Tool/software:

Hello,

  • Is it possible to use this setup to test the daisy chain feature with the following setup:

PC -> EVM 983 -> Display with 988 -> Display with 988 -> Display with 988

    Hi Franz,

    Yes this is possible by using the 98x daisy-chain. The Display boards would need to have output to display (OLDI) as well as daisy chain outputs to connect to the next deserializer. And they can be connected in Y-split or straight line daisy chain configurations. 





    Also, note that since there are multiple displays, presumably with different images, the 983 input can either be:
     - SuperFrame input. Where each display section is cropped (and vertically filtered if needed)
     - or DP Multi-Stream Transport with multiple video streams over the same DP link


    Ans to use the PC as a source for this test, you would need a GPU that can be configured to force custom resolutions, such as the NVIDIA Quadro.

    Let me know if you need any further information about these tests, we have done similar demo setups.

    Best regards,
    Ikram
