+# ddc-control
+
+`ddc-control` is a simple utility to get / set display's VCP parameters via DDC (Data Display Channel). It runs on GNU/Linux and Windows. Big thanks to @arcnmx for providing the necessary rust libraries that made it possible.
+
+Usage:
+
+```bash
+$ ./ddc-control -m <monitor_number> get-vcp <vcp_feature_number>
+$ ./ddc-control -m <monitor_number> set-vcp <vcp_feature_number> <value>
+```
+
+Example:
+
+```bash
+$ ./ddc-control -m 1 set-vcp 0x60 0x0F # Set monitor input to DisplayPort
+```
