Here’s some wireless screen mirroring on the Nokia Lumia 630 using miracast. As part of the Nokia Lumia Cyan update, Nokia Lumia with WP8.1 Nokia Cyan can now use miracast. Well, select devices, like the 930/ICON/1520 and 630. Oddly, although it’s supposedly physically capable, the Nokia 92x or 1020 aren’t included in the list.
The frame rate looks very good, and sound appears to play through the TV.
