The Optoma 4K400STx delivers true 4K UHD resolution at one of the most competitive price points in the short-throw projector market. With 4,000 ANSI lumens and a tight 0.5:1 throw ratio, it fills a 100-inch screen from just over 4 feet while maintaining brightness even in rooms with ambient light. The ultra-low 4.0ms input lag makes it particularly appealing for competitive golfers who demand instant response from their simulator software, while four-corner correction ensures perfect alignment in challenging room setups.
