Customizing the Nº502 Mark Levinson
Resolution
The Resolution parameter identifies the video resolution, either interlaced
or progressive, of the output signal. Interlaced video reduces bandwidth
by loading only half of the frame at a time; first the even lines, then the
odd lines. Progressive video loads the whole frame in sequence, providing
better picture quality but also increased bandwidth usage as the frame rate
is doubled.
The available Resolution selections are:
• Standard Definition – uses interlaced video at 480i or 576i.
• Enhanced Definition – uses progressive video at 480p or 576p
resolution.
• High Definition 720p – uses progressive video at 720p resolution.
• High Definition 1080i – uses interlaced video at 1080i resolution.
• High Definition 1080p – uses progressive video at 1080p
resolution. If the Component Video Output is selected, then this
option is not available for selection.
For optimal results, we recommend setting the Resolution
parameter to the format that matches the native format of the
video display. The resolution conversion of the input source material is
then performed by the Nº502, using its state-of-the-art video processing
technology, rather than by the video display, which may not have the
same processing capabilities. If necessary, refer to the documentation
included with the display to determine its native resolution.
Note Resolution is a preference setting – if the preferred selection is not available,
then the Nº502 selects a different resolution level. For example, if the
Resolution is set to 1080p but the output is set to Component Video, the
Nº502 outputs at a 1080i resolution level. The display EDID can also affect the
allowed Resolution settings.
Output Frame
Rate
Selects the frame rate of the output signal. The Output Frame Rate
identifies the number of frames transmitted per second. Available
selections are 50Hz or 60Hz. For 1080p resolution, 24Hz is also available.
Zoom Ratio
The Zoom Ratio parameter is used to fill the display area, reducing or
eliminating the black bars resulting from letterboxing or pillarboxing.
Before adjusting the Zoom Ratio parameter, ensure that the Nº502 has
been properly configured to match the aspect ratio of the associated
display by verifying that the Display Format parameter is set to the proper
aspect ratio.
Available selections include:
• Normal – select when no zoom is desired.
• Widescreen – select when using a 16:9 display and the source
material is widescreen anamorphic with a 2:35:1 aspect ratio.
