When you open the
Video
submenu, the highlighting automatically moves to
the
Resolution
control.
4. Press Select to view the available Resolution settings.
The first option in the list is highlighted. The current setting is marked with an
asterisk.
The default setting,
480i
, results in an interlaced picture with resolution similar
to that of a conventional TV (but much greater clarity as a result of digital
processing and the component video interface). This is called Standard
Definition TV (SDTV) in the HDTV specification.
The second setting,
480p
, gives the same resolution but produces a non-
interlaced picture. This is better for fast-action video, and is referred to as
Enhanced Definition TV (EDTV).
The
720p
and
1080i
settings enable the media adapter to output a true HDTV
picture. While 1080i allows greater detail, 720p is preferable for rapid motion,
and is used by most HDTV stations specializing in sports broadcasts.
You should use a setting of
480i
for a display labeled SDTV,
480p
for an
EDTV device, and
720p
or
1080i
if you are sure your TV or projector has full
HDTV capabilities.
An “HDTV-compatible” or “HDTV-ready” TV or projector with a vertical
resolution other than 480, 720, or 1080 will “downconvert” or “upconvert” a
standard signal for display. It is best to use the setting that is closest to such a
device’s native resolution.
5. To try a different setting, move the highlighting to it in the usual way and
press Select.
The new setting is immediately put into effect, and you are automatically taken
back to the
Video
submenu, with
Resolution
highlighted.
If necessary, return to step 4 and repeat until the picture is satisfactory. Note,
if the only problem is stretching or squeezing of the picture, that this can
usually be solved in the next step.
6. If you have a wide-screen TV or projector, select Aspect Ratio and
change the setting to 16:9.
Use the up and down arrow buttons and
Select
as described above.
The default setting,
4:3
, compensates for the slight vertical elongation of the
pixels in a 480-line display that has a 4:3 aspect ratio. The
16:9
setting
compensates for the slight horizontal elongation of the pixels in a 480-line
display that has a 16:9 aspect ratio.
Again, the new setting is put into effect immediately after you select it, and you
are automatically taken back to the
Video
menu.
