  • WorkOS - The modern identity platform for B2B SaaS
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • SaaSHub - Software Alternatives and Reviews
  • OSCAR

  • The schematics are available [0]. It looks to me like the MCU is doing some sideband control, but the DisplayPort signal itself is passed through unmodified.

  • hdcp

  • https://github.com/intel/hdcp

    Grab it now before Intel deletes it completely.

    HDCP is really a very ugly protocol designed just for anti-copying, I wouldn't build anything relying on it, and everything is harder with HDCP from an AV integration perspective. If you have long links that you want to secure, use something like SDVoE with encryption and authentication (bits are easily flipped in HDCP).

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • kvm-switch

    Control hardware KVM/Matrix devices when your mouse moves to the edge of the screen (by timgws)

  • I had the same issue with this device. I ended up writing some code that you could run on a machine to operate the switching via the RS232 port: https://github.com/timgws/kvm-switch/

    Bonus for adding 'glide and switch' functionality, so you can move the mouse to the edge of the screen and it would jump the input to the next display in your layout. It's like a hardware version of Synergy.

    Very finicky device, but if you don't touch it - and you don't use any of the shortcuts - it works.
