I am running a simple dual monitor setup. Both support DP and were connected without issue before the 16.7.3 update. I am running a Sapphire R9 390x card with Windows 10. My secondary monitor is detected via DP but it won't actually turn on. I have moved it from one DP to another on the card wit no change. I am able to connect it to the card using HDMI and see the monitor so it appears that is must be an issue with the latest driver update. Is anyone else seeing this issue?
