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

HDMI Version

2.1

The highest DisplayPort refresh rate shown as supported for Full 8K width is 30 Hz.

M1 Macs feature HDMI 2.0, which directly supports up to 4K display width.

To run this essentially 8K wide display on an M1 Mac over ONE cable, you would need to use a DIRECT ThunderBolt connection (which the display does not support) or use two cables.

TWO Cables:

On the Mac, you set up two half-width displays, and arrange them in an order that puts then side-by-side.

on the display, you use the Picture-By-Picture feature (cousin of Picture-in-Picture) to have the two half-displayc coming in on two cables placed side by side on the screen.

You do not need these two cables to be the same protocol -- one can be HDMI and one DisplayPort, or any combination.

Readers report this works near-flawlessly.

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!

FYI I am able to get 7680 x 2160 @ 120 Hz with one certified ultra high speed HDMI 2.1 cable going straight from the monitor to my HDMI port. I was able to get this with the HDMI cable that shipped with monitor as well. The only drawback is not being able to plug in the monitor directly into the hub, but I'm totally cool with that given the benefits far outweigh the trouble. No splitting the monitor into sections or anything like that.

I have a M2 Max.

Sometimes though when returning from sleep, the max res converts to 5120 x 1440 @ 60 Hz. A quick restart fixes this. A bit annoying but it is what it is for now.
