Cannot open display. zcu104

I created linux application in Vitis that should take a picture from the camera and display it on the screen. I use opencv for image input and output. I connected the monitor via displayport. The monitor displays a messages when loading Linux. I launch my app using the terminal. The camera image is saved to a file, but when I try to display the image on the screen, I get the message " GTK-warning**: 13: 26: 17.285: cannot open display:".

I used the export DISPLAY=:0 command, but i get "cannot open display:0".

Please help me solve this problem.

Thanks

I have the same error currently. Using a Zybo Z7-10 (Zynq 7000 series).

I'm using v2019.1, however.
