Optoma's ProScene 4K short throw: 3840 x 2160 on screen, 8,500 lumens and 7,200 ANSI from a DuraCore MultiColor laser rated 30,000 hours, a motorized 1.15x zoom (0.65–0.75 throw) and motorized lens shift. Optoma's figures for the shift disagree (its page says ±55% vertical and ±25% horizontal, its datasheet ±50% and ±18%); we plan on the smaller. A 100-inch image is about 4.7 to 5.4 ft from the screen, from the ratio. At $12,999 it is the most expensive projector we list. It combines 4K, a short throw and installation-grade brightness in one unit, which almost nothing else does, but for a home room BenQ's AK900ST is 4K at 6,000 ANSI lumens for less than half the price.

Who this is for
Honest match per persona.
Good for
- Showroom
4K, a short throw, 7,200 ANSI lumens and motorized lens shift in one unit: the projector for a very large showroom screen in a lit room, at a price to match.
Not for
- Cost-Effective Buyer
$12,999 for a projector.
- Recreational Player
Far more light and money than a casual room needs.
- Family Setup
A shared room gets 4K and plenty of light from the AK900ST for less than half the price.
- Space-Constrained
The throw is short, but the cabinet is 19 in wide and 17 in deep.

Room planner
See the Optoma ZK810TST in your sim room.
The planner draws it to scale with your room and your screen: where it mounts, how far the lens sits from the screen, and whether your swing or your shadow crosses the light. It opens in a sample room; put in yours.
