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

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

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.

The Samsung G9 57" requires HDMI 2.1 for the full resolution while using a Mac. You will need a mac with an M2 Chip or better. That being said, even if you do have an M2 or better, MacOS currently does not scale well at that resolution and everything will be extremely tiny and hard to read at full resolution until apple fixes it.

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?

The key is to use TWO ports out of the Mac, to support what the Mac sees as two displays side-by-side. That Dock can NOT support Two half-displays on a Mac, because it is a USB-C Dock, good for only ONE display up to around 4K resolution best case.

There is NO MAGIC in that particular Dock.

If you used a genuine Thunderbolt port, Cable, and Dock, that might be able to support both half-displays on one genuine ThunderBolt port out of the Mac.

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.

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

cables 'shipped in the box' are notorious for being ":lowest bidder" cables. Just good enough to keep you from returning the product to the store the day you get it.

HDMI resolutions above 4K REQUIRE a certified ULTRA cable. Nothing less will do the job on a Mac.

The Mac checks for errors in transmission, and more recent MacOS checks more aggressively.

M1 is NOT supported.

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.

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.

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.

When you attach a large display to a MAC, the graphics are displayed at full native resolution of the display. PROVIDED that is achievable with the cables and adapters your are connecting. Most common and shipped in the box HDMI cables are Grossly inadequate for this job.

If your Mac can not attain an ERROR-FREE connection at the specified resolution and refresh rate, a lower resolution may be used, or the display may go blank.

M1 (plain) only supports up to ONE external display, so that display can not be supported on M1 (plain).

M1 PRO and MAX support two and four external displays, respectively. So the TWO-cable approach could be made to work on those models.
