Which would provide for a smoother gaming experience, 120hz with VRR disabled or 60hz with...

When I set it to 120Hz by overriding it, the VRR option gets grayed out. When I set it back down to 60 Hz, i can enable VRR again. On 60Hz with or without VRR enabled, there is no stuttering. I also have tried all of these iterations with free sync enabled and disabled on my monitor.

Your Xbox series X supports 1440p @ 60hz. However, you can only use it if your monitor supports it. If you're playing in 1440p I would personally recommend the 120hz for smoother gameplay experience.

May I also point out that to enable VRR (Variable Refresh rate), you also need VRR capable TV or monitor.

VRR works on both 60Hz and 120Hz.

Does your monitor support both VRR and 120Hz on Xbox? I have read that only specfic monitors out there support both enabled. For awhile the VRR was only supported at 60Hz but there are some monitors now that will allow you to enable both VRR and 120Hz.

I recommend keeping all of those 3 options enabled. When supported, Dolby Vision will provide superior image quality, but regular HDR will still provide a better picture than SDR. VRR should also remain on, this will make your gameplay feel smoother in games that support 120Hz or unlocked framerates.
