How to save the setting of brightness?

Since our portable monitor doesn’t contain a built-in battery, it does not have a memory function, so the brightness setting of the display cannot be saved, which means you need to reset the brightness every time you turn on the display. The action of setting the brightness is easy, just simply slide the brightness adjustment wheel will be OK.

Why the brightness and contrast cannot be adjusted?

The brightness and contrast cannot be adjusted if HDR is turned on, or ECO is set to “MOVIE, GAME, TEXT.. mode, or DCR is turned on. Please refer to Page 12 to reset these settings.
