Viewsonic monitor shake?

[Lairans]

I dont know if this is something anyone else has ever experienced before, but I am having some wierd issues with my g90f Viewsonic monitor. I have always loved Viewsonic monitors, this is the first issue I have ever had with one. It seems like no matter what refresh rate I set, there is a small shake in the upper right hand corner of the screen. Its not extremely obvious so I thought that it was nothing at first, however, I have started to get kinda sick staring at it for long periods of time. At 100hz refresh its the least obvious, but it is still noticeable. It just gets worse and worse untill the whole screen looks to have a slight shake at 60hz. This is at all resolutions.

Things I have tried:

1) unplugging all electronic devices near the computer (speakers etc)
2) swapping video cards, I used to use a ti4400, but I recently picked up a 9500 pro and the shake is still there.
3) moving the monitor away from the wall (to rule out some kind of interference)
4) I even called viewsonic and they couldn't suggest anything other than giving me an RMA # to ship it to them.

I was just wondering if you sharp people had any ideas of something I have totally missed before I blow 50 dollars on shipping to send the damn thing to Viewsonic (shipping 19 inch monitors is just not cheap).

Thanks guys

You could try to swap both the power cable and the VGA cable to rule them out. Also plug the monitor into a totally different circuit. Did you degauss it? Give it the thump test? (give your monitor a love tap to see if it responds. Actually works sometimes). No idea what else to try. Hopefully you can come up with something. Good luck.

hey
Two things-are you using a splitter (a/b switch)? Had the same problem with my sony... Also, it could be EMI - I don't know much about the subject so do a google search.. Oh yeah, why not return it to where you purchased it or try to find a local viewsonic support center.. Hmmm.. If it is a defect you should demand that VS send you a shipping label...

I never thought to give it the "thump" test Hrm -- might have to try that. I have never heard of a power cable going "partially bad" (in that it still sends power to the monitor, but has some defect), but I will try that also. The VGA cable isnt really swappable, unless I am just clueless.

About demanding that viewsonic send me a shipping label -- I think that is the problem with me, I am too nice. How would I go about demanding that? They already gave me an RMA number, is there anything in particular that I should say to expidite the process?

I thought about it being EMI, but -- would that be somewhere in my house, or int he wall? I thought I ruled that out when I moved the monitor into the center of my room, but I dont know a thing about EMI other than the basics.

thanks

You may not be able to remove the VGA cable. Depends on the monitor. If you are concerned about EMI, try taking the monitor to another location (someone else home or work) and try it there.

I doled out three of that model at work today. The third one had just what you describe... the whole display was jiggling I figured, "oh, bad monitor" and swapped another one into its place, and then it had the jiggles.

So I said, "weird, bad onboard video maybe? " and plopped an add-in TNT2 Vanta into that system. It jiggled anyway.

So then I said, "hmm, bad... power supply or somethin' " and grabbed an old Pentium2 system and IT JIGGLED TOO. :Q

So I looked around again for sources of magnetic fields, and then it occurred to me to look on the other side of the wall that this monitor was backed up to. Hey, how about that... the electrical mains and circuit-breaker box for this floor of the building

I then put the monitor about six feet from the wall. Call me jiggleBgon, because the display was now steady.

Bottom line, try moving your monitor.

Well I'll be damned.. Moved the monitor about 4 feet from the wall onto a stool and plugged it into laptop. No shake! Absolutely lame! I cant think of ANYTHING that would cause the interference. There is nothing but a 8 inch wall inbetween me and the next room. Is there anything I can use to block the interference other than a piece of lead (lol). I am sort of in a stuck position because moving my monitor would involve a serious rearrangement of the room. Thanks guys

So I was partially right - yay! Anyways, hmmm.. Tough call..MAYBE you could call radioshack or even home depot for some advice? By the way, are your speakers shielded?

 

[knightc2]

Do you have a UPS or a subwoofer nearby that could be causing the interference? Strange...
