Our take
The InFocus IN3136a is a high-output presentation model with native WXGA 1280 × 800, 4,500 ANSI lumens, a 1.45–2.17:1 conventional throw, and 1.5× manual zoom. InFocus also documents LAN control and lamp illumination. Those facts point to an installed room with a known screen position, power, and wired sources. High rated output does not guarantee a clean image from an older projector; lamp hours and service condition matter. It is not a battery or smart-app model, and it needs meaningful throw distance.
A fixed meeting or classroom installation needing high rated output and LAN management.
It is not for a shallow UST cabinet, battery travel, integrated streaming apps, or a high-resolution home cinema requirement.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- InFocus specifies 4,500 ANSI lumens and native WXGA for the IN3136a.
- A 1.5× zoom offers more installation adjustment than a fixed lens.
- LAN control suits managed classroom or conference-room equipment.
What to weigh up
- The lamp's actual remaining life depends on the specific projector.
- The 1.45–2.17:1 ratio requires substantial conventional throw distance.
- Network management does not establish streaming apps or wireless media playback.

What the features mean for you
WXGA is designed for widescreen presentation work
The IN3136a's native panel is 1280 × 800 WXGA. This 16:10 format is practical for computer presentations and many classroom layouts. It is not Full HD, so a buyer focused on detailed movies or fine 1080p images should compare higher-resolution alternatives. The stated native resolution describes the projector's display panel; input formats may be accepted and scaled. Match content, screen shape, and audience distance to the actual format. In a business room where slides dominate, native WXGA can be adequate without claiming cinema-level detail.
The ANSI number is useful, but unit condition still matters
InFocus lists 4,500 ANSI lumens, a clearly labeled output basis that distinguishes this model from projectors with unqualified lumen claims. The figure supports a presentation role where there may be some room light, but screen size, image mode, and room conditions remain important. A lamp projector's current output depends on lamp hours, replacement parts, dust, and maintenance. Request the usage counter and inspect brightness across the whole image. Do not assume the original rating applies unchanged to a used or refurbished unit.
Zoom helps placement within a conventional room
The 1.45–2.17:1 throw range and 1.5× manual zoom allow the image to fit a range of conventional room distances. Measure lens-to-screen distance and image width before selecting a ceiling mount; a longer room may require a different screen size than expected. The ratio is not UST, and no optical lens shift is established in this packet. Avoid depending on digital correction as a substitute for careful mounting. The zoom ring can help finalize placement, but the projector still needs a clear, stable, well-ventilated position.
LAN control is for management, not app streaming
The series sheet documents network management along with wired presentation inputs. That can be useful to an administrator controlling equipment in a meeting room, yet LAN control is not the same feature as a built-in streaming platform. Use an external computer or media player for content and verify its input connection. The projector is lamp-based and intended for AC operation; it has no documented internal battery. Keep these distinctions clear when comparing it with portable smart projectors. Confirm the exact ports and network configuration on the specific used unit.
Inspect the installation equipment as a system
The IN3136a suits a fixed office or classroom where high labeled brightness, zoom flexibility, and remote management are useful. It does not suit a shallow room without distance or a traveler who needs battery operation. Inspect lamp hours, lens, fan, LAN and video ports, remote, mounting hardware, and image geometry on the offered unit. The tagged exact-model search does not assert a current seller or package. Compare it with another presentation projector only after recording screen width, throw distance, lighting, and source requirements for the room.
What else to compare
For a shorter-throw presentation setup, compare InFocus IN26+. For a classroom UST solution with optional interaction, compare BenQ MW820ST.
Before you buy
Is the IN3136a rated at 4,500 ANSI lumens?
Yes. InFocus's series sheet labels the output as 4,500 ANSI lumens.
Is its lens ultra-short throw?
No. The 1.45–2.17:1 ratio is conventional throw and requires room distance.
Does LAN control mean it can stream apps?
No. LAN management is documented, but an integrated streaming-app platform is not.
