Compact single-chip native-4K RGB laser versus three-chip cinema architecture.
Heimdall keeps the projector compact and flexible with single-chip DLP RGB laser. Freya moves into a three-chip cinema architecture with different optics, installation demands and system scale.
A Freya-class solution should be justified by the room: screen width, target luminance, colour target, projection-room strategy and budget for the complete optical system. Heimdall can be the more elegant answer where compactness and placement flexibility matter.
Heimdall+ is the easier fit where compactness, HDMI 2.1 and broad optics matter. Freya is the step into three-chip cinema architecture, higher mass and a projection-room mindset.
