Managing Aspections

By Craig, CTS 3D CDT, elert Associates proliferation extensive display of the proposed new burdens on those who support and end-user training, they make presentations in classrooms, lecture halls, and the Board of Trustees . As more and more into wide-screen projector application, the burden will only get larger. Preparation and management of the end-user expectations, they are jumping to a wide range of areas (the person or have it forced them) is very important for the smooth (ER), introduced a system of users and those who support them.

Widescreen is not monolithic standard. There are a lot of broader aspects of the resolution in the market - from 8 52x480 to a 920x1200 or even higher. Investigation and calculation method of monitoring choices at your local big box retailers will reveal 16:9 aspect monitors, and 15:09, 15:10, and other similar shapes. Pixel appears to be the size of 15:09, seems to be more common in the smaller (<20 ") in the aspect desktop monitors, and 16:9 is more common in the larger size displays.

Resolution projector along the application of more than by size. Cheap home-theater projector is often 1280 x720, which is 16:9, but has been less than the vertical pixel XGA (1024x768), so most of the computer images, scale / vertical squeeze, it seems that these projectors. Big / add / WAN expensive projectors tend to the 1365 x768 or higher resolution, it is less, and image scaling.

Show that the high aspect ratio, often referred to as the proportion of width to height. This is not a common standard, so never hurts to make sure your architect or screen vendor, you and they have a common understanding, screen size and shape.

Below are some common scenarios involving wide-screen adaptation, with the interpretation of what might have happened, and why.

Scenario 1: widescreen sources, the traditional (4:3 aspect) display.

An instructor, his extensive connections, laptops, introduced the system and signal that through traditional monitor or projector, in a wide range of areas format. Constraints in the width of this image is displayed. Because the image is displayed over a few lines or pixels, the image is relatively compressed, but it will leave gaps in areas above and below the image, the majority of monitors.

, digital section 1 A Figure 1, B No. 1 A hypothetical figures show that equipment (monitor or projector), and can show a wide range of aspects of the source. Many 15 ", 17", 19 "4:3, the LCD is not - they give you a blank screen, and to inform you that through the screen display signal is null and void (Figure 1 B ).
