If a different display is connected and the new display does not support
the previously used resolution, the next possible resolution selection
will be automatically selected. If only one resolution is possible, the
resolution will automatically be activated.
• Standard Definition (SD)
Interlaced video is a method for reducing the bandwidth of a
video signal. To decrease the size of the signal, each video frame
is split into two sequential fields, one containing the field’s odd
lines and the other containing the field’s even lines. The frame
rate is then equal to 1/2 the field rate. Standard Definition video
(interlaced video) is susceptible to deinterlacing artifacts.
Standard Definition resolution uses less bandwidth, is typically
a 480/576i (interlace) low resolution digital signal and displays
at 30 frames per second (NTSC) or 25 frames per second (PAL).
• Progressive Scan (PS)
Progressive Scan (PS) indicates that the frame is not split into fields,
but is sent as a single entity. Progressive Scan picture quality has
more detail and less flicker than Standard Definition.
Progressive Scan displays at a resolution of 480p (progressive) at 60
frames per second for NTSC, and 50 frames per second for PAL.
• HD 720p displays a high definition 1,280 by 720p resolution.
• HD 1080i displays a high definition interlaced format with a
resolution of 1,920 by 1080i.
Display Aspect Ratio (Setup : Video : Edit Display Profile : HDMI Out :
Display Aspect Ratio)
Display Aspect Ratio is used to define the aspect ratio (width to
height) used to display the source video.
For optimum performance, select the aspect ratio that matches the
aspect ratio of the associated display. For example, a 64-inch wide
by 36-inch high screen has a 16:9 aspect ratio and a diagonal screen
dimension of nominally 73 inches.
DVDs come in various formats to accommodate different aspect ratios.
You can optionally adjust the Zoom Ratio to eliminate black bars that
may appear if the DVD and display aspect ratios do not match.
Generally, the display aspect ratio setting is a one-time set-up, whereas
Zoom Ratio settings for eliminating black bars may change based on
viewing preferences and the particular format of the DVD.
