ScreenFocus is described as 'Working on multiple screens? Getting distracted by side monitors brightening somewhere in your peripheral vision? That’s why we created ScreenFocus'. There are five alternatives to ScreenFocus for Windows, Mac and Linux. The best alternative is Monitorian, which is both free and Open Source. Other great apps like ScreenFocus are Dimmer (Free), PangoBright (Free), Iris (Freemium) and EasyOnTheEyes (Free).
Monitorian is a desktop tool to adjust the brightness of multiple monitors with ease. Remarks The monitor name shown in main window can be changed for easier identification of monitors. To change the name, press and hold it until it turns to be editable.
