    dual rx460 cards linked -- how do I unlink the cards

    lewgoins

      Hi,

       

      I installed 2 rx460 grapics cards each connected DVI to a monitor. OS is Win10 and with the generic drivers I had 2 monitors....about 10 minutes after I installed the Radeon drivers the screens blinked and the 2nd monitor went into standby. When I look at the Radeon settings it shows the 1st card as Primary and the 2nd as "linked". When I delete one card from the device manager I get both screens back for about a minute and then the screens blink and the 2nd monitor goes into standby again.

       

      Does anyone know how to unlink the cards to get 2 monitors back?

       

      Thanks,

      Lew
