A DVI adapter connected to the monitor is present, yet no signal is being received.
The problem is straightforward but tricky. I needed to connect my DVI/VGA second screen using an adapter for my miniDP GPU. Following the guide about display cables, it mentioned that DP to DVI adapters should function at 1080p 60Hz, even passive ones. So I purchased one. Or at least I’m hoping it’s a genuine adapter; otherwise, I might turn it into a clothes hanger and use the monitor as a whiteboard. If that doesn’t work, what if I can’t pair my RX 580 with the RTX A2000? I’ve seen someone’s GTX 1030 fail to boot on an older i5 7400+RX580, which is concerning. But maybe... the GPU and RTX A2000 can coexist? I tested a friend’s GTX 1030 on their old i5 7400+RX580, and it didn’t even start. Perhaps it’s not possible at all.
It should function correctly, acting as a compact mini cable where orientation matters. I own many active and passive adapters; typically when downgrading, you don’t need an active one. It’s likely your cable is faulty or incorrectly labeled as DVI to miniDP. You might want to switch to VGA instead. If you have a DP to HDMI adapter nearby, you can use the HDMI to VGA connection your RX580 uses for testing.
Thanks for the clarification. The system seems to recognize the proper direction as "DP > DVI," which helps it detect the display correctly. Without a DP-to-HDMI adapter, it’s likely the issue lies with the interface itself rather than the cable type. Since you’re unsure about backward compatibility of the cable ports, it’s best to stick with what you have and avoid adding more adapters for reliability.
It might happen, but it's tough to confirm if companies aren't clearly listing port versions. I've needed several adapters; my M1 Mac switches between DVI, DP, and type-C because it connects to an older Apple screen. It usually works, though I sometimes have to restart the display, which feels more like a display problem than an output issue. It's basically an old Apple display from about ten years ago.
