- 1080p 4LED business projector
Description
LH730 is designed for presentations, spreadsheets and shared video in a business room. Native 1920 × 1080 resolution gives you a widescreen workspace, while the LED light source avoids a conventional replacement lamp. BenQ includes picture modes for different presentation material rather than expecting every slide and video to use the same settings.
Placement remains important. The 1.3–1.56 throw ratio means the lens sits farther from the screen than a short-throw projector. Measure the room against the intended image width before deciding on a shelf or ceiling position. Its support for a 4K input signal does not change the projected native resolution to 4K.
Features
- Full HD image: Native 1920 × 1080, 16:9 projection suits widescreen office content.
- 4LED light source: Rated life is 20,000 hours in Normal or up to 30,000 hours in Eco mode.
- Optical zoom: The 1.2× zoom provides a limited range of physical placement adjustment.
- Flexible geometry: 2D keystone, corner fit and digital shrink help with final image alignment.
- Dual HDMI: Two HDMI 2.0b inputs support switching between connected sources.
- Integrated sound: A 10 W speaker provides a basic audio option for presentations.

Estimate lens-to-screen distance
Throw distance is image width multiplied by throw ratio. For a 100-inch diagonal 16:9 image, the width is approximately 87.2 inches, giving an approximate lens-to-screen range of 9.4–11.3 feet. This is a planning calculation; confirm the exact screen, mounting height and projector calculator before installation.

Common questions
Is the projected image native 4K?
No. The native image is 1080p. Compatible 4K input is processed for the Full HD display.
Does it need lamp replacements?
It uses a 4LED light source instead of a conventional projector lamp. Rated source life is not a guarantee that all components last that long.
Can digital keystone replace correct mounting?
It can help align the image, but starting with correct physical placement is preferable for preserving usable image detail.
Is it a short-throw model?
No. Use the 1.3–1.56 throw ratio to check whether the available room distance fits.
