Product Description
ViewSonic LSD400HD-ST – 1080p Short Throw Laser Projector
The ViewSonic LSD400HD-ST is a Full HD short throw laser projector rated at 4,000 ANSI lumens. Its 0.5 throw ratio produces a 100-inch image from just over a metre away, making it a strong fit for classrooms, meeting rooms, restaurants and golf simulators where space is tight.
A third-generation laser phosphor engine lasting up to 30,000 hours, a filter-free sealed optical engine and centralised LAN control keep running costs and maintenance low.
Key Features
- 0.5 short throw ratio – 100-inch image from about 1.10 metres
- 4,000 ANSI lumens – clear pictures in rooms with the lights on
- Full HD 1080p – native 1920 x 1080 on a 0.65" DMD
- 3rd-gen laser phosphor – up to 30,000 hours in Eco mode
- Filter-free IP6X sealed engine – dust-resistant with minimal upkeep
- Accepts 4K signals – HDMI 2.0 with HDCP 2.2
- H/V keystone and 4-corner adjustment – keeps the image square
- 360° and portrait projection – flexible orientation for creative uses
- LAN control – centralised management for estates of projectors
- Golf colour mode – enhanced greens and blues for simulators
Picture Quality
The 0.65-inch DMD gives high native contrast (3,000,000:1 dynamic) and DLP's consistent colour without yellowing over time. 4,000 ANSI lumens keep 1080p content vivid on screens from 40 to 300 inches.
Installation and Throw
With a fixed 0.5 throw ratio, the projector sits close to the screen, reducing shadows and glare: a 100-inch image needs about 1.10 metres. Horizontal and vertical keystone (±15°), four-corner correction and 0.8x–2.0x digital zoom fine-tune the picture.
Connectivity and Control
Two HDMI 2.0 inputs (HDCP 2.2), audio out and a 5V/1.5A USB-A port for powering the optional ViewShare casting dongle are included, with RS-232 and RJ45 for room control systems. Firmware updates can be applied over USB.
