Our take
The IN5108 is a large-room installation projector for users who need a high-output 4:3 image, native SXGA+ detail, and lens choices that can match a difficult throw distance. InFocus's manufacturer sheet specifies 4000 max ANSI lumens, a 1400 × 1050 panel, horizontal and vertical lens shift, and four optional optics. These are concrete fit advantages for an existing meeting or auditorium system. Its 4:3 default and discontinued lamp design make it a specialist choice; buyers should check the exact lens, lamp, and connections before planning around a used unit.
Fixed meeting, auditorium, or venue installation where a 4:3 source and flexible optics are useful.
It is not for a battery-powered setup, native widescreen Full HD or 4K priority, ultra-short-throw wall placement, or an all-in-one streaming experience.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- InFocus specifies native 1400 × 1050 SXGA+ resolution and 4000 max ANSI lumens.
- Horizontal and vertical lens shift can ease alignment in a fixed installation.
- Four optional lenses span short, standard, long, and ultra-long projection ranges.
What to weigh up
- The model defaults to a 4:3 image, which is not the natural format for modern widescreen video.
- Optional lenses are separate components whose fit and availability must be confirmed.
- The UHB lamp is an aging service item; current hours and brightness are unit-specific.

What the features mean for you
A fixed venue role with room for integration
InFocus's product sheet presents the IN5100 family for large venues, installation, and integration, and the user guide describes a commercial operating environment. The IN5108 is therefore more relevant to a meeting room, auditorium, or fixed presentation system than to a projector carried between homes. Its 15.7-pound body, AC connection, and multiple control inputs suit a planned installation. A buyer should account for ceiling support, cable routes, cooling clearance, and the service access needed for a lamp. If the main need is occasional family movie viewing, a home-theater model will be simpler to place and source.
SXGA+ gives a different balance from Full HD
InFocus specifies 1400 × 1050 native SXGA+ resolution, with a 4:3 default aspect ratio. That produces more vertical pixels than XGA and can help detailed data slides or technical diagrams while preserving a traditional presentation shape. It has fewer horizontal pixels than a 1920 × 1080 Full HD model, so widescreen video will not use the panel in the same way. Supported signal modes are inputs, not a promise of extra native detail. Match the panel to the source material and audience position rather than choosing from resolution labels alone.
Read the ANSI rating with the lamp in mind
InFocus's manufacturer specification sheet gives the IN5108 a maximum rating of 4000 ANSI lumens, with a lower Eco-mode figure also listed. The ANSI basis is useful when comparing it with other models whose sources make the same label explicit. The original rating describes a new lamp under specified settings, not the condition of a lamp that has been used for years. Before relying on the number, request the lamp counter, check the lamp model, and inspect a representative image at the intended screen size and ambient light. A large room still needs an appropriate screen and measured setup.
Choose the lens after measuring the room
The standard IN5108 lens has a 1.5:1–1.8:1 throw range, while the InFocus sheet lists four optional lenses from a fixed 0.8:1 option through a 3.9:1–7.4:1 ultra-long optic. The manufacturer also documents horizontal and vertical lens shift. This combination can help when the projector must sit at a particular mount point or throw across a long hall. It does not mean every lens is included in the historical package. Identify the exact lens installed, calculate the needed image width and distance, and confirm the lens part number before purchase.
The ports suit a wired professional system
InFocus lists HDMI 1.3, 5BNC, VGA, component, composite, S-video, network control, RS-232, USB presentation control, and assignable audio inputs. This can connect a mix of older and newer sources in a fixed venue, but adapters may be needed for current laptops and players. The optional LiteShow II adapter is a separate wireless presentation accessory, not proof of integrated streaming apps. The user guide and product sheet do not document an app platform. Plan an external source and inspect the exact port panel so a legacy connector does not become a surprise during installation.
Inspect the unit and compare formats before buying
The IN5108 was introduced as an older model and InFocus no longer offers it as a current product. That makes the model-level specification only one part of a purchase decision. Check the exact model label, installed lens, lamp hours, lamp and filter availability, focus across the image, dust, image alignment, remote, and every input your system uses. Compare the BenQ SH940 if native 16:9 Full HD and two-axis lens shift matter more than interchangeable optics. Compare the Hitachi CP-X1250W for higher ANSI output and motorized vertical shift, accepting a lower XGA image format.
What else to compare
The BenQ SH940 has a native 16:9 Full HD panel and 4000 ANSI lumens with horizontal/vertical shift. The Hitachi CP-X1250W trades SXGA+ detail for 4500 ANSI lumens and motorized vertical shift. Both are older fixed-installation lamp models.
Before you buy
What is the IN5108 native resolution?
InFocus lists native SXGA+ at 1400 × 1050 pixels, with 4:3 as the default aspect ratio.
Is its 4000-lumen figure ANSI-rated?
Yes. The InFocus IN5100 manufacturer sheet labels the IN5108 maximum rating as 4000 ANSI lumens.
Does the standard lens fit every room?
No. The standard throw is 1.5:1–1.8:1; four optional lenses cover other distances and must be checked separately.

The decision
Shortlist the IN5108 when a fixed venue needs 4:3 SXGA+ detail, a stated ANSI rating, and a lens matched to the room. Verify the installed optics and lamp before relying on it.
