Description
The LSD400HD-ST brings ViewSonic's Luminous Superior lamp-free technology to short-throw installations, using 3rd generation laser phosphor light source and a 0.65" DMD DLP chip to deliver 4,000 ANSI lumens at native 1080p Full HD with a 3,000,000:1 contrast ratio.
Its 0.5 throw ratio produces a 100" image from just 1.1 metres, making it ideal for space-constrained installations such as golf simulators, exhibition stands and retail displays, while still scaling up to 300" for larger venues. Horizontal/vertical keystone with 4-corner correction and 360-degree projection allow flexible mounting angles.
The lamp-free design cuts power consumption by up to 59% versus comparable lamp projectors and removes routine lamp replacement, and the sealed IP6X optical engine keeps the unit dust-resistant for long-term, low-maintenance operation. Dual HDMI inputs, RJ45 LAN and RS232 support integration into managed AV systems, including Crestron and Q-SYS control.
