Miracast over LAN poor video quality issue with MediaTek RZ616 Wi-Fi 6E Wireless NIC

This article is relevant for ScreenBeam 1xxx-Series and 960 products.

We have identified a specific video performance issue when connecting a Lenovo device equipped with the MediaTek RZ616 Wi-Fi 6E Wireless NIC to ScreenBeam receivers using the Miracast over LAN method. Affected models include, but may not be limited to, the L13 Yoga Gen 4 AMD-Based systems running driver version 25.40.2.581.

Users may experience significant image delay between their laptop and the ScreenBeam-connected display, audio that lags behind video, or noticeable juddering of video and audio during screen mirroring. Notably, this problem does not occur when connecting via Miracast Peer-to-Peer (P2P) mode.

Lenovo is aware of this issue and is actively collaborating with MediaTek to deliver an official fix. For further assistance or updates, please reach out to your Lenovo representative.
