The Sony INZONE M10S II is a 27-inch-class QHD OLED gaming monitor built around a choice: up to 540 Hz at 2560 × 1440, or up to 720 Hz at a lower HD resolution over DisplayPort. That makes it a serious option for competitive players who prioritize refresh rate, but the headline 720 Hz figure is not available at QHD. Whether the monitor makes sense depends on which games you play, the resolution you want, and whether its premium price fits your budget.
What this review can—and cannot—establish
Sony positions the INZONE M10S II for tournament play and says it was developed with Fnatic. Its defining feature is Dual Mode: QHD at up to 540 Hz or HD at up to 720 Hz over DisplayPort. Sony also publishes OLED response-time, brightness and color figures. Those are manufacturer specifications, not independent measurements in this article.

PC Gamer’s independent review discusses the monitor’s Motion Blur Reduction feature and lists its own review specifications. That review is useful context, but the available evidence does not establish a complete, like-for-like comparison with a named competing model. So this is best viewed as an assessment of the M10S II’s strengths, trade-offs and likely audience—not a claim that it is categorically the fastest or best-value monitor in its field.

QHD at 540 Hz or HD at 720 Hz?
The dual-mode choice is the most important practical decision. QHD gives you a sharper 2560 × 1440 image while still offering a very high maximum refresh rate. The 720 Hz headline is reserved for the lower-resolution HD DFR mode, so it should not be read as a way to get 720 Hz at QHD.

QHD mode: prioritize image detail
At 27-inch class, QHD is the monitor’s native resolution and the more natural fit for players who want both high refresh and a detailed image. It is also the mode to consider if you play a mix of competitive and visually demanding games rather than treating maximum frame rate as the only goal.
HD DFR mode: prioritize refresh rate
The 720 Hz mode is for players willing to reduce resolution in pursuit of the highest refresh rate. Sony specifies that this mode is available over DisplayPort. Whether the trade-off is worthwhile depends on the games you play, your visual preferences and whether your system can deliver frame rates that make use of the mode.

HDMI has a separate ceiling
Sony lists HDMI support up to 480 Hz, below the DisplayPort maxima. If you are choosing a connection to reach the monitor’s highest stated refresh rates, check the exact port and mode requirements in Sony’s regional documentation rather than assuming every input supports every mode.

OLED, brightness and response claims
The M10S II combines an OLED panel with Sony’s published 0.02 ms GTG response-time specification. Sony also lists 335 cd/m² typical brightness, 1,500 cd/m² peak brightness and 99.5% DCI-P3 coverage. These figures describe the manufacturer’s specifications; they do not by themselves establish how the monitor performs across real scenes or under a particular test method.
Rank #3

- Noise-Isolating Sealed Design: Fully enclosed body and multiple eartip sizes block distractions for full focus on your game.

Peak brightness should not be confused with sustained full-screen brightness. PC Gamer’s review specifications distinguish 335 nits full-screen from a 1,500-nit peak HDR figure at 1% APL, a small bright-area condition. That distinction matters when interpreting an impressive peak number: it is not a promise that the whole screen maintains that brightness.
Sony lists Super Anti-Reflection Film / Super Anti-Glare treatment, and its product materials promote a custom heat sink. Confirm the exact feature names and availability on the product page for your region.

Motion Blur Reduction and competitive positioning
Sony promotes Motion Blur Reduction as a competitive-play feature. PC Gamer’s review says the feature can make 270 Hz look approximately as clear as 540 Hz. That is the publication’s assessment, not a universal result or a guarantee for every game, setting or viewer. The available evidence does not support a broader claim about its effect on image brightness, visual comfort or performance in all conditions.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsSony’s official product video describes the monitor this way: “Developed with Fnatic, and featuring Dual Mode QHD 540Hz / HD 720Hz and 0.02ms response time, the M10S II is ready for tournament play.” That is the manufacturer’s positioning. Buyers should weigh the mode choice and the features they will actually use, rather than treating tournament language as proof that the monitor is the best choice for every competitive player.

Who should consider the INZONE M10S II?
- Competitive players who want QHD and very high refresh: The QHD 540 Hz mode combines the native resolution with the monitor’s highest QHD refresh specification.
- Players who would trade resolution for refresh: The HD 720 Hz mode offers a still higher maximum, but only at lower resolution over DisplayPort.
- OLED buyers who value speed-focused specifications: Sony publishes a 0.02 ms GTG response-time figure and OLED panel specifications, while independent testing should be consulted for measured behavior.
- Buyers comparing premium monitors: The price observations place this in a premium bracket, so compare current local pricing, warranty terms, input requirements and performance at the same resolution before deciding.
It is a less obvious fit for anyone who expects 720 Hz at QHD, wants a low-cost upgrade, or needs a definitive competitive ranking against a particular rival. The available review evidence does not establish that kind of head-to-head verdict.
Price and availability
Sony UK’s product page listed the monitor at £1,199 when accessed on October 7, 2026. PC Gamer’s review, published September 22, 2026, listed $1,099 and £1,199. These are source snapshots, not assurances of current pricing, stock or availability in every country. Check a local retailer for the current price and verify the SDM-27Q102 regional SKU before ordering.
Verdict
The INZONE M10S II’s case is straightforward: OLED, QHD at up to 540 Hz, and an HD mode reaching up to 720 Hz over DisplayPort. Its key compromise is equally clear: you choose the highest refresh rate by lowering resolution. Sony’s published specifications and competitive positioning make it a notable premium monitor, but without a complete named-competitor comparison, the strongest buying decision is to judge it against your preferred resolution, connection, games and current local price.
