Monitor display "shaking" Problem

[Sahrin]

Well, my display (an NEC MS FE791SB) has off and on had this shaking problem. I tried playing around with refresh rates (I'm running at 1280x1024, and previously had it set at the maximum possible refresh rate...thought that might be it) to no avail. It occured to me on several ocasions that it might be a power problem, however I have UPC and presumed this would provide more than the very simple protection I seem to be getting. Right now we have some workers in the house, and I can hear a saw go on and the monitor shakes. First off, is this bad for my monitor? I don't need a broken one. Second, is there something wrong with my UPC (Cyberpower 625AVR)...ie not strong enough for my system (what's listed below on an Antec 400W SmartPower PSU and the monitor are the only things plugged into the battery), or maybe I misinterpereted its feature set and it isn't doing any line scrubbing? Should I be concerned about anything, or just shut up and buy a good line scrubber? (And if that is the case, do you have any recommendations?)

Hi,

A couple of questions/thoughts:

Is your monitor a trinitron type (i.e. has two wires running across the screen)?
How old is it?
Is there any vibration associated with the saw going on?

I was just wondering whether those stabilising wires may have loosened, allowing the wires that they stabilise to shake and so distort the picture?

Clutching at straws really!

I take it you've eliminated the possibility of any new magnetic fields in the vicinity?

Cheers,

Andy

got a fluorescent light right near it; does turning it on cause the shaking? is the monitor's cable wrapped around or tangled with any others?

my dad's 19" trinitron monitor had a similar problem, it would shake uncontrollably after it had been in standby mode, if you would reset the resolution (go down to 1024 and back to 1280) the probelm would be gone till the next standby, I could never figure it out and my dad decided to buy a flat panel and that monitor went to my sister, strange thing though, it hasn't had a problem since. The only reason I could see is either the 2-3 days of unplugged rest did the monitor good, or the different video card, or dumb luck. You could try the unplugged thing if nothing else works for you, or if you have a different video card handy, try switching and see what happens, good luck.

Hey Sahrin I had the exact same problem with my ViewSonic P95f+ and I posted about it in the Video and General Hardware forums. Check the two threads out, it will help

and what solved the problem for me eventually....don't know, it just went away. Maybe because I kinda changed the arrangement of my desk a little. I guess it reduced any electrical interference that might have been causing the problem. But the cause of the problem could be different for you, so just check the threads out.



Screen shaking!?!

Screen shakes!?!

Sounds EMI (Electro Magnetic Interference.) Can be resolved by shielding. Try some grounded copper screen - or - connect your monitor to a line current filter or stabilizer - a UPS could work.
