Pros & Cons

Pros

  • ✓ 31.5-inch WQHD panel at 0.272mm pixel pitch keeps 1440p text sharp
  • ✓ 180Hz over DisplayPort 1.4 for high-frame-rate competitive play
  • ✓ 1500R curve puts screen corners equidistant from your eyes
  • ✓ AMD FreeSync removes tearing without an extra G-Sync module cost

Cons

  • ✗ HDMI 2.0 ports cap at 144Hz - DisplayPort needed for full 180Hz

  • ✗ 2W speakers are a stopgap; plan on headphones or desk speakers

Manufacturer description

The Acer Nitro EDA323QU S3bmiiphx gives you a 31.5-inch curved gaming panel at WQHD 2560 x 1440, and it does it at a size most 1440p monitors reserve for 27-inch class pricing. The 1500R curve keeps every corner of the 16:9 screen roughly equidistant from your eyes, which cuts the edge-distortion you get on flat ultrawides and removes blind spots during long sessions. Refresh tops out at 180Hz over DisplayPort 1.4 and 144Hz over either HDMI 2.0 port, with 1ms VRB response and AMD FreeSync syncing panel frames to your GPU so tearing and stutter drop out of fast-motion scenes.

Frequently Asked Questions

Can the Acer Nitro EDA323QU really hit 180Hz?

Yes, but only over DisplayPort 1.4. Both HDMI 2.0 ports top out at 144Hz, so use the DisplayPort input for the full 180Hz refresh rate.

Is 1440p sharp enough on a 31.5-inch screen?

Pixel pitch is 0.272mm at 2560 x 1440 across 31.5 inches. That is noticeably finer than a 1080p panel of the same size, and it reads cleanly at a typical 2.5 to 3 foot desk distance.

Does it work with an NVIDIA graphics card?

The monitor is built around AMD FreeSync for adaptive sync. NVIDIA cards can drive it at 180Hz over DisplayPort; check Acer's listing for G-Sync Compatible certification status before relying on variable refresh with GeForce.

Can I wall-mount or arm-mount this monitor?

Yes. It is VESA mounting compliant at 100 x 100mm. The included stand offers tilt only, from -5 to 20 degrees, so an arm is the practical route if you need height or swivel adjustment.

What cables and ports does it come with?

It has one DisplayPort 1.4, two HDMI 2.0 ports, and one audio out. An HDMI cable is included in the box; buy a DisplayPort cable separately if you want the full 180Hz.

Key Features

  • Quality Visuals: The EDA323QU 31.5" gaming monitor with 2560 x 1440 WQHD resolution in a 16:9 aspect ratio presents stunning, high-quality images with excellent detail.

  • AMD FreeSync Technology: Say “goodbye” to stuttering and tearing. With AMD FreeSync, the monitor’s frames are synced with the graphics card’s frames, which eliminates screen tearing and provide the smoothest gaming experience.
  • Quick Refresh Rate: The 180Hz refresh rate speeds up the frames per second to deliver an ultra-smooth 2D motion scene. With a rapid refresh rate of up to 180Hz, Acer Monitors shorten the time it takes for frame rendering, lower input lag and provide gamers an excellent in-game experience.
  • Responsive: Fast response time of 1ms 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.
  • ZeroFrame Design: With a EDA323QU monitor, you’ll want to see as much of the display as possible. Get more monitor real estate with the near bezel-less design, allowing you to see more and do more. The ZeroFrame design lets you place multiple monitors next to each other for a seamless, almost uninterrupted view.
  • Curved Screen: The curved 16:9 display wraps you in a world of entertainment with every corner of the screen at the same distance from your eyes for a uniform viewing experience without blind spots. Tilt the screen -5 to 20 degrees for the most comfortable view.
