One last thing, what do you see in the Primary Display tab?
I took the third monitor off line by unplugging entirely. I then went into NVIDIA settings and checked them for position and monitors 1 and 2. Then I went into Win10 display settings and made sure that I was in extended display mode. Everything seemed to check out. HOWEVER, when I then opened DaVinci Resolve, still not being able to access dual screen I checked to see what the primary display read... and I got the following (see photo). I'm only getting "generic monitors" listed. I can switch them back and forth for the primary/secondary in that menu but obviously it is not recognizing the specific monitors, Dell U2717D and Asus VW246H.
FYI... The third monitor that got unplugged was hooked up via display port. The two remaining monitors are on HDMI. The Dell has a display port. Perhaps I should try using that instead of HDMI?
EDIT/UPDATESince posting this reply, having taken the third monitor offline, I used the display port cable that the 3rd monitor used, and plugged it into the Dell instead of the HDMI cable that it was using. Still no change in status in Davinci. The following screenshot is still the same.
Based on your screen shot it seems that DaVinci should be able to recognize the specific monitors, but seems to fail to do that. Perhaps that is the issue? But if so, what is the fix for that?
