Odyssey Neo G7 - Triple Monitor Display - Page 2 - Samsung Community

JBlack002 · ‎01-26-2023

I recently purchased 3 Odyssey Neo G7 32" monitors (4k) to replace 3 Odyssey G7 32" monitors (1440p) I've had for a couple of years. I use the monitors as a triple display on my driving simulator. I run a Windows PC. I can only get a display on 2 of 3 of the Neo G7 4k monitors. All monitors work individually, but only a combination of 2 of 3 present a display when attempting to display to all 3 simultaneously. The monitors are each connected individually via DisplayPort 1.4 cables to a corresponding port on the RTX4090 graphics card. Windows recognizes the 3 monitors (in display settings) and that they are connected to the graphics card (Nvidia RTX4090), but one monitor is noted as "inactive". The RTX4090 is not the problem. I tried a different RTX4090 and get the same result. I'm convinced it's something with the Neo G7 4k. Incidentally, I never had any issue when I previously ran triple monitors with the previous G7 1440p monitors.

The Neo G7 4k is described as "gaming monitor" just as the previous G7 1440p was. Both 32" with 1000R curve with focus on PC gaming. The Neo G7 is an enhancement with greater resolution and HDR support. Otherwise, they are marketed in a similar fashion. It will be a huge disappointment if the final word is that the Neo G7 4k cannot support triple displays. The marketing materials provide no such disclaimers.

I have discussed this with Samsung via live chat (#89887375). I was supposed to hear back, but so far nothing.

Considering your experience I'd return the G7's and purchase a different brand that will do 4k @ 120hz and be done with it.

I having the same issues.
Odyssey Neo G7, but using RTX 4080.

I did get it working but not ideal.

IN the monitor settings (within the monitor itself) I had to set two monitors to 120 Hz, and left the third on 165Hz.
Windows 11 would then display all three Monitors.
Not sure why I had to do this, and hopefully there's a better solution.

I tried that too. Set all 3 monitors to 120hz within monitor's onboard app. No go for me. I also reduced resolution to no avail.

I tried lots of things. I built a new PC (i9 13900, RTX 4090, Windows 11 Pro) specifically to run triple 4K monitors. I wondered whether it was a Windows 11 issue, so I hooked up my previous computer (i9 10900, RTX3080, Windows 10 Pro) and experienced the exact same issue. I had run triple 1440p monitors (Samsung Odyssey G7) on this PC for 2 years with no issues. A lot of the feedback I've received expresses the opinion that it's a Windows issue. I'm doubtful. I've watched several videos of PCs with the RTX4090 running triple 4K monitors, although none have been the Odyssey Neo G7 or G8. My bet is it's the monitors and a firmware update is needed to resolve whatever the issue is.

Sorry to hear that.,

I did re-install Windows from Scratch, but also tested before hand and what I did for both works.

I'll list what I did below in case anyone else buys these monitors for triple screen setup.

One thing in my Monitors were two had firmware 1003, and one had 1004.
There was no listed firmware upgrades on Samsung Australia, and most other sites I checked. But Reddit to the rescue, and someone posted firmware 1006 from Korean site...
I applied these, so all were the same firmware version.

One thing when I was testing, I found I had to use DDU to completely uninstall NVidia Control centre.
Then re-installed after a reboot.

My settings in the monitor:

Game Mode on
Free Sync on
Set resolution to 120Hz

Then in Nvidia Control centre, accept the default resolution and 120Hz for all three monitors.
In Windows set to HDR, and then installed the Microsoft HDR Calibration tool, and calibrate the monitors.

Back in Nvidia Control centre, go to each monitor and create a custom resolution. Configured at 1440p (2560 x 1440) at 144Hz.

Then when into the Surround, and enable that.
It set the resolution at 11,520 x 2,160 at 120Hz.
Once it does that, then you can go back to the setting, click the little icon beside the resolution and select 7,680 x 1440 at 144Hz (7,680 is 3x 2560)
Interesting it picks this up, and so far testing no issues...

(Ignore the set-up, testing before mounting on Triple screen monitor mount)

I tested with 2560 x 1600, but decided to keep with 2560 x 1400)
