FAQ-What Are the Differences Between the Three Display Modes for HD Output

Publication Date:  2015-08-06 Views:  341 Downloads:  0
Issue Description
I know the 9000 series videoconferencing endpoints provide three display modes (stretch, no stretch, and intelligent stretch) for HD output. What are the differences between those three modes when 4:3 video is displayed on a 16:9 display screen?
The differences are as follows:

Stretch: Stretches the video to full screen with an unfixed aspect ratio. The video becomes distorted.

No stretch: Stretches the video to full screen with a fixed aspect ratio. Black borders may appear on the four sides of the video.

Intelligent stretch: Crops the video to an appropriate size and stretches it to full screen, maintaining the original aspect ratio. For example, to change a wide-screen video to a narrow-screen video, your endpoint crops the left and right edges of the wide-screen video and stretches it to full screen.

If the video on the display screen is cropped, the output mode may have been set to Intelligent stretch. You can change the mode.
