Hi, I'm waiting for my 2018 MBP to arrive and I'm thinking of getting a 4K monitor to go with it. Because I don't have much experience with newer laptops, using a MBP 13" from 2009, I'm not sure what to expect. I know from specifications what the new ones can/will handle, but not how good. For my case I wonder if the fans will go wild or if the experience will by laggy for normal tasks and 4K YouTube videos, Netflix. I don't think I could stand the fans going wild for such things. I don't have the possibility to visit an Apple store, so if there is anyone here with this combo, MBP 13" i5 2018 + 4K monitor. How is your experience? Any input is appreciated, thanks!
