The U444-06N-VGA USB 3.1 Gen 1 to VGA Dual/Multi-Monitor External Video Graphics Card Adapter lets you connect an additional VGA monitor, television or projector to the USB Type-C (USB-C) port on your computer, tablet, Ultrabook or smartphone. It's an ideal tool for creating digital signage, multitasking, viewing large spreadsheets across screens, editing documents, giving presentations at trade shows and conferences, or playing games and watching movies on large screens. You can extend video from your primary display to another or duplicate the same desktop on both displays. No external power supply is needed. You can use up to six U444-06N-VGA adapters at the same time, connecting up to six additional monitors to a single Windows computer. Just connect the built-in USB-C cable to the USB-C port on your smartphone, tablet, Ultrabook or computer. Then, connect the adapter's VGA port to a monitor using a VGA cable to see and hear full high-definition (HD) audio and video. The U444-06N-VGA supports USB 3.1 Gen 1 data transfer speeds up to 5 Gbps, which is ten times faster than USB 2.0. It also supports HD video resolutions up to 2048 x 1152 (60 Hz), including 1080p.
