Optoma UHZ55 vs Optoma UHZ35ST
Every published specification for both, with the brightness standard shown beside each figure and the screen geometry worked out from each maker’s own throw ratio. Rows where the two differ are tinted.

Optoma
Optoma UHZ55
Optoma's mainstream laser home-theater projector: 3,000 ANSI lumens, a 30,000-hour laser, a 1.3x zoom with a little vertical shift, and 20 W of built-in audio.
Best for: A first laser projector for a mixed-use room under $2,000

Optoma
Optoma UHZ35ST
A 0.50 throw ratio puts a 100-inch picture on the wall from about three and a half feet, which is closer than anything here except the true ultra-short-throws.
Best for: A gaming room barely deeper than the screen is wide

Optoma UHZ55: what it gives up
- HDMI 2.0 caps 4K at 60 Hz
- Optoma's built-in app platform is not licensed Google TV, so Netflix needs an external stick
- Single-chip DLP with a phosphor wheel — some viewers see rainbow artifacts
- Contrast is a dynamic figure rather than a native one
Optoma UHZ35ST: what it gives up
- The lens is fixed: no zoom, no shift, so the screen size is set by where the projector sits
- HDMI 2.0, so 4K tops out at 60 Hz
- No smart platform at all
- At $1,849 it costs more than the brighter UHZ66 with a real zoom
- Optoma's standard warranty is one year in most markets, shorter than several rivals offer
