DIGITUS Wireless HDMI Extender Set — Full HD 1080p/60, up to 50 m, Plug & Play
Wireless Full HDUp to 50 m (line of sight)Point-to-point 1:1Dongle-size units
The DIGITUS DS-55318 is a wireless HDMI extender set — one transmitter and one receiver dongle — that sends Full HD video (up to 1080p/60) and stereo audio from a source to a screen up to 50 m away in clear line of sight. It suits meeting rooms, waiting areas, home cinema projectors and short-term installs where you want the source on the desk and the picture on a distant screen without running a cable.
Both units plug straight into HDMI ports and can draw power from the HDMI port itself (at least 0.5 A), or from the supplied Micro-USB cables connected to any USB port. They pair automatically on the best available Wi-Fi channel; there is no driver, app or network setup.
Before you order: 50 m is the manufacturer figure with unobstructed line of sight. Walls, glass and people reduce range or interrupt the picture. Many TV and laptop HDMI ports cannot supply 0.5 A — use the Micro-USB power cables if the units do not light up.
What's in the Box
- 1× transmitter dongle (HDMI)
- 1× receiver dongle (HDMI)
- 2× Micro-USB power cables (0.8 m)
- 2× short HDMI extension cables (0.15 m)
- 1× quick installation guide
What It Means in Practice
- Point-to-point only: one source to one screen. For several presenters sharing one screen, the Click & Present Mini (DS-55319) is the right DIGITUS set.
- Latency is about 120 ms — fine for presentations, TV and video, noticeable in fast games.
- The short HDMI extension cables help where the HDMI port is recessed or crowded.
- The link is encrypted with WPA2, so neighbours cannot receive the picture.
What Will Not Work
- No 4K: maximum resolution is Full HD 1920x1080 at 60Hz.
- No keyboard, mouse or IR remote back-channel.
- Not for one-to-many distribution — it pairs one transmitter with one receiver.
- Distance through walls is not guaranteed.
- Not for outdoor or damp areas (0–40°C, indoor use).

Frequently Asked Questions
Do I need a power socket at each end?
Not necessarily. Each dongle can be powered from the HDMI port (0.5 A or more) or from any USB port, such as the TV’s USB port, using the supplied cable.
Can I add a second screen?
No. This is a 1:1 set. For one-to-many wireless distribution look at DIGITUS DS-55346 (1:4, Full HD) or DS-55328 (1:4, 4K/30Hz).
Will it work with a games console?
Yes as an HDMI source, but the approx. 120 ms delay makes fast-paced gaming feel sluggish.
Singular Expert Insight · Buyer's Guide
For a single source and a single screen in the same room or an open space, a dongle set like the DS-55318 is the quickest fix — no wall chasing, no installer. When the screen is in another room or the picture must never drop, run a CAT cable instead and pair it with a wired extender; our
network cables cover the lengths you need.
✓ Buy it if you need a quick, cable-free Full HD link from one device to one screen across a room.
✕ Skip it if you need 4K, several screens, remote keyboard/mouse control or guaranteed range through walls.
→ Also consider DIGITUS DS-55323 (4K/30Hz wireless, 30 m) or DS-55319 Click & Present Mini (multi-presenter, Full HD, 50 m).
