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'm using the Samsung HDMI-HDMI cable provided with the monitor.

Ah, your MacBook has a HDMI port. What will happen if you connect the display via USB C instead?

I want to buy the monitor but I am afraid of this probpem as I also have the same Mac. Have you tried connecting two inputs as Picture in Picture (two sides) and merge them in Mac as in this link

Thanks - I didn't know this. I got it working now using different ports 👍

NextCspr is it correct that you managed to achieve 7680 x 2160 resolution by the use of the ”Hyper Drive Dual 4K HDMI 10-in-1 USB-C Hub connected to the correct usb-c port?

I don't have an M2 chip, I have an M1. So I cannot achieve the 7680 x 2160 resolution with a single HDMI cable.

Gotcha. Didn't know that was a further limitation (of the M1 Chip).
