Projectors with laser light engines offer a significant advantage over a bulb-based system in a long-term projector blended installation. However, Edge Blending can’t be combined with pixel shifting but that is okay in many situations where maximum flexibility is more important than absolute resolution. The result is an image that looks seamless, like it’s being displayed by a single projector. You can use the projector’s Black Level setting to make the difference even less noticeable. Under the Blend Range menu’s sub-setting, you can fine-tune the blend’s starting position and the width of the blended area. If you need more light output or want to utilize multiple projectors to display a larger, wider aspect image, many projectors are equipped with several features to make that goal easier.īy utilizing Edge Blending, you can split an image over multiple projectors and display it as one large image while reducing the hard transition from one projector to another. For more information on Lens Shift check out the technical blog we wrote several years ago. So, the bottom line, variable Lens Shift is the best way to keep your image rectangular unless you can place the projector right where it needs to be. Also, the amount of vertical adjustments applied affect the amount of horizontal adjustment available. Normally 3LCD projectors have a larger range of available lens shift than a comparable DLP model. A projector may offer both horizontal and vertical lens shift but the amount of overall adjustment can vary by projector type due to various internal layouts of projectors.

Lens shifting moves the lens itself up and down and left and right within the projector’s chassis to align the projected image to the screen. If you can’t move the projector, lens shift is the preferred way to correct keystoning issues because unlike electronic keystone correction, it doesn’t affect resolution. The result: a wide image at the top and a narrow image at the bottom. Since the distance to the top left and right corners of the screen is farther from the lens than the bottom left and right corners, the image spreads out more. A projector typically sits on a table so that its lens is about even (or slightly below) the bottom of the screen. We all have been in rooms where the image was much wider at the top than the bottom, that trapezoidal shape is usually referred to as Keystoning. PAL (B, D, G, H, I, M, N, 576i/p), NTSC (M, 4.43/3.When a projector is properly aligned with the screen the image will be “perfectly” rectangular.
