My Radeon 5770 has 2 DVI, 1 HDMI and 1 DP socket, the following are used:
1 DVI digital 1 DVI -> DSUB analog
Now I want to add another monitor with an analog DSUB connection (a 15" one, not much space left on my desk).
The question is: Can I do this? I have searched high and low and people only had different combinations yet. What I want to know is WHICH combinations are actually possible? I know one thing: The card only has two frequency providers for HDMI/DVI, so only two digital HDMI/DVI monitors are possible. But I do not know about how many analog ones are possible.
I also heard about passive display port adapters for D-SUB. Do they work in this case? This is the only socket I would have left right now. If there is any other possibility (like getting one DVI monitor through DP through a passive adapter or something?), please do tell. What I need one digital DVI and two analog D-SUB monitors.
