I have my Linux box running my TV and it works great, but I’d like the ability to treat my Chromecast as a desktop window for streaming without switching inputs, multitasking etc. I have an HDMI capture card that works great with a Switch, but the Chromecast detects it’s not HDCP (DRM) compliant so it won’t work. Is there a way to outsmart that detection with software or hardware?

I’ve heard some knock off hardware confuses it enough to work but it seems like the info is old and I’d rather not roll the dice on hardware that’s otherwise garbage…
