It is a disguisting problem which I am myself facing. This causes due to moisture on the monitor curcuit components and the curcuit pads get pressed. This can only be solved when by replacing rusted parts. Contact a monitor enjineer.
SOURCE: brightness and contrast decreased automatically
check that you were not running any programs that you have allowed to automatically change settings, enter control panel and set settings to allow manual changes only!
