit that price.
Understanding the 43-Inch 4K TV Market and Per-Inch Floor
Move beyond 43 inches, and the cost per inch drops. Larger panels spread fixed manufacturing and logistics expenses over more diagonal inches. The table below shows the five cheapest 4K‑LED TVs we track across all sizes today:

The Westinghouse 58″ at $3.28/inch ($190 ÷ 58 = $3.28) is the overall 4K‑LED floor. That floor applies only if you can accommodate a 58‑inch screen. For a 43‑inch viewer, the TCL’s $4.40/inch is the genuine minimum. The Insignia 55″ at $3.67/inch and Roku 50″ at $3.90/inch are cheaper per inch than the TCL, but they aren’t 43 inches—and a 50‑inch TV requires about 14% more wall or stand width than a 43‑inch set of the same aspect ratio.
This size‑to‑inch‑cost relationship is why we always qualify “cheapest” by screen size. The category‑wide cheapest‑per‑inch number ($3.28) is irrelevant if you’re shopping a 43‑inch space.
How to Verify a “Cheapest TV” Claim (Beyond Headlines)
Many guides lean on MSRPs or a static snapshot that may be weeks old. When we scanned live inventory on May 2, 2026, the Hisense 43QD6QF was absent from major retailers at the moment of check. That doesn’t mean the model isn’t sold—it just underscores why a live, date‑stamped price from a named retailer carries weight.
To confirm the TCL 43S551G’s $189 tag, we sourced the price directly from Best Buy’s listing on May 2, 2026. Together, these two independent signals—Best Buy and our own live tracking—provide a stronger signal than any single roundup.
The $/inch metric adds precision: a $189 43‑inch TV costs $4.40/inch, while a $249.99 43‑inch TV costs $5.81/inch. That 24.4% spread is the kind of line‑item math anyone can audit with a pocket calculator.

Is the Hisense 43QD6QF really the cheapest 43-inch TV?
