Acer CB342CK SMIIPPHZX 34-inch UltraWide QHD Monitor
Expand your workspace with an immersive 21:9 ultrawide display, detailed QHD resolution, IPS viewing angles and versatile connectivity for work and entertainment.
A Wider Workspace for Work and Entertainment
The Acer CB342CK SMIIPPHZX is a 34-inch ultrawide monitor designed for users who want more horizontal screen space for multitasking, productivity and entertainment. Its 3440 × 1440 UW-QHD resolution and 21:9 aspect ratio provide room for multiple windows, wide spreadsheets, editing timelines and panoramic content.
IPS panel technology supports wide viewing angles, while AMD FreeSync helps deliver smoother visuals with compatible systems. The monitor also includes HDMI and DisplayPort connectivity, a USB hub and built-in stereo speakers, making it a versatile option for a home office or workstation.
Key Features of the Acer CB342CK
34-inch UltraWide Display
The 21:9 widescreen format gives you additional horizontal workspace for side-by-side applications and wide-format content.
UW-QHD Resolution
A 3440 × 1440 resolution provides detailed images and ample room for documents, creative timelines and multitasking.
IPS Panel Technology
Wide 178-degree horizontal and vertical viewing angles help maintain a consistent view from different seating positions.
USB Hub and Stereo Audio
The built-in USB hub and 3W stereo speakers add convenience to a streamlined desk setup.
Make Multitasking More Comfortable
The 21:9 aspect ratio gives the CB342CK an advantage for workflows that benefit from a wider canvas. Keep reference material beside a document, view multiple spreadsheet columns, arrange browser windows side by side or work with a broad editing timeline without relying as heavily on multiple displays.
Its 75Hz refresh rate supports everyday desktop use with smoother motion than a conventional 60Hz display. AMD FreeSync can help reduce screen tearing with compatible graphics hardware and supported refresh-rate settings.
Detailed Visuals and Wide Viewing Angles
With 3440 × 1440 pixels across a 34-inch-class display, the Acer CB342CK provides a detailed workspace for productivity, content creation and entertainment. IPS technology offers 178-degree viewing angles, helping images remain viewable when you're not seated directly in front of the screen.
Acer lists a 1 ms Visual Response Boost (VRB) mode. This is a motion-blur reduction specification rather than a guarantee of 1 ms grey-to-grey pixel transitions in every operating mode. The monitor's 75Hz refresh rate makes it better suited to productivity and casual gaming than to competitive high-refresh-rate gaming.
Acer also describes this model as HDR-ready. With its listed 250-nit brightness for the SMIIPPHZX version, HDR capabilities should be considered entry-level rather than equivalent to the performance of a high-brightness HDR monitor.
Technical Specifications
Specifications are based primarily on Acer's official listing for part UM.CB2AA.001. Acer's pages for other CB342CK regional variants show some differences, and the USB hub details are not consistently reported. Confirm the exact unit, included cables and stand before publishing final inventory specifications.

Before You Buy
- Confirm the part number UM.CB2AA.001 and full model suffix, as CB342CK regional variants may differ in brightness, contrast, USB connectivity and HDR features.
- Ensure your computer supports 3440 × 1440 output through a compatible HDMI or DisplayPort connection.
- The native refresh rate is 75Hz, so this model is focused more on productivity and ultrawide viewing than competitive high-refresh-rate gaming.
- Acer's US listing describes HDR readiness, but the listed 250-nit brightness is modest compared with monitors designed for brighter HDR performance.
- Check the USB hub's port count and whether the upstream USB cable is included if you plan to connect peripherals through the monitor.
- Confirm warranty coverage, included accessories, stand adjustments and local availability with the seller.
