Happened to me yesterday. I have an old 4K TV, every component I used to connect to it had HDMI 2.0+ capabilities. Neither laptop nor Steam Deck would output 4K60, only 4K30. Tried getting another cable and a hub, same result. And I know that my Chromecast outputs 4K60 to this TV, so I was extra confused. In my desperation, asked GPT-5 what was I missing, and it plainly told me that those old Samsung TVs turn off HDMI 2.0 support unless you explicitly turn it on in TV settings under “UHD Color”. Apparently Chromecast was doing chroma subsampling, but computers refused and wanted full HDMI 2.0 bandwidth…
I don’t think users actually write those. You just pick the amount of stars and the term is hardcoded for the amount. It most likely is just a translation mishap.
