InFocus IN3138HD
1080p DLP Conference Room Projector

InFocus IN3138HD versus BenQ HT1075

Since the InFocus IN3138HD and the BenQ HT1075 are both 1080p projectors priced under $1000, a few comments on how they compare are warranted. But they are not at all built for the same purpose; the IN3138HD is intended to be an inexpensive conference room solution, and the HT1075 is an entry level home theater projector.

Seeing these two projectors side-by-side, their images look nothing alike. The IN3138HD prioritizes brightness, and its image has brilliant highlights and somewhat dull color. The BenQ HT1075 prioritizes contrast and color, so its image has deeper blacks and more accurate color that appears higher in brightness and saturation. Coincidentally, both projectors' Movie modes are about the same brightness; the IN3138HD measures 1,638 lumens while the HT1075 comes in at 1,782 lumens. However, most of the IN3138HD's lumens are only available for white light output due to BrilliantColor and the configuration of its color wheel. Speaking of color wheels, you will see rainbow artifacts much more often on the IN3138HD than you will on the HT1075, both due to the brightness of highlights and its slower color wheel.

So if the HT1075 has a better video image, why would anyone buy the IN3138HD -- even for business? For starters, it has connectivity that the HT1075 lacks, adding DisplayPort and multiple VGA connections as well as monitor passthrough and RJ45 networking. It is compatible with enterprise technologies like Crestron's RoomView system, and it can be monitored from a central location, thereby making life easier for your IT department. It has much higher light output for certain types of content, giving it an edge when you do need maximum brightness. Purchasing one of these projectors and then expecting it to do the job of the other is a good way to set yourself up for disappointment -- but then again, you shouldn't get frustrated with an apple because it's bad at being an orange.


The InFocus IN3138 is a solid choice for conference rooms. It is an inexpensive high-brightness projector that has great connectivity, full 3D capability, and network monitoring. If you need a conference room projector, it is definitely worth a look.

The IN3138HD includes certain features that make it ideal for conference room use, such as high white light output, excellent connectivity, wired networking, and compatibility with Crestron Roomview and AMX Device Discovery. If you're looking for a home video projector, other models exist that are built to do that job, and they do it well at the same price as the IN3138HD. The IN3138HD is built to be a solid conference room projector, and it performs that task quite well.
