Hi ,

    I have configured ADV7611 and hdmi inputs given from laptop/phone either one.Output side LCD 1280x800 was connected and output images are little different from input.I have mentioned for both Laptop and mobile phone resolution values and issue below.

 

   Test1:->HDMI input From LAPTOP to ADV7611

   Horizontal Total line Length=0x672 (1650),Line Width =0x500 (1280),Horizontal Front Porch  =0x6E(110) ,Horizontal Pulse Width =0x28(40),

  Horizontal Bach  Porch  =0xDC(220)

   vertical side field0 details:

  vertical Total Height=0x5DC (1500),vertical Height=0x2D0 (720),vertical Front Porch  =0x0A(10) ,vertical Pulse Width =0x0A(10)

  vertical Bach  Porch  =0x28(40)

    Vsync=60Hz

   Hsync=45KHz

    LLC Clock=74 Mhz

   DE=43.26KHz

  This above resolution input coming (1280x720) from Laptop and output of LCD image little bit overlapped after full image displayed from 1280x720.

  I have attached images please refer Image1 for Laptop overlapped issue.

 

Test2:->HDMI input From Phone to ADV7611

 

Horizontal Total line Length=0x898(2200),Line Width =0x780(1920),Horizontal Front Porch  =0x58(88) ,Horizontal Pulse Width =0x2c(48),

  Horizontal Bach  Porch  =0x94(148)

  vertical side field0 details:

  vertical Bach  Porch  =0x1E(30)

   Vsync=90Hz

   Hsync=45KHz

   LLC Clock=74 Mhz

   DE=43.26KHz

  I have attached the LCD display image while iam playing from phone pls refer Image3.

 

I tried images from phone to LCD means that image shows on LCD.

But i tried to play video from phone to LCD means via ADV7611 i got HDCP Unauthorized content Disabled.Please refer image Image2.
