Our take
The IN3104 is a conventional lamp projector for meetings where a native 4:3 XGA image and a source-labeled ANSI rating matter more than widescreen detail. Its IN3100-series sheet documents 3500 maximum ANSI lumens, an HDMI input, VGA, composite video and computer-over-USB DisplayLink. Choose it for a compatible presentation room after checking the lamp, ports and throw distance on the exact unit.
A wired presentation room that values a documented ANSI rating and can use XGA detail..
It is not a native Full HD or 4K home-cinema choice, a battery projector, or a close-wall ultra-short-throw model.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The model-specific sheet names IN3104 and lists its 3500-lumen maximum as ANSI.
- Native XGA and a 4:3 default image suit traditional slides and documents.
- HDMI, VGA, composite, RS-232 and DisplayLink give several documented wired routes.
What to weigh up
- Native 1024 × 768 gives less room for fine spreadsheets and detailed widescreen images.
- The 3500 ANSI figure is a model rating, not a measurement of a used lamp.
- The 5–36 ft projection range still requires a planned projector-to-screen distance.

What the features mean for you
Is XGA enough for the slides you use?
InFocus lists the IN3104 as native XGA at 1024 × 768, with a 4:3 default aspect ratio. That format remains workable for conventional slide decks, basic charts and older computer sources, but small spreadsheet text has fewer pixels than on WXGA or Full HD. A laptop may send a higher resolution, yet the projector scales it to its own panel. Match the model to the source material and how far viewers sit from the screen. For fine engineering drawings, dense tables or widescreen movies, choose a higher native resolution instead of relying on an accepted input format.
How should the 3500 ANSI rating affect a meeting-room choice?
The InFocus series sheet explicitly assigns up to 3500 ANSI lumens to IN3104 and IN3108, while listing lower figures for the other models in the series. That makes the rating useful for model-level comparison, but it does not establish present output from an individual projector. Lamp hours, picture mode, room light, screen size and maintenance all matter. Ask for the exact model label and lamp-hour display, then view a projected slide at the intended size. The rating is a stronger comparison point than a generic lumen claim, not a promise about an old unit.
Can its lens fit the available room?
The product sheet gives a projection range of roughly 5 to 36 feet and describes a conventional front projector. That range is broad enough for different meeting rooms, but it is not an ultra-short-throw design. Measure the screen width and distance from the lens to the screen before choosing a shelf or ceiling mount. The manual lens controls can help focus and size the image within their range; they do not replace a room-distance calculation or create optical lens shift. For a wall-mounted interactive board with little clearance, compare a true UST model instead.
What source connections are documented?
InFocus lists HDMI, VGA, RS-232 and composite video for the IN3100 series, plus a mini-USB DisplayLink path that can carry computer audio and video. The sheet also describes an optional LiteShow II wireless adapter. The adapter is optional equipment, so its presence on any current offer is unknown. USB DisplayLink is a presentation connection, not evidence of installed movie apps. Confirm which inputs work and whether your computer supports the required DisplayLink software before planning a room around cable-free presentations.
What does the lamp mean for long-term ownership?
This is a lamp-based business projector rather than a laser model. The series sheet describes lamp modes and rated life, but those figures describe a new lamp under the stated mode; they do not report remaining life in a used unit. Inspect the lamp timer, filter, fan, image uniformity, focus and all input ports. A buyer replacing a meeting-room projector should also confirm that the old VGA or composite source is still in the room, because an HDMI-first replacement may be simpler if those connections are no longer needed. Check service parts independently before assuming a legacy model is inexpensive to keep.
Who should keep the IN3104 on the shortlist?
Keep it in consideration when the source is a computer or media device with compatible outputs, the room can accept XGA, and the manufacturer-rated ANSI figure is useful for screening candidates. It is a narrower fit for dense text, current 4K home video or a portable presentation routine. Compare its room geometry with any replacement before buying, then verify the actual remote, power cord, lamp hours and image. The historic candidate ASIN is not a current offer identity; use the exact-model tagged search and compare the specific unit that is available.
What else to compare
Compare a WXGA presentation model for wider slides or a documented interactive UST projector when the unit must sit near a classroom board.
Before you buy
What is the IN3104's native resolution?
InFocus lists native XGA 1024 × 768 for the IN3104; higher accepted input formats are scaled.
Is the brightness rating ANSI-labeled?
Yes. The InFocus sheet lists up to 3500 ANSI lumens for IN3104, but a used lamp may produce less.
Does it support wireless presentations out of the box?
The sheet describes an optional LiteShow II adapter; verify whether any current offer includes it.
Is it suitable for an ultra-short-throw board setup?
No UST lens is documented; InFocus gives a conventional projection range of about 5 to 36 feet.

The decision
Choose IN3104 for a wired XGA meeting room that can use its 3500 ANSI model rating; inspect the lamp and measure the throw before purchase.
