The HT4550i also has auto 2D vertical keystone adjustment and manual horizontal keystone adjustment, but because I measured things out correctly and adjusted the shift myself, there was little or no keystone adjustment needed (if it did it automatically, I didn’t notice). The HT4550i’s manual 1.3x zoom and manual focus allow for easy size adjustment, fine-tuned fitting, and focusing, which I actually prefer over automatic focus. I did notice that while shifting the image vertically to fit my screen, the image skews slightly up and to the right, requiring you to adjust the projector’s position to compensate. The BenQ HT 4550i has a 0% to -60% vertical lens shift and a +/- 15% horizontal lens shift, which means that you have some leverage for moving your image left, right, and up and down to perfectly align it to the screen using the manual shift dials on top of the unit. I projected a 100-inch image on a 16:9 screen and placed the HT45501 about 9.5 feet away. On the maximum end, it recommends a 200-inch image at a distance of around 16 feet. For example, while the chart has measurements for an image size as small as 30 inches, BenQ recommends a minimum 60-inch image, with the projector at a minimum distance of around 5 feet. The included quick-start guide includes a helpful distance-to-screen chart for figuring out where it should be placed in a wide range of room sizes. And while things like placement distance and height, as well as keystone and focus adjustments, need to be taken into consideration with any projector, going from unboxing to showtime with the HT4550i is pretty straightforward. Setting up a projector - especially one in this price range that’s meant for more dedicated home theater setups - can be intimidating.
