PROBLEM: THE MOUSE POINTER OF THE AGILITY REMOTE UNIT IS SLOW OR SLUGGISH WHEN MOVED
ACROSS THE SCREEN.
This issue is often related to either using dithering on the video output of one or more transmitting computers or using VGA-to-
DVI video converters.
Dithering is used to improve the perceived quality and color depth of images by diffusing or altering the color of pixels between
video frames. This practice is commonly used on Apple Mac computers using ATI or Nvidia graphics cards. VGA-to-DVI
converters unwittingly produce a similar issue by creating high levels of pixel background noise.
Agility units attempt to considerably reduce network traffic by transmitting only the pixels that change between successive
video frames. When dithering is enabled and/or VGA-to-DVI converters are used, this can have the effect of changing almost
every pixel between each frame, thus forcing the Agility local unit to send the whole of every frame: resulting in greatly increased
network traffic and what’s perceived as sluggish performance.
REMEDIES:
Linux PCs
Check the video settings on the PC. If the Dither video box option is enabled, disable it.
Apple Mac with Nvidia graphics
Use the utility for Mac’s – Contact technical support.
Apple Mac with ATI graphics
Enable the Magic Eye dither removal feature.
Windows PCs
If you suspect these issues with PC’s, contact technical support for assistance.
Replace old VGA adapters on host computers with DVI video cards.
PROBLEM: MY MONITOR IS DISPLAYING A PINK SCREEN
It is possible that the source computer and Agility local unit are sending a high resolution Dual Link signal in response to a
request from your Dual Link monitor. However, your Agility remote unit is unable to correctly process the signal, causing the pink
screen issue (DVI resolutions above 1920 x 1200 are generally Dual Link).
Agility Dual (ACR1002A-T) and Agility Dual VNC (ACR1012A-T) local units are able to send Dual Link video when requested,
however, an Agility Dual (ACR1002A-R) remote unit is required to process the higher resolution signal fully at the other end. Other
remote units, such as the Agility, and Agility Dual-Head units cannot process Dual Link DVI as they are Single Link devices.
Ensure that the Agility local unit is set to supply a Single Link EDID to the graphics card. When the video source is changed to a
Single Link video resolution, the pink screen should disappear and the video should be displayed normally. Alternatively, change
the monitor to a Single Link DVI monitor.
It is important not to mix Dual Link Local units with Single Link Remote units.
On an iPATH controlled system, ensure that the Video compatibility check is enabled as this ensures that the correct video mode
is displayed for the monitor being used.
