I provide to AD9889B Hsync, Vsync and DE via external pin.

the parameters is :

Height           = 1920

HFront         = 88

HPulse        = 44

HBack         = 192

 

Width          = 1080

VFront         = 4

VPulse        = 5

VBack         = 41

 

clk = 148.5 -> 1920*1080p/ 60hz.

screen detected this solution but the pixels display on screen not right.

EX: line 100 - line 600 is the red pixels, but it don't the red pixels.

I think !

the frame video don't at center screen.

how to fix this?
