Windows 7 control panel sees, recognizes and identifies all 3 monitors. In fact I thought I was done!. But it only lets me extend any two at a time ; not all three at once. Solutions
From searches to date, I read quite a bit so far - all frustrating:
Option 1 - use a passive or active DP adaptor - but not applicable here as I dont have a DP port.
Option 2 - add a cheap second video card - but many unanwered questions -
a) If I get a second video card - must it have the DP port for all this to work? I assume yes, given I dont have any DP ports now, and three conventional ports dont seem to do the trick.Option 3 - Throw out the Dell OEM video card and replace it with something new ( like what?) with DVI, HDMI and DP ports (at what cost?) and what type of DP adaptor?
b) If yes to needing a DP port, the what type of DP adaptor do I need to get?:
- DP to VGA passive?
- DP to VGA active?
- DP to DVI passive?
- DP to DVI active?
c) How do I set it up? Any two monitors on the orignal OEM card (no DP) and one monitor on the new card (via DP)?
d) Regardless i have been unable to find such a card on the market that is "a cheap second video card". has a DP port, and is not a X16 card ( that slot is filled).
Option 4- Give up. Abandon the project and stick with two displays ;This will be my only option if I cannot find a another solution.
Again, sorry for the long post but I am out of ideas.
