3.5 Buttons and indicator LED explanation. 

 

 

Power up: 

When applying power to the viewer, the controller for the LCD starts up checks the 
input EDID data on the HDMI connector. When it is correct it will show video on the 
LCD. The bleu LED blinks fast and if the signal is correct, the green LED turns to 
stable green. If the HDMI signal does not match this inside display or the signal is 
temporally wrong, the bleu LED blinks slowly. 
 

Restart button: 

When pressing the restart button, the inside display controller restarts like power up.  
Pressing this button also switches the resolution on some display controllers. After 
each press, wait for 5 seconds to let the controller and the source (computer) to 
switch over (automatically). If one of them is not able to adapt to that resolution, the 
bleu LED blinks slowly.  
 

Brightness button: 

Pressing this button at the rear of the viewer changes the brightness of the backlight 
of the LCD in 5 steps. The brightness level is stored after setting. When power is 
turned on or connected again, the latest brightness level is restored. 
 
To preserve the lifecycle of the LCD screen, it is good not to set the brightness of the 
LCD to maximum. Keep it to about 75%
