▪

The secondary network can impact the Miracast screen mirroring quality. For best results, disable

the secondary network when using Miracast.

▪

If the Wi-Fi network is enabled, the same 802.11 channel is also used for the Miracast connections.

▪

When you disable Miracast, both the Require PIN Every Connection and Operating Channel

options are reset to their default values.

Miracast Operating Channel

Pano system uses the operating channel to transmit Miracast mirroring content.

Notes on Default Operating Channel

Pano selects the DEFAULT channel automatically so the system can support both Miracast and the

secondary network at the same time.

When you enable the secondary network, the Miracast Operating Channel option is disabled to ensure

Miracast and the secondary network use the same channel. However, if the secondary network is

connected to a Wi-Fi Access Point (AP) working on a Dynamic Frequency Selection (DFS) channel,

Miracast may not work properly. This is because some Wi-Fi drivers don't support DFS channels well.

Notes on Selecting a Non-default Operating Channel

If you don't use a secondary network, you can select a non-default Miracast operating channel to provide

the best performance in your environment.

Note the following when you choose a non-default channel:

▪

Select a channel with less channel saturation in your Wi-Fi environment. Channel saturation

impacts the quality of the mirrored content.

▪

Select the same channel as the Wi-Fi Access Point (AP). This reduces channel switching from the

Miracast clients. Channel switching leads to latency in your mirrored content.

Note: When you disable Miracast, the Operating Channel option is reset to its default value.

Select the Miracast Operating Channel

You can specify the Miracast operating channel for better content quality.

Make sure you're not in a content mirroring session. You can't change the Miracast operating channel

during an ongoing content mirroring session.

Procedure

1. In the system web interface, go to Security > Wireless and Screen Mirroring.

2. Select the Enable Miracast option to enable screen mirroring for Miracast-certified devices.

3. Select an Operating Channel.
