This high-performance Thunderbolt 3 adapter lets you add two 4K 30Hz HDMI displays to a computer, through a single Thunderbolt 3 port (USB-C). Functioning as an external 2-port graphics adapter with audio support, this is a compact and convenient alternative to a laptop dock for times when you don't need full docking capability. Plus, the display adapter keeps other Thunderbolt 3 ports free, so you can connect additional peripherals. The adapter delivers smooth, high-resolution graphics, making it easier for you to multitask while working on demanding applications. You can extend your laptop screen onto two additional 4K monitors and stream independent content to each at resolutions of up to 4096 x 2160p - perfect for editing 4K video or other high-resolution applications such as creating CAD drawings or reviewing medical imagery. With two displays, you can work more efficiently from your laptop, so you can accomplish more in the same amount of time. Plus, with each display delivering 4K performance, you can have four times the screen space compared to 1080p. Creative professionals can be more productive with the freedom to edit 4K video on one display while previewing raw video playback on the second 4K display. This adapter helps to keep your system running at peak performance. Unlike USB external video solutions, Thunderbolt 3 lets you run Ultra HD 4K resolution at 30Hz on both displays without draining system resources. Because it's backward compatible with your high-definition 1080p displays, this is a great accessory for home, office or other desktop workspace applications.
