i don't see that option on the screen resolution page.Hi, under the screen resolution, there's an option in blue writing called "Connect to a Projector" click that and select the option you want, this worked for me.
Its in Blue writing under the drop down menus for "Display", "Resolution" and "Orientation"The drivers were installed automatically. Windows Update shows that there's an update for it but errors when it tries to install. the error occurs when it's already been installed(according to the error description)
i don't see that option on the screen resolution page.
when i tell it to extend the desktop to the second display it errors "Unable to save display settings"
i've tried both the nvidia control panel and windows. still nothing.
Is it possible to use the up to date drivers for vista for the video card?
I think u can use ntune to lower your clock speeds, although from what I can gather you will need to flash your graphics cards bios wuth the new clocks so that it runs at those clocks from the moment you turn it on. you will still get the problem on start up if you dont as ntune wont have loaded the clocks you have chosen yet. You can try using ntune to lower the clocks then changing resolution to see if the problem goes away, but the problem will still remain when you boot up. I think I saw that the core clock needed to go down to 488, Im not sure about the memory clock. I also saw that overclocking sometimes fixed the problem.Thanks for the info! I am using an eVGA 7900GT, and no I have not used Vista prior to Windows 7. I think I would like to change the clock to factory speed. Do you have anything you can point me to? I will see about the 158.24 driver if I cant get the clock sorted. Thanks!
Does the the same thing happen when you change resolution? I could use one monitor on its own and it would be fine except when I changed resolution. Im not sure what you could try, maybe even older drivers, or try clocking your card to what has been said here before.I am having the same problem with the blue and white lines, it looks like corrupted drivers, however it only works when I choose "extend display" I can use both displays fine individually, or cloned, but not as an extended desktop.
I am using an XFX Nvidia 7900GT, and have tried both the newest drivers and the 158.24 suggested. My card is not over clocked.
If anyone can offer any additional assistance it would be very helpful!
