HP ProBook 4420s display problems Tags: Graphics Cards Hewlett Packard Probook Graphics Displays Last response: January 13, 2012 8:52 AM in Graphics & Displays Share bssehra January 13, 2012 8:47:50 AM Hi I am using a HP ProBook 4420s and having problems with the display. On power up the display is shaded by a green/yellow overscreen which eventually disappears when operational. And from last few days its now showing up at all (Does shows somtimes though). Just a grey/black lighted background. The display is perfect when used with my LED TV as the monitor via HDMI port. Any help/ideas what's wrong with it?
