@JColvin Thanks for replay, I'm using vivado 2018.2, i set my display resolution to 1280x720 on my laptop and duplicated the screen then set the same resolution on zybo and image is cropped, on function 8 it grubs full frame, strange red lines which appear on videos and photos seemed to be caused by axi stream subset converter where colors are swapped, i removed them and its now correct, i dont know why this color swapping is necessary there, other problem i have is that when i duplicate my screen it works but if i extend my screen then it cant detect hdmi anymore.
