Professional 4K UHD Laser Projector

The OPTOMA ZK400 delivers 4000 ANSI Lumens brightness and native 4K UHD resolution for business environments. Its DuraCore laser light source provides dust-resistant operation and consistent colour performance. The unit suits meeting rooms, classrooms and digital signage installations requiring reliable, high-contrast projection without lamp maintenance.

Flexible Installation Features

Three HDMI ports and one USB-A input cover most source devices while 360° positioning allows ceiling, table or portrait mounting. Keystone correction and corner alignment tools simplify geometry adjustment on uneven surfaces. The 1.5 to 1.66:1 throw ratio offers placement latitude, though installers must verify the exact distance for their target image width before fixing the mount.

Image Size Range and Brightness Limits

The projector scales from 33 to 300 inches diagonal, covering huddle spaces up to large conference halls. At 4000 ANSI Lumens the picture stays visible in moderately lit rooms, but very bright ambient light or screens beyond the maximum diagonal will reduce perceived contrast and wash out detail. Users needing larger images or higher ambient-light rejection should evaluate alternative technologies.

Questions about this item

How do I confirm the ZK400 is delivering its rated 4000 ANSI lumens after installation?

Use a calibrated light meter at the screen centre; the reading should match the 4000 ANSI lumens specification when the projector is in its brightest preset.

Which cables and accessories are included with the ZK400 and what must I source separately?

The box contains the projector, power cord, remote control and documentation; HDMI cables for the three HDMI inputs and any USB-A peripherals are not included.

Which throw-ratio version of the ZK400 suits a room where the lens-to-screen distance is fixed?

The ZK400 has a fixed 1.5 to 1.66:1 zoom lens; choose a mounting position so the calculated throw distance fits within that range for your desired image width.
