Hi, it might be a dumb question. But I try to connect my macbook to my panasonic HDTV (not PC competible). I used two cables, the mini-DVI to DVI then DVI to HDMI to the TV, but the TV doesn't have any signal. My TV requires 750(720)/60p or 1125(1080)/60 resolution, I changed my macbook to 1152*720. Does anyone has any idea what it might be because of? I really appreciate your help!
