NOTICE:

→ Name and number of the display depends on the local setup. Look for the ‘DisplayLink

Graphics’-string in the name.

→ For some computers or laptops, it might also be required to re-configure the previous main

display. Select the adaptor of the previous main display from the drop-down menu and

uncheck the ‘extend desktop onto this monitor’ box.

8. Additional information

8.1 setting screen mode

• There are 3 components that define screen mode:

• Resolution: refers to the number of distinct pixels that can be displayed on the screen, both

horizontally and vertically.

• Colour depth: the number of bits used to represent the colour of each pixel (bits per pixel or

bpp). Higher color depth gives a broader range of distinct colors.

• Refresh rate: the number of times the image is drawn in a second (Hz). Higher frequencies

reduce flicker.

• Some monitors advertise their supported modes through the video connector. In this case, the

USB adaptor gets the supported modes from the monitor. If the monitor doesn’t advertise its

supported modes the USB adaptor mode chooses a set of common modes (see table below).
