ZCU102 Display port settings for different aspect ratio

Dear,

Basic on ZCU102 TRD 2018.3 Vivado design and I import the example of "psu_dpdma", it work properly for 1920x1280 default resolution setting.

I also try to modify below code to be XVIDC_VM_1280x720_60_P, it also work properly. But after I try to modify it to be XVIDC_VM_640x480_60_P, it could not work properly and the monitor could not detect any signal.

Any other settings should be modified for different aspect ratio from 16:9 to 4:3 ?

Please help, thank you.

 

void InitRunConfig(Run_Config *RunCfgPtr)

{

..

RunCfgPtr->VideoMode = XVIDC_VM_1920x1080_60_P;

...

}

Hello p.ching.kuang@gmail.com 

Tested monitor list for DisplayPort controller is provided at https://www.xilinx.com/support/answers/68671.html

I will recommend first try one of this monitor to test at your test resolution.

It is possible some of DisplayPort based monitor cannot be supported by DisplayPort controller. 

Moreover, There are any message on your monitor (like" Cannot display this video mode'?")? Please check this document for supported resolution and FAQ section.

Regards,
Bhushan
