# xeventbind
[xeventbind][xeventbind] is used to run a script on resolution change.
## Use Cases
xeventbind can be used to:
- Change the X DPI for specific resolutions, useful, for example, if you switch between traditional and HiDPI displays often
You should not use xeventbind if:
- You don't change resolutions often or don't need to run anything on resolution change
[xeventbind]: https://github.com/ritave/xeventbind
