Hansol 520F - Manual (Page 7)

The microcontroller automatically detects the video board installed in your
system. When you turn on the monitor, the Micro controller first checks the
display mode memory stored in the user setting area and the factory presetting
area.
The microcontroller has memory capacity to store 24 different display modes
including timing formats and display settings. This memory capacity is
divided into two parts. One is the user setting area, the other is the factory
presetting area.
The user can add nonstandard modes. If you adjust display Image, the image
is saved automatically. Then the microcontroller always detects and displays
the last mode stored in the user setting area when the monitor is turned on.
The user setting area maintains the last 6 display modes set by the user in its
memory. When the user setting area is full(6 modes are registered), if new
nonstandard timing is registered, the oldest timing settings will be deleted.
There are 14 display modes stored in this area. These display modes are preset
at the factory and include most of the display modes currently available(see
Timing Chart of this manual).
You can also retrieve the factory preset mode by selecting the RECALL menu.
The monitor automatically saves the setting value after certain times
(20 sec) of adjusting OSD menu.
