DIGITUS 4K Wireless Video Extender Set — USB-C to HDMI, 4K/30Hz, up to 30 m
USB-C source to HDMI screenWireless 4K/30HzUp to 30 m (line of sight)No drivers or app
The DIGITUS DS-55324 is a wireless video extender set that takes the picture straight from a USB-C port and shows it on an HDMI display up to 30 m away in clear line of sight, at up to 4K UHD 30Hz (4096x2160) with 2-channel audio. It is made for modern laptops, tablets and phones that have USB-C but no HDMI port — plug the transmitter in, and the meeting-room TV or projector shows your screen.
The transmitter has a USB-C plug for the source and a USB-C socket for power; the receiver has an HDMI plug for the display and a USB-C socket for power. They pair automatically on the best 2.4/5 GHz channel, with no driver, software or app.
Before you order: The source’s USB-C port must output video (DisplayPort Alternate Mode or Thunderbolt). Many budget phones and some laptops’ data-only USB-C ports do not — check for the DisplayPort or Thunderbolt symbol, or send us the model. 30 m needs clear line of sight.
What's in the Box
- 1× transmitter dongle (USB-C)
- 1× receiver dongle (HDMI)
- 2× USB-A to USB-C power cables (1 m)

What It Means in Practice
- Ideal for MacBooks, USB-C Windows laptops, iPad Pro/Air with USB-C and Android phones with DP Alt Mode.
- Latency is about 100 ms — good for presentations and video, not for fast games.
- The short USB-C extension cable helps when the laptop’s port is tight next to another plug.
- The link is encrypted (AES-128, WPA2).
What Will Not Work
- Will not work from USB-C ports without video output (no DP Alt Mode / Thunderbolt), nor from USB-A ports.
- No HDMI input on the transmitter — for HDMI sources choose the DS-55323.
- No 4K/60Hz.
- No keyboard/mouse back-control and no multi-screen distribution.
- No guaranteed range through walls.

Frequently Asked Questions
Will it work with my iPhone?
iPhones with USB-C that support video output over USB-C can work; Lightning iPhones cannot. Send us the model and we will check.
Does the laptop charge through the transmitter?
No pass-through charging is published; the USB-C socket on the transmitter powers the transmitter itself.
Can I connect an HDMI laptop?
No — use the DIGITUS DS-55323 with HDMI transmitter instead.
Singular Expert Insight · Buyer's Guide
Most new laptops only have USB-C, which makes this set more practical than HDMI-based wireless kits in modern meeting rooms. For permanently installed sources, or when the screen is in another room, a wired extender over
network cables remains the more reliable option.
✓ Buy it if your laptops, tablets or phones present over USB-C and you want a cable-free 4K/30Hz link to one screen within 30 m.
✕ Skip it if your sources only have HDMI, you need 4K/60Hz, or the screen is behind walls.
→ Also consider DIGITUS DS-55323 (HDMI source version) or DS-55319 Click & Present Mini (multi-presenter, Full HD).
