The 5.5-inch 1080p screen integrated with the Phantom 4 RTK's remote controller has 1000 cd/m2 of brightness, which is more than twice as bright as conventional smart devices. It makes bright, vivid colors easily visible in direct sunlight. With this screen, a mobile device is not required, simplifying pre-flight preparations, and further reducing video lag. Integration of a Micro-SD card slot and 4G USB Dongle port allow images to be edited instantly. Lastly, the battery supports hot swapping and has an embedded loudspeaker.
