Was playing around with the #MacMini. Hooked up #HDMI to my #4K monitor expecting to be able to use a scaled resolution (in my case, 3072x1728 #HIDPI). Wouldn't work. Only worked in #LODPI. Then I read this article - a little disturbing. Apparently the M4 can't run HIDPI 4K across HDMI. But I CAN run it with a dumb TB -> dongle -> HDMI setup like I was forced to do on the Macbook Air (due to no HDMI port). For real?! That is fucking STUPID. https://forums.macrumors.com/threads/for-lg-oled-users-mac-mini-m4-does-not-support-hidpi-4k-over-hdmi-2-1.2442797/
For LG OLED users: Mac mini M4 does not support HiDPI 4k over HDMI 2.1
EDIT: 4k @120HZ is working with M4/M4 Pro. This thread is about running at a scaled/downsampled "looks like" 3840x2160 resolution, which is not currently supported on M4. I am starting a new thread with all known information about the lack of 4k HiDPI support with the M4/M4 Pro Mac mini, as...
