I have two macbook, MBP16(2019) and M1 Air.

When I connect one of them with LG 38WN95C Ultrawide Monitor by TB3 cable, HiDPI working differently:

M1 Air: HiDPI option is working as internal display.
MBP16(2019): Same as Ventura 13.1 Broke my External Display Re… - Apple Community

I have tried reset SMC, NVRAM and clean install Ventura 13.2 for MBP16.

But It still does not support HiDPI for other resolutions which is not default resolution.

MacBook Pro 16″, macOS 13.2
