A monitor recreates visual signals received from the PC. Therefore, if there is trouble with the PC or the
video card, this can cause the monitor to become blank, have poor coloring, noise, Video mode not
supported, etc. In this case, first check the source of the problem, and then contact a service center or
your dealer.

2. Check if the computer beeps more than 3 times when booting.

3. If you installed a new video card or if you assembled the PC, check if you installed the adapter
(video) driver and the monitor driver.

(Do not exceed 60Hz when using the maximum resolution.)
5. If you have problems in installing the adapter (video) driver, boot the computer in Safe Mode,
remove the Display Adapter at the "Control Panel, System, Device Administrator" and then
reboot the computer to reinstall the adapter (video) driver.
