Video Settings - Generation 2 Devices
1. Choose Video > Video Settings or click the Video Settings button
in the toolbar to open the Settings dialog.
2. Adjust the following settings as required:
a. Noise Filter
Devices can filter out the electrical interference of video output
from graphics cards. This feature optimizes picture quality and
reduces bandwidth. Higher settings transmit variant pixels only if
a large color variation exists in comparison to the neighboring
pixels. However, setting the threshold too high can result in the
unintentional filtering of desired page changes. Lower settings
transmit most pixel changes. Setting this threshold too low can
result in higher bandwidth use.
Note: The default Noise Filter is 4. Raritan recommends that you
lower this value to 0 (zero). Although higher settings will stop the
needless transmission of false color variations, true and intentional
small changes to a video image may not be transmitted.
b. PLL Settings
If the video image looks extremely blurry or unfocused, the PLL
settings for clock and phase can be adjusted until a better image
appears on the active target server.
Warning: Exercise caution when changing the clock and phase
settings since doing so may result in lost or distorted video and you
may not be able to return to the previous state. Contact Raritan
Technical Support before making any changes.
