I have a new HP laptop model DM4-1165x running Win7 64-bit.  Trying to connect to a Sony Bravia TV using an HDMI cable so my laptop will display on the TV.  I thought it would plug & play.  When I plugg the HDMI cable into my PC, my PC screen goes blank and the TV displays 'unsupported signal please check device output'.  If I unplug the HDMI, then the screen comes back on the PC.  I go into display-screen resolution.  I can choose to extend monitors and have 2 displays, set the resolution to one supported by the TV, click apply.  Then plug in the HDMI and same problem.  I have tried various resolutions but my PC screen always go black.

Any ideas?
