Optoma UHZ55

Name: Optoma UHZ55
Brand: Optoma
Price: 1599 USD
Availability: InStock

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. Optoma's lamp 4K models are brighter; the case for this one is that the laser takes lamp replacement out of the running cost.

What it does well

3,000 ANSI lumens from a 30,000-hour laser at $1,599 is the strongest brightness-per-dollar among the laser models here
+10% vertical lens shift plus a 1.3x zoom is modest but real placement flexibility
4 ms at 1080p/240 and 17 ms at 4K/60
20 W of built-in audio is enough for casual viewing without a soundbar
29 dB and only 10.6 lb

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

The two lists above are read off manufacturer specifications and published measurements, not from owner reports. Where owner discussion has been collected it appears separately below, so the two are never mistaken for each other.

Throw calculator

Worked from this projector’s published throw ratio of 1.21–1.59:1. Estimates: a real install loses a little to lens offset, and zoom ranges are quoted at the extremes of the lens.

The brightness figure is measured to a nine-point screen standard and is comparable with the rest of the catalog.

What owners say

This projector has the best-documented input-lag figures of anything in this catalog, because an owner published the measured numbers across every mode: 18 ms at 1080p/60 and 4K/60, 9 ms at 1080p/120 and 5 ms at 1080p/240 in enhanced gaming mode. The caveat that comes with them is important — those figures require game mode with no digital correction in the path, which means the projector has to be physically square to the screen.

The rainbow artifact produces the most interesting split in owner reports. One owner who sees it on many older DLP projectors says he almost has to force it on this one, crediting the higher refresh rate. Another has owned it four months, finds it hard to enjoy because of coloured flashes on end credits and bright objects in dark scenes, and is asking whether a grey screen would help. It would not: the artifact is in the light path, not the surface.

A few owners report HDMI inputs failing to synchronise with some sources, and the brand's one-year standard warranty makes owners more nervous about faults like that than they would otherwise be.

What owners like

Measured input lag is genuinely good across every mode: owners cite 18 ms at both 1080p/60 and 4K/60, 9 ms at 1080p/120 and 5 ms at 1080p/240 in enhanced gaming mode
At least one owner who sees the rainbow artifact on many older DLP projectors reports almost having to force it on this one, and credits the higher refresh rate
Owners recommend it as a strong second-hand buy while waiting for newer high-end models to arrive and push prices down
The 30,000-hour laser plus a 1.3x zoom and a little vertical lens shift give it more placement latitude than Optoma's lamp models

Common complaints

A few owners report HDMI inputs failing to synchronise with some sources
Another owner sees the rainbow artifact badly enough on this projector to struggle to enjoy it four months in, particularly on end credits and bright objects in dark scenes
Optoma's standard one-year warranty is called out as a hesitation, especially against brands offering three
Owners report that the low input-lag figures require game mode and no digital correction at all, which constrains where the projector can be placed

Questions owners ask about the Optoma UHZ55

What is the actual input lag?

Measured in enhanced gaming mode: 18 ms at 1080p/60, 9 ms at 1080p/120, 5 ms at 1080p/240 and 18 ms at 4K/60. Those require game mode with no digital correction — keystone in the signal path adds latency and negates the figures.

Will I see the rainbow effect on it?

Owner reports split sharply. One who is normally sensitive says he almost has to force it here. Another sees it badly enough after four months of ownership to find the projector hard to enjoy, especially on end credits. Sensitivity varies between people and no setting or screen removes it.

Would a grey screen reduce the rainbow effect?

No. The artifact is produced by the projector showing colours in sequence, not by the surface. A grey screen lowers reflected black and white by the same proportion and changes nothing about colour timing. The only fix is a three-chip projector.

Are there HDMI problems?

A few owners report inputs failing to synchronise with some sources. It is not universal — owners who have not seen it note they would expect it to have shown by now — but it is worth testing your specific source chain early.

How long is the warranty?

Optoma's standard coverage is one year in most markets, which owners raise as a hesitation against brands offering three. It varies by region, so check locally before buying.
