Has anyone tried airplay mirroring on the lion mountain beta? As per other posts I'm fixated on trying to find a solution to allow me to use my 2 24" monitors with my 2012 mba. I don't have money to buy TB displays. Wondering how much lag there is from air to apple tv3. Could I use mini display to 1 screen and airplay mirroring to the other? Also will is provide 1080p on mirroring even tho my mba is on a lower res. All help appreciated.
