HD with 1350 total lines don't work on DVI.
1) What does work? Standard formats
2) What CEA861E VIC number are you trying work with. As far as I can tell there is no standard format with 1350 active lines or total lines.
3) Which input are you using?
thanks for you answer.
The active resolution is 1920x1080 with 2200 H-Total and 1350 Lines at 148.5MHz.
All i2c read register (fieldheight, rbidentLCF ) have correct results.
On the output side the CLK (148.5 Mhz) and V-Sync (50Hz) is ok, but H-Sync is unstable and DE is missing (low).
All other inputformats starting from 800x600 up to 2560x1536 and everything between works perfect.
2) What CEA861E VIC number ...
??? What is the issue ???
Same behavior on both DVI inputs.

So you want 1080p50 input which is VIC #31. VIC #31 defines Htotal = 2640 and Vtotal=1125 and VCLK = 148.5MHz. not what you've shown above. From you number above you've reduced your horizontal blanking interval and increased the vertical blanking interval to get you 1920x1080 resolution at 50 Hz
i need to display the timing descripte above.

I'll check into how to handle a custom input format for the ADV7441A
From the factory, since we don't have any specific scripts for this format the suggestion was to use autographics modes and adjust DE and VS controls in the CP core first
