Problem with HDMI in a new build

[adairusmc]

I just put together a new gaming HTPC for my living room, and had an issue with HDMI out of my radeon card this morning.

Specs are -
Gigabyte H87N-Wifi
Intel Core i5 4440
XFX Radeon 7850 Core Edition
Windows 8.1

I set up the machine using my Dell U3011 with a DVI port, but this is going to be working on my 52" TV in my living room. Never saw a single graphics problem on the DVI plug when setting up windows on the dell, though admittedly I did not try HDMI at all there.

The HDMI cable I know works fine because it is the same one I have been using for years on my old HTPC.

What is happening, is if I have the HDMI plugged into the Radeon card, it will show me the BIOS/UEFI screen, but when it loads windows it goes blank. I have tried the newest AMD drivers, reverting back to an older driver, and also trying out the beta driver that is listed on their site currently. Nothing makes the Radeon HDMI work directly off the card in Windows.

If I plug the HDMI directly into the onboard HDMI port for the intel graphics, it works, and the catalyst control center can even detect the display. I have tried disabling the onboard graphics in the BIOS, which did not help, but I was still trying to run it directly off of the card at that time and didnt try it through the motherboard HDMI (I would assume with the intel graphics it would not work).

Is there something I am overlooking here, or is this like a switchable graphics solution where it gives the motherboard HDMI priority but still using the Radeon for GPU use?

Thanks for any input.

I believe there is something wrong at software side.You can try to reformat hard drive and Install new OS.

I actually tried a reformat a couple of times, and HDMI works fine until you install the AMD drivers - and I tried several drivers.

I sold the card locally and had a GTX660 superclocked card delivered on Saturday, and that fixed the issue.
