@SeeFights Vivi is a Linux/Android box ( running ViviOS ) that has HDMI out, audio out, POE ethernet, WiFI and USB pass through ports. It connects to your network via ethernet or WiFi and teachers use a app or web page to connect to the device wirelessly. You can share screen, share your camera, share a tab and play YouTube videos ( without the ads ) and with play content you don't even have to share your screen, the YouTube video plays directly from the box thus preventing lag and sync issues when compared to playing it whilst sharing a teachers screen. It supports all platforms so Android, Linux, Chrome, iOS, MacOS and it has a web app. They also have a software version for FireOS, AppleTV and Android if you don't want the physical boxes. Students can also share to the device but the teacher is always in control of that side of the casting.

@SeeFights Vivi’s screen sharing is designed to be very low bandwidth as it uses it's own proprietary protocol which is optimised for efficient performance across school networks either wifi or ethernet. You can also change the streaming method to WebRTC that will automatically throttle or speed up the stream depending on network load. I have no idea how they do it but it does provide a stable and low bandwidth screen sharing / mirroring solution.

@SeeFights have you looked at Vivi? You can use Vivi for wireless screen sharing, which has helped us avoid the long HDMI cable runs altogether. It works over Wi-Fi or LAN and supports 4K screens, so staff can present directly from their laptops without needing to plug in. It’s been a good cable-free solution, especially in rooms where long HDMI runs were a hassle or unreliable.

@Alis_Klar The Chrome app is indeed EOL, but Vivi has updated their platform to work directly through the web browser instead. Interestingly, older Chromebooks handle it fairly well, since it uses WebRTC. This protocol adjusts dynamically based on your network quality, so performance tends to scale with the available bandwidth and connection stability.

@Alis_Klar Have you looked at Vivi? Vivi supports wireless screen mirroring across all major platforms. You can use any device at the front of the class including, interactive panels, projectors or TV's and achieve the same result with wireless touchback on both devices. That way, you're not reliant on aging IR boards for input and Vivi gives you the flexibility for your teachers to teach wirelessly and interactively, without the hardware headaches.

Lots of rumours going around that they are EOL, might be better off investing in something more long-term, especially if you've got a mix of devices. I've worked with a few schools that have been recommended Vivi as an alternative.
