We went through a standalone DPDMA example (harden DP) on a customized Zynq Ultrascale+ based board, the debug print shows the test success but nothing shows on the monitor.
the monitor is DELL 2415b proven works with a Xilinx ZCU102.
The standalone program print output:
Xilinx Zynq MP First Stage Boot Loader Release 2018.2 Aug 13 2019 - 09:48:16 PMU-FW is not running, certain applications may not be supported. DPDMA Generic Video Example Test HPD event .......... ! Connected. Lane count = 2 Link rate = 10 Starting Training... ! Training succeeded. DONE! .......... HPD event Generating Overlay..... Successfully ran DPDMA Video Example Test
no changes to the BSP lib which the standalone program links against;
use new created FSBL with new created BSP lib
all projects use the same hardware project which created from our customized HDF;

Could you give some details about your monitor?
Is it a DP monitor (make sure you are not using an adapter)? What is the maximum supported resoution?
Maybe the application is trying to use an unsupported resolution

I believe you are following steps provided at https://forums.xilinx.com/t5/Video/Standalone-DisplayPort-on-ZCU102/td-p/892936 (Check for solution post by @florentw).
Kindly recheck on changing psu_dp driver from avbuf to dppsu.
Are you re-plugging cable or providing HPD pulse, after first run of application?
