4. Adjusting the brightness

Model 1A:


Adjusting/Lowering the brightness 


The display has been pre-set to a brightness level of 100%. 

The power drawn when the brightness level is at 100% may be not be enough for some USB ports. You can reduce the brightness level so that the monitor can operate by a lower power.

If you increase the angle of placement of the controller to a more upright position, we have found that brightness is satisfactory when set to about 70%. 

You can change the brightness level using a small screwdriver to reach the two buttons from the slit on the left side of the controller or unscrew the bottom cover of the controller and adjust with your finger, as described on the next page.

Screen Buttons



Display Controls


To change the display settings including the brightness you need to use the side buttons. (also easily accessible if you unscrew the bottom cover)


The yellow arrows point to push buttons


The silver upper button is a power switch


The lower control is both a push and up/down button and can be used to enter and control the display options


Display Options


When you push the lower button, you will see the display options on screen. 

Push a second time to enter a section and push a third time to select the parameter. 

Move the lower button up/down to change the value of the selected parameter


Alternatively, for Windows, Twinkle Tray lets you easily manage the brightness levels of multiple monitors: https://twinkletray.com/



Model 1A+/Model 2A


On Model 1A+ and Model 2A a remote control is being shipped with the controller which can be used to control the screen's settings
