Q
7. Why does my preview window blink?
The screen might blink if the screen frequency setting does not match the AC current. Please
open the Point of View, and click “setting” button. Choose “image control” tab and change the
setting.
For example: the frequency commonly used in the USA is “60 Hz”. See the list below for
additional listings
8. Why do I get the message: “ USB Controller Bandwidth Exceeded”?
When you deploy the PoV and are using other USB devices simultaneously, it may slow the
overall bandwidth. As a result, the “USB controller bandwidth exceeded” message will pop
up. Here are several solutions to consider:
a. Close the Point of View and reopen it again after you start your video conversation.
b. You can also lower the USB bandwidth of PoV. Open Point of View and click the “setting”
button, choose the “image control” page and change the USB bandwidth setting.
c. Please use alternative USB ports if required.
