When youre trying to dial the image into your screen and your unique home theater setup, it can be confusing because of the sheer number of variables in play.However, by proceeding methodically and changing 1 thing at a time, you can dial in your projectors image by doing the following.
![]() In fact, those details you need to know are exactly what the rest of this article is all about. And most problems with fuzziness are simply small mismatches between where the image is in focus vs. In most instances, people like to project at least a 100-inch diagonal image on a projector screen. ![]() That slice of the light beam from the projector where the image has been expanded just enough that it looks good always exists. When you first turn the projector on is when you use the focus ring to move that slice of the light beam where the image looks good back and forth. If youre still pre-install, we have an article discussing the throw ratio and some calculations you can do to get it right. If part of the image youre seeing is in focus and looks correct, but other parts of the image are blurry, or if the entire image is too blurryfuzzy to even allow you to dial in the focus, then this could be an issue with the lens of the projector itself. The most common being fingerprints, which leads to dust collecting on the lens as mentioned above. If the projector has ever been disassembled, dust could actually be inside the lens causing the problem, but thats much rarer. If that happens, though, you just have to wait for the projector to come back to room temperature naturally. Dont just use any piece of cloth to clean the lens, you can seriously damage itfollow our step-by-step guide to cleaning a projector lens. That said, if you havent installed the projector yet, here are some reasons its important to find that centerline. Or rather, the range of distances its designed to project at. If you cant fix blurriness or fuzziness in the image by the methods above, then its time to physically move the projector back and forth until you find the right distance from the screen. To help out here, we have a calculator you can use for that. So start by determining which one you most likely need to play with. As discussed above, its hard to mess up mounting the projector on a center-line with the screen, but maybe you have a smoke detector or some other ceiling feature blocking the right center-line spot. Horizontal keystone correction fixes this by manipulating the image before its projected. Whether the projector is mounted above or below the screen, vertical keystone correction can be used to adjust the image to fit the screen even though the projector is projected from an unexpected angle. If the colors of a scene look off to you, then adjusting the sharpness can also help get that under control. Stay at it, and remember theres a lot of variables you might need to adjust, and then re-adjust later after youve changed other settings.
