This 34-inch curved ultrawide functions as a complete USB-C hub, powering a laptop at 90W while displaying a 3440×1440 panoramic workspace over a single cable. The built-in KVM switch with two USB-C upstream inputs makes toggling between work and personal machines seamless with one keyboard and mouse. Six USB downstream ports at 10Gbps each including a USB-C with 15W charging eliminate the need for a separate dock. An RJ-45 Ethernet pass-through adds wired networking without a dongle.
34″ curved WQHD USB-C hub monitor with 90W PD, KVM, 6 downstream USB 3.2 Gen 2 ports, and Ethernet pass-through.

Notes & Compatibility
The primary USB-C upstream carries DP 1.4 Alt Mode, 90 W Power Delivery and USB 3.2 Gen 2 data. The second USB-C upstream is data-only for the KVM: no video, no charging. The two are not interchangeable, so a laptop in the KVM socket gets neither picture nor power. The USB-C downstream delivers 15 W, phone territory rather than laptop. One USB-A downstream carries BC 1.2 charging at 2 A max. The RJ-45 is a pass-through off the USB-C upstream link, so with no USB-C host connected there is no wired network. Dell’s sheet labels both HDMI inputs HDMI 2.1 (TMDS), but the panel is 3440×1440 at 60 Hz and no 2.1 feature applies, so a Premium High Speed cable covers every input. Built-in KVM switch. HDCP 2.2 throughout. IPS panel, 100% sRGB, 98% DCI-P3.
