Unable to write frame to HDMI out

I have built this block design trying to send one frame - .png file to monitor via HDMI, using PYNQ-Z2 Board

generate bitstream succeeded, i moved the .tcl , .bit , .hwh files into SDcard along with .png file that i want to display to monitor.

now i know have several options to do that but do not how.
a) using Ovelay
b) using Vitis.

can anyone explain the required steps to do this?
thanks.
