Dell S 34 USB-C Monitor (S3425DW) review

Dell S3425DW is the cheapest way into a full 3440 x 1440 ultrawide from a major brand on this list. Dell lists a 34-inch VA panel at 120Hz with an 1800R curve, a 3,000:1 native contrast ratio and 95% DCI-P3 coverage. Response time is listed at 1 ms GTG in Extreme Mode, and AMD FreeSync Premium handles tearing in games. The practical extras matter for a home office: a USB-C port delivers up to 65W to a laptop, two HDMI 2.1 ports cover a console or a second computer, pop-out ports at the front make plugging in a drive easy, and two 5W speakers save desk space. The stand adjusts for height, slant and tilt. The savings show in the warranty, which is 1 year limited with Advanced Exchange Service, and in the lack of Ethernet or a KVM switch. Brightness is 300 nits with HDR10 support. Dell.com listed it at $419.99 when we checked. We compared documented features and published prices only.
