OK all you quality video TV tech aficionados...need some help/tips...

I have a Vizio M60-C3 circa 2016 model (bought late in '16) https://www.vizio.com/m60c3.html

Last night I picked up a new 4K Apple TV in hopes of getting the best out of everything. The Apple TV settings let you select from a vast array of picture qualities, 4K HDR, 4K SDR, 180 HDR, 1080 SDR, and so on, and so on down the line; you get the picture (no pun intended, LOL). It also offers all these settings in various Hz starting at 60 and working down.

My TV has multiple HDMI connections labeled "4K @ 30 Hz" and one connection labeled "4K @ 60 Hz (1080P and Higher)".

First question would be which should I be using?? but read on...

I've been playing for two days now and here are some results...

- The Apple TV will not let me select 4K HDR @ 60Hz (even when plugged into the lone 60 Hz port)

- It will run the 4K SDR @ 60 Hz, but the picture is not as good as 1080 HDR @ 60Hz (when plugged into the lone 60Hz port) or some of the other settings. Confused by this!

- So far, the best picture to my eyes is the setting 4K HDR @ 30Hz (when plugged into one of the 30Hz ports)

- I haven't done a side by side comparison between this and the old Apple TV (4th Gen [the one right before 4K], thus 1080 capable), but I'm wondering if my TV itself is the choke point and I'm not gaining too much from the 4K box, even though it's a 4K TV.

- My biggest hurdle at this point is not having a clue about the HDMI ports on the TV. What's the difference between the 30 vs 60Hz and how does that effect things? Could use some info there maybe.

Anywho...thanks for any help guys and let me know if you need more info to try to build a better idea for me to get the most out of this.

As far as I know, the only way to get true 4k@60hz is to use an actual display port, due to bandwidth restrictions of HDMI, even at 2.0. I know on my 4k monitor for gaming, HDMI can not handle anything higher than 30hz at 4k, but will do 1080P@100hz fairly easily. 4k@60 takes a lot of bandwidth.

It also says your 5th HDMI port may be able to handle UHD@60
