LG UltraFine 4K and 5K displays are the new Apple monitors
 

In case you weren't aware, Apple tends to release new monitors to go along with new devices. The refreshed MacBook Pro announcement yesterday didn't include any monitors with Apple's name on them, though. The honors were given to a pair of LG displays called "UltraFine," which the company says were designed specifically for the new MacBooks. The UltraFine displays are available in 21.5" size with DCI 4K resolution and as a 27" variant with 5K resolution.
