The cheapest 50-inch 4K QLED TV per inch right now is the VIZIO VQD50M at $194 ($3.88/inch), undercutting the TCL 50S5K at $373 ($7.46/inch). That’s a 48% lower cost per inch for the Vizio — a clear win for screen-size shoppers on a budget.
The Short Answer
Vizio wins the 50-inch price-per-inch battle by a wide margin. The VIZIO VQD50M rings in at $194 for 50 inches, or exactly $3.88 per inch — the cheapest QLED in its size class that we track. The closest TCL 50-inch, the TCL 50S5K, costs $373, pushing its cost to $7.46 per inch. That means Vizio is 48% cheaper per inch than TCL for a 50-inch QLED 4K TV. If you’re buying strictly on screen area, the numbers don’t lie.
Price Per Inch Breakdown
| Product | Price | Size | $/Inch | Retailer |
|---|---|---|---|---|
| VIZIO VQD50M 50 inch Class Quantum 4K QLED UHD HDR Smart TV | $194 | 50″ | $3.88 | amazon |
| TCL 50S5K Television 50 Inch Smart TV QLED HDR 10 Google TV | $373 | 50″ | $7.46 | amazon |
Both are in-stock 50-inch 4K QLED models as of our latest scrape. The Vizio at $194 gives $194 ÷ 50 = $3.88/inch; the TCL at $373 gives $373 ÷ 50 = $7.46/inch. The percentage gap is enormous because the Vizio starts nearly $180 lower upfront while holding the same screen diagonal.
Same Size, Same Tier?
This is an apples-to-apples QLED-vs-QLED showdown. The Vizio listing does not specify HDR format beyond “HDR,” while the TCL explicitly says “HDR 10.” Neither title mentions 120Hz, Full Array Local Dimming, or HDMI 2.1 — and we only report what the listings state. So at the listing-level spec sheet, you’re getting the same core display technology and resolution from both brands. The $179 premium on the TCL does not buy a size advantage or a step up to OLED; it stays in the same QLED lane.
What the Extra Cost Buys You
Based on each product’s official title:
- VIZIO VQD50M: “50 inch Class Quantum 4K QLED UHD HDR Smart TV” — confirms Quantum Dots, 4K resolution, and HDR capability.
- TCL 50S5K: “Television 50 Inch Smart TV QLED HDR 10 Google TV” — adds HDR10 branding and Google TV.
Neither title names a specific refresh rate, local dimming zone count, or voice assistant.
When Each Makes Sense
- Choose the VIZIO VQD50M if your only metric is getting the most 4K QLED screen for the least money. At $194 and $3.88/inch, it’s the cheapest 50-inch QLED in our tracking, period.
- Choose the TCL 50S5K if you must have Google TV built in (no external streamer) and prefer a TV that calls out HDR10 in its spec sheet — but accept that you’ll pay $179 more for the same 50-inch QLED panel space.
Verdict
For anyone asking “What’s the cheapest 50-inch 4K TV per inch today,” the Vizio VQD50M is the answer at $3.88/inch against TCL’s $7.46/inch. We’d only look at the TCL 50S5K if Google TV or explicit HDR10 branding outweigh a nearly double per-inch cost. Prices checked May 10, 2026.
Frequently Asked Questions
Is the Vizio VQD50M worth it over the TCL 50S5K for pure value?
Yes — the Vizio delivers 48% lower cost per inch. You’re buying the same 50-inch QLED screen size for $179 less. Unless the TCL’s Google TV or HDR10 branding is essential, the Vizio is the textbook budget play.
Does TCL have a 50-inch 4K TV cheaper than $373?
Our live tracking currently shows the TCL 50S5K as the only 50-inch TCL QLED in stock at $373 / $7.46/inch. We monitor prices daily, and if a lower-priced TCL 50-inch appears, the numbers will update — but right now, Vizio’s VQD50M is untouchable on cost per inch.
Are there any 50-inch TVs cheaper than $3.88 per inch in May 2026?
Not in the QLED 4K class. The category floor for 4K QLED is exactly $3.88/inch, set by the Vizio VQD50M. You could dip into LED models (the floor for all 4K LED TVs is $3.2757/inch across all sizes), but for a 50-inch QLED specifically, this Vizio is the cheapest we track.
Which brand offers better picture quality for 50-inch 4K TVs: Vizio or TCL?
We can’t make subjective picture assessments without test data. Both models are QLED panels with at least baseline HDR. The Vizio VQD50M’s listing mentions only “HDR,” while the TCL 50S5K specifies HDR10. Beyond that, the value gap — $194 vs $373 — means you can put the savings toward a soundbar or calibration disc without losing any screen acreage.
