Raspberry configure on DMT FHD videomode

   tvservice -s

   state 0x120006 [DVI DMT (82) RGB full 16:9], 1920x1080 @ 60.00Hz, progressive

 

On attach configuration sequence for ADV7613 in file adv7613_init.txt. Command send through I2C interface.

 

Self made board connected to LED LCD N156HGE-L11 througth Dual LVDS. In attache some photo LCD output. Colors and sizes of picture elements match the original (full_view.jpg in attach), but it has a distortion which is clearly seen in the images (top_corner.jpg and bottom_corner.jpg)
