Acer AOpen 32S1UPRO 31.5" 4K Monitor

The Acer AOpen 32S1UPRO is a 31.5 inch 4K UHD monitor with a Vertical Alignment panel and LED backlight. It delivers a 3840 x 2160 resolution at 60 Hz with 350 nits brightness and 16.7 million colours. The gold-finished display includes integrated 2.0 channel speakers and offers HDMI, USB, and USB Type-C connectivity. Height and swivel adjustments provide ergonomic flexibility for professional workspaces.

Suited for colour-critical tasks

The 95% DCI-P3 colour gamut and 3,000:1 native contrast ratio serve creative professionals editing photos or video. Office users benefit from the large 31.5 inch canvas and wide 178° viewing angles for shared viewing. Buyers needing high refresh rates for competitive gaming or fast motion clarity should look elsewhere due to the 60 Hz limit and 21 ms response time. The single mini HDMI port may also restrict multi-device setups requiring multiple full-size HDMI inputs.

60 Hz refresh rate and 21 ms response time

This monitor operates at a fixed 60 Hz vertical frequency with a 21 ms response time. That specification defines its suitability for static content, office applications, and colour-accurate creative work. It excludes the display from high-frame-rate gaming, rapid motion video, or any workflow demanding faster pixel transitions. Verify that your source device and cable support 3840 x 2160 at 60 Hz over the available HDMI or USB Type-C interfaces.

Questions about this item

Should I pick the 31.5-inch 4K UHD model or a smaller screen?

The 31.5-inch VA panel delivers 3840 x 2160 resolution at 60 Hz with 95% DCI-P3 coverage and 350 nits brightness, giving sharp detail and wide colour for creative work or media.

What does the 21 ms response time feel like in daily use?

At 21 ms grey-to-grey the panel suits office tasks, video playback and casual browsing; fast-paced gaming may show noticeable motion blur compared to quicker IPS or TN screens.

Which ports limit the 4K 60 Hz signal on this monitor?

The mini HDMI and USB Type-C inputs both support 3840 x 2160 at 60 Hz, so either connection can drive the native resolution and refresh rate without bandwidth bottlenecks.
