I have a Sony BDVE780W home theatre system and a Dell Inspiron 1525 laptop. The home cinema system works perfectly for everything, including when I connect my PS3 to HDMI input. But when I use the same cable and input to connect to my laptop I dont get any video or audio.
Also when I connect my laptop directly to TV there is no problem, both audio and video work perfectly but I really would like to connect my laptop to home theatre via the HDMI input to use speakers.
I have similar problem but with PC->home theatre connection, no video, nor sound, works perfectly when connected directly to the TV.
Have you found any solution to this problem yet ?
