Klick&Show

4K transmitter

Expand your setup.

Complete your Klick&Show system with the matching Klick&Show 4K WiFi transmitters to include more participants in the meeting and increase device compatibility.

2 types of Klick&Show 4K transmitters are available: either for HDMI or USB-C connection.

Klick&Show HDMI and USB-C transmitters are true plug-and-play devices and enable completely software- and driver-free content mirroring. Using them is as easy as connecting an external PC monitor: Connect the transmitter to the video port of your computer or compatible HDMI or USB-C device and click the Show button to share live content wirelessly to the main display. All transmitter types allow you to mirror either the primary or extended desktop.

High-resolution 4K transmission with low latency

Outstanding performance is guaranteed thanks to hardware-accelerated transmission technology. An integrated chip ensures streaming with particularly low latency, so that your content is mirrored wirelessly on the main display in brilliant quality with up to 4K resolution without using up your laptop's computing power.

Two-color LED status indicator

The attractive design features a multi-color LED status display and, in addition to the show button, two function buttons for triggering additional functions.

Plug & Play

The built-in WiFi module allows the transmitters to connect automatically to the Klick&Showbase unit.
A simple "click" on the transmitter's show button starts or stops streaming.

Flexible control and individually configurable functions for maximum meeting control

While clicking the transmitter's show button starts and stops streaming, the function buttons allow you to pause transmission temporarily or switch from split-screen mode to full-screen display, for example.

When used with the top-of-the-line K-FX Plus model, additional function assignments can even be customized, such as for switching the dual-cam function, dual-UCC function, or the HDMI input. The K-FX Plus also allows you to mirror the main display to share local content with remote participants in a BYOM call.

Mirroring the primary or extended desktop

When connected to Windows or MacOS computers, all transmitters enable the "touchback" function, allowing the computer to be remotely controlled via an interactive display on the base.

Transmitter Storage

The optionally available TRAY-4K in a matching design keeps the conference table tidy.

Use without transmitter, directly via app.

Laptop users without a transmitter simply start the Klick&Show app for Windows or macOS to mirror content to the main screen.

Content from mobile phones and tablets can also be easily shared via AirPlay, Miracast, Google Cast, or the free Android app.
