About this item

  • Quality Visuals: The KG271U 27" IPS monitor with 2560 x 1440 WQHD resolution in a 16:9 aspect ratio presents stunning, high-quality images with excellent detail. The zero-frame design does away with the thick frames found on conventional monitors freeing up precious screen space.
  • AMD FreeSync Premium Technology: Say “goodbye” to stuttering and tearing. With AMD FreeSync Premium, the monitor’s frames are synced with the graphics card’s frames, which eliminates screen tearing and provides the smoothest gaming experience.
  • Up to 275Hz Refresh Rate: The 275Hz refresh rate speeds up the frames per second to deliver an ultra-smooth 2D motion scene. With a rapid refresh rate of up to 275Hz, Acer Gaming Monitors shorten the time it takes for frame rendering, lower input lag and provide gamers an excellent in-game experience.
  • Goodbye Ghosting: Up to 0.5ms GTG (Gray to Gray) response time enhanced gamers’ in-game experience. No matter the fast-moving action or any dramatic transitions will be all rendered smoothly without the annoying effects of smearing or ghosting with KG271U Gaming Monitor.

    Solid choice upgrading from an older monitor.

    I didn't want to spend an astronomical amount on a new one after mine was damaged in a move. This is a significant upgrade over my old HP Omen monitor. Kind of expected with it being 10 years newer. I'm a casual gamer. I play a lot of FPS and RPGs on PS5. The response time is nuts. Maybe a hard-core gamer could pick it apart more and doesn'thave the specs of the Alienware? My only real complaints are the stand seems flimsy. The monitor can rock side to side a bit more than I'd like. And the volume has one lever. Loud AF. Turning it down on the monitor itself doesn't work nor does turning it do

    1440 perfection

    Awesome display. Love the little joystick to move around menus. Darn near a perfect 1440 monitor.
