Hi ,

    I have configured the EDID settings for in  DOC-1745 .In this EDID  (device address:6C ) device registers details not mentioned in the "ADV7611 SOFTWARE MANUAL".Any document is their for to refer this EDID registers details.


If i connected hdmi cable from phone or laptop means RXA_5V comes properly.But other Signals not come.

CABLE_DET_A_RAW, IO, Address 0x6F[0] -> Raw status of Port A +5 V cable detection signal.

While i was reading that regisgter 0x6F i got 0x01-> Cable detected on Port A (high level on RXA_5V)

But clock lines from HDMI cable ( RXA_C+,RXA_C-.) and  Data lines (RXA_0-,RXA_0+,RXA_1-.RXA_1+,RXA_2_,RXA_2+ pins.) not come.


In ADV7611 i got following clocks after loaded our I2c Software

LLC=72.468 Mhz





After that i connected our LCD(1280x800) ,it will show only white Blank screen.

Another one method also  i was checked the  Default colour pattern .Following settings configured and check the Colour pattren ,but colour was not displayed our LCD that time also LCD will show only white Blank screen.

{0x44, 0xBF, 0x16 }, /*MAnual Free run color select */

{0x98, 0x04, 0x62 },

{0x44, 0xC0, 0x6a },

{0x44, 0xC1, 0xdd },

{0x44, 0xC2, 0xca },
