Triple Monitor set up not working anymore.

Hello. I recently got a new video card (Sapphire AMD RX 580 8GB DDR5) after having upgraded from my old Gigabyte Nvidia Geforce GTX 650 ti 2GB. Originally I had a three monitor setup (one monitor using HDMI, one using VGA and another using DVI). When I put the new graphics card in, only two of my monitors worked (and my third monitor was being detected by the PC but not receiving any signal, now it is not even being detected). I have connected the three monitors to my new graphics card like this:
Monitor 1: HDMI
Monitor 2: DVI
Monitor 3: HDMI

Monitor 2 is the one that isn't working and it is a Samsung SyncMaster 2232BW.
Monitor 1 and 3 are working and they are the same model - Phillips 227E.


I was using the same monitors with my old graphics card too.

Currently, the three monitors seem to be detected by the PC, though monitor 2 says "Check Signal Cable" on the screen."

Nevermind, I managed to fix it. The problem was that since I'd previously used VGA on that monitor (which is analogue), the monitor was still looking for an analogue input. I changed it to look for a digital input (DVI) and it works now.
