ZBar is a simple tool specifically designed for those users who use multiple monitors in their work, because it allows you to manage them all from one simple screen, being able to see what is in each one of them and move from one to another with greater ease.
ZBar is creating a kind of taskbar for each of them, which are housed in the lower part of your monitor, so you only have to access the content of any of these taskbars and access that particular monitor.
A basic but very practical tool so you don't go crazy with so many different monitors.
You can free download ZBar 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
