Question about HDMI (Typ A) — mini HDMI (Typ C) - 407080

"Max. Resolution of 1920 x 1080 pixels."-Astonishingly, however, it appears under the "4K cable" filter. Or am I misunderstanding something? Besides, I'm currently using a resolution of 3840*1020 with this cable, it would also support 3840*2160, which unfortunately doesn't do anything on my 5120*1440 - and this setting is not accessible. But I don't know why (yet).
