# SetDPI

This is a sample and simple C++ console project to change windows Scale and Layout aka DPI scaling from command line parameters. It can work on single and multi-monitor setup.

## How to use

It takes up to 2 parameters, first being the scale in percent. The second argument is the monitor index, which you get from windows display settings, if you click identify it shows you the index.

`SetDPI.exe [DPI scale value] [monitor index]`

If you have only one monitor or want only main monitor to change you can omit the monitor index.

To get the current scale of a monitor, replace the scale argument with `get` to print the current scaling. For automation with `value` only the scale is printed.

## Examples

- To set 2nd monitor to a scale value of 250
	- `SetDPI.exe 250 2`
- To set main monitor to a scale value of 125
	- `SetDPI.exe 125`
- To get the scale of the 2nd monitor
	- `SetDPI.exe get 2` prints `Current Resolution: 250`
	- `SetDPI.exe value 2` prints `250`
