Dual-GPU laptops tend to have the integrated graphics be connected to the laptop's display, which is the one Parsec uses on the Computers tab for technical reasons. This means you're usually stuck with Intel iGPU or AMD APU's encoders, and cannot use the better NVIDIA encoder. Here's how you can work around that.

Use an external display or headless hdmi plug

External displays tend to be connected directly to the dedicated GPU, so hosting that solves the issue. Use either a proper external display, or a headless hdmi plug (which tricks your hardware into thinking it's an actual display).

Warp users: Use virtual displays

If you have Warp, there's a messy workaround involving virtual displays and disabling the integrated graphics adapter in Device Manager, to force the display to use the dedicated GPU.

• Open Device Manager
• Expand display adapters
• Right-click your integrated GPU and disable it

• Restart Parsec from the tray bar icon
• Turn on at least one virtual display in Parsec's settings

At this point, you can set up the displays to act in different ways. Choose the behavior you want to see when connecting below:

• I'm fine with my laptop's display being off while I use Parsec: Simply turn on Privacy mode in Parsec's settings, and connect to the laptop on Parsec

• I want to see content both on my laptop screen and Parsec: Ensure Privacy mode is turned off. Connect to the laptop on Parsec, and as soon as you join, press Windows+P on the original machine before you get kicked out from Parsec and choose "Duplicate".
• I want the Parsec display to be a secondary screen: Ensure Privacy mode is turned off. Connect to the laptop on Parsec and it should just work like that. If not, press Windows+P on the original machine before you get kicked out from Parsec and choose "Extend"

In some cases, you may keep getting error codes even when doing the steps above correctly. If that happens, restart the laptop and try to connect to the laptop again.
