Assuming you are using single data rate communication for the video data, Register 0xBA (Clock Delay) allows you to adjust the position of the rising edge of the clock compared to the data.
Based on the information in the programmer's reference guide, it appears that you can delay the rising edge of the clock relative to the data by 1.6ns (0xBA[7:5]="111") or accelerate (negative delay) the rising edge of the clock relative to the data by 1.2ns (0xBA[7:5]="000").
I hope this helps.
