Connecting non Apple monitor to Macbook Pro

I'm planning to buy standard 13-inch MacBook Pro (2017) without Touch Bar or Touch ID features; I plan to use this for basic computing task and web development/programming. Does connecting a monitor to MacBook Pro via display adapter lower the refresh rate, or should I just find a non apple monitor that has thunderbolt port? I don't want to have to deal with any performance issues while coding and compiling or render images/graphics in Adobe CC. I'm very new to the whole Mac ecosystem, so all advice is appreciated.
