Hi, Now the VGA to HDMI board AD9984A+ADV7513 generates DE by setting the ADV7513 registers 0x35~0x3A,matching the input video resolution with VESA Standards to set these registers.
For example,if the input video resolution is 1080p,I set DE Generation registers according to the H Front Porch、Hor Sync Time、V Front Porch、Ver Sync Time in the VESA Standards table.
So if the input video format is somewhat different with VESA Standards(HSync / VSync Frequency deviation),the output video would be out of shape or move. Could you provide some help or suggestions?
Thanks a lot!
