Our take on the Optoma ZU820TST Projector

The Optoma ZU820TST is a short-throw laser DLP projector built for large-venue installs. It puts 6,900 ANSI lumens of WUXGA (1920x1200) light through a 0.75-0.95:1 lens, so it fills a big screen from close to the wall, and the laser engine is rated for up to 30,000 hours with no lamp swaps. Powered focus and 1.3x optical zoom plus four-corner and horizontal/vertical keystone make it easier to align than fixed-lens short-throw units. It suits auditoriums, lecture halls, museums, houses of worship and simulation rooms; against lamp-based rivals it trades a higher upfront cost for brightness, long life and low maintenance, and at 27.78 lb it is a fixed-install projector, not a portable one.

Questions and answers

Is the ZU820TST a true 4K projector?

No. Its native resolution is WUXGA (1920x1200) at 16:10. It accepts 4K input and scales it down, so you get sharp 1200p, not native 4K detail.

How close can it sit to the screen?

The 0.75-0.95:1 throw ratio means a roughly 100-inch image needs about 6 to 8 feet of distance. The 1.3x optical zoom gives some room to adjust size without moving the mount.

How long does the laser last?

Optoma rates the laser light source at up to 30,000 hours. That is years of daily use with no lamp replacement, which is the main maintenance advantage over lamp projectors.

Does it need a special lens?

No. The short-throw lens is built in, with 1.3x optical zoom and powered focus. There is no lens swap, but you cannot change the throw ratio.

What inputs does it have?

HDMI is the video input, plus a 3.5mm audio line-out. There is no wireless LAN, so plan on a wired HDMI source or an external wireless adapter.

Is it bright enough for a lit room?

At 6,900 ANSI lumens it handles moderate ambient light on a large screen far better than typical home or classroom projectors. Very bright rooms will still wash out dark scenes.
