商品問答

What throw distance do I need for a 100-inch image?

The projector covers a throw distance of 47.64 to 389.76 inches, so a 100-inch diagonal falls well within that range.

Can I connect a gaming console and a PC at the same time?

Yes, there are two HDMI 2.0 inputs, so you can keep both devices connected and switch between them.

How long will the lamp last if I use the Eco setting?

In Eco mode the lamp is rated for up to 10000 hours before replacement is needed.
