The Optoma ZK431ST is a true 4K UHD laser projector with a 0.496:1 short-throw lens, aimed at indoor golf simulators. Its 4,100-lumen DuraCore laser engine holds brightness for up to 30,000 hours with no lamps, and a dedicated Golf Sim color mode tunes skies, shadows and turf tones. The short throw keeps it close to the impact screen, cutting shadows and freeing hitting space, and Smart Fit uses a phone camera to square the image. Against lamp-based golf projectors it trades bulb changes for a sealed laser light source and adds 4K detail; the trade-offs are a fixed short throw that needs a close wall and a price tier above 1080p sim projectors.

The Optoma ZK431ST is a 4K UHD DLP laser projector made for indoor golf simulation. It has a native resolution of 3840 x 2160 (8.3 million pixels) and 4,100 lumens of brightness. It projects screens from 30 to 300 inches diagonal. A Golf Sim color mode tunes blue skies, shadows and grass-green tones for course rendering.
A 0.496:1 short-throw lens lets the projector sit close to the impact screen, which reduces shadows and club interference in tight rooms. Smart Fit uses a smartphone camera to detect the screen frame and automatically correct image alignment. Four-corner adjustment and ±15° horizontal and vertical keystone correction also help square the image to the screen.
The DuraCore laser light source is rated for up to 30,000 hours, with instant on and off and no lamps to replace. Input lag is as low as 8.6 ms, so the projector also suits gaming and general entertainment. It has dual HDMI 2.0 inputs.
