Our take
The IN104 is a narrow fit for a room whose existing equipment still uses VGA or analog video. InFocus's model manual documents native XGA 1024 × 768 DLP, a 210 W UHP lamp, two VGA inputs, composite and S-video, component through a VGA connection, RS-232, and a 2 W speaker. The guide does not state ANSI brightness, HDMI, or the historic listing's 3D claim, so this should be chosen for documented legacy connectivity rather than assumed output.
A legacy school or meeting room with compatible VGA and analog video equipment.
Do not choose the IN104 for an HDMI-only source chain without a confirmed converter, modern Full HD detail, built-in streaming, or a room that requires known brightness and throw values. Its current lamp state and image output need inspection.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer reference guide confirms a native XGA DLP image for computer presentations.
- Two VGA inputs, component, composite, S-video, and RS-232 serve older classroom equipment.
- AC operation and a 2.4 kg body give it a straightforward fixed or carry-between-room role.
What to weigh up
- The exact manual does not list an ANSI brightness figure or verify the historic 2,700-lumen claim.
- No HDMI input or model-specific 3D feature is established by the reviewed manual.
- Throw ratio, remaining lamp life, and condition of a used unit are not known.

Full review: how the features affect your choice
What the features mean for you
XGA is useful for compatible older material
The InFocus reference guide names the IN104 and lists native 1024 × 768 XGA resolution. This matches many older 4:3 computer and classroom presentations, but it does not preserve the detail of a Full HD source. The model should be evaluated by the content it will show: menus, basic slides, and legacy documents may remain readable, while fine text or modern high-resolution video will be reduced. Higher input resolution is not evidence of a higher native panel.
Do not transfer the listing's brightness claim
The historic row advertises 2,700 lumens, but the checked InFocus model guide does not substantiate that number or give an ANSI rating for the IN104. The matching profile therefore leaves comparable brightness unresolved. That is important for buyers who need a known light level or want to rank it against projectors with explicit ANSI figures. The 210 W lamp is documented; its present hours and output depend on the specific unit and cannot be inferred from the model name.
The connection panel is the practical strength
The model guide lists two VGA computer inputs, a VGA monitor output, S-video, composite video, component input through the VGA connector, PC audio, and RS-232 serial control. That can simplify integration with an older classroom or conference system that already uses those cables. There is no HDMI documented in the checked manual, so a laptop with only a modern digital output needs a tested converter. The 2 W speaker is suitable only for modest audio needs.
Plan installation without an assumed throw ratio
The model-specific reference guide does not provide a verified throw ratio in the saved packet. Do not use another InFocus series' lens data to fill it. Before mounting, confirm the actual distance and screen size with a current exact-model calculator or measure the image from the unit. This is a legacy presentation device, not a documented ultra-short-throw model. Physical placement and focus should be tested before a permanent mount is installed.
Inspect the lamp and connectors
The IN104's UHP lamp and aging analog ports make unit condition central to the choice. Ask for the menu-reported lamp hours, inspect focus and color uniformity, and test both VGA sockets plus the intended video input. The checked manual supports the model identity and listed connectors, not the present condition of a secondhand projector. A buyer who needs 3D, an HDMI connection, or a specified brightness should request exact evidence for those needs instead of relying on the historic title.

Before you buy
Does the IN104 manual confirm 2,700 lumens?
No. The checked InFocus reference guide does not establish that historic listing claim or provide an ANSI brightness figure.
Does the IN104 have HDMI?
The model guide lists VGA, component, composite, S-video, audio, and RS-232, but does not document HDMI.
Is 3D confirmed for this model?
The historic listing says 3D-ready, but the exact InFocus IN104 guide checked here does not substantiate that feature.
