clock2x, no-clock2x

Enable 27MHz pixel clock (default: auto). Enabling doubles the refresh rate for interlace scan modes. Disabling halves the refresh rate for progressive scan modes.

This depend on a compatible video encoder or transmitter not mangling its input.

size2x, no-size2x

Enable 2× video oversampling (default: auto). Enabling halves the refresh rate.
If the video format's horizontal resolution is less or equal to 682, the internal resolution is doubled instead.

This depend on a compatible video encoder or transmitter not mangling its input.

Template:Anchor--ipv4-address=<aaa.bbb.ccc.ddd>

Set static IPv4 address.

Template:Anchor--ipv4-gateway=<aaa.bbb.ccc.ddd>

Set static IPv4 gateway.

Template:Anchor--ipv4-netmask=<aaa.bbb.ccc.ddd>

Set static IPv4 netmask.

Template:Anchor--network, --no-network

Enable Broadband Adapter features (default: yes).
