WinXP Safe Mode RefreshRate too high for LCD

prona · Sep 1, 2004, 05:42 PM

I have a 17" Benq FP791 LCD which has a max refreshrate of 75Hz as does most LCD monitors. My problem is that I can't get into safe mode in winxp or vga mode without the monitor saying OUT OF RANGE. They both use 85hz..which is too high for my LCD. Luckily, I have a CRt i can use to plug in and change the refresh rate, but I am going away to college in a few days and I am not lugging the CRt with me. So how am I going to deal with this?? Any solutions?

I think the actual problem is to find out why the monitor is not working
correctly when you try to boot in this manner. A monitor can't know if
you're in normal or safe mode. All it knows is that the signal being sent
to it is not acceptable for the current settings the monitor is using.

You know that the display is fine in normal mode. When restarting, the
monitor complains. We know that, if possible, XP will use the already
installed driver while in Safe Mode (the same one used during Normal mode).
If the already installed driver was being used, there would be no out of range message.

When the already installed driver cannot be used (damaged, missing, won't
load correctly for whatever reason), then a generic driver will be
substituted for safe mode operation. If your normal display settings are
too great for that generic driver, then a message would appear.
To fix the desktop size or, possibly, the refresh rate should be bumped down a notch or two.

Yeah i know that. I'm talking about when i uninstall the display driver to install an upgraded driver. After the reboot, i need to go into safe mode and use DriverCleaner to clean all of the files. But when I go into safe mode, the windows generic driver will be used since I would have already uninstalled using ATI Uninstall. This is when I run into problem with the generic refresh rate being too high for the LCD monitor.

when you boot into safe mode have you tried going into VGA mode as opposed to just safe mode?

also..what kind of video card do you have? as if you have sp1 or newer on an XP machine ati drivers come standard..so this problem shouldn't exist

Maybe Refresh Force ? (dunno if the program's settings load in Safe Mode though)
