| # Parsec VDD Specs | ||
|
|
||
| This document provides detailed specifications for the Parsec Virtual Display | ||
| Driver (VDD). It includes information about the preset display modes, adapter, | ||
| monitor and common usage scenarios. | ||
|
|
||
| ## Preset display modes | ||
|
|
||
| All of the following display modes are set by driver default. | ||

||
| Notes: | ||
|
|
||
| - Default display mode is 1920 x 1080 @ 60 Hz. | ||
| - All resolutions are compatible with 60 Hz. | ||
| - Low GPU such as GTX 1650 may get bugged when streaming in DCI 4K. | ||
|

||
| ## Driver implementation | ||
|
|
||
| - Type: user mode | ||
| - IddCx version: 1.4 or 1.5 | ||
| - IO control codes: | ||
|
|
||
| ```c | ||
| // add monitor | ||
| CTL_CODE(FILE_DEVICE_UNKNOWN, 0x800 + 1, METHOD_BUFFERED, FILE_READ_ACCESS | FILE_WRITE_ACCESS) | ||
| // remove monitor | ||
| CTL_CODE(FILE_DEVICE_UNKNOWN, 0x800 + 2, METHOD_BUFFERED, FILE_WRITE_ACCESS) | ||
| // update timing | ||
| CTL_CODE(FILE_DEVICE_UNKNOWN, 0x800 + 3, METHOD_BUFFERED, FILE_WRITE_ACCESS) | ||
| // query version | ||
| CTL_CODE(FILE_DEVICE_UNKNOWN, 0x800 + 4, METHOD_BUFFERED, FILE_READ_ACCESS | FILE_WRITE_ACCESS) | ||
| // set preferred adapter LUID | ||
| CTL_CODE(FILE_DEVICE_UNKNOWN, 0x800 + 5, METHOD_BUFFERED, FILE_WRITE_ACCESS) | ||
| ``` | ||
