The FDTI driver was not working when connection between PME and BenQ display failed. How to fix it?
Please follow below steps to fix the FDTI driver issue:
(1) Download PME (Palette Master Element) that fits the OS on your PC/NB from local BenQ website.
(2) Remove all USB devices such as Wacom from the monitor, except the FTDI device and USB cable that connects to the PC/NB.
(3) If the FTDI driver still does not work, unplug the FTDI device and then replug.
(4) Reboot the PC/NB and start using PME to check if the FTDI driver works.
Note that if two monitors are used simultaneously, ensure the extended mode, instead of mirror display mode, on your PC/NB is used to display the content on the monitors.
If the issue still exists, please contact BenQ local service center.
