Processing time in the graphical output device (15 – 100 ms, where 15 ms
are only reached with CRT tubes)
The majority of the delay, between 85 and 230 ms, is not a consequence of the
extender-system. The extender system is responsible for 5 -15 ms mouse
movement/ transmission to the CPU plus 15 – 45 ms acquiring the graphic data and
transmitting it to the Remote Unit. Our measurements show that time delays greater
than about 100-150 ms become noticeable and bothering. Therefore, if an extender-
system increases the mouse signal delay from, say, 100ms to 140ms you may begin
to experience the “elastic” delay problem.
If you use a slow response TFT screen you may already have a total response time
of up to 175 ms, right at the threshold level. The addition of an extender line to such
a system will appear to cause the “elastic” mouse delay problem even though the
extender system is responsible for only a small part of the total problem.
Hint: Use a display with a shorter response time (please note: the response time
indicated by the manufacturer is a measure of how quickly two successive pictures
can be displayed, not how long it takes for a signal from the input interface to reach
the screen). Use a lower resolution or a background which can be compressed
better: Please avoid photo-backgrounds or colour gradients – single-coloured
backgrounds are optimal and permit highest possible compression rates. If the
transmission needs to drop frames (because the RLE compression algorithm does
not reach the required data reduction) you need to add approx. 17 ms @ 30fps and
approx. 34 ms @ 20fps
USB-HID-devices
Your USB-HID device does not work
Although our interface supports HID devices, we can’t ensure that every connected
device will operate successfully. If you have any compatibility problems, please
contact our technical support.
Other USB-devices
Your USB- device does not work
You have connected a non-HID device. The extender system supports HID devices
only. All other devices are incompatible with the CATX DVI-D Switch system.
