Holography is theoretically not necessary for a full 3D display. A [[light field display]] is a type of display that can show full proper focus. 3D displays can be world-fixed, like mounted on a desk, or they can be head fixed, like built into a [[VR headset]].

There are multiple ways to get a 3D display to show proper focus, thereby giving proper [[accommodation]] cues. A light field display sends focal stacks of images based on [[ray]]s to the eye.
