Could you please specify what do you refer with the display driver? Are you referring to the driver of the LED TV that you installed recently or you refer to the graphics controller driver?
In addition, if the problem started after connecting the new TV, and if the system still works fine when using another type of display monitor, the issue might be related to the new TV that is being connected.
Also, specify that is the version of the driver that you have installed for the video controller and let us know if this is happening with the driver on our web site or if this happens also with the driver provided by Asus*. Keep in mind that we provide generic drivers, while your motherboard manufacturer provides customized drivers for the motherboard they designed.
