I have an Hitachi TV and a Toshiba Blu-Ray Player. When I connect them with an HDMI cable, into either HDMI port (HDMI1 or HDMI2), a pop-up reading "Not Supported" emerges for a millisecond before the Blu-ray screen comes up and vanishes within about five seconds. Then you can here the blu-ray player running, but nothing happens.
What could the problem be? Perhaps they aren't compatible? How can I fix this problem?
