Good info, Looks like the MuxLab Balun connector sends audio and video on cat5 cable. Maybe larger scale video and audio projects use this because running HDMI isnt feasable. Possibly some consumers may not even know it. Ive got a Sony Bravia 46 W series. Not sure what effect not having "deep color" will mean.
