# parsec-vdd
|
|
Standalone **ParsecVDD**, create virtual display without Parsec, upto **4K 2160p@240hz**.<br>
|
|
|
|
<br>
|
|
<br>
|
|
<br>
|
|
|
|
Notice: this is an exploit, tools used: IDA Pro and API Monitor v2.
|
|
|
|
## Getting started
|
|
|
|
Download and install ParsecVDD:
|
|
- https://builds.parsec.app/vdd/parsec-vdd-0.38.0.0.exe
|
|
|
|
Use this interface GUID to get device handle.
|
|
```cpp
|
|
const GUID PARSEC_VDD_DEVINTERFACE = \
|
|
{ 0x00b41627, 0x04c4, 0x429e, { 0xa2, 0x6e, 0x02, 0x65, 0xcf, 0x50, 0xc8, 0xfa } };
|
|
|
|
HANDLE device = OpenDeviceHandle(PARSEC_VDD_DEVINTERFACE);
|
|
```
|
|
|
|
- Try this function to create `OpenDeviceHandle(GUID)`: https://github.com/fufesou/RustDeskIddDriver/blob/fc152f4282cc167b0bb32aa12c97c90788f32c3d/RustDeskIddApp/IddController.c#L722
|
|
- Or hard code 😀 with this file path `\\?\root#display#%(DISPLAY_INDEX)#{00b41627-04c4-429e-a26e-0265cf50c8fa}`
|
|
|
|
Let's create a virtual monitor.
|
|
```cpp
|
|
void CreateMonitor(HANDLE device) {
|
|
uint8_t InBuffer[32]{};
|
|
int OutBuffer;
|
|
DWORD NumberOfBytesTransferred = 0;
|
|
OVERLAPPED Overlapped{};
|
|
|
|
Overlapped.hEvent = CreateEventW(0, 0, 0, 0);
|
|
DeviceIoControl(device, 0x22E004, InBuffer, sizeof(InBuffer), &OutBuffer, sizeof(OutBuffer), 0, &Overlapped);
|
|
GetOverlappedResult(device, &Overlapped, &NumberOfBytesTransferred, 1);
|
|
if (Overlapped.hEvent) CloseHandle(Overlapped.hEvent);
|
|
}
|
|
```
|
|
|
|
Call this update function to keep up the refresh rate.
|
|
|
|
```cpp
|
|
void UpdateMonitor() {
|
|
uint8_t InBuffer[32];
|
|
DWORD NumberOfBytesTransferred = 0;
|
|
OVERLAPPED Overlapped{};
|
|
|
|
Overlapped.hEvent = CreateEventW(0, 0, 0, 0);
|
|
DeviceIoControl(device, 0x0022A00, InBuffer, sizeof(InBuffer), 0, 0, 0, &Overlapped);
|
|
GetOverlappedResult(device, &Overlapped, &NumberOfBytesTransferred, 1);
|
|
if (Overlapped.hEvent) CloseHandle(Overlapped.hEvent);
|
|
}
|
|
|
|
long ticks = getTick(); // milliseconds
|
|
while (!done) {
|
|
Sleep(64);
|
|
if (getTick() - ticks > 200) {
|
|
UpdateMonitor();
|
|
ticks = getTicks();
|
|
}
|
|
}
|
|
```
|
|
|
|
Finally, close the device handle to destroy monitor:
|
|
|
|
```cpp
|
|
CloseHandle(device);
|
|
```
|
|
