ADV7614 port D can't detect HDMI signal from Dell laptop?

     When connect the laptop's HDMI output to ADV7614 port A, the TMDS clock is detected, and both CABLE_DET_A_RAW  and TMDS_CLK_A_RAW is high. I tried another HDMI pattern generator(CPHD-3) and connected HDMI output of this pattern generator to port D, and everything's fine, too.

     However, when connecting the laptop's HDMI output to port D, the TMDS_CLK_D_RAW is always low. But CABLE_DET_D_RAW is high, which means the cable is detected when plugging the HDMI cable to port D.

     Is there anything I missed or anything special when using port D of ADV7614?
