I don't know. It says ThinkPad on top. It was provided by my employer.
Edit: Not directly related, but I turned off DRM support for similar reasons. Web sites keep turning one of my monitors off when that's enabled. Even though I'm not intentionally or perceptibly playing any media. The (well, another) weird thing is the other monitor stays on. They're the same brand and model, using the same cable.
Fancy hardware stuff seems to make browsers unstable, and in my experience this has been true for over a decade. I don't care enough about to try to find a root cause. I don't need DRM support or hardware acceleration for anything I intended to do, so I just turn off anything like that.
