Wireless presentation system EZCast Pro Dongle II

EZCast Pro Dongle II is a compact wireless presentation system designed to mirror screens and stream media to TVs and projectors at resolutions up to 4096 x 2160. The device uses an updated GHz-level SoC and 1 GB DDR3 memory to provide improved processing power, and supports 802.11ac (Wi‑Fi 5) on the 5 GHz band with a 2T2R MIMO antenna configuration for higher throughput and stable connections. It works with Windows, Android and iOS devices and supports both AirPlay and Miracast protocols for cross-platform screen mirroring.

Advantages

The dongle delivers faster wireless transmission and greater stability thanks to 5 GHz 802.11ac support and a 2T2R antenna design. Increased memory and a higher-performance SoC enable smoother handling of resource-intensive tasks such as 4K video streaming. Built-in apps for presenters include EZCast Pro for single-to-multiple screen broadcasting and EZCast Pro features for realtime note-taking, document and photo streaming, and host control of meeting sessions.

How to use

Plug the EZCast Pro Dongle II into an available HDMI port on the TV or projector and provide power according to the device instructions. Connect your source device (laptop, tablet, or smartphone) to the same 5 GHz Wi‑Fi network created or provided by the dongle, then start the appropriate mirroring protocol or the EZCast Pro / ProCast app on your device. For multi-screen broadcasting, install and launch the ProCast app on the presenter laptop and follow the in-app prompts to mirror to multiple displays simultaneously.

Recommendations

For best streaming performance, use the 5 GHz Wi‑Fi band, keep the dongle in direct line of sight of the presenter device where possible, and ensure the host network has sufficient bandwidth to handle 4K content. Use the ProCast app for classroom or conference setups that require 1-to-many screen broadcasting, and enable host controls to manage meeting sessions.
