After much aggravation trying to get mirroring to work, I finally figured out it was the tv. First I flashed the updated aggressive freedom kernal v0.9, hooked it up to the L.R. tv, nada. Then I tried downloading HDMwIn and running that with the updated kernel, nada. Tried B.R. tv with and without HDMwIn, different cables, wiping cache anything I thought would help, nada. Fast forward a couple weeks, I decide to get a tv for the kitchen. Set it up plug the EVO in and boom mirroring. No HDMwIn, no wiping just hook it up and go.
edit: Also make sure HDMI cable is securely plugged in
So for anyone interested:
Vizio mod# E220MV(from Sam's)
