Real installation spaces are rarely ideal — ceiling lights, air-conditioning vents, or excessive throw distance can all make it impossible to center the projector perfectly. Digital Zoom Extender solves this by extending the throw range beyond optical zoom, so the image fills the screen at the right size even from a non-standard distance. The new Digital Image Shift function lets you offset the projected image up to 10% up, down, left, or right via the remote control, compensating for off-center mounting without moving the projector physically. This also means the TMZ400 Series accepts the same mounting brackets as the conventional lamp-based PT-TW381R Series — swap in the new unit and use Digital Zoom Extender to realign the image, with no new construction required. Note: resolution decreases when using Digital Zoom Extender or Image Shift, some screen correction functions are unavailable, corner adjustment range is limited, and image size reduces to 80% when Digital Image Shift is active.
