I just purchased an ASUS K53E-B1 Laptop, with a core i5-2400 inside. The graphics are the integrated chipset.
My issue is I want to use my monitor and the laptop screen as a dual screen setup. The monitor is plugged into the HDMI output then I use an HDMI - DVI adaptor which goes to the monitor.
When I boot up Windows the "Splash page" comes up on the Monitor then transfers to the Laptop screen once windows loads. Once in Windows (7, 64bit), I try and use the Intel Graphics Manager and it does not detect the second monitor. I tried installing the latest drivers and the monitor came on and was working as a dual screen setup, but when I reset the computer, as asked by the software, it stopped working again. I reverted back to the 2291 driver and again, it worked perfectly until I reset my computer as prompted.
Clearly there are no hardware issues as everything has worked, but no matter what I do I can not force Windows to recognize the second monitor unless I reinstall the driver and then it only works as long as the computer stays on (not possible with a laptop). Any ideas?
