Our take
The Sony INZONE M9 delivers a premium 4K gaming experience. The 27-inch screen size is ideal for desk setups, and the 144Hz refresh rate makes motion incredibly smooth. Response time at 1ms eliminates ghosting. Input lag is low thanks to HDMI 2.1. The build feels premium, and the display is VESA compatible. On the downside, the 1000:1 contrast ratio is typical for IPS, so blacks aren't as deep as OLED. At $500, it's priced competitively for its specs. If you're building a high-end gaming rig, this is a solid choice.
