Speed with style

Leave lag in the dust: The 1ms response time and 144Hz refresh rate deliver a smooth, uninterrupted experience. Rapid pixel color changes eliminate motion blur and keep you in the middle of the action.

Stutter-free: NVIDIA G-SYNC Compatible Certification and AMD FreeSync™ Premium technology adds another layer of seamless gameplay by eliminating screen tearing and stuttering.

Get lost in the view: Play in Full HD resolution and experience sharp, detailed visuals that take you deeper into the game.

Full throttle thrills. Bold new look.

If looks could kill: The new, bold design means your monitor looks as good as it performs. A 3-sided narrow bezel creates expansive views, plus unique vents located in the back keep everything cool while working hard.

More room for battle: The newly designed tapered stand is slim and sleek, with a small footprint that brings you closer to the action.

Refined by you

Customize every advantage: Three user-defined profiles give even more personalization options. The Timer, FPS Counter and Dark Stabilizer let you manage everything from frame rates to brightness to shadow control.

Gaming-centric tools: Easily navigate and manage the OSD menus with new joystick and shortcut buttons located on the back of the monitor.

Bends to your will: The height- and tilt-adjustability lets you game in comfort for extended periods.
