Monitor issues

[crabcake]

Alright ... help me look smart! A difficult feat, I know!

Monday, I noticed a slight twitch/ripple action in my monitor at work. After checking the obvious (plugs) and rebooting a time or too, it continued AND got worse (and gave me a raging headached). Tuesday, still going on. I call IT, they come up, bring a new monitor to see if mine's going bad. That one does it too. First thoughts were some sort of magnetic interference causing the problem. They replace the video card in my PC. Still happening. Go home with a raging headache AGAIN from the eye strain. So today, I took my laptop from home in, b/c I'll be damned if I get another headache from that crap.

So with my laptop there, I notice there's no twitching going on, eliminating the issue of some sort of interference (unless it's cuz my laptop screen doesn't have the magnetic thing that most standard desktops do). So we hook my laptop up to the regular monitor and violo -- no twitching/rippling on the monitor.

So my next guess is that it's a CPU issue ... power supply maybe? :shrug: Any thoughts? The IT guys are baffled.

How close is the computer to your monitor? I've seen CD players, cassette players and other assorted electronic items do this same thing, just because they are TOO close to the monitor. I want to say I've seen an alarm clock sitting on someones monitor do the same thing, but not really sure I'm remembering that right.. Lights.. THAT was the big one ... we had those cubicles that had the flourescent lights built into them.. one sat right over where the monitor was, drove the monitor crazy when you turned it on.

Also, make sure you don't have a metal filing cabinet with magnets on it too close to your computer. The magnets can mess up the PC monitor.

Have you had a metal plate put into your head recently?

Yes she has, but not recently.

 

[fishn guy]

Do you have receptacles on your desk top?

 

[crabcake]

All of the above issues (with the exception of the metal plate) have been checked and 'cleared' of responsibility. The metal plate was removed a few months back.

And no, I don't have any "discreet toys" causing vibrations to make the monitor image 'shiver' either, as a PM I received suggested.

I'm thinking perhaps it's the power supply in the CPU. :shrug:

I'm thinking perhaps it's the power supply in the CPU. :shrug:

I'm thinking this too, but here's something else, maybe - could the refresh rate have gotten reset to 60Hz (or anything below 70Hz)?

I think this is what the issue is as well. Change the refresh rate, just right click on the desktop and hit properties. Then from there go to advance properties and it should be somewhere in there. Probably under the monitor tab.

As for it being a power supply in the cpu, I would like to see someone fit a power supply in a cpu. Sounds like quite a feat to me. I think you mean power supply for the computer.

Quite the stickler there aint ya? Many ppl refer as the "computer" or "box" or "pc" or "tower" or "desktop" as a cpu...

I don't know. Your laptop wasn't doing it, but that's a plasma screet and not a crt so that completely different. I'd definatly check the refresh rate thne look at the power supply. Did they check the outlet the monitor is plugged into for proper voltage? Do you have a light on your desk nearby? Probably checked that already. It might just be a noisy input signal, I'd change the whole computer.

Well, there are those people who never se sunlight who are much more intimate with pc components.

True...maybe she should replace the fan.. or is that called the rapid air induction/exhaust device?

 

[waupaca]

I would check refresh rate . This is set on CPU. Normal rate is 65hz, but another setting may work better.

You didn't happen to have your cell sitting on the desk near the monitor did you?

 

[mainman]

My nextel does this too, but only when it is gettting ready to ring, bleep or if I am actually on it...

 

[crabcake]

refresh rate was adjusted -- no help. Nextel phone not an issue either.

I just got in and notice the guy came by and put a new cable on it too; still doing it.



I'm thinking it's something to do with the PERSONAL COMPUTER/PC/COMPUTER/BOX/TOWER.

Gonna have to be, ya swapped everything else.

Without seeing the flickering it is hard to figure out what could be causing the problem. If it is still happening after a complete tower and monitor swap you are probably getting hit with EMI. I’ve seen cubicle desks that have the under cabinet lights above the monitor cause problems like this when the bulb or starter for the fluorescent light was acting up. It could be something from a wall if you are set up close to one and the building folk have been working on the power. You might try plugging the monitor into a different outlet too.
