I just did a Windows 7 clean install from Vista on my Acer 5810TZ (mobile) and although the resolution is set to recommended 1366 x 768, I continously get a notification that "the optimal resolution for this display is 1366 x 768" and should be set as such. I am afraid to uninstall the driver to reinstall but I don't know of any other option. The driver is updated. Also, I'm having trouble with my (D:) drive. Any connection?
