Dell S3225QC Review (2026): Lab Data, Real Price & the Warranty Catch

Quick Answer: The Dell S3225QC (Dell 32 Plus 4K QD-OLED) is a flat 31.6-inch 4K 120Hz QD-OLED that reviewers rate highly for mixed work and media: Tom’s Hardware gave it 4.5/5 and an Editor’s Choice, and RTINGS measured 5.9 ms of input lag at 120Hz and 945 nits on a 2% HDR highlight. Among the 32-inch 4K OLEDs we compared, it is the cheapest with 90W USB-C, and it adds 25W of built-in speakers, but it has no DisplayPort and stops at 120Hz. Dell.com listed it at $799.99 on November 5, 2026, $300 above the $499.99 it sold for in June 2026, and the product page now shows a 1-year warranty with no burn-in wording. Buy it at $600 or less; at $799.99, Dell’s own $699.99 Alienware AW3226Q is the better deal.

The S3225QC has not had a page on this site before, even though it is one of the most-reviewed 32-inch OLEDs of the past two years. This review is built on published lab measurements, not on our own testing: RTINGS, Tom’s Hardware, PCWorld, ITPro and Wired all measured it, so every number below names the outlet that produced it. Prices and warranty terms were checked on Dell.com and other US retailers on November 5, 2026, and the price history comes from archived copies of Dell’s product page.

Dell S3225QC specs at a glance

Specs are from Dell’s US product page and the S3225QC User’s Guide (revision A04, May 2026). Where the two disagree, for example on the length of the bundled USB-C cable, we used the user guide.

Dell 32 Plus 4K QD-OLED (S3225QC)

Dell announced the S3225QC at CES on January 6, 2025, and it went on sale worldwide on May 22, 2025. The press release put the US price at $799.99, but an archived copy of Dell’s store from May 24, 2025 shows $849.99. Since then the price has moved a lot, and the cheapest Dell price we found came only five months ago:

In other words, the S3225QC cost 60% more on Dell.com on November 5, 2026 than it did on June 3, 2026. Other stores have gone lower still: Slickdeals recorded it at $449.99 for Costco members online on February 5, 2026 (an offer that ran through February 15) and at $499.99 in a California Costco store on December 7, 2025. Newegg’s listing showed it “from $472.99” the same day, but only through a third-party marketplace seller; check who the seller is before buying, because a gray-market unit can complicate a warranty claim. With Black Friday three weeks away, $600 or less is the realistic target. Our monitor deals guide covers which sale windows move monitor prices most.

What the labs measured

Five outlets published measurements and several more published verdicts. RTINGS now puts its measurements behind a membership, so the RTINGS figures below come from the archived copy of its review dated November 4, 2025 (test bench 2.1, firmware M3C104).

The measured numbers line up closely across outlets:

Three results stand out. First, input lag: RTINGS’ 11.4 ms at 60Hz is lower than the 15.0 ms it measured on the Alienware AW3225QF, which matters for 60 fps console games. Second, color accuracy depends on the mode: PCWorld measured a 0.55 average Delta E, ITPro measured 1.26 in the Standard mode and about 0.5 in the Creator modes, while RTINGS’ sRGB-mode result was 2.46. Third, HDR highlights are modest once they grow beyond a small window: PCWorld measured 430 nits on a 10% window, against 731 nits for the LG UltraGear 32GS95UE and 779 nits for the Samsung Odyssey OLED G8 in the same chart.

RTINGS still lists the S3225QC as the “Best Upper Mid-Range 120Hz Monitor”, but it dropped the monitor from its best 32-inch list on October 28, 2026 (replaced by the TCL 32R84) and from its PS5 list on July 22, 2026, where the Alienware AW2725Q took its place for lower input lag.

The weak spots

• No DisplayPort. Windows Central called the port selection a “severe lack of ports”: one HDMI 2.1, one USB-C video input, two small USB-C downstream ports and nothing else. There is no USB-A, no headphone jack and no KVM switch.
• USB-C needs DSC for 4K 120Hz. Dell’s user guide says 4K 120Hz over USB-C uses Display Stream Compression; with DSC off, USB-C is limited to 4K 60Hz. RTINGS found no option to turn DSC off.
• 120Hz is the ceiling. Every other current 32-inch 4K OLED in the table below runs 165Hz or 240Hz. Tom’s Hardware lists “only 120 Hz” among its cons.
• Purple-tinted blacks in a bright room. RTINGS measured a 3.05-nit black level under 1,000 lux of light and described the blacks as purple, a QD-OLED trait. RTINGS classifies the coating as glossy (Dell calls it anti-reflection); our matte vs glossy monitor guide explains the trade-off.
• Color fringing on text. RTINGS scored text clarity 8.5 and noted fringing from QD-OLED’s triangular subpixel layout. At 140 PPI it is minor, but people who read code all day notice it; see QD-OLED vs WOLED.
• Coil whine at high brightness. ITPro heard an audible buzz with brightness at 75% or higher and more than half the screen white. No other outlet reported it.

PS5, Xbox and Mac: what works

RTINGS checked the S3225QC with consoles and a Mac, and the results are mostly good:

For a console-only setup, the 60Hz input lag result makes it a good fit; see our best gaming monitor for PS5 ranking for alternatives with two HDMI 2.1 ports. For a laptop desk, the 90W USB-C port is the main reason to choose the S3225QC over the Alienware models, which cannot charge a laptop; our best monitor for MacBook Pro guide covers the other one-cable options.

