Locked to 30HZ,
I've tested this both on my LG 4K TV and my 4K Monitor. UGREEN Revodok Pro USB C Hub with 4K60Hz HDMI, 10Gbps USB C&A 3.2, 100W Power Delivery. I have a 100w power adapter going into it.. when i plug into both tv or monitor, it shows 4k signal, but its locked to 30hz and in both instances i have black bars, for 16:10 ratio, makes black bars top, bottom and sides.. for the tv its just the sides. Has nothing to do with aspect ratio, autoscan.. it is the active signal that is wrong.
This hub on paper, should be compatible, or am i missing something.. i've tried two different hubs that both say they fully support 4k 60hz, but to no avail.. only USB C to C has worked.
