Hello, I want to ask about 2 monitors setup on r9 390x. What port should I use? Is it DP and DVI?
Thanks in advance
Please provide more information.
The 390x can support a maximum of two displays using passive display connections which are HDMI/DVI. For the third monitor and beyond you will need to use native displayport connections, or active adapters. From what you have described, it should work with any of those connections. (DP/HDMI/DVI)
