Why HDMI is Not Working for my Monitor?

[THpubs]

I just bought a new 23inch Samsung Monitor (S23B370). It have full HD support and also have an HDMI port. I bought a HDMI cable which have HDMI on both ends. I have a VGA (Nvidia 210) which also have an HDMI port. I connected the monitor's HDMI out to the VGA's HDMI port with the new cable and booted. Nothing came. I even set the Monitor's settings to HDMI. But nothing happened. It says check display cable. Why is this? How to fix it? Have I done something wrong?

You have to use your graphics cards hdmi port to power the video, then in sound set the default playback device to hdmi...
