Graphics Card and is Dual Screen Working?

[gateway69]

Wanted to start a poll and maybe get a list of people who have working Yosemite installs with Dual Monitor.

Please post your card and if you have dual monitor support working and maybe what you did or guide you used.

Edit: If you have a R9 290x card working with dual screens I would love to hear how you did it what settings in clover to adjust.

R9 290x
Dual Monitor support: No, blacks both monitors when plugging in another one
UniBeast --> MultiBeast (couldn't really get clover to work).

Everything else works great accept for iMessage but thats known with MultiBeast.

What cards are you Nvidia guys using?

ATI/AMD 5770 XFX single slot.
Monitor 1: Apple Cinema Display 27" LED via mini Display Port
Monitor 2: 32" 768p LG TV via DVI-to-HDMI cable (mainly just to test, resolution is too low for anything useful).

Nvidia GT 640 both screens are BenQ via DVI.

ATI 5870 works fine - only issue is that Yosemite seem to forget the monitor profile regularly. But I think that's a Yosemite issue, not anything configuration related.

MSI AMD R9 280(non-x) 3GB

Both Mini-Displayports work driving Apple 27in Cinema Displays.
HDMI also works, have not tested in a triple monitor situation.

All was working Out of Box.

Very pleased, and surprised how well it worked.

GTX 980 4GB - Dual Screen Not Working

1x LG IPS234 (DVI to DVI)
1x Samsung B2330 (HDMI to DVI)

Only the DVI is working and I can't test the DP.

Currently running the Samsung off integrated graphics.

2 monitors and 1 50" Plasma. I did have to buy an ACTIVE Displayport-->HDMI adapter dongle to make the 3rd display work but that is normal for my card.
