Hi All, can anyone help me with this problem. I have a Lenovo Edge 91 desktop computer and I want to set up a dual screen using onboard VGA and onboard display port that uses cable display port adapter for dvi connection. The problem is both VGA and DVI (using display port adapter) has a display on bios, post message and welcome screen. But on windows only monitor using VGA connection has the display. The monitor using DVI (display port adapter) has no signal message on screen. I have tested the display adapter is working, not a problem. Please help me with this one. Thank you.

First, check that you have the latest BIOS and video display driver. Use the search engine above right, search on "displayport", there are a number of recent threads with useful information. If then it is still not working, post specific information on your adapter, and what you've tried.
