"No Video Input" message on the monitor running Display port design example for Arria 10 SX SoC

Hi,

I am stuck trying to test Display Port on my Arria 10 SX SoC board. I need TX only design example.

I tried to download full design example from Intel/Altera web sites, but mostly they are for older Quartus versions or for FMC daughter cards. I want to test Display Port onboard connector. 
 
My Quartus version is Quartus Pro 25.1, device - 10AS066N3F40E2SG1

Also I tried to generate design example in Platform Designer and I succeeded to receive EDID from monitor and it seems that handshake is done, but I see only "No Video Input" message on my monitor.

I spend more than a week discovering the issue and I assume that PMA settings might be wrong or incorrect link rate/clock frequencies.

Thanks in advance for any help!

    If anybody worked with Display Port on Arria 10 SX SoC or any other devkit, could you please share how to calculate/find PHY settings for the onboard DisplayPort? Or it is just an iterative process?

      Hi valentyns,

       

      The official Arria 10 design example is for the Arria 10 GX Dev Kit using the Bitec DP daughter card.

       

      There is a design example for Arria 10 DP using the onboard connector for TX only, available in the FPGA Design Store. You may try out this design example. Please note that the Quartus version provided is 16.0.0, so you will need to perform an IP upgrade when migrating the design to QPDS Pro v25.1. Additionally, the design example targets the Arria 10 Dev Kit, so you will need to migrate it to the SoC board that you are using.

      Thanks.

      Best Regards,

      Ven

        Hi Ven,
        Thanks for your reply!

        I have already tried to download that example, I successfully upgraded IP cores in Quartus Prime 18.1 Standard and synthesized design, but there is no software at all.

        Do you have a full example for Arria 10 DP using the onboard connector for TX only? 

        Best Regards,
        Valentyns
