According to the 4.2 release, "Just connect a wireless display adapter to any HDMI-enabled TV to mirror what’s on your screen quickly and easily." But I can not find which wireless display adapters are supported. Does anyone know?
Okay, more information. It appears that the wireless display adapter has to support Miracast. I've yet to find any adapters on https://certifications.wi-fi.org/search_products.php?advanced=1&en
that are certified and shipping
. I also can not find where the Nexus 7 has been certified, so .....
I did find one device, PTV3000, on Newegg that is suppose to support Miracast, but the reviews for the product were not encouraging. Also, on its web site it says "*PTV3000 supports pre-standard compliant Miracast™ wireless enabled display devices." What that means I have no idea. If anyone has this product and has tried it with the Nexus 7 it would be great to know if it works okay.
