Color monitor 19T2
Error handling
Should an error occur, first check the following points. If the distortion is still not eliminated, the
monitor should, if possible, be checked on another PC.
Self-diagnosis
The monitor is equipped with a self-diagnosis function. If the monitor recognizes a fault, the screen
display remains dark and the power indicator glows green or flashes orange.
The power indicator glows green


Switch the connected PC off.


Press and hold down the button on the front of the monitor for 2 seconds.
If all four color bars (white, red, green, blue) are shown, the monitor is operating properly. In this
case, check the PC.
If the color bars do not appear, this may be due to a fault in the monitor. Please contact our
customer service center with a description of the problem.

Switch the monitor off and on again.
If the power indicator continues to flash orange, there may be a fault in the monitor. Determine the
