Our take
The InFocus IN112a is a wired presentation projector whose main advantage is a wide selection of inputs, including HDMI, two VGA ports, composite, and S-Video. Its native 800 × 600 SVGA image is substantially less detailed than current HD displays, which makes it a poor fit for fine text or cinematic viewing. The datasheet lists 3,000 lumens but does not identify the figure as ANSI. Lamp mode and condition should be checked carefully because the unit uses a 190 W projection lamp.
Choose it only for a wired presentation role where exact inputs, modest image detail, and lamp condition suit the room..
Do not choose it for native HD or 4K detail, built-in apps, battery use, a strict verified ANSI-lumen threshold, or modern home cinema.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HDMI is available beside two VGA inputs and several legacy video connections.
- The manufacturer lists a low-power mode and Eco Blanking lamp-life claim.
- A 2 W speaker provides basic integrated audio for small presentation use.
What to weigh up
- Native 800 × 600 resolution is limiting for detailed slides and video.
- The listed 3,000-lumen output is not labeled ANSI in the datasheet.
- A 190 W lamp makes age, hours, and replacement status important.

Full review: how the features affect your choice
What the features mean for you
SVGA resolution favors older presentation sources
The InFocus-authored IN110a Series datasheet lists native 800 × 600 resolution for the IN112a. This is SVGA, a 4:3 format that can still suit older presentation material and basic diagrams, but it has far fewer pixels than an HD projector. Small spreadsheet text, browser interfaces, and detailed video can look constrained. A source may send a higher-resolution signal, yet the projected image still uses the native grid. Confirm that the intended material remains readable at the actual screen size before considering this model for a room.
Output claims do not establish ANSI brightness
The datasheet gives a 3,000-lumen figure in normal mode and 2,800 in low-power mode, without an ANSI label. Its 15,000:1 contrast figure is also a manufacturer specification rather than a guarantee of perceived contrast in a particular room. Keep the measurement wording intact when comparing this model with projectors whose brightness is explicitly expressed in ANSI lumens. Screen size, room illumination, and lamp condition affect real use. For a used projector, examine its current image and operating hours instead of assuming its original rating remains unchanged.
The input panel is useful for mixed equipment
InFocus lists HDMI 1.4, two VGA inputs, composite video, S-Video, USB-B, RS-232, and a VGA monitor output. That mix is useful in a room that still connects older computers or video equipment while retaining an HDMI route for newer devices. It does not make the IN112a a network streamer: the USB-B connection is not the same as USB media playback, and no app platform is documented. Check the exact cable and output needs of every source before purchase, especially if a modern computer uses an adapter.
Lamp modes affect maintenance expectations
The projector uses a 190 W lamp, with datasheet estimates of up to 5,000 hours in normal mode, 6,000 in low-power mode, and 10,000 in Eco Blanking mode. These are operating-mode ratings, not a reading of the installed lamp. Ask for the unit's lamp counter and replacement history, and verify the exact lamp part before committing to a used example. InFocus also states that no filter replacement is required. That reduces one scheduled task, but dust, ventilation, lamp condition, and fan noise still deserve inspection.
Keep its role narrow and practical
The datasheet calls the IN112a a presentation projector and specifies a 2 W mono speaker. Its strongest use is a meeting or classroom with compatible wired sources and content that remains legible at SVGA resolution. The compact speaker is a convenience for basic narration, not a substitute for larger-room sound. There is no documented battery or streaming platform. If the projector will be mounted, confirm the throw distance and image size from the model-specific manual; do not assume a short-throw placement from a different IN110a family member.

Before you buy
Is the IN112a native 1080p?
No. The InFocus datasheet specifies native SVGA resolution of 800 × 600 pixels.
Is 3,000 lumens an ANSI rating?
The datasheet lists 3,000 lumens but does not label that figure as ANSI, so the ANSI profile remains unknown.
Can it connect to an HDMI source?
Yes. The manufacturer datasheet lists HDMI 1.4 along with VGA and legacy video inputs.
