I have a Vaio VPCZ13V9E and had to install dual boot as I required Windows 2008 Server R2 in order to run multiple simulatneous Hyper-V virtual images. The only graphics that I can get on my 2008 partition are Standard VGA and the maximum resolution is a very poor, and headache inducing 1024 x 768. The most comfortable resolution is 800 x 600 which is no use at all.
Unfortunately none of the display drivers from the Sony support site work and I have had no luck with all of the nvidia ones. I even called nvidia who said that the graphics drivers in this laptop are hybrid and they do not provide drivers for them. I also contacted Sony support who said that they only provided Win 7 and XP drivers for this machine. I don't see why the Win 7 64 bit drivers don't work! When I install them I reboot and the screen is black with random colours - the machine then powers off and I have to reboot into safe mode and uninstall.
Because I have no recognised graphics driver I also can't even connect to an external monitor via HDMI or the standard monitor output.
Any ideas anyone?
