i-tec USB 3.0 HDMI 2x 4K Ultra HD Display Adapter, 2x HDMI 4096x2160@60Hz, external monitor graphics card with latest DisplayLink chip 6950, for MacOS, Windows, Android, laptop, PC, tablet


Extend your desktop with two external HDMI monitors. The adapter supports 2x 4K resolution 4096x2160@60Hz including audio signal. 

You can use the adapter for example with MacBook Pro 2016, DELL XPS12, DELL XPS 13, DELL XPS 15, HP Elite X2, HP EliteBook Folio G1, Spectre x360, Lenovo Thinkpad P50, Lenovo Thinkpad P70, Chromebook Pixel 2015, Acer Switch Alpha 12 and other devices.

The adapter is suitable for designers, graphics and other users who work with multiple screens at the same time. Its performance lets you run even the most demanding applications on one or two independent displays, making it ideal for editing 4K 60Hz videos or for other Ultra HD tasks such as creating CAD drawings or viewing medical shots.

With the "Expand" and "Mirror" modes, you can work with apps across two monitors (e.g. wide spreadsheets), work on one monitor and search for information on the Internet using the second one, compare several documents at once, without constantly skipping open windows, view panoramic images over two monitors, track charts and current data at the same time, show several presentations at once without the necessity to have another computer, etc.

Use is very easy. Just connect the adapter to your computer either via the standard USB 3.0 interface or, thanks to the included reduction, via the modern USB-C or Thunderbolt™ 3 port. More about the Thunderbolt™ 3 / USB-C connector here. Use the HDMI cable to connect the imaging device, then you can start using it immediately.

Drivers are installed automatically from the system.

Question: Can I use Adaptor to transfer signal from HDMI/Display Port port to VGA/DVI Port?
Answer: We do not recomend transfering Digital signal (HDMI/DVI) to Analog (VGA/DVI) due the technological restrictions of Analog ports (their low data bandwidth), these adaptors might not work corectly.


Question: Display Port doesn’t work after connection to my MacBook even after installation of Display Link drivers.
Answer: After update of 10.13 (High Sierra), Apple added a safety element that blocks automatic installation of Display Link drivers; to enable correction function, it is necessary to allow an exception for Display Link Corp in the Settings of protection of your MacBook.
