Cause
When multiple displays are connected, the screen drawing
performance is lower than it is for a single display. This phenomenon
is a limitation and there is no workaround. Improvement is planned
for a subsequent version.
The screen drawing performance may also be reduced when a 4K
display is connected. The recommended resolution is 1920×1080 or
other HD resolution. Review the display settings.
You can set the volume level of the microphone used for streaming
output and video conferencing on the [Setting] screen and the video
conferencing setting dialog. If the volume is still low when the level of
the microphone is set to maximum, change the Microphone Boost
setting. The Microphone Boost setting must be changed in Windows
OS after logging in as an administrator.
The video conferencing function does not support 1920×1080
resolution. Set the output resolution to 1280×720/29.97 using the
SYSTEM SELECT switch on the rear of the SRG-120DU.
When finished, reboot the SRG-120DU and the main unit.
The SRG-120DU image may freeze or suffer other symptoms
depending on the quality of the USB 3.0 cable. In this case, try
replacing the cable.
The SRG-120DU transmits an uncompressed image signal using a
USB cable. Accordingly, the CPU performance can be significantly
affected, even when the image is not being displayed. Set the output
resolution to 1280×720/29.97 using the SYSTEM SELECT switch on
the rear of the SRG-120DU.
When finished, reboot the SRG-120DU and the main unit.
The SRG-120DU USB control (UVC Control) must be enabled. Set DIP
switch #2 on the rear of the SRG-120DU to ON.
When finished, reboot the SRG-120DU and the main unit.
On the main unit, keyboard shortcuts, such as the Windows button
and Ctrl+Alt+Delete, are disabled in order to hide Windows
functions. To enable these keyboard shortcuts for maintenance or
other purposes, use the following procedure.
1. Launch the Task Manager.
2. Open the [Services] tab.
3. Select and right-click the [MsKeyboardFilter] service.
4. Click [Stop] in the context menu.
