Dear, Freescale,

 

I develop HDMI input driver for ADV7481(HDMI receiver).

Freescale cpu : i.mx6 dual

setting resolution : 720 x 480 480p

pixel format : V4L2_PIX_FMT_UYVY, YUV422 8bit

HDMI device : iPhone, SAMSUNG Galaxy 3 and 4.

 

When I check LCD, it displayed quarter screen as attachment file.

So, I change resolution and pixel format but I check same screen.

 

For test, when I use CSI interface it displayed normal screen.

 

And, I use iphone 5s for checking HDMI because, galaxy 3 and 4 didn't display screen.

When I use iphone, it displayed quarter screen.

Also, When I use Android pad, it displayed quarter screen.

 

Thank you,
