Radeon R-9 390x - is there a simultaneous output using both the display port and HDMI together with audio? I would like to use an HDMI capture box while simultaneously using the display port with my current audio setup with external Bose speakers in Windows 10. 5.1 or 7.1 audio not needed for the capture box. Would I need a display port splitter and then a display port to HDMI cable? Or can I use the HDMI port directly and not cancel out the display port output?
