    RX 460 does not detect second display on DVI


      Had problems getting dual monitors to work when I installed RX 460 on Win 7 PC


      It was my fault -- installed the card and ran setup forgetting I had not moved second monitor cable off of CPU onboard video-out connection on motherboard


      I tried to move it afterwards and rerun setup but it didn't work so I reconnected it to onboard video and had second monitor working that way


      OK so months later, I had to replace primary display (bad caps)


      New monitor worked as expected, months elapsed, driver updates happened, all with secondary monitor hooked up via onboard video


      (Second monitor is a Samsung HDTV/PC Display with speakers (was relying on for audio, but that stopped working after driver update I think) )


      So .. one of my apps (Sketchup) was crashing on startup which incentivized another try at sorting this out for real


      Moved secondary display cable to the RX 460 DVI-D, reinstalled AMD drivers from original installation disc, restarted PC, at bootup, second monitor mirrors onscreen display during bios initialization, then goes blank


      Right click display properties only "sees" primary display


      It's not seeing monitor on DVI-D connector .. it is a decent quality DVI-D cable with gold plated connectors purchased 2016


      I could try buying another cable (displayport) new monitor has DP and HDMI connections (Samsung has DVI-D and HDMI)


      but before trying that figured I'd contaminate a support forum with my inept warblings // cheers and thanks



      I ran AMD uninstaller. After reboot, both monitors work (mirrored display).

      Ran setup from video card installation disc, after restart second monitor not findable. How fun.


      **UPDATE 2**

      Got latest video drivers from AMD support, selected the recommended latest (not the optional), minimal version, "clean install" .. system restarts, both monitors working (mirrored like before) ==> popup, appcrash, details:
