When I look at my collection of computer monitor reviews from the past 13 years, I see a tremendous number of displays from manufacturers that begin with the letter A. But there are lesser-represented companies with the same level of engineering expertise and high quality as mainstream brands when it comes to the best gaming monitors.
If you’re old enough to remember CRTs, then you’ve heard of the Sony Trinitron tube. This was an evolved display with a cylindrical shape rather than the bubble screens that fronted other CRTs. It wasn’t completely flat, but it curved only along one axis. And it was coveted by users for its sharp and undistorted image.
Today, you can still buy a premium gaming monitor from Sony, and here is its latest: the INZONE M10S II. It’s a 27-inch OLED with QHD resolution and 540 Hz refresh rate. It runs at 720 Hz in HD and supports Adaptive-Sync, HDR, and wide-gamut color. Let’s take a look.
The M10S II starts with an OLED panel that runs natively at 2560x1440 QHD resolution and 540 Hz. A dual-refresh mode bumps that up to 720 Hz at HD, 1280x720 pixels. Adaptive-Sync runs on both AMD and Nvidia platforms, and you get HDR support with the ability to calibrate for HDR10 content. The screen coating is unusual in that it’s matte, while nearly every OLED that crosses my desk is shiny. That finish is extremely effective at rejecting image-spoiling ambient light. It literally swallows up reflections and displays the image without any visible grain.
The M10S II delivers a huge color gamut that, in my tests, covered nearly 110% of DCI-P3. I found that calibration was necessary, but the reward was a beautifully saturated image. There’s an sRGB mode available if you need that smaller gamut for photography or graphics work. You also get variable brightness to stretch dynamic range. It has two settings that had a positive impact in both practice and testing. I’ll tell you more about that on page four. Peak output is around 475 nits in SDR mode and 543 nits in HDR mode when measuring a 25% window pattern.
For gaming, you get plenty of goodness in the form of static and dynamic aiming points, OLED anti-flicker, black frame insertion for blur reduction at low frame rates, an FPS indicator, and a set of timers. Missing are internal speakers and LED lighting, but you do get USB ports for peripherals. There’s panel protection in the form of advanced heat management and OLED care options, such as panel refresh and pixel orbiting. The latest I/O ports also include one DisplayPort 2.1 and two HDMI 2.1 ports. A pair of headphones can be plugged into the provided 3.5mm jack. There’s a comprehensive OSD for control, or you can use Sony’s INZONE Hub app, which is free to download.
The M10S II sells for $1,100 at this writing, so it’s primed to compete with other speedy competition displays. While it isn’t quite as loaded as an Asus ROG Swift screen, it delivers equal performance and image quality.
