The Menu option on my monitor no longer works. Worse, whenever I need to use the monitor I have to first reset it by connecting it to my laptop otherwise the power light just blinks. Once I have reset the monitor using my laptop everything works okay for several hours. Any suggestions to fix the problem will be greatly appreciated. P.S. If I shut off the laptop and turn the laptop back on the monitor won't work again with the laptop but once connected to the PC it somehow resets.
