    My flow below,
    

    // Enter auto graphics mode.
     I2C_Master_Transmit(0xA0 >> 1, 0x01, 0x02);
     I2C_Master_Transmit(0xA0 >> 1, 0x00, 0x07);
     
     // Generate the pixel clock.
     iValue = 0x0898;
     I2C_Master_Transmit(0xA0 >> 1, 0x16, (uint8_t)(((iValue >> 8) & 0x1F) | BIT7));
     I2C_Master_Transmit(0xA0 >> 1, 0x17, (uint8_t)(iValue & 0xFF));
     
     //Configure the expected free run line length.
     iValue = 0x01A8;
     I2C_Master_Transmit(0xA0 >> 1, 0x8F, (uint8_t)((iValue >> 8) & 0x07));
     I2C_Master_Transmit(0xA0 >> 1, 0x90, (uint8_t)(iValue & 0xFF));
     
     //Set the expected number of free run lines per field.
     iValue = 1125;
     I2C_Master_Transmit(0xA0 >> 1, 0xAB, (uint8_t)((iValue >> 4) & 0xFF));
     I2C_Master_Transmit(0xA0 >> 1, 0xAC, (uint8_t)((iValue & 0x0F) << 4));
     
     //Configure the interlaced or progressive parameter.
     I2C_Master_Transmit(0x44 >> 1, 0x91, 0x80);

     //Set input color space1
     iValue = I2C_Master_Recieve(0xA0 >> 1, 0x02);
     iValue &= ~0xF0;
     iValue |= 0x70;
     I2C_Master_Transmit(0xA0 >> 1, 0x02, iValue);
     
     //9. Adjust digital clamping position2
     iValue = 0x40;
     I2C_Master_Transmit(0x44 >> 1, 0xC8, iValue >> 5);
     iValue = I2C_Master_Recieve(0x44 >> 1, 0xC9);
     iValue &= ~BIT6;
     I2C_Master_Transmit(0x44 >> 1, 0xC9, iValue);
     iValue = I2C_Master_Recieve(0x44 >> 1, 0xCA);
     iValue &= ~0x0F;
     I2C_Master_Transmit(0x44 >> 1, 0xCA, iValue);
    

    

    I want to use auto mode to output 1920x1080 resolution(1080P).
    

    Also I refer to example 3 in the file 4251.ADV7844_ADV7842_Autographics_Pr0_031109-1.pdf.
    

    But it's not working, what steps am I missing?
    

    Thank you.

      Hi,
      

        Today we evaluated the '1920x1080p' resolution in our ADV7850 evaluation board & It is working fine with below connection setup,
      

           VG-804B (Source) ---> ADV7850 Evaluation board --> VA-1842 Analyzer (Sink).
      

        If required, Please let me know i will share our UART log for your reference.
      

        Could you please check our Software driver for VGA configuration for non-standard mode.
      

        Now We are trying to configure the register for 1080p according to "ADV7842_Autographics_Pr0_031109-1.pdf"
      

      

      Thanks,
      

      Poornima

        Could you please change example configuration to RGB 32bit because our MB not support RGB 24bit.

        Hi,
        

        There are only 24, 30 and 36 bit color modes not any 32 bit color modes unless you are talking about ARGB colors in the code.
        

        It is possible to do 24 bit YCbCr 422 with 12 bit depth but I don't think you are talking about this since you mentioned RGB
        

        Besides the ADV7850 only handles analog or HDMI streams, not any digital streams.  
        

        Please clarify the question.

            Hi,
            

               We have given the configuration as per Autographic document ("1080p Component. 1920 X 1080 Active Pixels. 2200 X 1125 Total Pixel. Pixel clock = 148.5MHz").
            

               Could you please check with our ADV7850 evaluation board.
            

               Else request our source code project for the EVAL-ADV7850EBZ here & Compare your configuration with our software driver.
            

            

            Thanks,

              Hi,
              

              

              We have got the ADV7850 EVM board.
              

              So, how can I verify the Auto Graphic Mode function?
              

              I use the sw AVESBlue below:
              

               
              

              

              How to use auto graphic mode with ADV7850 EVM board?
