DELOCK USB Type-C to Dual HDMI Adapter – 4K 60Hz + USB Port
Delock Item No. 87780
Turn a single USB-C connection into a dual-monitor workstation. This compact Delock adapter lets you connect two HDMI displays to a compatible laptop, PC or mobile device, while also providing a USB-A port for a mouse, keyboard, USB drive or other accessory.
Two Screens from One USB-C Port
For anyone working from a laptop, this is a particularly useful little accessory. Connect it to a compatible USB-C port and you can add two HDMI monitors, TVs or projectors.
It supports MST (Multi-Stream Transport), allowing compatible Windows systems to extend the desktop across multiple displays rather than simply showing the same image.
4K Ultra HD Support
There's an important distinction worth explaining clearly to customers:
One HDMI display connected: up to 4K 3840 × 2160 @ 60Hz
Two HDMI displays connected simultaneously: up to 4K @ 30Hz per display.
So the product title's 4K 60Hz specification is correct, but customers shouldn't assume they'll get 4K 60Hz on both monitors simultaneously.
There's a USB Port Too
Delock has also included a USB Type-A port, so you can connect something like a keyboard, mouse or USB memory stick.
That makes this more useful than a basic USB-C-to-HDMI adapter – it effectively becomes a very compact mini docking solution.

Important Compatibility Note
The computer's USB-C port needs to support DisplayPort Alternate Mode (DP Alt Mode), or you can use a compatible Thunderbolt 3 port. A USB-C connector by itself does not guarantee video output.
There are also limitations with some Apple Silicon MacBooks. For example, Delock notes that standard M1, M2 and M3 MacBooks support only one additional external monitor with this adapter, whereas certain Pro/Max configurations can support more.
Why We Think It's Cool
This is exactly the sort of computer accessory we like for ITsCool – small, practical and capable of completely changing a laptop setup. Keep it in your laptop bag and you've effectively got a portable dual-monitor connection wherever you work.
ITsCool Verdict
A great accessory for home offices, business users, students and anyone who regularly works with multiple screens. Particularly handy if your modern laptop has plenty of power but very few physical display connections.
