Run DDU to completely remove all remnants of your current NVIDIA, AMD, or Intel graphics drivers.
Ensure the port configuration matches standard parameters, or try toggling UPnP (Universal Plug and Play) on or off to see if your router handles the traffic better. To help narrow down the exact cause, please let me know:
: The host computer uses a legacy processor or integrated GPU (e.g., Intel HD Graphics 4000 or older) that lacks full, native DirectX 11 or hardware encoding support.
: Outdated or broken graphics drivers on the client device disrupt the handshake between Parsec and the operating system's hardware acceleration API.
If the above solutions do not resolve the -14004 error, the Parsec logs will provide a much clearer picture of what is happening. parsec error 14004
The client may fail to decode if the host's resolution is too high for the guest device to handle.
If operating a headless server without a monitor, plug a hardware dummy plug (virtual monitor emulator) into the host GPU. This tricks the graphics card into thinking a display is active.
Outdated display drivers can break the connection link between Parsec and your graphics card.
