Our take
The InFocus IN3146 is a professional WXGA projector with native 1280 × 800 resolution, lamp illumination, manual zoom/focus, HDMI and LAN connections, and a 5500-lumen figure in an InFocus-authored specification. That number is not explicitly labeled ANSI in the saved source, so the profile leaves ANSI lumens unknown. The model is most appropriate for a permanent business or training-room role where an external computer or network source is expected. Its size, AC power, and lamp make it very different from a battery portable. The historical candidate's current offer, lamp hours, and exact package are not verified.
A fixed office or training room with a source-connected workflow and a substantial AC-powered projector.
It is not for a carry-anywhere battery setup, integrated streaming apps, a confirmed ANSI-output threshold, or a high-detail Full HD/4K home cinema.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- InFocus documentation identifies native WXGA 1280 × 800 for a widescreen presentation format.
- The model datasheet lists HDMI, LAN, 3D, and a 10 W mono speaker for professional installations.
- Manual zoom and focus give installers documented controls for setting up a conventional image.
What to weigh up
- The 5500-lumen figure is not labeled ANSI in the saved InFocus source.
- A replaceable lamp makes hours and remaining life specific to the used unit.
- The model's larger professional-room role is a poor fit for battery portability or app-based viewing.

What the features mean for you
A professional room is the natural use case
InFocus places the IN3146 in its network-projector series, and the model documentation includes HDMI and LAN alongside presentation and 3D functions. That points toward a fixed office, training room, or institutional setup that already expects an external source. It is not a lightweight pocket product, and no internal battery is documented. Buyers should consider the device's size, mounting location, ventilation, and AC route before choosing it. The recommendation is based on the model's stated role and ports; it does not claim a current installation or a tested experience with a particular unit.
WXGA provides widescreen presentation space
The exact IN3146 datasheet identifies native WXGA 1280 × 800. This format is useful for many modern slides and computer desktops because it is wider than the 4:3 XGA and SVGA images common in older projectors. It is still below Full HD, so home-theater buyers who prioritize fine detail should compare native 1920 × 1080 or higher alternatives. An input signal does not change the native imaging resolution. Check slide text at the intended screen width and seating distance. For a professional presentation room, WXGA may be a practical balance; for cinematic viewing, it may be a compromise worth avoiding.
Do not relabel the brightness figure
The InFocus-authored sheet gives a 5500-lumen output figure but does not label it ANSI. We preserve that distinction and keep the ANSI attribute null. This prevents an unsupported apples-to-apples comparison with Optoma's explicitly ANSI-rated EH460ST. Output depends on mode and lamp condition, and a used unit's actual image may not resemble the original model specification. Ask for lamp hours, a demonstration at the intended image size, and information about any replacement lamp. Ambient light and screen surface also matter. This review makes no measurement claim and does not infer an ANSI standard from a high numeric value alone.
Manual optics and AC power shape placement
InFocus materials document manual zoom and focus, as well as a conventional projector setup. Measure the distance from lens to screen, desired width, and mounting height before purchase. The saved sources do not establish UST placement or optical lens shift. That means the room should provide a plausible throw position rather than expecting flexible image movement after installation. This is an AC-powered lamp projector, so plan electrical access and service clearance. A ceiling mount or shelf should be selected after checking the model manual's dimensions and clearances. Do not assume keystone correction can replace a suitable throw and square placement.
Inspect the lamp and connection path
The model uses a lamp and offers HDMI and LAN inputs, with manual control of zoom and focus. Check the startup sequence, lamp-hour menu, focus across the frame, uniformity, fan sound, image color, port function, remote, power cable, and any mounting or network accessories. The specification does not establish an integrated streaming-app platform, so add a suitable external player if online video is part of the plan. The candidate title's word Professional does not guarantee a complete installation kit. Confirm the IN3146 nameplate and exact offer contents; the tagged search is a discovery link, not proof of stock. These are evaluation steps rather than firsthand testing results.
What else to compare
For a native Full HD business projector with an explicit 4200 ANSI rating and short-throw lens, compare Optoma EH460ST. For a smaller meeting-room projector, compare Epson PowerLite 755C, whose 2000 ANSI rating and 3.9 lb body are documented.
Before you buy
What is native resolution on IN3146?
InFocus specifies native WXGA 1280 × 800 resolution for the IN3146.
Does InFocus publish 5500 ANSI lumens?
The saved InFocus-authored material says 5500 lumens without an ANSI label, so this profile does not treat it as ANSI.
Does it include streaming apps?
The sources document HDMI/LAN and local inputs, not an integrated streaming-app operating system; plan an external source.

The decision
IN3146 suits a professional presentation room when its WXGA image, installation footprint, and lamp maintenance fit. Keep 5500 lumens separate from ANSI and inspect the actual unit.
