Overview

The InFocus IN128HDSTx is a short throw DLP projector designed for environments where space between the projector and screen is limited. With a native 1080p resolution and 3500 lumens of brightness, it delivers clear, vibrant images in classrooms, conference rooms, huddle spaces, and home theater setups where a traditional long-throw projector simply would not fit. The short throw lens allows it to project a large image from just a few feet away, which also has the practical benefit of keeping the projector beam out of the presenter's eyes.

The IN128HDSTx distinguishes itself from basic projectors with built-in networking capabilities, enabling IT administrators to remotely manage, monitor, and control the unit over a network — a significant advantage in institutional deployments with multiple projectors. The 15000:1 contrast ratio produces solid black levels and a dynamic range that enhances both text-heavy presentations and video content. At just 5.1 pounds, it is light enough to ceiling-mount without heavy-duty hardware or to carry between rooms as needed. The built-in speaker handles basic audio, while the 3.5mm output allows connection to a dedicated sound system for larger audiences.

Pros & Cons

👍 Pros

  • Short throw design projects large images from just a few feet, ideal for small rooms and tight installations.
  • 3500 lumens of brightness performs well in rooms with ambient light, unlike dimmer projectors.
  • Native 1080p resolution delivers sharp Full HD detail for presentations and video content.
  • 15000:1 contrast ratio produces deep blacks and vivid colors for a DLP projector in this class.

👎 Cons

  • DLP technology can produce a visible rainbow effect that bothers some viewers.
  • The built-in speaker will be insufficient for larger rooms, requiring external audio equipment.
  • At 1080p, it lacks the 4K resolution that some competing modern projectors now offer.
