Our take
The Play Big IN72 is a legacy home projector with a verified 854 × 480 panel, an exact placement table, and a model-specific image offset. It may suit a low-detail legacy source when the room fits, but its resolution is far below Full HD and ANSI output remains unresolved.
A legacy home-cinema setup where the buyer can measure the screen distance and verify the exact unit's image quality.
It is not a dependable recommendation when buyers need Full HD detail, a verified ANSI threshold, built-in apps, or verified compatibility with a current source. Inspect and test the exact older unit before planning around it.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- InFocus provides an IN72-specific distance range for four screen sizes.
- The guide identifies a 128% offset for IN72, distinct from the IN74/IN76/IN78 value.
- The exact Play Big model is listed in InFocus's projector support materials.
What to weigh up
- The native 854 × 480 image carries much less detail than Full HD projectors.
- No IN72-specific ANSI brightness value is supported in the saved sources.
- Lamp condition, exact inputs, remote, and current service availability require unit-level confirmation.

What the features mean for you
What does the IN72 placement chart tell you?
InFocus gives a model-specific lens-to-screen range for the IN72: 60 inches at 2.4 to 2.8 metres, 80 inches at 3.2 to 3.8 metres, 92 inches at 3.7 to 4.3 metres, and 150 inches at 5.9 to 7.0 metres. These values let a buyer compare a room with a planned screen instead of guessing from another projector in the series. The table also advises keeping the projector at least 1.5 metres from the screen and allowing space around the body. Measure from the lens, not the back of a cabinet, and account for the zoom setting. The chart describes model geometry only; it does not confirm the focus or lens condition of a particular used projector.
Why does the 128% image offset matter?
The guide identifies 128% image offset for the IN72 and separately gives 115% for IN74, IN76, and IN78. That difference changes where the picture lands relative to the lens and can affect a shelf, ceiling mount, or screen height. Do not use the adjacent models' placement diagram when installing an IN72. Leave room to adjust height and verify whether the projector will be upright or ceiling-mounted. Keystone correction may alter the image shape, but it is not a replacement for matching the model's offset to the screen. If a seller cannot show the exact model label, pause before drilling a mount or promising a fixed installation.
What does native WVGA resolution mean for viewing?
The InFocus guide explicitly lists native 854 × 480 resolution for IN72, a WVGA image with much less detail than Full HD. That can be adequate for an older video source or a simple large image, but small subtitles, interface text, and detailed graphics will not have the definition of a 1920 × 1080 panel. The guide separately gives higher resolutions for IN74, IN76, and IN78; those values must not be transferred to IN72. The native pixel count makes the tradeoff clear before installation and excludes the model from hard Full HD requirements. Check the exact screen size and content because scaling an HD input cannot add detail that the panel does not contain.
Why is ANSI brightness also unknown?
The checked InFocus materials do not give an IN72-specific ANSI-lumen figure. Brightness values from neighboring IN70 models cannot be carried over, and no historical candidate title is used as proof. As a result, the IN72 should not pass a hard ANSI requirement or be ranked as brighter than a model with a verified value. For a used example, ask for a working image, inspect evenness and color, and check lamp hours if that information is available. The manual's placement recommendations do not estimate how bright the picture will appear. Screen size, ambient light, lamp age, and the chosen mode can all change the practical result, while the published evidence here leaves the model rating open.
Who should take a chance on this older projector?
The IN72 is a reasonable candidate only for someone who already understands the limits of an 854 × 480 legacy home projector, can fit the documented distance and offset, and can verify the exact unit before paying. A modern Full HD model is the safer choice when resolution and a comparable brightness rating are decision requirements. A short-throw model is better when the room cannot provide the IN72's minimum spacing. Check every input you plan to use, the remote, lamp warning, focus across the screen, image uniformity, fan, and mounting hardware on the unit. This review leaves the ANSI rating unknown; it is based on the InFocus guide and support listing, not hands-on testing.
What else to compare
Choose an exact-model projector with documented native resolution and ANSI output when image detail and brightness must be compared before purchase, or a short-throw design when room distance is limited.
Before you buy
Does the IN72 manual establish native Full HD resolution?
No. InFocus specifies native 854 × 480 WVGA for IN72; the higher-resolution sibling models are different projectors.
How far away should the IN72 sit for a 60-inch image?
InFocus gives a 2.4 to 2.8 metre range for a 60-inch image in its IN72-specific placement table.
Is its 128% offset the same as other IN70 models?
No. The guide specifies 128% for IN72 and 115% for IN74, IN76, and IN78, so use the exact model chart.

The decision
The IN72's useful evidence is its native WVGA panel, exact placement chart, and model-specific 128% offset. Keep ANSI output unknown, then verify the label, image, inputs, and condition of any used unit.
