Running Windows 2000 workstation SP4 on a single card PC.

If I boot with monitor connected, it all works fine.

However, if I boot with no monitor connected, wait for it to boot,
then connected the monitor cable, I get no signal on the monitor.

Weird thing is if I subsequently power off, connect the monitor and
boot it still wont work. Only solution then is to reinstall the
machine.

Its as if the booting with no monitor is knackering things, as if its
switching the machine into a different mode or something.

BTW. I can boot into Safe mode though at all times.

Possibly a bad cable. What are you trying to accomplish?

I suspect that booting without a monitor causes Windows to select a display
mode that is incompatible with your monitor. Re-installing Windows is one
way to resolve the issue, selecting a basic display mode (e.g. 800x600)
while in Safe Mode is another.

Not bad cable. Tried two different monitors with different cables.

Our 'system' consists of a number of machines, with just one monitor
which is plugged into one machine at a time, so we need the machines
to boot ok without monitor attached.

Yes. I was thinking it was something like this too.

Only use 1024x? anyway though.

You don't say what kind of monitor but connecting a crt monitor while
the system is powered used to be considered a no-no. There were a couple
of reasons postulated .... one that the video card needed the monitor
attached to correctly detect the monitor and configure itself
appropriately .... also that connecting the monitor under power could
physically damage the video card and/or monitor.

I don't know whether either of these effects is postulated for LCD monitors.

TFT monitor.

I read what you write but during the past 20 years of working with PCs, I've
never experienced any problems when plugging monitors in or out while the
system is powered up.

I suspect corrupted or missing drivers.
Once in safe mode, go through device manager and check for errors.

Might also be something as simple as a cracked cable.
Also check and make sure the plugs are properly seated.

Yes, I've (unintentionally) done it too without a problem. I usually
avoid it on the general principle that mating/unmating any live
connector is best avoided.

(And bad things can happen. I was a mechanical engineer working on a
communications satellite years ago. We had just completed a bunch of
powered checkout tests and were a bit behind schedule when a technician
pulled a DB-25 connector before the satellite was fully powered down.
The grounded shell of the connector hit one of the connector pins and
blew out the slip rings buried in the geometric centre of the spacecraft!)

In the case of monitors, I'm pretty sure it was the standard warning in
ATI video card manuals at one time. I think it was concerned with
properly detecting the monitor and not, accidentally, getting into an
operating region that would overdrive the monitor circuitry. It's also
going back a few years and the devices may be better protected these days.