Warranty and burn-in: what changed in 2026

This is the biggest change since the reviews were written. Windows Central and Wirecutter reported a 3-year warranty that covered burn-in, and archived copies of Dell’s US product page from September 2025 to September 9, 2026 listed a “3 Year Limited Hardware and Advanced Exchanged Service” warranty. On November 5, 2026, the same page listed “1 Year Limited Hardware and Advanced Exchanged Service”, and an archived copy from October 7, 2026 already showed 1 year. Neither the current page, the older copies nor the user guide uses the word burn-in.

What the page does still include is Premium Panel Exchange, which replaces the monitor during the warranty “even if only one bright pixel is found”, and Advanced Exchange, which ships a replacement in one to two business days. On the panel-care side, the user guide says Pixel Refresh runs automatically once accumulated use passes 4 hours, when the monitor goes to standby or is switched off, and takes 6 to 8 minutes. An OLED Panel Health indicator in the menu turns red after 7,000 hours without a refresh.

There is also no long-term burn-in data. RTINGS put the S3225QC in its Longevity 3.0 burn-in test but removed it on October 6, 2026 because the unit “wasn’t responding to HDMI commands”, so it cannot be compared with the other QD-OLEDs in that test. Our OLED burn-in guide explains what the risk looks like in practice.

The comparison matters: on the same day, Dell listed a 3-year warranty “including coverage for OLED burn in” on the Alienware AW3225QF and AW3226Q, and MSI’s datasheets list 3 years including burn-in for the MAG 321UP and MPG 321URX. If the warranty is decisive for you, check the terms shown in the cart before ordering.

S3225QC vs the 32-inch 4K OLED rivals

The S3225QC’s value case was always price. At $799.99 that case is gone: several faster OLEDs cost less on November 5, 2026.

Rival prices were checked on the retailer named on November 5, 2026; Best Buy blocked automated price checks that day. The most awkward comparison is Dell’s own: the Alienware AW3226Q is $100 cheaper, runs at 165Hz, has a DisplayPort input and carries a 3-year burn-in warranty. Its RGB-stripe subpixels also avoid the text fringing that QD-OLED shows. What it gives up is the S3225QC’s 90W USB-C and built-in speakers. The MSI MPG 321URX is $60 more and matches the S3225QC’s 90W USB-C while doubling the refresh rate; our MSI MPG 321URX review covers it.

RTINGS suggests the UltraSharp U3225QE for work-only use because an IPS panel carries no burn-in risk, and the 27-inch S2725QC for sharper text at less than half the price. Our OLED vs IPS monitor comparison explains that trade-off.

Firmware and the “Dell S 32” rename

Dell’s support site lists one current firmware for the S3225QC: M3C107, released April 13, 2026, marked optional, with one listed change, “Update model name to ‘Dell S’”. RTINGS reviewed the monitor on M3C104. A third-party firmware tracker (firmwatch.io) lists M3C106 from March 6, 2026 with the note “Matching firmware for updated camera module”. The S3225QC has a position sensor for its head-tracking spatial audio, which Dell staff have said is not a webcam.

The rename explains why the monitor is hard to find on Dell.com: the US store now lists it as the Dell S 32 4K USB-C Monitor (S3225QC), while its spec table still says 32 Plus 4K QD-OLED. Nothing in the hardware changed. Dell support staff recommend running firmware updates with the standalone updater rather than through the Dell Display and Peripheral Manager app.

Who should buy the S3225QC

• Buy it at $600 or less if you want one flat 32-inch 4K OLED for laptop work, streaming and console games, with 90W USB-C and speakers built in.
• Buy it for a PS5 or Xbox at 4K 120Hz: RTINGS’ 11.4 ms at 60Hz beats the AW3225QF’s 15.0 ms.
• Skip it at $799.99: the AW3226Q costs $100 less with a faster panel and a burn-in warranty.
• Skip it for competitive PC gaming; any 240Hz QD-OLED, such as the AW3225QF, is a better fit.
• Skip it if you run static spreadsheets or code for many hours a day: OLED burn-in risk plus a 1-year warranty is a poor combination. An IPS panel such as the U3225QE is safer.

S3225QC by the numbers

• $300. The gap between Dell’s $499.99 price on June 3, 2026 and its $799.99 price on November 5, 2026.
• 1 year. The warranty on Dell’s US page in November 2026, down from 3 years through September 9, 2026.
• 5.9 ms. RTINGS’ input lag at 120Hz; 11.4 ms at 60Hz.
• 945 nits. RTINGS’ 2% window HDR peak; 430 nits on a 10% window.
• 90W. USB-C laptop charging, which neither Alienware 32-inch OLED offers.
• 25W. Five 5W speakers, which Tom’s Hardware, Windows Central, TechRadar and Wired praised.
• 0 recalls. The CPSC recall database lists no recall for the S3225QC.

The bottom line

The Dell S3225QC remains one of the best all-round 32-inch 4K OLEDs for a desk that mixes laptop work, video and console games: most reviewers praise its picture, speakers and low input lag, and RTINGS still calls it the best upper mid-range 120Hz monitor. What changed in 2026 is the deal around it. Dell’s US page now lists $799.99 and a 1-year warranty, while the same company sells the faster AW3226Q with a 3-year burn-in warranty for $699.99. At $500 to $600 the S3225QC is a strong buy; at $799.99 it is not.
