Hey guys I just purchased a 15" retina macbook pro and I was interested in using my tv as an external monitor. Are there any that would allow me to wirelessly use my tv as a display? An apple tv is the obvious soulution however I don't need one for anything other than a wireless display reciever, are there any cheaper options? I also no just an HDMI cable would work but I would love to remain wireless. Anyway thanks a lot guys.
