@Lildog55 Blackmagic makes what you need. Also be aware that HDCP can cause issues so you may need to get an HDMI splitter/HDCP stripper. Also EDID can be problematic on some devices. Look into that as well.
@C418 I’d recommend avoiding @AnkerOfficial like the plague. They were spying on their customers and sending unencrypted feeds from their “security”cameras over the internet. After they were caught, they lied about it and still haven’t apologized.
