The cheapest 65-inch Vizio QLED, the M65Q6‑L4, costs $378 ($5.82 per inch). The cheapest TCL 65-inch QLED, the 65Q651G, costs $440.22 ($6.77 per inch).
The Short Answer
Vizio’s only tracked 65‑inch QLED — the M65Q6‑L4 — wins at $5.82 per inch, undercutting the cheapest TCL 65‑inch QLED, the 65Q651G, at $6.77 per inch. That’s a 14.1% lower cost per inch, delivering a clear victory for budget‑first buyers who need a 65‑inch screen.
Price Per Inch Breakdown
Both prices come directly from the lowest in‑stock listings tracked across major US retailers as of May 4, 2026. Here’s the math:
- Vizio M65Q6‑L4 — $378 ÷ 65 inch = $5.82/inch (exact: $5.815385). Sold by Amazon.
- TCL 65Q651G (Q6 Class) — $440.22 ÷ 65 inch = $6.77/inch (exact: $6.772615). Sold by Newegg.
The per‑inch gap is $0.95 ($6.772615 – $5.815385), making Vizio 14.1% cheaper than TCL:
($6.772615 – $5.815385) ÷ $6.772615 = 14.1%.
These are live floor prices — the cheapest in‑stock listing for each exact model. We do not use averages, MSRPs, or historical sale prices. This ensures you’re seeing the true cost per inch you’d pay today.
Same Size, Same Technology?
Yes — both are 65‑inch QLED 4K TVs, so we’re comparing identical screen technologies at the same diagonal. The Vizio listing explicitly confirms Dolby Vision and 120fps @1080p PC gaming support, plus Wi‑Fi 6 and Bluetooth headphone capability. The TCL 65Q651G’s title mentions HDR but not Dolby Vision; it does state “Smart Google TV,” confirming the built‑in Google TV operating system. No other HDR format or backlight detail is named in our live tracking data for either model, so we won’t guess.
Feature parity holds where it counts: two 65‑inch 4K QLED panels with smart platforms, each pulling a floor price tens of dollars apart. The Vizio is cheaper and specifies Dolby Vision + 120fps gaming; the TCL provides Google TV out of the box. That means Vizio offers Dolby Vision and 1080p 120fps gaming for $62 less, making it the better hardware value.
What the Extra Cost Buys You
Choosing the TCL 65Q651G over the Vizio M65Q6‑L4 adds $62.22 to your purchase, or $0.95 per inch. That premium buys:
- Google TV — the TCL runs a full Google TV interface, versus Vizio’s proprietary smart platform (SmartCast / Vizio Home, as implied by the listing).
- No further objective differentiator that our tracking can confirm. Both are QLED 4K panels; neither lists additional hardware features such as HDMI 2.1 ports, VRR, or Mini‑LED backlights in their product titles.
We never invent specs — a “Dolby Atmos” claim for the TCL is absent from our verified DB sources, so we leave it out. If integrated audio or a specific OS experience matters, that may tip the scale, but on pure hardware features the Vizio’s Dolby Vision and 120fps gaming spec stand out.
When Each Makes Sense
- Pick the Vizio M65Q6‑L4 if you want the absolute lowest cost per inch on a 65‑inch QLED. Just be ready for the Vizio smart platform.
- You’ll get a QLED 4K set, but not the Dolby Vision or 120fps gaming label confirmed for Vizio.
Verdict
Vizio wins on pure price per inch for a 65‑inch QLED: $5.82 versus TCL’s $6.77. All figures are the cheapest tracked listings active on May 4, 2026. With a $62.22 lower price, Dolby Vision, and 1080p 120fps gaming, the Vizio M65Q6‑L4 is the standout budget pick. If per‑inch cost matters most, Vizio takes the crown.
