Looking for a Monitor to mount next to my dell S2417DG

I just upgraded to the S2417DG and am loving it but now I want a second screen that I can mount next to my S2417DG with similar aspect ratio's/colors for internet surfing, videos, non-gaming stuff. I'd buy the S2417DG again but I feel like two G-sync monitors would be pointless if I'm only going to be gaming on one. I was looking at the U2515H. Any advice or recommendations would be appreciated.

Thanks!
