Wireless Screen Sharing Device — App-Free Casting From Any Laptop or Phone
A plug-and-press wireless presentation device for meeting rooms and classrooms. One 3-in-1 button casts from Windows, Mac, iOS and Android — to a Tralltech display or any HDMI screen, with no app to install.
Built-in sharing vs. the T-VID-WLS
Tralltech interactive flat panels already include built-in wireless sharing — so the T-VID-WLS is an add-on for specific cases, not a required part of every room. Here is when an integrator should specify it.
| Requirement | T-IFP built-in sharing | Add T-VID-WLS |
|---|---|---|
| Cast a laptop or phone to a Tralltech IFP | Covered | Optional |
| Cast to a non-Tralltech display, projector or LED wall | No | Yes |
| One-press physical button instead of an app | App-based | Yes |
| Two sources on screen at once (split view) | No | Yes |
| Touch-back control of the laptop from the screen | Limited | Yes |
One button. Any device. Any screen.
The T-VID-WLS is a business-grade wireless screen sharing device built around a 3-in-1 transmitter button — HDMI, Type-C and USB in one unit. A presenter plugs it into their laptop, presses once, and the screen appears, with no app or driver for most devices.
Because the receiver outputs HDMI, it casts to a Tralltech interactive flat panel or to any other HDMI display or projector — making it the add-on integrators reach for when a room has mixed devices or non-Tralltech screens.
Every unit is CE / FCC / RoHS certified and available for OEM customisation from 10 units.

What is a wireless screen sharing device and how does it work?
A wireless screen sharing device lets a laptop or phone show its screen on a meeting-room display without cables. With the Tralltech T-VID-WLS you plug the transmitter button into your laptop, press it once, and your screen appears on the display — no app or driver needed for most devices.
Do I need a wireless screen share device if my interactive display already has built-in casting?
Not always. Tralltech interactive flat panels already include built-in wireless sharing, so for casting to the IFP itself you may not need anything extra. The T-VID-WLS is for cases where you want a one-press hardware button, a two-source split screen, touch-back control, or casting to a non-Tralltech display or projector.
Does wireless screen sharing require an app or software?
No. The T-VID-WLS works app-free and driver-free for most devices — the transmitter button casts from Windows, Mac and Type-C laptops by plugging in and pressing once. It also supports Miracast, AirPlay, WiDi and Chromecast directly, so phones and tablets can cast without installing anything.
Which devices and operating systems can cast to it?
The T-VID-WLS supports Windows 7/10/11, macOS, Linux, Android and iOS. The standard transmitter is a 3-in-1 button with HDMI, Type-C and USB connections, so it works with almost any laptop, phone or tablet.
Can it cast to a non-Tralltech display or projector?
Yes. The T-VID-WLS receiver outputs HDMI, so it can drive any HDMI display, projector or LED wall — not only Tralltech interactive flat panels. This makes it useful when a system integrator needs wireless presentation on mixed or existing screens.
Can two people share their screens at the same time?
Yes. The T-VID-WLS supports a two-screen split view, so two sources can be shown side by side. It also supports touch-back control, letting a presenter control their laptop from the display.
