After changing brightness by click tray icon,the brightness is reset to 50% when opening the tray icon again.

And the brightness number will never change which is on red line

This picture show that twinkle-tray can't read the current brightness of monitor named VX2478-2.

In short, thank you. This software solves my inconvenience about monitor brightness adjustment。
