Limited HiDPI resolution for M2 Max Studio's HDMI port?

[marco-prolo]

Hi, I am using the Pro version and have a problem where, when I use the HDMI port on the Mac Studio M2 Max, it changes the resolution when I enable HiDPI.
If I use an HDMI adapter on one of the Thunderbolt ports, HiDPI works without automatically changing the resolution. Which is great! However, then the colors and contrast of the image appear relatively flat. Please help.

Hi there, for most displays the M2 Max Studio will (annoyingly) limit the HDMI port resolution at 5K horizontally (that is 2560x1440 HiDPI for a 16:9 display). Try to use USB-C/Thunderbolt for better results.

Thank's for the clarification. I'm actually using a 21:9 1440p LG display.
When the Thunderbolt to DP cable arrives, I'll test it and give you feedback
