How to Display WUXGA on a 1080p Projector

With the growing popularity of 16x10 displays, and in particular, WUXGA (1920 X 1200), we are commonly asked how to display a 16x10 source on a 16x9 projector. The obvious answer is to use a 16x10 or WUXGA projector! But, due to the overwhelming popularity of 16x9 displays (primarily 1080p), upgrading to a WUXGA projector is not always an immediate option.

There are basically 3 options:

    1. Resize the 16x10 image and squeeze it into the 16x9 display, distorting the aspect ratio of the native image, making everything look a bit short and fat.
    2. Resize the 16 x 10 image, leaving black bars on the left and right side of the image.
    3. Display "native, cropping the bottom 120 lines (or 60 lines at the top and 60 lines at the bottom) of the WUXGA source, and display it as 1920 x 1080.
    Option 1 -- Resizing and distorting the aspect ratio, is the least desirable option, as distorted aspect ratios are confounding to view.
    Option 2 -- Resizing the image so it fits within the 16 x 9 window, will allow the viewers to everything on the big screen that exists on the computer, but may result in a serious loss of image detail because of the amount of resolution that has to be discarded in the resizing.
    Option 3 -- Cropping the bottom 120 pixels (or 60 at the top and bottom) will provide the full horizontal resolution and 1:1 sizing on the vertical, just missing the last 120 lines, or top and bottom 60 lines. The 120 lines not displayed represent only 10% of the total vertical resolution, and these areas are often used for menus on desktop. Unless the application requires the operating system menus to be visible, this solution provides the best overall image.
