Hi,

I am a user of adv7513 (HDMI transmitter).

 

Now i am trying to transmit 1920x1200, 27Hz video data, but it dosen't work.

(In case of 1920x1080, 30Hz, Full-HD, it works well.)

 

HDMI receiver recognized H: 1920 and V: 1080 like full-HD format.

 

Recognized V sync timming by HDMI receiver: V total 1250, V active 1080, V front porch 2, V sync 5, V back porch 163 lines.

 

For the HDMI trasmitter, is there any I2C command for video resolution setting?

 

To solve the problem, please give me hand.

 

Thanks.
