I know about the pnp driver. I call it the picture in picture driver because it actually acts as one. I know the pnp driver forces the "desktop to have refresh issues and set a lower resolution for your desktop environment. If you uninstall the driver and reboot it will fix a few things. I know its kind of scary to think about uninstalling the driver. If you are scared to do it just hit disable to test it. I would definitely check for the lg driver even if it is an older version install it. Maybe in the box you got a cd or something that has the driver on it. If the pnp driver says Microsoft driver it is 100% the wrong driver because that is not lg.
