Our take
I’ve been using the Sony INZONE M9 for competitive gaming, and the 144Hz refresh rate combined with 1ms response time makes motion incredibly smooth. The 4K resolution is crisp, and local dimming helps with HDR content. Colors are vibrant on the IPS panel, though the 400 cd/m² brightness could be higher for brighter rooms. The inclusion of HDMI 2.1 and USB-C is a plus for modern consoles and laptops. Overall, a solid high-refresh-rate 4K monitor for gaming, but be aware that contrast is typical IPS.
