Samsung Odyssey Neo G9 57" monitor with Macbook Pro M1 (2021)

I am trying to connect my Samsung Odyssey Neo G9 57-inch monitor (S57CG952NU) to my Macbook Pro M1 14-inch 2021 (NKL4L4TXRW) as an external display. The monitor supports resolutions up to 7680 x 2160 @ 240 Hz but in the display settings of my Mac I can only see resolutions up to 5120 x 1440 even though "Show all resolutions" is enabled. I have also tried the app BetterDisplay with the same results.

I am wondering how I can achieve the 7680 x 2160 resolution. The refresh rate is not important for me.

My monitor has 3 × HDMI 2.1 (HDCP 2.2) and 1 × DisplayPort 2.1 (HDCP 2.2) outputs (DP currently in-use by my PC)
My Macbook has 3 × Thunderbolt 4 (USB-C) ports (up to 40Gb/s)

Or is it simply not possible to achieve the 7680 x 2160 resolution from my Macbook Pro M1?

Hope someone can help.

MacBook Pro 14″, macOS 14.0

I now have it working fairly well. Describing my setup below for people who are interested.

HARDWARE:

Samsung Odyssey Neo G9 57-inch monitor (S57CG952NU)
Macbook Pro M1 14-inch 2021 (NKL4L4TXRW)
HyperDrive Dual 4K HDMI 10-in-1 USB-C Hub (HDM1H)
Samsung Premium High Speed HDMI cable
Samsung Ultra High Speed HDMI cable

CONNECTION:

Monitor HDMI1 connected to MacBook HDMI port
Monitor HDMI2 connected to HyperDrive HDMI connected to MacBook USB-C

OS:

Sonoma 14.2.1 (23C71)

CONFIGURATION:

Monitor PIP/PBP mode enabled (left half HDMI1 input, right side HDMI2 input)
Apple -> System Settings... -> Displays -> Arrange...
Apple -> System Settings... -> Displays -> Oddyssey G95NC (1) -> 3200x1800 resolution @ 60 Hertz
Apple -> System Settings... -> Displays -> Oddyssey G95NC (2) -> 3200x1800 resolution @ 60 Hertz
Apple -> System Settings... -> Desktop & Dock -> Displays have separate Spaces -> Disable

CONCLUSION:

With this setup I am running an ultra wide resolution of 6400x1800 with HiDPI.

I could go up to a resolution of 7680x2160 (Default) but in my opinion everything becomes too small.

Thank you all for the assistance!
