Our take on the Optoma ZH450ST 3D Short Throw DLP Projector

The Optoma ZH450ST is a 1080p DLP projector built for tight spaces: its short-throw lens fills a large screen from close to the wall, so it suits small rooms, classrooms and meeting spaces. It is a laser-phosphor model rated at 4,200 lumens, which is bright enough for rooms with some ambient light, and it adds 3D support, Ethernet control and a healthy set of inputs. Against lamp-based short-throw projectors it trades a higher upfront outlay for long light-source life and no lamp swaps; against 4K rivals it gives up resolution but keeps brightness and installation flexibility. Buyers who need a big image in a small room and care more about brightness and longevity than pixel count are the core audience.

Pros
  • Short-throw lens gives a big image from close to the screen
  • 4,200 lumens handles moderately lit rooms
  • Laser light source avoids lamp replacements
  • Native 1080p with 3D support
  • Ethernet, HDMI, USB and VGA cover common sources
Cons
  • Only 1,800:1 contrast, so blacks look grey in dark scenes
  • 1080p, not 4K, at a price where 4K models exist
  • Short-throw optics can show corner softness and keystone limits
  • Built-in audio is basic; external speakers are better

Questions and answers

How close to the wall does it need to be?
As a short-throw unit it produces a large image from a few feet away, so it works in small rooms where a standard projector would need much more distance. Check Optoma's throw-distance table for the exact screen size you want.
Is it bright enough for a lit room?
At 4,200 lumens it copes with moderate ambient light, such as a classroom with blinds partly open. For critical viewing in a dark room, the limited contrast matters more than brightness.
Does it support 4K?
No. The native resolution is 1920 x 1080, though it will accept and downscale higher-resolution inputs. Rivals at similar brightness offer 4K, so choose this one for brightness and throw, not pixel count.
Do I ever need to replace a lamp?
No. It uses a laser-phosphor light source, so there is no lamp to swap; output dims gradually over a long life. That is the main running-cost advantage over lamp-based short-throw projectors.
What can I connect?
HDMI, VGA, USB and Ethernet are on board, plus 3D support. Ethernet allows network control in fixed installations, and HDMI covers modern sources.
Is the built-in speaker enough?
It is fine for presentations and casual use but thin for movies or music. Plan on external speakers or a soundbar for anything more than speech.
