Q: will this work with one 3440x1440 monitor and one 2560x1440 monitor? and will i be able to do over 60hz? they both do 100hz+

I'm fairly certain that you'd be pushing the limits of DisplayPort 1.2. Look at the total bandwidth being used of two monitors and if it exceeds roughly 24gbps, then the adapter won't handle it

Q: I have my eyefinity 3 monitor setup and want to add a forth, can I use this adapter, and is it active?

Note that previous answers were from 2015. Current AMD Radeon driver software (post-Castalyst) does not support MST, and NVidia has an article on their site explicitly stating their drivers do not support MST either. MST will still work in mirrored mode when in the BIOS and on Windows boot logo, because despite AMD and NVidia not supporting MST in their drivers, they DO still build the hardware to handle all of DisplayPort 1.4's feature set.

Q: What hz does this have with 2560x1440 monitors?

I have a 4 monitor setup, 2 of which go through the device. One at 3840x2160@30Hz, the other 1920x1080@60 Hz.

Q: Why is this not using the whole screen. Why is there about 3 inches of my screen not being used.
