Zephyrus G16 GU605CW dGPU External Monitor not recognized

[Ahvgust]

Hello

I have a problem trying to get my second monitor to work with the right side USB-C port on my Zephyrus G16 GU605CW (Intel 285H, RTX 5080). The left side port works fine, however I can't gonfigure G-sync on the second monitor, as it is controlled by the integrated graphics. The second monitor is AOC AG271QG (2K 165hz G-Sync). The right side port works fine for other devices, charging etc. 

Things I've tried:

Changing display modes from the Nvidia control panel

Changing performance modes from Armory Crate

Updating graphics drivers and BIOS to the latest version

Forcing dGPU only from the BIOS. 

Any suggestions to get the second monitor to work with the dPGU (right side port)?

After confirmation, the Thunderbolt™ 4 port on the right side of the GU605CW only supports iGPU output. According to the specifications, only the USB 3.2 Gen 2 Type-C port supports G-SYNC settings.

Additionally, if you want the second monitor to output via the dGPU, we recommend connecting it using the HDMI port. The above information is provided for your reference. Thank you.

Just to clarify, the Thunderbolt 4 port is on the left side of the device, when looking at the screen?

And the issue that I’m having is when I connect the external monitor to the USB 3.2 Gen 2 Type-C port (right side of the device) it doesn’t recognize the external monitor.

Additionally when connecting the monitor to the HDMI port, the maximum resolution is 1440p 60Hz (monitor supports 165Hz). I tried it with a PS5 original cable which should be adequate.

Any help is appreciated.

Thank you for the clarification, and I apologize for the misunderstanding!

Could you please record a video showing that the computer does not recognize the external monitor when it is connected to the USB 3.2 Gen 2 Type-C port (on the right side of the device)? Please also provide the following information via PM so we can further investigate. Thank you.
