Hi there!

I'm having a look into creating a FPGA system with purely open standard and open source IPs (as well as open source code on my part). So far I have landed on a really good journal article looking into different open source IPs for the RISC-V open standard here: https://ieeexplore.ieee.org/document/8760205.

But now I have realized that I need some sort of display interface and can't find anything! I have read that DisplayPort is open-source, but I am pretty sure this only relates to the interface protocols and not the actual hardware itself. I may be wrong on this but I haven't been able to easily find anything on their standard licensing rules, other than a licence for their logo and brand name which doesn't seem very compatible with the ethos of the project.

Perhaps USB-C is the best solution.

Is anyone aware of any display interfaces that I could implement? I do not have a lot experience in video interfaces so would like some suggestions from people who likely know a lot more than I do :)
