The HW45ES throws a 120" 16:9 image from a range of just under 12 feet to not quite 19 feet. The Projection Calculator will let you determine the range for the screen size you want.
With the projector sitting on a table and the image at the middle position of its vertical shift, the centerline of the lens is at the geometric center of the image. The measured vertical shift is 80% of the image height up or down from that center position, which is a little more than the plus or minus 71% that Sony claims. The horizontal shift varies from 0% of the image width to plus or minus 26%, depending on where the lens is in its vertical range.
At 20 pounds and 7.1" by 16.1" by 18.4" (HWD), the HW45ES is obviously meant for permanent installation. The 1.6x zoom and the vertical and horizontal lens shift make it equally appropriate for a ceiling mount, a table, or a large rear shelf on a back wall behind the seating area. The front-facing exhaust vents, on both the front of the projector and near the front of each side, help make it particularly appropriate for a rear shelf. The intake vents are on the rear. Sony recommends leaving a 2-inch gap on all sides. However the rear panel curves in a tight arc, so even if you accidentally have the rear panel touching the wall, most of the vent area will have a one-inch or greater clearance.

As with any projector with a standard lamp, keep in mind the rule of thumb that the brightness will typically fall by about 25% in the first 500 hours of use, and then continue to decline more slowly.
One easy way to counter the loss in brightness as the lamp ages is to set the projector up with an image size that will give you suitable brightness in the Low lamp mode. You can then boost brightness as the lamp ages by switching to High mode. Another strategy--which you can use by itself or in combination with the first--is to start with one of the lower-brightness predefined modes, then switch to a brighter mode when you need to. With most projectors, that would also mean switching to a noticeably lower level of color quality. However, the HW45ES has good enough color in all modes to make this a far more acceptable strategy.
