Hello
It seems like you’ve already done the necessary steps to keep your Surface Book 2 running when the lid is closed. However, the issue you’re experiencing might be due to how Parsec interacts with your Surface Book 2 when the lid is closed. Here are a few suggestions that might help:
HDMI Dummy Plug: One user on Reddit suggested using an HDMI dummy plug. This device tricks your computer into thinking there’s a monitor plugged in, which might keep Parsec active even when the lid is closed.
Virtual Display Driver: Another suggestion from the same Reddit thread is to turn on the “virtual display driver” in Parsec. This creates a virtual screen that Parsec can cast to, which might solve your issue.
Check Power Settings: Make sure that your power settings are configured correctly. In addition to the “Do nothing when the lid is closed” setting, you might also need to adjust other related settings.
Surface Book 2 Design: The Surface Book 2’s design might be causing some issues. The radio and antenna are in the tablet portion of the device, so you might get better performance with the tablet up. Additionally, closing the lid could cause mechanical and radio frequency interference.
