The rear of the camera is adorned with an articulating 3 inch LCD. This is a TFT LCD display with 1,228,800 dots. Dots? What are dots? TIL a dot is (usually) a third of a pixel.
In short, less than an iPhone (326 for the iPhone 6), but certainly high-density. And that's good, considering that no mirror means no optical viewfinding.
The left side of the camera body houses plenty of I/O options—an HDMI micro connector, 3.5 mm stereo microphone and headphone terminals, and a micro-USB connector.
