What resolution does the ZW410UST project?

It projects WXGA, 1280x800 pixels, in a 16:10 aspect ratio. That suits presentations, documents and classroom software better than 16:9 video.

How close to the wall does it need to be?

As an ultra short throw model it sits inches from the wall or screen to make a large image. Exact distance depends on the image size you want, so check Optoma's throw chart for your screen.

How long does the laser last?

Optoma rates the laser light source at roughly 20,000 hours. That covers years of typical classroom or meeting room use without lamp changes.

Is it bright enough for a lit room?

At 4,000 lumens it handles rooms with blinds open or lights on. Very bright, sunlit rooms will still wash out the image, as with any projector.

Does it work for home theater?

It can, but WXGA resolution and a 16:10 panel are not ideal for movies. A 1080p or 4K ultra short throw model is a better fit for film and TV.

What connections does it have?

It offers HDMI and typical control and network ports for classroom and AV installations. Confirm the exact port set for your source devices before buying.
