No HiDPI scaled resolution for 4k/120hz on LG OLED TVs?

[zizhengwu]

I was able to get 4k/120hz working on my LG OLED C2 TV. I'm following this guide "DP/USB-C/Thunderbolt 3/4 to HDMI 2.1 4k@120hz RGB4:4:4 10b HDR with Apple Silicon M1/M2 now possible !"

However, I don't get HiDPI scaled resolution options. Did I miss anything? Also, I'm wondering if I should turn on HDR or not. Thanks!

I'm a fool. Looks like options without "(low resolution)" are actually HiDPI scaled resolutions. The new UI is a bit misleading.
