Hi,
I'm back :(
I use "AXI4 to video out" for SDI stream video (with SDI to Video bride -> Video to AXI4 -> YCbCr to RGB -> AXI4 to Video and a Video Timing Controler/Generator).
At the final I can lock and get Hsync and Vsync only in landscape mode (1920*1080). When I switch to portrait ( I use my computer), i get an underflow !
Any suggestions?
Thanks

Hi @pgrangeray,
I would use a VDMA or speed up your stream clock.
I guess when you use 1080 x 1920 (portrait) the HSYNC and HMARGIN are slightly reduced compared to 1920 x 1080 (landscape). So you might need a stream a bit more faster.
But this is only a guess.
