In order to mirror in 1080p, you must have iOS 6 or newer on your iOS device. You would also need a display that supports 1080p or higher. If you meet these two prerequisites, proceed by opening AirServer preferences and clicking the Mirroring tab. Set the device optimization to "1080p - Recommended". Once all of these pre-requisites are met, AirServer will automatically negotiate 1080p streaming and boost your image quality!
