LG LG 34WK95U-W / 34BK95U-W will NOT work as an HDR display with a maximum resolution of 5120 x 2160 with a MacBook Pro. It looks great as an ultrawide display without HDR.

HDR looks poor compared to being used as a standard 5120 x 2160 ultrawide display. HDR, which is only supported with DisplayPort 1.4, does not work properly on this monitor with macOS Catalina 15.5.4. 4: - When switching from DisplayPort version 1.2 (default) to 1.4 (required for HDR) when connected to a MacBook Pro, the LG display goes black and freezes. Switching from DP 1.2 to 1.4 only works if no MBP is connected. - Colors are less contrasting and washed out when using Catalina HDR mode. - In HDR mode, the maximum resolution is reduced to 3840 x 2160. This is a 16:9 format. Ratio, with black bars to the left and right of the display. LG and Apple need to do better driver optimization for macOS before this monitor can become a true 5120 x 2160 HDR display.
