Getting started with newrez
First, you will have to download the latest release form either the project’s website (see the homepage link at the end of the article) or via Softpedia, save the archive on your Home directory and uncompress it using any archive manager utility.
Right click on the ‘newrez’ file, go to Preferences, access the Permission tab, and make sure the the ‘Allow executing file as program’ option is checked. Then, simply double click the script to open it.
A dialog will be displayed, showing the current settings, as well as the default resolution of your monitor. You can choose a new horizontal size and the script will automatically adjust the resolution, while keeping the aspect ratio untouched.
