    product overview

    With the LMP Attach Dock Pro 4K, we packed a multitude of features in a highly functional, yet only minimally interfering, USB-C dock that makes working with the great iMac even more comfortable. Besides bringing the most used ports from the back side to the front, it also feature the most widely used video ports so working with a 2nd monitor is but a few clicks away. And it’s not just any ordinary resolution and refresh rate these ports offer, but a whopping UHD 4K @ 60 Hz. This makes it stand out from the USB-C dock crowd, allowing for brilliant pictures on an attached display or TV.

    On the front side, you win no less than three USB 3.0 and a USB-C port (for data), an SD and microSD card reader and a 3.5mm audio jack (while connecting to a Thunderbolt 3/USB-C port and two USB 3.0 ports of the iMac in the rear side). So it’s a total of 7 ports in front and 3 video ports in the back that let’s you connect to your peripheral devices and a 2nd display at the same time – along with more free ports on the iMac’s back side. In fact, the USB 3.0 ports gather enough power to even charge an iPad, run up to three 2.5″ HDD/SSD, exchange data with your SD or microSD card and enjoy a 2nd display in the highest 4K resolution with 60 fps refresh rate.

    Thanks to its patented mounting spring mechanism, the LMP Attach Dock Pro is mounted to the iMac’s vent holes in just a few seconds and ready to go in less than a minute. Highly functional, yet only interfering minimally with the iMac’s appearance – the all-new Attach Dock Pro makes working with the new iMac even easier!

    Works with 21.5″ iMac and 27″ iMac/iMac Pro with Thunderbolt 3 (USB-C) ports. It requires one free Thunderbolt 3 (USB-C) and two free USB 3.0 ports.
