Aye, the S27A950 would work just as well as the 750D - since it also has a HDMI 1.4 port (see here).
However, it is more expensive and you could just as easily connect your PC to the 750D monitor via the Display port connection to get the 1080p@120Hz signal.
When I mentioned 750D, I should have been more clear as there is also a 27 version of the 750D - the S27A750D which is around £50 cheaper than the 950D.
