Thanks for your answers. I was looking for a more suitable monitor in Amazon, and found this one:
https://www.amazon.com/Philips-Monitor-Bdm4350uc-42-5in-3840x2160/dp/B01CO2QT4M/ref=sr_1_1?ie=UTF8&qid=1489522338&sr=8-1&keywords=Philips+BDM4350UC%2F00
It is a 43 inches - 4k monitor. I suppose it will scale very well to 1920x1080 if needed, as it is exactly 4x a 1920x1080, or maybe I could run DCS at 4k with my 1070.
