Is this what you're looking for? I'm not really familiar with the technology but this looks like it's a close match if not an exact match.

There are tons of these with 4k support, but almost none with HDR. I have ordered one that does tho, but it came to $16 with shipping. I'm tempted to order a few random ones for $1-3 from China to see if any of them are writeable just to help others that are in need.
They are used for streaming in 4k hdr for people who doesn't have a display that supports this (but have a TV that does). The reason why almost all of them only support 4k no hdr , I think is because they are mostly used by cryptominers using gpus for mining..
A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
