I have an HP Pavilion 6320f w/2709m monitor connected to my 720p projection HDTV (2007) with an HDMI cable. No signal is detected by Windows, HP Source Control and the NVIDIA Force Television Detection on restart is greyed out and useless. Yes, I have the cables connected correctly and my TV on the right input which does work with an S Video Cable from a laptop. Any help will be appreciated. I really don't want to watch movies on S Video. Thanks in advance.
