I have a Asus EN9600gt graphic card with only 2 DVI ports. I use a DVI to HDMI adapter to connect my PC to my TV with a HDMI cable, and it does not work. I have test the adapter on my HDMI monitor, it is ok. My brother have a laptop (Nvidia 260M) with HDMI port, he can connect to my TV without any problem (the same HDMI cable). I have updated the display driver to the lastest from Nvidia. I am wondering why I cannot connect to my TV, everything just works fine.
