Display Ratio Letter box Repeat Mode Sequence Video■ Display Ratio
Select the display ratio of the Video.
- Letter box: If the video source does not fit a 16:10 screen then the video image is stretched equally in the horizontal and vertical directions to fit the screen.
Therefore parts of the video are cropped at the top and bottom (left and right) sides and appear as "black bars" around the video. - Cut screen: Choose to display the video in its native resolution without scaling. If the projected image exceeds the screen size then it will be cropped.
- Full screen: Regardless the native aspect ratio, the video image is stretched non-linearly in the horizontal and vertical directions to exactly fit the 16:10 screen. You will not see the "black bars" around the video image but the proportions of the original content may be distorted.
- Original screen: Choose to display the video image in its native resolution without scaling. If the video resolution is lower than 1280x800 then you will see "black bars" around the edges of the video image. If the resolution is higher than 1280x800 then the video is displayed in 1280x800 resolution.
