Solved HDMI with just one Monitor

I connected my computer to the monitor using the HDMI cable, but the screen went black/blank,
I am under impression that HDMI is for TV or a second monitor! However my friends tells me HDMI is just new generation of graphic connection, and replace the older cables, and I have to set up my computer and drivers properly! I have tried everything, but still get the black screen , when using DVI everything works well! Any idea what to do?

Have you selected HDMi input on the monitor itself?

The only difference between DVI and HDMI is that HDMI carries the sound. It's a full audio/video cable in one.

Of course I have, connecting the HDMI cable for VGA car to HDMI, as well I tried without the car, using the on board HDMI . Same black screen shows up.

kujiransan,
This would be a good time to add your system specs.....but of course you knew that.

Hi there thanks to all of you, the problem was that the monitor came with HDMI cable only but its default was not auto switch to HDMI/DVI , I checked the menu and the default was DVI, wonder why they do that at the factory! After all one has to get a DVI cable and connect the monitor then switch to HDMI then use the cable!
Once again thank you for you help! Very much appreciated!
