Another setup consideration is that even slight misalignment of any of the projector’s corners can result in highly noticeable keystone issues, which is to say UST projectors are extremely susceptible to producing trapezoidal-shaped images. Most UST projectors have two or more adjustable feet to help you align the chassis with the wall, but they have far fewer manual lens adjustments (like lens shifting and zoom) than many similarly priced traditional projectors. Most of them do have electronic keystone adjustment, which digitally shifts the image to correct the shape, but this reduces the number of pixels used to create the image and thus reduces resolution and image clarity. It’s a shame to pay more for a 4K resolution, only to lose the benefits in order to set up the image properly.
