I have been trying to screen mirror my desktop using mezzmo and DirectShow. However, the maximum resolution I could successful mirror was 1600 x 900. When I set my desktop resolution to 1920 x 1080, the video mirrored gets cut as if the TV screen is too short. Also the TV reports another resolution (1XXX x 964 if i'm not wrong). I do confirm that my TV supports 1080p content over DLNA, since I can stream without problems other FullHD videos from my storage to TV using Mezzmo.
