If your TV has a USB port (mine does, and is in no way state of the art) you should be able to power it from that. Not quite a zero cable solution, but it's close.
-Plug it directly into the USB port and use cable+adapter to connect to HDMI.
-Plug it directly into the HDMI port and use cable+adapter to connect to USB.
Actually, a third way would be to use cables on both ends, but that just seems kind of silly.
