4:2:0 resolutions can only be defined using TV resolution codes, so 72/96 Hz wouldn't be possible. 1920x1080 @ 100/120 Hz is theoretically possible, but that would require the driver to acknowledge 4:2:0 for those resolutions. I don't know about NVIDIA, but AMD wouldn't do 4:2:0 for 1920x1080 the last time I checked. Also, the HDMI 2.0 data block has a 30-bit (10 bpc) option for 4:2:0.

I don't think NVIDIA supports 10-bit output with VGA.
