I'm using the HDMI 1.4/2.0 Tx subsystem to display an image on a screen. I have interfaced this with the AXI VDMA and the image is the result of a custom image processing IP I have developed and packaged.
However, there seems to be a synchronization problem on screen where the (0,0) point of the screen is shifted. I have circled the 0,0 point on the image I have attached. I am also attaching a picture of the IP integrator block design.
The image is a 1024x1024 Image that I am trying to display on a monitor at resolution 1920x1080 @60Hz . For the HDMI interfacing I mainly use the code provided in the example design provided in Chapter 6 of PG235.
This is the block design. As I mentioned I have interfaced this with AXI VDMA and my own custom IP. I store the images on my DDR memory and display it from there. Even without processing I get the same sync issues.
Can anyone help me/ guide me in the right direction towards solving this issue so I can display the entire image on the screen?

Would you share your posted bd image as PDF file and video timing ?
