The LMP USB-C Video Hub combines video output (HDMI up to 4K @ 30 Hz) with fast data transfer (3x USB 3.0) as well as pass-through power (Power Delivery over USB-C port) to the 12“ MacBook and 13“ and 15“ MacBook Pro. Its USB-C port is capable of transferring data from and to your Mac laptop as well. Last but not least there is a designated USB 3.0 port which charges a smartphone or tablet with up to 7.5W (5V/1.5A).
The aluminum housing is sturdy and stylish alike and it takes care of the evolving heat. With its 15 cm connecting USB-C cable, the Network Hub keeps the cable clutter away from your laptop. Connect your Mac laptop or iMac to the any display or TV with a most widespread HDMI port and exchange data to your proximity.
Note: Not compatible with Apple USB SuperDrive. May evolve heat when in use. For highest possible resolution of 4K @ 30 Hz over HDMI, attached display or TV must support the resolution and refresh rate.
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.
