When using the connection without the splitter the quality is perfect, it only gets blurry when I use the splitter. I will look into a VGA switch to see if that will help. I have a balun that works up to 300 feet so the distance is fine. I have also looked into a wireless adapter and the quality was not very good on the 3D HDTV, I do however use it on another conference room and it works great but for this room I need another solution. I do think that is does have something to do with the balun as I can do the same setup on another TV with no balun using the same splitter and the quality is fine.
