4K 120hz Splitter or Passthrough?

I’ve been scouring the internet for a splitter that can do 4K 120hz (basically full HDMI 2.1) and for the life of me can’t find anything that does more than 60hz. There are switchers that can handle 120hz, but no splitters to output two signals at the same time

Has anyone found anything that can do this? Could also just be a usb capture device but, again, I can’t find any that passthrough more than 60hz.

Thanks!

Thanks for this info. Have you ever come across anything in the $100-$200 range?

Thank you!
