I have a Win 11 PC - NVIDIA GTX3080 GPU connected to a CJ791 curved monitor. I have installed the monitor drivers from Samsung to the USB-C display port but when I go to my adapter settings I can only select 50Hz or 60Hz - however when I connect by HDMI I can get the full 100Hz. My graphics card appears to be usable for the USB-C port. What do I need to do so that I can hit 100Hz and still use the USB Hub features of my monitor?

Hello! Thank you for reaching out! Unfortunately using an adapter to use the USB-C feature can cause issues such as this to occur. As far as I know, I don't think most GPUs have a USB-C connector. At least I know my RTX 3080TI doesn't I would recommend trying a better adapter that supports USB-C 3.0. After that, I would recommend using the HDMI cable to be able to get the 100Hz.
