Yealink RoomCast vs. BenQ InstaShow WDC15: Which wireless presentation system is the best?

The $499 Yealink RoomCast and the $799 BenQ InstaShow use different design thinking to enable presenters to mirror their screen. The Yealink RoomCast is a receiver that connects to your network to enable the presenter to share their screen using either their app, Miracast, Airplay, or Google cast in a meeting. The BenQ InstaShow uses a receiver and advanced transmitter button that enables the presenter to share their screen without loading any app or having to log on to a network. This means that while the Yealink RoomCast will be less expensive, the InstaShow is simpler to use and can adapt to a wider variety of devices with less risk of meeting room drama or awkward pauses when something doesn’t work. Yealink also sells a wireless pod that can be plugged into the device and stream to the RoomCast receiver similar to the InstaShow button., At the time of this article, the price for this button was about $399. 

The BenQ InstaShow WDC15 button does the heavy lifting of screen mirroring almost any device that has an HDMI or USB-C port. This means that you can use it with any MacBook, Windows notebook, Chromebooks, iPads, mobile phones, and even Raspberry Pi using the USB-C port. Because you can change the cable on the button to HDMI, the InstaShow will also work with Blu-Ray players, Xbox and other gaming consoles, and video sources like cable TV boxes and video switchers to ensure that your presenter can share. Because the Yealink RoomCast uses third party protocols like AirPlay and Miracast, it can support most common notebooks and phones, but not other devices like media players and non-computer video sources. Also keep in mind that your guests may also have to log into the correct network for AirPlay and may update their drivers or restart their computers using Miracast, which can create awkward delays in the meeting.

In business, video is primarily used as a powerful marketing tool to engage customers, increase brand awareness, highlight products and services, tell a story, and build trust. The InstaShow is the only leading wireless presentation system that can wirelessly stream copy protected movies and content from phones, notebooks or media players. For example, if you want to share a clip from a movie downloaded via iTunes on your iPhone 16,, just plug in a button to the USB-C port and in a few seconds, the InstaShow will mirror the screen just like you were connected to your monitor.  The Yealink RoomCast does not support HDCP content either through their app or via the third-party protocols, so if you need to play downloaded movies or stream content from Netflix, ESPN, or other sources, you’ll have to use a cable.

Want to keep prying eyes from seeing your latest product roadmap or pro-forma financial statement? While both the Yealink Roomcast and BenQ InstaShow use encryption, the InstaShow is the only wireless presentation that has been certified from known common hacks used to enable unauthorized access to presentation content and even network access. The BenQ InstaShow has been tested and certified under the rigorous CVSS 4.0 security specification. This offers more peace of mind for IT managers who are worried about hackers using the network connection used by Yealink to gain unauthorized access to the network or watching a presentation from outside the room. The InstaShow can also be used without any direct network connection, creating an air bridge to keep your network safe – without compromising performance.

As of July 2025, the Yealink RoomCast does not have any CVSS certification or known third party testing. 

Both the BenQ InstaShow and Barco Yealink Roomcast are commercial grade BYOD screen mirroring systems, and are more expensive than consumer grade wireless HDMI adapters found on Amazon and other online sources.    The list below highlights some of the feature differences as well as what companies need to budget when they are considering installing one of these models.
