Chrome Remote Desktop: DXGI Output Duplicator Errors

Hello,

I’m running into a persistent problem with Chrome Remote Desktop on my LG gram laptop.
Specs:

• Intel 13th Gen Core i7 (with Intel iGPU)
• NVIDIA RTX 3050 4GB (Optimus / hybrid GPU setup)
• Chrome browser version: 139.0.7258.155
• Chrome Remote Desktop Host version: 140.0.7339.17
• Devices: Connecting from an iPhone (Chrome Remote Desktop iOS app version 101.0.4951.27 latest version).
• Displays: Two extended monitors

The Issue
Previously, when connecting through my iPhone, I could see both displays and control them seamlessly. After recent updates (Chrome or OS), it now only shows one display, and mouse/keyboard movements are offset to the other display, making it essentially unusable.

When I check the debug.log inside the host folder, I keep seeing these warnings:

[0903/103455.930:WARNING:third_party\webrtc\modules\desktop_capture\win\dxgi_duplicator_controller.cc:286] Failed to initialize DxgiAdapterDuplicator on adapter 1
[0903/103455.930:WARNING:third_party\webrtc\modules\desktop_capture\win\dxgi_adapter_duplicator.cc:116] Cannot initialize any DxgiOutputDuplicator instance.

[0903/103455.953:WARNING:third_party\webrtc\modules\desktop_capture\win\dxgi_duplicator_controller.cc:106] Count of references reaches zero, DxgiDuplicatorController will be unloaded.

What I’ve Tried

• Updated Intel + NVIDIA drivers (not clean install yet - not sure if it would make a difference).
• Reinstalled Chrome Remote Desktop host.

Still no luck — CRD fails with the same error every time.

Has anyone else run into this exact DXGI error with CRD on a hybrid Intel + NVIDIA laptop?

• Did a clean driver install fix it for you?
• Should CRD always be forced onto the Intel GPU in Optimus setups?
• Any other tricks to get DXGI duplication working again?

Thanks!
