Hi guys

hope you can help me here. I am planning to buy some Dell Latitude E7450 for our company with a Dockingstation and some Dell Ultra Sharp 24 Monitor - U2415 . Goal is to use the E7450 with the dockinstation and connect 2 Dell U2415 Monitors. the question here is. what kind of cables do I need? do I need to purchase 2 regular display port cables? it the resolution going to work with that combination?
