Sony 27 INZONE M3 Full HD HDR 240Hz Gaming Monitor - Fast Competitive

Our review of the Sony 27 INZONE M3 finds it best suited for competitive gamers and console owners who prioritize smooth motion and accurate color. The monitor's standout is its 240Hz refresh rate and 1ms GTG response, which deliver extremely responsive inputs and fluid gameplay. Combined with DisplayHDR 400 and over 99% sRGB coverage, it provides vivid, consistent color for fast-paced titles and media playback while also offering practical features like a built-in KVM switch and PlayStation 5 enhancements.

Key Features

• 240Hz refresh rate: Ultra-fast refresh keeps motion crisp and reduces motion blur during competitive play for a clear advantage.
• 1ms GTG response: Lightning-fast pixel response helps minimize ghosting so fast-moving targets remain visible.
• HDR 400 and wide sRGB: DisplayHDR 400 and over 99% sRGB coverage deliver brighter highlights and richer colors for more lifelike visuals.
• Nvidia G-SYNC and HDMI 2.1 VRR: Variable refresh compatibility reduces tearing and stuttering across modern GPUs and consoles.
• Built-in KVM switch: Control two PCs with a single keyboard, mouse and headset, simplifying multi-system setups without swapping peripherals.
• PS5 features and inputs: Auto HDR Tone Mapping and Auto Genre Picture Mode plus HDMI 2.1 ports and USB-C make it console-ready and versatile.

Who It's For

The INZONE M3 is aimed at PC and console players who need a high refresh rate and accurate color in a 27 in package: esports players, streamers, and anyone who values the immediate feel of inputs and reduced visual tearing. The HDMI 2.1 and G-SYNC support also makes it a natural pick for PlayStation 5 owners who want Auto HDR Tone Mapping and VRR.

Those who place the highest priority on extreme brightness, 4K resolution, or perfect out-of-the-box reliability for every unit should consider other models if HDR peak luminance above 400 nits or higher resolution is essential. Some buyers have also reported inconsistent units, so shoppers who need guaranteed flawless hardware may prefer retailers with strong return policies.
