Dell U2718Q
The Dell U2718Q is better than the Dell U2717D. The Dell U2718Q has a higher native contrast ratio and supports HDR, as well as having a higher resolution screen that allows you to see more details or get more done. The U2718Q has much lower input lag regardless of input resolution, great for gamers. The Dell U2717D has no visible flicker and better reflection handling.
