I have the following setup:
A Windows 7 64 bit PC with a Intel core i7 on a ASUS Z87-K motherboard, connected via DVI to a monitor and via HDMI to a Onkyo TX-NR626 receiver. The motherboard has an Intel HD Graphics 4600.
This setup was working fine.

After a shortcircuit in my home the HDMI output of HD Graphics 4600 isn't working anymore. The DVI output is still working.

I first checked if the Onkyo input was working by connecting a PS3 to the same HDMI input and this is the case. So my first thought was that the hdmi output of the motherboard was broken by a voltage spike due to the shortcircuit.

I had a ASUS Radeon 5770HD card lying around so I decided to plug this into the PCI-E port of my motherboard. The DVI output of the 5770 is working but the HDMI is not. I thought this was strange because the 5770 wasn't plugged in at the moment of the shortcircuit.
I tried to connect my tv to the computer with a dvi to hdmi adapter and this is working, both on the Intel HD graphics and the 5770.
Next I reinstalled the drivers for both cards. Not the solution. Next thing I tried: booting in a linux live disc. Same behaviour in ubuntu studio: DVI is working, HDMI is not.

The HDMI output of the 5770 worked in my previous PC. I tried different HDMI cables.

Anyone an idea what the problem can be. I really don't understand why the 5770 doesn't work.

The HDMI technology on your Motherboard has probably packed in.

HDMI technology is not only in the GPU but the Motherboard also,the short-circuit of your board must of affected the the PCI-E expansion slot and damaged the HDMI data transfer.

the only solution i know is buy a new Motherboard or use the DVI

Or i could be wrong.....
