I'm using a mini display port adapter to DVI, then convert to HDMI. I also have one that goes direct to HDMI. I have tried putting the DVI signal into a Kramer converter that converts to HDMI. With all of these options I still cannot push the signal through like the Toshiba will. I also tried running a 25' HDMI cable across the floor and through the wall to the router. The signal shows up, then blanks out for a second, shows some static partially on the screen, comes in, goes out, etc. I ran this through a 1x2 distribution amplifier which didn't help.
My quest continues.
