I have just installed Windows 8 Professional edition alongside Windows 7 Professional, however I cannot use my built in monitor when within the normal mode of Windows 8, Instead I have to use an external monitor (I'm currently using my TV via HDMI), however, in safe mode I can use my built in laptop monitor, or if I disable the intel HD 3000 graphics driver, however I do not want to do this because I would prefer to still be able to use my dual-monitor setup, I have all of the latest drivers for the video devices and still no avail, could someone please help!

Thanks in advance,
