Advise on buying for multi-monitor setup

[TheForumTroll]

I'm looking to upgrade both me and my girlfriends displays, but since we got multi-monitor setup (old BenQ GW2670's) they can't be too expensive, so instead of just throwing money at expensive screens and hoping for the best any advice on good-for-gaming displays matching the following without breaking the bank would be very much appreciated:


Must have: 1440p, 120hz+, 16:9, FreeSync, low input lag
Bonus: Both HDMI and Displayport, good brightness (there's a window behind me), flicker-free, good colour reproduction
Not needed: Speakers, G-sync, 4k
Usage: 70% gaming, 20% programming, 10% browsing HardForum
Price: I don't really know how low you can go and get the above specs without getting too low quality... $400-ish?
Idea: ViewSonic VX2758-2KP-MHD ?
