Question G-Sync Issues - LG24GN60R-B

[Marnad]

Hello,

Scratching my head here a bit but I'll try to be right to the point:

- recently purchased a 24 " LG monitor to use as an external display (model in the subject)
- I'm connecting to this monitor using the display port out on a Dell G15 laptop (mobile RTX 3060 GPU)
- using the DP 1.4 cable, I cannot seem to have the G-Sync option in the Nvidia control panel
- I've tried using both the "Basic" and "Extended" adaptive sync setting within the monitor OSD options (also power cycled the monitor)

As soon as I unplugged the DP cable from this external monitor, the G15 laptop display offers the G-Sync settings again within the Nvidia control panel. From what I read, I was under the impression that G-Sync worked on this LG monitor. Could I be missing a particular setting or maybe a firmware update?

Any help or insight would be greatly appreciated - thanks!

This may seem stupid or something and idk if this is true but I don't think you can get G-Sync through a laptops output even if it's DP connection. Unless that laptop has full fat DP 1.4 to DP 1.4 than I'm shocked by that as that's a first for me on Ampere Laptops. Besides that only a full fat GPUs' DP from a PC can display G-sync if the display is compatible................ Correct me if I'm totally wronged rn.....................

Hey there - thanks! You actually set me on the right path of troubleshooting. The Dell G15 was using a function called "Optimus" that blends graphical usage between the iGPU (Intel) and the discrete GPU (the RTX 3060 in this case).

After entering the BIOS and disabling "Optimus", I now have full G-Sync functionality on the external display.

Again, thanks for bringing this to light!
