OPTOMA 4K400x 4000-Lumen UHD 4K DLP Business Projector

Professional 4K UHD projector for bright rooms

The OPTOMA 4K400x delivers 4000 lumens and true 3840 x 2160 resolution for classrooms, conference rooms or offices where ambient light cannot be fully controlled. Dual HDMI 2.0 ports, USB-A power, RS232 and a 12 V trigger simplify integration with existing AV control systems. CTA-approved 8.3 million on-screen pixels provide four times the detail of Full HD.

Replaces dimmer 1080p units when detail matters

Upgrade from lower-resolution projectors when text clarity, spreadsheet grids or fine graphics must stay sharp on screens up to 300 inches. The 1.5 to 1.66:1 throw ratio suits standard long-throw installations without moving furniture. HDR10 and HLG support future-proofs the display for high-dynamic-range content sources.

Handles daylight presentations and 240 Hz gaming

4000 lumens keeps images visible with lights on, while 1080p at 240 Hz and 4.2 ms input lag serve fast-pc gaming or motion-heavy demos. Native 4K at 60 Hz covers cinema and detailed data work. Buyers needing lens shift, short-throw placement or built-in streaming apps should evaluate other models.
