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.
It is normal that any USB-C hub or dock becomes hot when attached to the laptop. The aluminum housing is meant to dissipate the heat from the inside to the environment. There is a number of chipsets working on the inside which are producing some heat since they are constantly in a stand-by position to react quickly should any port be used. The surface temperature is well within the allowed limits and reaches about 40° C in stand-by mode, 43° C under normal use and a max. of 48° C when all ports are in full use, CPU load at 100% and PD attached. The heat does neither pose a danger to the laptop or any attached device, nor does it influence the USB-C hub’s/dock’s performance or even shorten the life-span.
Furthermore, the surface appears to be hotter than it actually is since it is touched with the very senstive fingertips. We suggest to remove the USB-C hub/dock when not needed in order not to emitt unnecessary heat to the environment and not to use any energy.
Basically, you can use only the iMac (27-inch, Late 2009) and iMac (27-inch, Mid 2010) with a Mini-DisplayPort connection with the current Mac with Thunderbolt 3 (USB-C) ports. You need a USB-C to Mini-DisplayPort adapter (e.g. 16134/16138, LMP USB-C to Mini-DisplayPort adapter) or a USB-C dock with Mini-DisplayPort port (e.g. 18641/18645/19009, LMP USB-C Travel Dock 4K 9 Port or 17113/17278/18954, LMP USB-C Compact Dock 4K 8 Port or 17116, LMP USB-C Display Dock 4K 10 Port). Then a Mini-DisplayPort to Mini-DisplayPort cable (8305, LMP Mini-DisplayPort to Mini-DisplayPort cable) must be attached to the dock and the iMac.
With iMac (Mid 2011 to Mid 2014), it is possible to use the iMac as monitor with a Thunderbolt connection only. With a newer iMac, a Target Mode with an iMac is not possible anymore.
