libmonitor
===========

This crate aims to be a unified solution to interacting with display devices. It provides a `Monitor` class that can be used to set or read settings of a Monitor.

## Supported Operations:
- Read/Set Contrast
- Read/Set Brightness
- Read/Set On Screen Display Language
- Read/Set Monitor Input Source

## Lower Level Access

`libmonitor` also enables lower level access to the monitor communication bus. Per default type safe abstractions are used, but custom messages can also be sent and received.

## Supported DDC/CI Operations
- [x] Read Capabilities
- [x] Set/Read VcpValue
- [ ] Read Timing Report
- [ ] Set/Read VcpTable

## OS Support
- [x] Linux
- [ ] Windows
- [ ] MacOS
