Additionally, there is a DisplayPort interface that supports 720p, 1080p, 4K, and 5K displays.
On its front, the 2big has a built-in USB 3.2 Gen 2 Type-A port, which can charge your USB device or connect a USB drive or digital camera for offloading files, as well as a CompactFlash Type I and UHS-II SDXC card slots, allowing you to directly download content from your drone, DSLR, GoPro, and more. This dock can store hundreds of hours of 4K footage and hundreds of thousands of raw images.
