InFocus IN3138HD
1080p DLP Conference Room Projector

Bill Livolsi, October 8, 2014


Light output. Though the IN3138HD claims 4,000 lumens maximum output, the best we could get was just over 3,000 in a usable image mode. Lumen output measured higher if we cranked brightness and contrast to their highest levels, but doing so had a serious detrimental effect on image quality and is not something we recommend. Even at those extreme settings, we were unable to hit 4,000 lumens. And in the projector's more color-balanced modes, light output hovers right around 1,600 lumens.

Native 1080p. In business environments, the preferred widescreen resolutions are 1280x800 or 1920x1200. The former matches up with many laptop computers, while the latter maintains the same 16:10 aspect ratio but can also natively display 1080p HD video. But 1080p itself is 16:9, so content created for native 16:10 displays can only be displayed with black pillars to either side of the image. If the majority of your content is 16:10, that's worth considering before making a purchase.

Color light output. The IN3138HD measured 3,014 ANSI lumens maximum. However, ANSI lumens only measure a projector's brightness on a pure white test image, and most of the content you'll be using is not pure white. Color light output can be a useful indicator of how a projector will look when using content like photographs or video, where color and image balance are more important. Color light output is obtained by measuring the brightness of red, green, and blue, adding them together, and comparing the result against the readings taken from a white test pattern.

On the IN3138HD, sRGB mode is the only preset image mode where color brightness measured 100% of white. The next best modes, Movie and Game, both measured 55%. TV mode measured 52%, Presentation mode came in at 43%, and Bright mode measured only 28%.

If you do need to display photographs or video, sRGB mode is a safe bet -- but it measured only 782 lumens. You can also use Movie or Game mode and decrease BrilliantColor if image balance is not to your liking (though this will both decrease white light output and kick you over to User mode).

Fan noise. The IN3138HD is bright and small, so it's not surprising that it has a loud exhaust fan. In a small room, fan noise is loud enough to be noticeable even when the lamp is set to low power, and the high lamp setting will heat up the whole room given enough time. This won't be a problem for short presentations and rooms with adequate ventilation, but the fan noise is still quite present.

Locked presets. The IN3138HD's image modes cannot be adjusted. The settings they come with from the factory are the settings they keep, and changing any setting will boot you over to the single User memory. You can adjust absolutely anything in the User setting, but you only get one. If you need to store two sets of settings, you'll have to write one of them down.
