SOURCE: how to disassemble a LG LCD monitor

Hi...there,
There are 2 ways to opened it... 1: from the back, removed 4 screws and get a good grip on both open edges and pulled. Need to give it some force to it. 2: The other, it from the front bezel. First laid it face up and placed a piece of cloth or micro-fiber cloth over the screen to prevent smudges or damaged from the 4 knuckles . Then use both 8 fingers to grasp onto to edges of a bezel and lift it up with some force to it. Do the same on other side Good luck!

for what purpose you want the driver for the monitor? generally there are no need to install the monitor driver.

The message says that the monitor doesn't receives signal - which is normal. Since the problem appears only after you plug in the cable in means that the problem is located there - something is wrong with your pc, most likely the video card has died.
