Hey everyone. I have a macbook pro 13" and have just bought a hdtv. (From Tesco but it was fairly cheap - either way its still a hdtv). I have got the mini DVI to DVI and a DVI to HDMI. (So I have an adapter, then a cable). When I go on the HD channel I get a blue screen saying 'no signal.' My macbook picks up the TV in the system preferences > displays. I can provide screen shots or whatever if needed. Thanks in advance Charlie.
