maybe you can help me with my g-sync problem:

I use my new PC (7800X3D, ASUS B650e-f, MSI RTX 4090 Ventus, Win 11) with 3 identical LG OLED 4K/120Hz 48-inch TV screens (model C1 from 2021, with g-sync compatibility) and I want to have g-sync with all monitors of course.

G-sync works wonderfully on the HDMI output of the 4090 and HDMI 2.1 input of the monitor, in full 10-bit RGB, HDR.

However, g-sync is not recognized on the two screens that are connected to the DisplayPort output of the graphics card (with a monitor input also to HDMI 2.1).

Unfortunately, the "g-sync menu item" is missing in the Nvidia Control Panel and "Monitor Technology" does not appear under the global 3D settings. The monitors connected via DP work in "HDR RGB 10bit full" but with a FIXED 120Hz.

I am not sure whether its the cable: I use one with DP1.4 -> HDMI 2.1 specification, see amazon: AGFINEST DisplayPort 1.4 to HDMI 2.1 8K cable.

Or could I fix this with CRU changing something at my TV settings (What & How)?

Thanks for your help as I am lost.

You need active adapters that support converting HDMI VRR to DisplayPort adaptive sync.
