31.5" 1500R curved gaming monitor

The Acer Nitro ED320QR S3biipx is a 31.5 inch curved display built for fast-paced gaming. Its 1500R curvature wraps the field of view for deeper immersion in competitive titles. The Full HD 1920 x 1080 panel targets players who prioritise high frame rates over pixel density. It suits setups where graphics output matches 1080p performance targets.

165Hz refresh rate and 1ms response

A 165Hz refresh rate shortens frame rendering time and lowers input lag for ultra-smooth 2D motion. The 1ms response time renders fast action and dramatic transitions without smearing or ghosting. AMD FreeSync Premium synchronises the monitor's frames with the graphics card to eliminate tearing and stuttering. The 100,000,000:1 contrast ratio deepens blacks and brightens highlights for richer scene detail.

Zero-frame design and HDR readiness

The zero-frame design removes thick bezels to maximise visible screen space from edge to edge. Wide view angle technology keeps colours consistent when sharing the screen from different positions. HDR readiness enables deeper contrast levels between black and white for supported content. The monitor includes no bundled accessories or software that alter its core display behaviour.

Questions about this item

Will the 31.5" 1500R curved panel run at 165Hz through the HDMI port on my older graphics card?

The 165Hz refresh rate is achievable at Full HD 1920 x 1080; check your card's HDMI version to confirm it supports that rate at this resolution.

How can I verify the 1ms response time and AMD FreeSync Premium are active after connecting the monitor?

Enable FreeSync in the on-screen display menu and your GPU control panel, then run the built-in frame-rate overlay or a test pattern to confirm tear-free motion at 165Hz.

Which cables are included with the ED320QR S3biipx and do I need to buy a DisplayPort cable separately for 165Hz?

The box contains the curved monitor, stand, power cable and an HDMI cable; a DisplayPort cable is not included and must be purchased separately if required.
