HDMI not working on HD 5870 EF6

post #1 of 5
Thread Starter 
I want to connect my rig to my 42inch 1080p HDTV. I wish I could just use VGA, but unfortunately Sapphire sent me 2 DVI to MiniDP dongles instead of one DVI and one VGA dongle, so for now I have to use HDMI. \

Problem is, I can't get either my monitor or HDTV to recognize a signal on HDMI. DVI works just fine for my monitor, but my HDTV doesn't have DVI, it has VGA of HDMI only.

The drivers are current. This system was put together not even a month ago. Is there something I have neglected to do? I certainly haven't changed anything from stock (threw out the OC profile, extra heat wasn't worth the negligible performance gain).

EDIT - Just found out I was wrong and they do not include nor do they even make a VGA to MiniDP adapter... which they should if you ask me. So I need to get the HDMI working.

They really shouldn't make a Mini DP-VGA adapter... It's pretty old tech.

Check all your connections. Try all 6 Mini DP ports. Make sure the HDMI cable works. Plug something else HDMI into the TV. Troubleshoot.

Most HDTV's feature a VGA port instead of DVI. For that reason, I think they should make the adapter.

I have 2 other HDMI devices connected to the TV (BD player, Sat. receiver). I have tried multiple ports on both the TV and GPU. What else to troubleshoot?

Are you using the HDTV as the primary display or trying to use it as a secondary?
I was able to hook up my HDTV to my card through the DP port using a active DP adaptor to DVI-D to HDMI cable...

If its being used as a secondary than you might have to go into the CCC and enable it manualy.

You could also get a DVI->HDMI cable if you are still having problems
