Dell UltraSharp U3423WE (34.1-Inch Curved Ultrawide QHD IPS Black/60Hz/5ms/98% DCI-P3/HDR400/90W USB-C Ethernet Hub) Review
The UltraSharp U3423WE is Dell's productivity-focused curved ultrawide, using the brand's higher-contrast IPS Black panel technology alongside a 90W USB-C power delivery hub with Ethernet for single-cable professional docking.
The IPS Black panel delivers approximately 98% DCI-P3 color coverage with roughly double the contrast of standard IPS panels, matching the technology found in Dell's UltraSharp U2723QE also in this catalog. At 60Hz with a 5ms response time, the U3423WE is built for productivity and content work across its wide 21:9 canvas rather than gaming. Against the LG 34WP65C-B also in this catalog, the U3423WE trades LG's gaming-oriented overclockable refresh rate for Dell's higher-contrast IPS Black panel and extensive professional docking connectivity including Ethernet.
