Compact 1080p Laser Projector

The Optoma ZH420 is a Full HD 1080p DLP laser projector built for business and education environments. Its DuraCore laser light source provides 4,300 ANSI lumens of brightness and a 30,000-hour lifespan without lamp replacements. The unit is up to 34% smaller than earlier Optoma models and uses up to 50% post-consumer recycled plastics. An external power supply adds reliability and portability for flexible deployment.

Meeting Rooms Not Home Cinema

This projector suits offices and classrooms needing bright, maintenance-free 1080p presentation images with RS232, AMX, Extron and Crestron control integration. It supports 16:9, 4:3 and 16:10 aspect ratios and offers horizontal and vertical keystone correction of +/-30°. Buyers who need 4K resolution, high dynamic range cinema performance, or built-in smart TV platforms should consider a different category of display device.

1.16–1.49:1 Throw Ratio

The manual 1.3x zoom lens covers a throw ratio range of 1.16:1 to 1.49:1, projecting image diagonals from 31 to 322 inches at distances of 39.37 to 314.96 inches. This single optical specification determines whether the unit fits your room geometry and screen size. Verify the required projection distance against your installation space before purchasing.

Questions about this item

Should I choose the 4,300-lumen version or a lower-brightness model for a meeting room with windows?

At 4,300 ANSI lumens the ZH420 keeps 1080p images clear in rooms with ambient light; lower-lumen units will look washed out unless you can fully darken the space.

What does the 300,000:1 contrast ratio actually look like during a presentation?

The native 300,000:1 ratio produces deep blacks and sharp text on spreadsheets, while the dynamic 2,000,000:1 mode boosts dark-scene detail for video clips.

Which devices can I connect to the two HDMI inputs and will they support 1080p at 120 Hz?

Both HDMI ports accept 1080p signals up to 120 Hz vertical refresh, so laptops, media players and gaming consoles all run at full native resolution.
