Hi,
I just bought a new PC based on a Gigabyte GA-Z87MX-D3H mobo with an Intel i7-4470T CPU. The OS is a clean install of W7 x86 and I have the problem that there is no display on either HDMI or DVI. The display on VGA works fine.
I have determined that if I right-click on the display adaptor driver in the Device Manager and select uninstall followed by install then the DVI output starts to work. However any recourse to Sleep or a reboot causes it to stop working until the procedure is repeated.
For the reasons above I believe the issue is a driver problem but I have tried both the drivers provided by Gigabyte as well as the latest Intel drivers supplied in the file Win32_15319.exe which I downloaded from this website.
Any ideas what I need to do to resolve this problem ?
Many thanks,
Mike Davies
