If I connect two monitors to the graphics card via DVI to DVI one of the monitors doesn't turn on. It's not a broken port or broken cable as I've tried them individually and they work fine.
According to http://support.amd.com/en-us/search/faq/170 I should be able to connect all 3 monitors how I have it setup because all 3 monitors are the same, they're all 1920x1080 which isn't excessive in terms of resolution so that can't be the issue.
When I connect or disconnect the DVI cable Windows makes the "da ding" noise to tell me that a device has been connected/disconnected but nothing happens because of it. You can see the detection state: http://i.imgur.com/6300DDX.png
- DVI-D (Single Link) to DVI-I (Dual Link) (Monitor 1, working)
- HDMI to HDMI (Monitor 2, working)
- DVI-D (Single Link) to DVI-I (Dual Link) (Monitor 3, not working)
AMD Radeon R9 270x 4GB Ports:
- 2x DVI-Dual Link
- 1x HDMI
- 1x DisplayPort
ASUS VC239H Monitors:
- 1x DVI-D Ports
- 1x HDMI
- 1x VGA
I'm sure this should be able to be done, but if not...I know I should avoid using VGA to DisplayPort (I have an Active Adaptor from my old monitors) that never had HDMI or DVI ports
What would be the best adaptor to use:
- DVI to DisplayPort DVI (Monitor Side) to DisplayPort (GPU Side)
- HDMI (Monitor Side) to DisplayPort (GPU Side)
I would assume HDMI to DisplayPort would be the best one to pick, but I'm not 100% sure and what about the adapter being active or passive? Is there any need for an active adaptor, if so what would be the benefits?
