Troubleshooting
Since the V-44SW handles video with differing aspect ratios,
if you do not scale (enlarge/reduce) the input video to match
the output format, the screen aspect ratio may not display
properly.
For each input channel, set the “Scaling Type” parameter
under “3. HD/RGB Input” in the menu to adjust the aspect
ratio.
The screen aspect ratio may be distorted if the format of the
output video does not match the settings of the device
receiving HD output or RGB output.
➔ “About the Scaling Type” (p. 33)
There may be instances in which not all of the video output
from the V-44SW appears in the display. This may be due to
differences in the size of the region in which video is not
displayed (the safe area) for some displays. To adjust the
video size so that it does not reach into the safe area, set “5:
Zooming” under “1. Output” in the menu.
As the V-44SW inputs and outputs HD, RGB, and SD signals
in analog format, differences in color may occur, even with the
same video material, due to individual differences from one
device to another. Make the settings for each individual input.

● When using the screen transition effects (wipe or mix)
When using the screen transition effects (wipe or mix), the
video images may be disrupted at the moment the wipe or
mix effect is most fully applied. To prevent disruption of the
video, try switching the video after first switching
completely to the subsequent video.
● When using the P in P or key composite effects
Disruption of the video images may occur when the video
is switched while the sub-screen or key composite video is
displayed. To prevent disruption of the video, switch the
video after first switching off the P in P or key composite
effect.
Select “5. Key” from the menu and adjust the value of the “3:
Soft Edge” setting. If the value is set too high, portions of the
video not belonging to the key image may also end up being
masked.
Use video input that features a high signal-to-noise ratio. For
example, you can achieve better key composite results with
HD key images than with SD key images.
● When using the screen transition effects (wipe or mix)
When using the screen transition effects (wipe or mix), the
video images may be disrupted at the moment the wipe or
mix effect is most fully applied. To prevent disruption of the
video, try switching the video after first switching
completely to the subsequent video.
● When using the P in P or key composite effects
Disruption of the video images may occur when the video
is switched while the sub-screen or key composite video is
displayed. To prevent disruption of the video, switch the
video after first switching off the P in P or key composite
effect.
Selecting an HD/RGB channel to which no signals are input
may result in delayed switching of the video; this does not
indicate a malfunction.
● The cooling fan exhaust vents are blocked
Anything happening to impede the cooling fan exhaust
vents will prevent proper cooling of the V-44SW, causing
temperatures inside the V-44SW to rise. As this may result
in damage to the V-44SW, be sure not to place any
obstructions near the exhaust vents.
● Other equipment is stacked on top of the V-44SW
Setting other devices directly on top of the V-44SW may
result in heat from these devices being transferred to the V-
44SW, thus causing the V-44SW to overheat. In such
situations, be sure to provide adequate space between
other devices and the V-44SW.
● Debris is caught in the cooling fan exhaust vents
If any foreign matter happens to be caught up in the cooling
fan, it can cause audible noises from the interior of the
V-44SW, and may even lead to damage. Do not place any
object liable to enter the exhaust vent near the vent.
If something does get inside the exhaust vent and you are
unable to remove it from the outside, contact the nearest
EDIROL/Roland Service Center, listed on the back page of
the warranty card.
