## About
This project introduces a standalone solution for creating a virtual display with Parsec VDD, without relying on the Parsec app.
This project introduces a standalone solution for creating a virtual display by using [Parsec VDD](https://support.parsec.app/hc/en-us/articles/4422939339789-Overview-Prerequisites-and-Installation), without relying on the [Parsec app](https://parsec.app/).
> "**Parsec VDD** (Virtual Display Driver) is a perfect software driver developed by Parsec. It utilizes the [Idd/cx API](https://learn.microsoft.com/en-us/windows-hardware/drivers/display/indirect-display-driver-model-overview) (Indirect Display Driver) to create a virtual display on a computer. This virtual display is particularly useful in situations where a physical monitor may not be available or when additional screens are desired.
> One of the notable features of Parsec VDD is its support for a wide range of [resolutions and refresh rates](#supported-resolutions), including up to 240 Hz. This makes it well-suited for gaming, as it can provide a high-quality visual experience. It enables users to simulate the presence of additional screens or work without a physical monitor, enhancing flexibility and customization in display management."
How does it compare to other IDDs? There are many open source repos, but you could not get signed drivers and perfect gaming solution.

There was an [usbmmidd_v2](https://www.amyuni.com/forum/viewtopic.php?t=3030), but it seems useful for a simple virtual display with limited resolutions and refresh rates.
