Our take on the ViewSonic LS740-4K 4K UHD Laser Projector

The ViewSonic LS740-4K is a 4K UHD laser projector rated at 5,000 ANSI lumens, built for bright rooms where lamp projectors wash out. The laser light source is rated for 30,000 hours, so it is effectively maintenance-free for years of daily use. It suits meeting rooms, classrooms, houses of worship and large living rooms more than dark home-theater dens. Against 4K lamp rivals it trades a higher upfront outlay for far longer life and no lamp swaps; against premium home-cinema 4K models it gives up deep-black contrast and color tuning.

Questions and answers

Is the ViewSonic LS740-4K bright enough for a lit room?: Yes. Its 5,000 ANSI lumens is well above typical home projectors, so it stays visible with lights on or near windows. It is aimed at meeting rooms and classrooms rather than dark theaters.
How long does the laser last?: The laser light source is rated for 30,000 hours in standard mode. That is many years of normal use and means no lamp replacements.
Does it need a special screen?: No. It works on a white wall or any standard 16:9 projection screen. A matte white screen gives the most consistent image in bright rooms.
Is it good for movies at home?: It can show 4K movies, but its strength is brightness, not deep blacks. For a dark home theater, a dedicated home-cinema projector with better contrast is the better fit.
What connections does it have?: It has HDMI for laptops, media players and streaming sticks. It does not include a built-in smart TV platform, so you supply the source.
Can I mount it on a ceiling?: Yes. It is designed for fixed installation and can be ceiling-mounted. Its size and weight mean a sturdy mount is needed.
Where is the ViewSonic LS740-4K 4K UHD Laser Projector cheapest?: At Best Buy, for $1,799.99, as of our latest check.
