Subject: Countermeasure for failure when used with PCs equipped with hot plug detection.
Prepared By :

Tommy Jue

Purpose:

Original pin #9 of the video cable connection in PCB layout was connected to GND. This will cause error for
some PC systems when system pin #9 is connected to +5V. Cutting the trace on the PCB will resolve this issue.
