I recently tried connecting my PC to my TV to watch a movie and my GPU didn't output anything through HDMI. I use DVI for my monitor and it works fine.

I tried to find a solution and I found that I should enable HDMI output in the GPU BIOS. I have no idea how to get to it. (I read that you go there through normal BIOS but I can't find it in there anywhere.)

 

I also tried the HDMI output on my motherboard, that worked but it didn't output sound.

GPU: http://www.gigabyte.com/products/product-page.aspx?pid=4121#ov rev 2.0

I have the latest AMD drivers installed, including the HDMI one.

Can anyone please help me? How do I get to GPU BIOS?

Did you change window audio to use onboard HDMI?

I forgot. I will have to try that.

Any suggestions on how to fix the HDMI output on my GPU?
