According to ChatGPT:
Yes - the Samsung Odyssey G9 (G95C) monitor does support NVIDIA G-Sync technology (or, more accurately, "G-Sync Compatible"). Here are the concrete details, and also some precautions to take.
✅ What's confirmed
According to the product sheet from a Swiss retailer (Galaxus): "Sync-Technology: AMD FreeSync Premium Pro, NVIDIA G-Sync".
Galaxus
A specialist website states that the monitor supports variable refresh rate (VRR) up to 240 Hz for "FreeSync / G-Sync Compatible".

On the Samsung US website, for a slightly different model ("G95SC"), the information sheet states "G-Sync Compatible".

⚠️ A few nuances and conditions
"G-Sync Compatible" means that the monitor does not necessarily have NVIDIA's "certified" G-Sync hardware module (like some displays with a dedicated chip), but that it is validated to work with G-Sync via VRR. This may lead to differences in operation or compatibility.
An NVIDIA forum thread reports that for this "G95C" model, G-Sync mode does not work at 240Hz via HDMI, but only via DisplayPort at 240Hz. Via HDMI, it would only work up to 120 Hz.

Other feedback (DisplayNinja site) suggests that activating VRR (FreeSync or G-Sync Compatible) can cause flicker in some applications, indicating that performance can vary depending on settings and content.

🎮 My practical advice
If you're thinking of using this monitor with a VRR-compatible NVIDIA card (PC) or console :
Use DisplayPort 1.4 rather than HDMI if you want to take advantage of 240Hz and G-Sync Compatible.
In the NVIDIA control panel, enable "G-Sync Compatible" for this monitor.
In the monitor's OSD menu, make sure that "Adaptive Sync" or "VRR/FreeSync" is enabled.
Check in game that the frame rate varies within the supported range and that you have no undesirable effects (flicker, latency, etc).
If you're using HDMI and you're only doing 120 Hz, keep this limitation in mind.
I used it for programming for several months, but its curvature made it uncomfortable to use.
I sold it and bought a Dell UltraSharp U4924DW instead.
The large number of connections (USB, LAN, DisplayPort, HDMI, ...) makes it the perfect monitor.
Hello, I didn't get a VESA adapter and as far as I found out, it's not that easy to get one. (because of the special shape in the rear part) I think there are a few suppliers who offer one from the 3D printer. I then milled/drilled one myself from aluminium because I wasn't sure how stable this adapter would be.
If you choose an adapter, make sure you check which screens it fits. (Most of them say: "not compatible with the G95C")
According to our information, the LS49CG950EUXEN and LS49CG954EUXEN are technically identical models with different distribution channels. The LS49FG910EUXEN has a VA panel with 240 Hz, but lower brightness and HDR performance. The CG95 offers the better overall picture quality.
A faulty product image has probably crept in here, this is the VA version of this monitor.🫡 I will forward the misleading product image to the responsible department, thank you very much for the hint!
