Dirty, jumpy monitor


Recommended Posts

I've got a new monitor, a Viewsonic 95f 19". The display occasionally shudders vertically, as if it's got goose bumps :o The shelf it's on isn't shaking or anything.

Also, the display is quite dirty in places. The dirt isn't on the outer screen which I can just wipe off - it's more of a burnt look around the edges and corners.

Anyone any ideas on how to remove either of these problems? I'm not to pleased about this happening with a brand new ?420 monitor!

I dont know if its smart but I had problems like that. kinda shady in the corners and was all dim.

You can open up the monitor and youll find a few things you can turn, each one does a different thing, turn them till you fix it :)

I brought 3 19" monitors like 3 months ago, all of them werent as sharp as my 5yrold acer monitor.. and the dirt look your talking about, i had them on both the monitors and my 3rd 19" monitor has it but not as bad.. im thinking it has to do with video card.. what video card do u have?

my monitor (PF790) has a setting called purity which, if adjusted can remove the brown/purple corners. I accidentally loaded my subwoofer next to my monitor in my jeep while moving and created a "dirty" spot on teh corner and used purity to remove it. Hope that helps

The purity control helps, but it's at 100 and can't go higher with the marks still there. The video card is a Gainward GF4 Ti4600.

Another thing I notice is that the positioning of the screen at a given resolution changes each time the resolution changes - it's kind of annoying to have to adjust the positioning so often, although it is slight each time.

Degaussing, degaussing, degauuuuuuusing.

Sadly, if the built-in degausser won't fix it, you may have to take it to a service center, where they can manually degauss it.

i bought a monitor from circuit city a couple months ago and it shook after it was on for a while, so i took it back but they didn't have anymore of the same monitor so i got a neat wide screen sony monitor ;)

Lol Hunter .. some computer's really don't deserve their owners.

I do have speakers beside the monitor but they are shielded. I've moved them away anyway and it hasn't helped.

After the damage has been done, moving the speakers away wont cure anything! Personally I bought a LG Studioworks 19" 995SU over a year ago and it is absolutly amazing! It was one of the cheapest ones I could find (?220) and I have no problems whatsoever! It has a four port USB hub built in aswell and it is a short depth model which is nice when trying to save desk space!

Are you serious? i though once u move speakers away again.. it fixes up.. hmm :dead:

Nope, degauss is meant to "fix" casual EMF disturbances, not prolonged exposure to one. It could fade away over time, but I doubt it. Once the damage is done, it's irreversible.

Also check to see if you don't have any strong static magnetic fields near the screen (unshielded speakers, magnets...)

Add Microwaves to that too.... I had a monitor once against a wall, and the microwave on the other side of the wall made the screen "shiver" until it turned off.

Then it might explain why my monitor is kinda brown.. or getting to it slowly.. i got speakers and amp on the floor... i thought the speakers and amp wouldnt get to my monitor :o

I wonder if monitor warranty do replace.. hmm :devious:

i had always thought the speakers, if not magnetically shielded, would only damage the monitor permanently if the exposure was prolonged. i assumed this, i guess cuz as a lil dumbass, i had tried to see if a piece of magnet would stick on the tv. nope, just cause a green shade to center around the place where the magnet was. :( of course, i attribute it to my inquisitive nature. :D i would've never learned of it, had i not done that.

anyway, the green shade disappeared within a week. phew. boy, was my dad angry for that week though. :dead:

"magnetically shielded" is usually an included feature in speakers for the pc. as manufacturers realize that otherwise damage may result to pc components.

i'm not sure on what exactly is done to shield a speaker as such, but it isn't the soft covering on speakers. magnetic fields can go through that.

if your speakers are for computers, they should be magnetically shielded. don't know about the subwoofer though. Hunter's story leads me to think that it isn't. but i've got a subwoofer under the table and a 17" crt on top of the table (less than 1 foot away) and the monitor is fine (it uses the trinitron grill).

i've never tried non-pc speakers on pc's and won't even allow it near my pc. don't want that magnet incident to bork my hardware.

1 meter seems far enough, but I believe, as the sound level increases so does the magnetic field. Could be wrong though. Didn't really get into speakers during Physics. :D

I'm guessing you've already tried degaussing. Try to move other electronic sources away from the monitors. Power adaptors and such may contribute to those problems too.

Any Dimmer Switches for lights close by? that may sound weird, but I have had problems with regular TV's getting interfeirence from a dimmer switch being turned down a bit.

Also, try moving the monitor around and see if the discolored areas on the monitor move to other areas of the screen, as I have noticed that problem on my TV too, due to the Megnetic Pole, which is what a Deguass is for, unfortunitely my TV doesn't have one.

As for monitors, I've never had any interferences, even with speakers or microwaves near it.
