Our take
Acer P1173 is a legacy SVGA projector whose original Acer family manual identifies native 800 × 600 resolution, 1.1× manual zoom and focus, conventional 1.86–2.04:1 throw, and AC lamp operation. The candidate title mentions 3000 lumens, but the saved primary Acer manual does not establish that number as an ANSI rating, so brightness stays unknown in the comparison profile. Its most defensible role is a basic source-connected presentation setup where SVGA is sufficient and the lamp can be checked. The historical row's exact condition, accessory package, and current seller offer remain unresolved.
Basic presentation use with legacy material, a measured conventional throw, and a verified lamp.
It is not for native Full HD or 4K, fine text at large screen sizes, battery projection, streaming apps, or buyers who require a verified ANSI output number.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The Acer family manual identifies native SVGA 800 × 600 and model-specific setup guidance.
- A 1.86–2.04:1 throw range and 1.1× manual zoom support a concrete placement check.
- The AC lamp profile makes power and maintenance requirements clear.
What to weigh up
- SVGA is a low-detail 4:3 image for current widescreen video and small labels.
- The historical 3000-lumen title wording is not verified as an ANSI rating by the saved Acer source.
- Lamp hours, current condition, and the exact old listing package are unknown.

What the features mean for you
A legacy model needs a legacy use case
The P1173 belongs in a presentation comparison only when the source material and screen size do not demand much detail. Acer's original family manual identifies it as native SVGA 800 × 600. That 4:3 format can still display uncomplicated slides or support an older equipment room, but it is far below Full HD. Modern wide charts, fine spreadsheet text, subtitles, and detailed video expose the limitations quickly. A connected laptop may send a different signal, but the projector does not become higher resolution. Decide what will actually be shown before treating a low-cost legacy unit as a substitute for a modern meeting-room model.
Do not convert a title lumen claim to ANSI
The historical listing title states 3000 lm, but the Acer primary manual reviewed here does not provide a standardized ANSI value for P1173. That leaves ANSI brightness unknown. Projector titles often combine model names and generic output claims, and those numbers should not be transferred without a clear model source and measurement basis. For a used lamp unit, ask for its lamp hours and see the image at the expected screen size if light output matters. Room lighting, mode, wear, and screen material all affect readability. No current brightness measurement or tested result is claimed for this model.
The manual gives a useful throw window
Acer's family guide identifies a 1.86–2.04:1 throw range and 1.1× manual zoom and focus for the P1173. Those specifications let a buyer compare the lens-to-screen distance with the intended image width. The zoom provides only a modest adjustment, so measuring before choosing a table or mount is important. It is a conventional placement model, not UST, and the saved source does not establish optical lens shift. Plan the projector's height, angle, power cable, and source lead before installation. A general claim that a unit is portable does not remove the need to check the throw geometry.
Use an external source and maintain the lamp
The Acer manual describes conventional source connections and lamp operation, not a built-in streaming service. A laptop or external media device is needed for modern online video. The projector uses AC power, so it is not a battery model. On older hardware, inspect the lamp, fan, vents, focus, image uniformity, input sockets, remote, and power lead. Ask which adapters and cables are included; the historical row does not settle that question. A seller demonstration is useful for condition assessment, but this review does not claim a hands-on test. Keep the exact Acer code in view so the P1173 is not confused with adjacent P1-series models.
Let uncertainty shape the recommendation
Acer documentation provides a dependable resolution and placement outline but does not verify every claim in the candidate title. In particular, ANSI output remains null rather than being guessed from a generic lumen statement. The candidate's current offer and hardware condition are also not verified. That makes the P1173 more appropriate for a buyer who can identify the exact device, assess an old lamp, and accept a modest image. If output is a hard requirement, compare with models whose exact source labels ANSI lumens. If resolution matters, choose a WXGA or Full HD alternative. This source-based profile intentionally avoids claims about performance on a specific used unit.
What else to compare
For an explicit 2000 ANSI rating with native XGA, compare Acer PD100, although it remains a low-resolution lamp model. For widescreen WXGA presentations, compare InFocus IN2126a while keeping its lumen method unqualified.
Before you buy
What is the P1173 native resolution?
Acer's P1-series user guide identifies native SVGA 800 × 600 resolution.
Is its 3000-lumen title claim an ANSI rating?
The saved Acer source does not establish an ANSI figure for P1173, so the matching profile leaves ANSI lumens unknown.
What throw range should I plan around?
The Acer family manual lists a conventional 1.86–2.04:1 ratio and 1.1× manual zoom; measure your image width and lens distance.

The decision
P1173 can fit a simple legacy presentation room when its SVGA image is acceptable. Keep the brightness claim unknown and inspect the actual lamp and inputs.
