Looking for laptop that can handle short 4K editing..

Solution
For 4k videos I generally recommend a laptop with a quad core i5 CPU. Like the Dell XPS 15 9550 (2016 model) or the new Dell XPS 9560 (2017 model). The thin bezel on this 15.6" laptop make the overall size of the laptop similar to a 14" laptop and I believe the non touchscreen versions weighs in at 4lbs.

An i7 would be better because of Hyper Threading, but going for an i5 is less expensive and should be fine for short videos.
