In order to set or change the resolution of your
Nio display you must be
logged in using an account with administrator privileges.
1. To set the resolution of your
Nio display(s) right click on the
desktop and select “Properties”.
2. Select the “Settings” tab.
3. Select the rectangle that represents the first
Nio display attached
to the BarcoMed

slightly visible on the screen
• This phenomenon, called “image
sticking” is normal if the same
image has been on the screen for a

same image content is not
recommended. Switching on DPMS
on display and PC and activating a
good screen saver may decrease the
risk of image sticking (image
retention).
• A slight case of image sticking can
be solved by continuously displaying
a full white image during a number
of hours.
On a dual-head system, the
images on the left and right dis-
play seem to be switched
• Switch the video cables at the
display controller or at the display
video inputs
