Hi,

I have a probem with the ADV7343. the device is programmed with this value :

    {0x17,0x02},

    {0x00,0x12},

    {0x01,0x00},

    {0x80,0x11},

    {0x82,0xC2},  //0xc2

    {0x87,0x80},

    {0x88,0x10},

    {0x8A,0x0C},

    {0x8C,0xCB},

    {0x8D,0x8A},

    {0x8E,0x09},

    {0x8F,0x2A},

 

My component is a Pixlworks device and I send to the ADV7343, 720x576 pixels active and the clock is at 27MHZ. ( 50Hz / 15.625Khz )

 

The display is OK but not the shape. When I send a circle, I display an oval. I don't understand why the display is not a circle.

 

Thanks for your help
