Hi ,

  

      There is a issue when I connect to a  laptop( only Dell Inspiron ,Mackbook and Dell Latitude both fine) which works fine with TV.

   On EVAL board ,It works fine when power on, but after switching input two or three times,

   the TMDS   DC voltage level is gone( as the picture below).Is ADV7625  can't  turn on more than three  Rx termination at the same       time?
