ad9389b not working with some monitors

I'm having trouble getting the ad9389b to work with all monitors.  There are several monitors that I've tried that work fine, but others will either display a shifted video (possibly with artifacts) or no video at all.  Below is the i2c  registers.  It's configured for 720p60.  I need this figured out quickly since we're planning to ship this system to a customer.
