Our take on the Viewsonic 4K UHD Laser Home Theater Projector LS901-4K

The ViewSonic LS901-4K is a 4K DLP home theater projector built around a laser light source rated at 5,500 ANSI lumens. That brightness is far above typical home theater projectors, so it holds up in rooms with some ambient light and on larger screens. It supports HDR10 and HLG, has vertical keystone and zoom for setup, and includes built-in speakers and a 12V trigger for screens. It lacks 3D and horizontal lens shift, so placement needs care. It suits bright multipurpose rooms and big-screen sports or movie use more than a light-controlled dedicated cinema.

Questions and answers

Is the LS901-4K bright enough for a room with windows?
Yes. At 5,500 ANSI lumens it is much brighter than most home theater projectors, so it stays usable with some ambient light. In a dark room you will likely run it in a lower brightness mode.
Does it support 3D?
No. The LS901-4K does not support 3D playback, unlike some competing home projectors.
How long does the laser light source last?
ViewSonic rates the laser for roughly 20,000 to 30,000 hours depending on mode, far longer than a lamp. Brightness slowly declines over that life rather than failing suddenly.
Can I place it off-center from the screen?
Only partly. It has vertical keystone correction but no horizontal lens shift, so a centered position is best. Large horizontal offsets will distort the image.
What inputs does it have?
It offers HDMI, VGA, RS-232 and USB-A, plus a 3.5mm audio output and a 12V trigger. There is no 3D sync port.
Does it have built-in speakers?
Yes, it has built-in speakers for basic use. For a home theater, external audio through the 3.5mm output or an AV receiver is the better choice.
Where is the Viewsonic 4K UHD Laser Home Theater Projector LS901-4K cheapest?
At Newegg, for $2,254.99, as of our latest check.
