Sony INZONE M10S II 540Hz OLED Gaming Monitor Test
This text is an excerpt from a detailed review of the Sony INZONE M10S II monitor, focusing heavily on its color accuracy, HDR performance, and overall quality compared to other monitors.
Here is a structured summary of the key findings:
Color and Calibration Accuracy
Out-of-Box Issues: The monitor’s default grayscale setting was clearly blue in tone. An initial measurement showed a 6.17dE error, which was improved to around 3dE by adjusting the color temperature.
Calibration Benefit: The reviewer strongly recommends calibration, which brings the error down to 1.51dE, resulting in no visible issues.
Game Mode vs. Standard Mode: The “Game” mode mode pulls the color gamut off target, causing visible hue errors (e.g., yellow appearing too green, magenta too blue). Switching to Standard picture mode with a Warm color temperature provides a more natural and accurate result.
Gamut Testing: Using Portrait Displays’ Calman software, the monitor performs well, with the sRGB average error being 1.34 dE. It covers nearly ideal coverage in the volume test, achieving 96.61% sRGB coverage and utilizing almost 110% of the DCI-P3 color space.
HDR Performance
Luminance and Contrast: The brightest HDR picture mode (Game mode) reaches over 543 nits, delivering punchy images with deep shadows and sharp highlights.
Grayscale and EOTF: In the grayscale and EOTF tests, the monitor performed accurately. It tracked very closely to the reference with a correct tone-map transition at 68% brightness.
Color Fidelity: While the color is vibrant, there is some oversaturation in red, and slight deviations in yellow and magenta were noted. It performs well in the BT.2020 space, with coverage measured at 90% red, 80% green, and 98% blue.
Overall HDR Takeaway: The monitor has superb HDR luminance and grayscale tracking. Despite some oversaturation, it fills more of the color space than many competitors, making it suitable for color-critical work.
Performance and Conclusion
Comparison: Despite not being at the absolute top tier, the M10S II has no visible errors once calibrated and performs on par with other premium OLED displays.
Gaming Features: The monitor offers high performance, including a 540 Hz refresh rate at QHD resolution, along with other flexible modes (like 720 Hz at HD and two 24.5-inch modes).
Final Verdict: The review concludes that the M10S II is a powerful monitor. Competitors seeking the fastest and most flexible OLED display should consider it, especially if they have the budget.
Overall Test Takeaway: The M10S II requires a few adjustments in the On-Screen Display (OSD) or calibration settings (Standard mode with Warm color temp) to achieve its best picture quality, but it delivers excellent performance in terms of color accuracy and HDR brightness.
