my setup uses a receiver for audio, which is driven by HDMI from my VGA (r9 290). Then I have a monitor over DVI to HDMI.
Every time I try to set 50 Hz refresh rate in my monitor settings, my system won't comply. Is there some kind of "use this HDMI for audio only" mode? Ideally, I would like to run custom refresh rates with my display in the future, or use a freesync monitor while keeping the HDMI audio out. I am on win 7 pro x64.
