old monitor on XP/W2K computer

On my working w2k/XP computer I have to temporarily use a CRT monitor from
an old win98 computer.
On booting it shows the OS selection screen and then the Windows XP logo
screen correctly, but when it reached the login screen the screen sort of
duplicates itself horisontally many times and starts blinking.
I set the screen parameters to the lowest possible (800 by 600 and 16 bit) -
the same.
Tried to boot in safe mode - the same. Booting into w2k - the same.
Reconnect my "normal" LCD display - works fine.
It looks like the monitor does not support the videocard or something like
that
Can anything be done?

If not, is it OK to plug-unplug LCD monitor without switching off the
computer?

The computer is in a resolution and/or a refresh rate the monitor can not handle.

Along with what Dave said, yes, as long as the monitor is off, you can
connect/disconnect the monitor without turning off the computer.

Reduce your refresh rate to 70 Hertz or less and that should fix it.

They say that is a bad thing to do. But I have done this for decades and
many times per day and I never had a problem ever.

I personally seen a monitor "fry" itself and the video card when the
plug in was done. It is a pain to fix after.

If it's currently set up to work with the LCD monitor, it ought to
already be set to 70 HZ or less shouldn't it?

I would say use 60 hertz, as everything should work fine at 60. Then if
you want to, try higher rates once you have it working.

I have heard of this before. And very old monitors, I can see this
happening. As the very early ones would fry if you turned them on
without a signal. But since the days of color CGA monitors, I have been
plugging and unplugging monitors while computer and monitor still fired
up.

Later I used a KMV switch. That only lasted a bit. Nowadays I hot swap
the cables again. And since I only use laptops and netbooks, I use my
computer desk with an external monitor, keyboard, and mouse. And I am
hot swapping at least 2 to 3 times a day.

If something ever fried, you bet I would stop doing this practice. But
it has worked for me for decades, so I can't complain. ;-)

Not necessarily. My LCD is running at 1024x768 at 72Hz with no problem, but
my previous CRT at 1024x768 would only run at 70Hz or less. Of course, a CRT
at 60Hz sucks- most of them suffered from "60 cycle hum."

Thank you. It was set to 60, but when I set it to 56 it worked -
thanks again

Hmm... interesting. Is your AC power 220VAC @ 50 hertz?
