The Acer H7550ST 3000-Lumen Full HD Short Throw DLP Projector features a short 0.69 to 0.76:1 throw ratio, so you can operate it in settings where the projector needs to be as close as 35.4" to the screen, such as in a narrow room. With a brightness of 3000 lumens, the projector can overcome a moderate amount of ambient light while maintaining decent contrast and color reproduction. It has a 16:9 native aspect ratio and 1920 x 1080 native resolution. Its lamp will last approximately 4000 hours in Normal mode, and up to 8000 hours in ExtremeEco mode.
To accommodate a variety of video sources, including DVD and Blu-ray players, computers, document cameras, media players, and more, the projector features an assortment of digital, analog, and audio inputs. These include HDMI, S-video, component, and composite. There is also a built-in 10-watt stereo speaker in case a separate sound system is unavailable.
3000 Lumen Lamp
A single lamp provides 3000 lumens of brightness in Normal mode and is estimated to last 4000 hours.
0.69 to 0.76:1 Throw Ratio
Throw ratio tells you the image size you will get at a given distance from the screen. At the variable 0.69 to 0.76:1 throw ratio, you can achieve a 54" image with the projector only 35.4" from the screen.
16:9 Native Aspect Ratio
This projector features a 16:9 native aspect ratio. The projector can display images and video in 4:3 also, though black bars (pillaring) will have to be applied, or the image will have to be stretched or cropped to fit.
HDMI with MHL Support
Two of this projector's HDMI ports feature MHL (Mobile High Definition Link) compatibility. In addition to the normal video pass-through capability of HDMI, MHL means the projector can power select devices, such as many Android smartphones, through the same connection. An MHL-to-HDMI cable is required, available separately.
