When it comes to video ports, the LMP Display Dock has them all, making it the most comprehensive USB-C video dock in the market: HDMI (4K @ 60 Hz), Mini-DisplayPort (4K @ 30 Hz), DisplayPort (4K @ 30 Hz), DVI (1080p @ 60 Hz) and VGA (1080p @ 60 Hz). Wherever you go, whatever video port you may need – the Display Dock covers them all in a single USB-C dock.
Thanks to its dual USB-C connection design, the Display Dock lets you extend your video content to two external displays (dual 4K monitor support), each at its maximum resolution and refresh rate. So you can have as many as three different pictures running independently at the same time (extend mode) and all with up to 4K resolutions.
It is the only USB-C dock that supports 4K @ 60 Hz video output via HDMI and it comes at less than half the price of a Thunderbolt dock. Ideal for the professional user, the passionate movie watcher or the avid gamer alike – take advantage of 4K video with high-frequency 60 Hz refresh rate.
Besides the 5 video ports, the LMP USB-C Display Dock connects to the outside world via Gigabit Ethernet and its two USB 3.0 ports of which one can charge a smartphone or tablet with up to 1.5A. The USB-C port allows pass-through power (Power Delivery) with up to 55W or can be used alternatively for data transfer (5 Gbps). The audio out port (3.5 mm jack) allows to connect a speaker or headphone. For full functionality, both USB-C host connecting cables must be plugged in to the host. Compatible with all Macs with two free Thunderbolt 3/USB-C ports.
Note: Dual monitor support can be achieved in these combinations only: HDMI (4K @ 60 Hz) + Mini-DP or DP (4K @ 30 Hz); HDMI (4K @ 60 Hz) + VGA (1080p @ 60 Hz); Mini-DP or DP (4K @ 30 Hz) + DVI (1080p @ 30 Hz); VGA (1080p @ 30 Hz) + DVI (1080p @ 60 Hz). It is NOT possible to use the combination HDMI + DVI!
No. The Display Dock has two USB-C connecting cables to the host. Only by plugging in both connecting cables to the host, the full functionality of the all ports can be used. As the 12″ MacBook has only a single USB-C port, it makes the full use of the Display Dock impossible.
No. There are a few limitations as to which combinations of ports can be used at the same time. Basically, it is the HDMI port plus another port from Mini-DisplayPort, DisplayPort or VGA or the DVI port plus these ports. HDMI + DVI at the same time will not work as well as the combinations among Mini-DisplayPort, DisplayPort and VGA.
While advertised as being capable of displaying at UHD (4K) with a maximum refresh rate of 60 Hz, some monitors can do this only via their (Mini-)DisplayPort while their HDMI port can do 4K@30 Hz only. Check the specs of the monitor carefully to find out if your monitor really can do the 60 Hz via HDMI.
The Display Dock assembles a good number of chipsets on its PCBA as it features 10 ports in total. Once the Display Dock is plugged in to the host, all chipset are ready to react whenever a port is being used. This means that energy must supplied to the PCBA and the chipset will emit a certain amount of heat (as all chipset do). The heat is dissipated through the aluminum surface as metal is the ideal heat dissipator. The surface therefore becomes hot even when only little action is taking place. However, the maximum temperature of the surface (with all ports in use, PD attached and the host with full CPU load – which would never occur under normal circumstances) will to up to 48° C. It might feel hotter than it is since one typcically touches the surface of the Display Dock with the very sensitive fingertips. This temperature is well within the allowed and safe range and it will not affect the use or shorten the lifespan. Nevertheless, when you are not using the Display Dock, you may unplug it so no unnecessary heat is evolving and not energy drawn from the host.
Basically, you can use only iMac (27-inch, Late 2009) and iMac (27-inch, Mid 2010) with a Mini-DisplayPort connection with 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 newer iMac, a Target Mode with an iMac is not possible anymore.

In order to use the Mini-DP port as an HDMI output and connect 2x HDMI monitors or TVs, you must use an active Mini-DP to HDMI adapter or cable (must be “active”!). An example of an active adapter is P/N 11892, LMP Mini-DisplayPort to HDMI adapter.
