Default Problem with System display

Hi,

When my PC boots the display appear very fuzy and unreadable but when you
uninstall the display driver and restart the PC it becomes readable but I'm
not able to change the screen resolution. Whenever I try changing the
resolution screen goes fuzy and unreadable again. It can only be made
readable again by uninstalling the display driver and restarting the PC. Can
anyone help me by telling how to resolve this problem?

Default Problem with System display

This is a compatibility issue between the video drivers and the display.
The "at boot" display resolution is usually something like 640x480 with a
refresh rate of 60hz.
This is what the default BIOS usually sets. When windows starts, it usually
changes this to another resolution during the startup process.

Windows default drivers usually try for 800x600 or more. Some of the
Monitors and LCD displays use different refresh rates, or different sync
signals to select specific refresh rates and "modes".

In short, the video driver you are using is not well suited to your display.
In past versions of windows, it was sometimes possible to modify an ".inf"
file to correct the situation. Since the .inf file may not be used by an XP
video driver, this may not be a usable method to solve your problem.

All is not lost if you have a common display and video card, since a generic
driver may be available already within windows. You neglected to mention
what video driver was being loaded, the video card make model, and the
display make & model.
Windows automatic detection may not work properly with some displays, or the
display may not reply properly to windows. (Long story, involves digital
data and flow through the video interface between the display and windows.)

The last time I had this type of problem was with an SVG LCD display. (Low
cost, older model)
Prior to that, we might see a similar issue now and then with a few older
analog CRT displays.
