Regarding wrong format detection of ADV7604

Hi,

 

We have configured ADV7604 in Analog mode and providing VGA signals via DVI-I connector from Windows 7 machine.

 

Though we are providing 1600x900 video resolution from source, chip is detecting it as 1280x960 resolution. Following is the details status of chip.

 

Can anybody please help us here ?
