G450, ViewSonic PF790, and degauss with every restart

[Accipitral]

Hello,

Anyone have an idea about my situation?...here it is:

My ViewSonic monitor's manual explicitly states not to degauss more than once every 20 minutes. That's not a big deal except that I run lots of hardware and software installations, as well as BIOS changes and such, and with every restart, the monitor gets degaussed.

This doesn't happen with NVIDIA cards I have (GeForce2 MX, TNT).

It's a real drag having to worry about damaging the monitor with excessive degaussing.

I'm using the latest BIOS and drivers for my G450 (BIOS 1.3-23; Power desk 6.50.008, display driver 4.12.01.1800). Oh, I'm running Windows ME, too.

I'd appreciate any thoughts on the degaussing ways of this card.

Thanks,

Phillip

Does the monitor degauss everytime it's turned on?

I have a PF790 as second monitor (w/G450) and it makes a nice loud noise when i turn it on..i'm guessing that's degaussing

Hmmmm I have an Optiquest Q71 and it makes that degaussing noise everytime i boot up or restart ive had this thing for 4 years and it still works even did it with the voodoo banshee card i had so just must be the way view sonic wants their monitors to boot up???

Yes, every time the monitor is powered off and on it gets degaussed. The on-off cycle happens with every restart, too, thus my concern with the multiple degauss business during BIOS changes, software installations, etc.

I wouldn't have worried about this had it not been for the monitor's manual's caution against degaussing more than once every 20 minutes.

I have got G400 and PF790. I guess it does degauss, but who cares, I turn computer on in the morning and turn off in the evening. W2K rules

Accipitral, the reason for this warning is because a varistor (ptc) controls the degaussing circuit and cycling power at a rate faster than once per 20 min will cause it to become very hot and thus could possibly burn it out.

Don't sweat it tho... all monitors (and TV's) do this. (regardless of graphics card attached)

Wow....that's very good to know....Thanks, for the information!

Hello folks.
Although changing DPMS settings may help, a <u>well ventilated</u> (Don't need fans, just open space arround it) monitor won't B harmed of excessive degaussing.

4 those of U who don't know what Degaussing really is (& those of U who "think" they know), try this fine article

You guys sound like a couple of basket cases.

Your monitor shouldn't degauss except on power-up of the MONITOR.

The clicks you hear when you boot are the video modes changing (something like 640x400 in bios, then your regular res.)

If you hear that 'grunting like' sound, that's the degauss circuit.

Degaussing only occurs if the power is removed, by unplugging. Simply turning the monitor off will not trigger a deguass. The deguassing circuit is right off of the AC power and isn't affected by any other circuitry in the monitor. Paul is correct you are hearing relays turning on and/or off to activate the different refresh rates.

Actually, the monitor is indeed and in fact powering off and then on again. I get the deguass (noise with screen wavering effect) during that cycle. As for the relays turning on/off during changes in resolution, refresh rates, I never get that at all on this monitor (ViewSonic PF 790). This is the first monitor I've used that stays silent during such changes.

Again, the monitor gets powered off and on during a restart, whether from choosing "Restart" from the Windows Shutdown menu, or from a change in BIOS setting.

I'm running an AMD Thunderbird CPU on an ASUS A7V motherboard. I'm also using Windows ME.

Given what I've read on this thread, I don't need to be overly concerned with the way this monitor does in fact get degaussed (and powered off and on) during my restarts.

Many thanks to all who've responded to my question.

I've grown accustomed to hearing that nice "Click" as the relays turn on and the refresh rate changes. I've been hearing that since my first Mystique and Millennium II.

My wife's Viewsonic PS790 "clicks" as her desktop opens. I just figured it was a Matrox Tradition....LOL
