I have my TV hooked up to a receiver with an HDMI cable. I have the cable, a DVD player, a hard drive, and the Wii hooked to the 4 HDMI slots on the receiver. I can only get the TV to play the cable. I have taken my computer monitor and hooked it to the HDMI cable and it shows me all four devices. Is there a setting on the TV that needs to be changed to recognize there other devises?
