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!

Grant Bennet-Alder correctly pointed out that the dongle is not what makes this setup work; instead, it's the use of two USB-C outputs from the MacBook. To streamline my desk setup, I replaced the HyperDrive with two new cables.

HARDWARE UPDATE:

Samsung Odyssey Neo G9 57-inch monitor (S57CG952NU)
MacBook Pro M1 14-inch 2021 (NKL4L4TXRW)
2 × USB-C to HDMI UHD 4K 3840x2160p 60Hz cables

NOTE:

If the color schemes on the two screens don't match exactly after connecting, try selecting the top-most color scheme on both inputs and then reboot the Mac.

Setup update without a HyperDrive:

HARDWARE:

NOTE:

If the colors on the left and right sides of the monitor seem off, performing a device restart while the monitor is connected should help!

Although graphics are generally displayed at full resolution, in most cases the TEXT (only) on large display tends to be unreadably small without Scaling. You use the Displays Preferences/Settings pane to control TEXT Scaling:

14" M3 Max MB Pro with 16-core CPU, 40-core GPU, 16-core Neural Engine.

I am using a 2-year old USB C to DisplayPort 4K@60Hz Cable from Amazon and I can achieve full 7680 x 2160 at 60 Hertz. I run at 6016 x 1692 which is comfortable for me for productivity.

Amazon USB-C to DP Cable: (WORKS for 8K @ 60 Hz) https://www.amazon.com/gp/product/B089N461TC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I also purchased a Cable Matters Braided 48 Gbps Ultra HD 8K HDMI cable and have tried the Samsung HDMI cable. Both produce unacceptable, need I say horrendous, results. Resolution changes (lowers) when the monitor wakes from sleep, waking from sleep takes close to a minute on my 57" Odyssey and when I tried it on my friend's 57" Odyssey (he got it about 3 months after me), the monitor will not even wake from sleep even though the MacBook is awake. Even worse, when connected via HDMI, I have experienced the following problems:

1) Blurring of anything on the screen - see attache photo - looks like wet paint that got wiped with a rag

2) Full screen of snow in which you can see all 8 panels

3) Black line from top to bottom on right side

4) Doesn't really sleep - continually wakes up every 30 minutes or so, looks at the ports and then says it can't find a source and goes back to sleep. Screen lights up twice in the process first with a message in the upper left hand corner and then with one in the center. End result, monitor goes back to sleep.

Are you using a dock or a direct cable to connect your Mac to the display? If you're using a dock, Try using a direct cable (USB C to USB C or USB C to HDMI) instead. If you're using an USB C cable make sure that you use one that is suitable for displays and that is not only a charge cable

Dec 17, 2023 1:43 PM in response to NextCspr

@NextCspr - what resolution and refresh rate do you get on your MBP - which Modell and Processor to you use? Furthermore what is your viewing distance ? I am a bit afraid the because the monitors natural resolution is not a mac native one.

Dec 17, 2023 2:51 PM in response to NextCspr

HDMI cables you want for HDMI-only Displays (higher resolutions than 720p TV sets) are marked as Certified with an anti-counterfeiting tag and are labeled:

"Premium High Speed HDMI cable" or that + "with Ethernet" --OR--

"Ultra High Speed HDMI cable" or that + "48G"

Cables with No Certification tags are good for your standard 720p TV set, and not much more.

HDMI was invented for HD TV sets. it works great at its original resolution of 720i or 720p. At higher resolutions, it quickly develops issues that are complex to solve, and the cables and adapters required to solve are NOT intuitive.

@NextCspr - are you using it with a MacBookPro M1, M2 or M3 processer - I read a story that you need to have at least an M2 above to make it to the native resoution of the monitor via HDMI. I am wondering very much on how the picture might look like since the Displays resolution apparently is not a native resoution of MacOS and the PPI of the Display is way below the Apple Displays e.g. not Retina like. So how would you describe the picture quality e.g. sharpness and readability? THX

Like mentioned in the post it's a Macbook Pro M1 14-inch 2021 (NKL4L4TXRW). And as mentioned I can only see resolutions up to 5120 x 1440, which is what I'm using currently. Viewing distance isn't really in question. I just want the higher native resolution of the monitor. The picture is bad as the resolution is not high enough.

Yes. But the problem is I cannot get a proper native resolution on both inputs at the same time when using picture in picture mode. Also the color scheme is off between the inputs.

I am using a Hyper Drive Dual 4K HDMI 10-in-1 USB-C Hub to connect HDMI1 and HDMI2 from my Samsung monitor.

So far nothing has worked. I do believe the root cause being the M1 chip. I cannot say if better docking stations could make a difference.

Absolutely Fabulous NextCspr. I was not sure if I should even consider the monitor anymore - anyway I ordered it directly with Samsung - November 24 - expected delivery 8. December - did not arrive - they lost it somewhere and Samsungs can not resolve the matter. However, now I think this could work with the setup you outlined! Thanks again!

Yes - I can achieve the 7680 x 2160 native resolution of the monitor at 60 hertz if I connect the MacBook to the monitor directly via HDMI-HDMI and connect the MacBook "indirectly" to the monitor via the HyperDrive (HDMI to USB-C).

Apple has been quite slow in support for non-Apple device resolutions. Before Sonoma there wasn't even native support for 5120 x 1440 so I ended up giving up my previous Samsung Neo 49" G90 to someone from Facebook Marketplace. This new and almost unique resolution will need to wait for Apple action and I guess it will be very, very long.

Wish you happiness to your smart workaround.

<<. Apple has been quite slow in support for non-Apple device resolutions. >>

Your statement as written is NOT correct.

Samsung Neo 49" G90

5120 by 1440

display interfaces:

displayPort 1.4 and HDMI (2)

That display can be connected to ANY Apple Silicon Mac and work at its full resolution, using an adapter to DisplayPort for any model, or using HDMI alone for M2 and later models.

I have the 49" Samsung G9, native resolution is 5120 x 1440. I have a brand new Mac Studio M2 Max, with lots of processor power etc. I cannot get this running on a single cable - only the dual (with one being crappy quality!)
