Hello. I tried my best Google-fu on this with mixed success.

So I hooked my deck into my 4k TV that’s displaying at 4k 60hz and it was locked at 30 fps, thought that was odd so I switched it to 1080 60hz and still locked at 30fps. I changed it to 2k 120hz and now it can hit 120 fps. So why can’t I set it to 60 hz and get 60 fps?

Maybe a weird 59hz thing? Not sure. Any help would be great.
