ryans I suppose the question is where to start, as at least in my case it's happening on Smart TV's/Games Consoles/PC's.
I think almost everyone here would agree having a strain-free PC/Mac is the absolute #1 priority. Following that IMO would be Smart Phones, then Games Consoles and then Smart TV OS etc etc.
So we'd need to contact the major players, Intel, Nvidia, AMD to at least get the driver side sorted out. If we can get a bonafide dithering-free GPU/Driver then that's a big part of the puzzle resolved. Next would be to analyse the OS itself, and contact Microsoft/Apple (sigh) for assistance. Following that, once we know a dithering/artifact free OS and GPU is in operation, the only remaining point of failure is the display itself, perhaps icc profiles/edid spoofing could fix that.
To gain media attention is a different story. I know many are against reddit and other forms of social media but that is the platform of the masses. Facebook groups, reddit channel, even youtube channels in my opinion are essential to raise awareness of these problems. I'm not suggesting any clickbait tactics (Iphone XR made me blind 🙂).
