In theory, yes. With the three MacBook Pro's and LG Ultrafine 4K displays we bought, unfortunately the MacBook Pro's either don't recognise them as having that display resolution, or they can't output at that display resolution. They still look great. Just not 4k.
My MacBook Pro works with the 5k just fine.
MacBook Pro’s can defo output at 4K, are you sure you’re not getting mixed up with actual and scaled resolutions?
