Sony 27” INZONE M9 4K HDR 144Hz Gaming Monitor with Full Array Local Dimming (SDM-U27M90)

Nothing stays hidden with Full Array Local Dimming contrast

With Full Array Local Dimming, light goes exactly where it’s needed so you see more depth in shadow and highlights. Spot rivals lurking in the dark and uncover objects in brightness with more clarity. Enhanced contrast across the screen opens up your view of the game like never before.

Accept nothing less than razor-sharp 4K detail

4K gaming monitors have four times more pixels than Full HD monitors. Whether you like shooting, racing or role play, you’ll enjoy flawless images with crystal-clear details and greater pixel density.

Aim accurately, shoot fast with 144Hz refresh rate

Sharpen your senses and respond fast. A refresh rate of up to 144Hz gives you that split-second advantage that makes all the difference in tracking opponents precisely.

Eliminate screen tearing with NVIDIA G-SYNC and VRR

By adjusting the display refresh rate dynamically to match the variable frame rates of gaming devices, the INZONE M9 monitor with NVIDIA G-SYNC and HDMI 2.1 Variable Refresh Rate (VRR) compatibility virtually eliminates screen tearing, stuttering and delay for smoother, more fluid gameplay.

DisplayHDR 600 certified, true visual immersion

With DisplayHDR 600, scenes are reproduced in vivid color with rich accurate contrast and high peak brightness of 600 nits. Now you can see spectacular highlights as the game creators intended.

Vibrant and realistic colors with over 95% DCI-P3 coverage

With over 95% coverage of the DCI-P3 spectrum, the INZONE M9 4K HDR gaming monitor brings out an extended range of over a billion rich, vibrant colors. More shades and hues create breathtaking scenes for immersive gaming.

Rapid action with 1ms GtG response time

Perform at a whole new level on an IPS display with ultra-fast 1ms GtG response speed. Less ghosting and blur allows you to see what’s happening with absolute clarity so you can make lightning-fast decisions and react immediately

Perfect for PlayStation 5

Pair the INZONE M9 with your PS5 console to get a fantastic gaming experience and features made specifically for PS5 consoles. With Auto HDR Tone Mapping, your INZONE gaming monitor automatically recognizes your PS5 console and optimizes HDR settings during initial setup of the console. Auto Genre Picture Mode can detect when you’re playing a game or watching movies on your PS5 console and automatically switch to the best picture quality mode.

The unique, low-depth tripod stand provides total gaming comfort while optimizing desk space for peripherals. The stand is also height and tilt adjustable to get the best viewing experience. Integrated cable management keeps your desktop clean and distraction free. Adjust the color of the rear light bar to match your room ambience.
