245287 2004-06-17 20:22:00 Thanks guys for all your comments.

Last night I changed the settings in FS to 1024x768x32, but it still looked a bit dodgy....

So I changed it to 1024x768x16 and it looks great, and doesn't make a noise.

To be honest, I haven't a clue about what I've done, but that's a story for another day. I also don't know why the monitor "squeals" if these settings are out of kilter.

In someone wants to explain that in SIMPLE TERMS, then they'll find an eager listener in me, otherwise all's good.

Thanks again
Tim

245288 2004-06-17 22:03:00 The scan frequency signal that result from resolution settings is applied to the "yoke" or deflection coil.

That coil is large, and surrounds the "neck" of the CRT.

The scan signals are a ramping waveform and will naturally cause high frequency "squealing" that is outside human hearing (e.g. 40 kHz)

Some frequency settings (and the scan signals that result) could cause vibrations at a sub-multiple (sub-harmonic) causing resonation of some mechanical part at say, half the frequency. This depends on there being something that will resonate and vibrate at that frequency, and if there is then thats what you are hearing.

Moving the scan frequency (by changing resolution) and the frequency moves away from the natural resonance of the mechanical part. Then you don't hear it.

Its not rocket science, its a vibration.

245289 2004-06-17 22:37:00 Thanks Godfather for that simple, easily understood explanation.

Basically, the thingy wraps around the hoodacky, and shakes it's bootie till the whatchimacallit throws it's toys out of the cot.

Silly me, didn't know it was that simple. : )

As I've fixed it, does that make me a rocket scientist?

Cheers

And when anti-matter is introduced into the sub-multiple stream we get a space-time continuum. ;\

245292 2004-06-18 00:28:00 Damn! I thought we got beer.

Oh well, I'll throw my anti-matter out next rubbish day, and sell my sub-multiple stream on eBay.

245293 2004-06-18 00:36:00 This is the latest way of travelling through space without out the need for all that tedious jumping in and out of hyperspace. The principal of generating finite amounts of improbability are so bloody obvious that I wont go into them here.

Well alright, I’ll go into it a bit. The standard approach was to use say, a Babmblweeny 57 Submesion Brain to an Atomic Vector Plotter submerged in a nice hot cup of tea, and this had long been understood. Such gizmos were used to break the ice at parties by making the underwear of various female guests jump away from the unsuspecting (or possibly suspecting) victims body.

Many respectable physicists were not too chuffed with this usage of the technology and attempted to make a more substantial use of it by developing a drive for a spaceship. These were a real bunch on no-hopers (not normally invited to the types of parties mentioned above) and they ultimately failed.

It was left to a student who reasoned that if such a machine is such an impossibility, then it must logically be a finite improbability (obvious isn’t it!?). So, the student geezer calculated the probability (or improbability) and fed the answer into an improbability generator (that was just lying around), and made a nice cup of hot tea, and turned it on! (not the tea, the generator). Presto!! The infinite Improbability Drive was discovered!

Yep, these Infinite Improbability Drives aren't made, they’re impossibility erm... calculated.

245294 2004-06-18 00:56:00 Agreed, however you left out the beer.

Maybe godfather can explain the whole beer/underwear calculation to ensure that it's works to the required functionality.

I bought the latest Babmblweeny v57.1; but returned it to Microsoft coz my beer tasted like tea.

Apparently the problemr will be fixed by way of a patch.

Am I the only one worried about the beer?

Now THAT is infinitely improbable :)
