I recently updated my computer to windows 7 ultimate but the screen resolution won't change from 640x480 and i have a FPD 1930 monitor but it says i'm using Gneric PnP monitor on VGA adapter

JFrank,

Your monitor needs to be a high resolution monitor which supports 1280X1024. If is not then this is why your monitor keeps going back to 640x480. If it is a hi res monitor then you may need to update your drivers. If it is a Windows machines simply click the task bar>>control panel>>enter "Windows Update" in search box then click it and your drivers will be updated

At the bottom of the monitor, there are some buttons. Pushing the right-most button (Auto/Set) will enable the automatic configuration to happen. This will "automatically optimize the monitor's image position, clock, and phase."

Try downloading or installing new drivers for your video card, and the monitor. If you already have the latest monitor drivers for Windows 7, I would recommend updating the video as it's the other reason you might not be able to increase the resolution.

Turn on the PC. Press F8 at booting into windows 7. It will display  many options

 

Select the Enable low resolution video(640x480) then login to system.

then change the resolution as required

Right click on a empty space on the desktop and click on Screen Resolution.

Enable low resolution video (640 × 480)

You need to set your PC video resolution to the native resolution of this mointor: 1280 x 1024 @60Hz

The resolution of teh screen is controlled by the computer, not the monitor.

Find your display settings in whatever operating system you are using. You will be able to change the resolution there. Easiest way would be to do a Google search for "change resolution in XXXXX" where XXXXX is your operating system. (i.e., Windows XP, Windows 7, Mandrake, etc.)

reboot the computer in "safe mode with networking" by rebooting the machine and during the manufactures name screen, tap the F8 key and you will see the muli-boot menu come up. Safe mode usually loads a resolution the video card and monitor agree on. You may have corrupt video drivers that give the black screen. While in safe mode, go online to windows update and let it scan your system, choose custom installation and look for the optional updates, these will be the hardware drivers you need to update your system. Check them all if you like and let windows install them automatically. Once done reboot normally and see if that clears the problem.

Anyways, yes, the native resolution is 1280x800 at 60 Hz. Its a PnP device part of the Mobile Intel 945GM Express chipset family. Find a ATI Mobility Radeon plugin or create one. Be careful, ATI desktop drivers dosn't support offficial mobility chip (some inf entries are missing).
Start with drivers from your manufacturer. You can use ATI desktop driver files, but you have to add your hardware device number. Be aware, that's not a official solution, but this works in most cases.
Thank You

Go to device manager-> expand display adapters. Rightclick on the video adaptor and select properties. Click on driver tab and select option RollBAck driver.
