High-brightness 4K UHD laser projector
The ViewSonic LS740-4K delivers 5,000 ANSI lumens at a native 3840 x 2160 resolution with a 3,000,000:1 contrast ratio. Its laser phosphor light source provides up to 30,000 hours of maintenance-free operation without lamp replacements. A 1.6x optical zoom and 360-degree projection support flexible placement in classrooms, conference rooms or home theaters. The unit operates on 100-240 VAC power and includes a remote control.
Replaces lamp-based installation projectors
Switching from a traditional lamp model cuts energy consumption by up to 49% and removes the recurring cost and downtime of lamp changes. The jump is worth it when a venue needs consistent 4K brightness in ambient light and wants to minimise long-term maintenance. A throw ratio of 1.4 to 2.24 covers distances from 0.93m to 14.88m, so the same unit can serve small meeting rooms and large halls alike.
Suits integrators needing flexible 4K installation
This projector fits installers who require horizontal and vertical keystone correction plus 4-corner adjustment for off-axis mounting. Golf simulators benefit from a dedicated Golf Mode that optimises colour accuracy for fairways and greens. Buyers who need built-in audio should look elsewhere, as the unit has no speakers. Those requiring ultra-short-throw placement or portable battery operation will also need a different form factor.
