The curved Dell S3423DWC USB-C monitor is designed for wide-format work and multimedia. Its 34-inch (86.42 cm) VA display has a 21:9 aspect ratio, native resolution of 3440 × 1440 and a 100 Hz refresh rate, giving you room for multiple windows and detailed content.
The panel has 109 ppi pixel density, 99% sRGB coverage, typical contrast of 3000:1 and a 4 ms response time in Extreme mode. Anti-glare 3H coating helps reduce reflections, while AMD FreeSync supports compatible variable-refresh applications.
Connect devices through two HDMI 2.0 ports or USB-C, which supports DisplayPort 1.4 Alternate Mode and USB Power Delivery up to 65 W. The USB hub has one Type-B upstream port and two Type-A downstream ports. A built-in KVM switch lets you control up to two computers.
Integrated speakers provide 5 W each. The stand offers 100 mm height adjustment and tilt from -5° to 21°, and the monitor supports a 100 × 100 mm VESA mount.
Package contents: USB-C and USB upstream cables.
