Original title: Windows 10, dual monitors, DVI and HDMI
I have two monitors, an older Samsung (SyncMaster 245bw) and a new BenQ connected to an MD A8-7600 Radeon R7 adapter. There are 3 display ports on the computer - Analog (RGB), DVI and HDMI. The BenQ has an HDMI port, so I connect it that way. When I connect the Samsung through the analog port I can set up dual monitors and everything works fine. When I connect the Samsung through the DVI it goes black and the system promptly sees both monitors as one, but won't display anything except a black screen on the Samsung (so I can only see half the screen, displayed on the BenQ monitor). Rebooting has no effect.
Radeon settings sees both monitors no matter how they're connected, but Windows display settings refuses to see the Samsung when connected through DVI. It sees it just fine through Analog.
All drivers have been updated, btw.
Is it just that the Samsung is too old, or is there some work-around for what feels like a conflict in Windows. Is there a way to make the Radeon s/w control both monitors and take windows completely out of the equation?
