ATI HD 4890 hdmi display issue

[davebacca]

So i just got my i7 system put together and tried to hook up my hd 4890 to my tv/monitor via hdmi, but got nothing. I tried vga and it works and is what I am using right now but would prefer hdmi. Is there anything i need to do first? any help would be appreciated

Detail your system config. What monitor are you using? What is your OS?

I am having the same problem with my new I5 system. the 4890 worked just fine, other than a small border on all sides, until win7 32bit was replaced by win7 64bit, new 64bit drivers for the 4890 did not restore my HDMI out.
