Disable Inject / Nvidia, that's not necessary for your new GPU any longer. It messes up the IORegistry, disabling all but two ports on your GPU.

old:
Samsung SyncMaster SA850 SMS27A850 connected with DVI
EIZO EV2736W connected with DVI

new:
Samsung SyncMaster SA850 SMS27A850 connected with DVI
EIZO EV2736W connected with ***DISPLAYPORT***
BENQ GL2450 connected with ***HDMI***

Connectors at GTX 950

DP1 - HDMI - DP2 - DP3 - DVI

EV2736W works well with DP1 and doesn’t work with DP2/DP3
BENQ GL2450 doesn’t work with HDMI

does anyone knows how to get BENQ GL2450 to work with HDMI as 3rd monitor?

thx

bye

Mirko
