Monitor keeps moving!

[JayE]

Hi,

My colleague has a monitor display which keeps having "funny turns" - the screen grows outforwards for a few seconds and then goes back to normal size.

Very disconcerting !!!

Is this a monitor fault? or something to do with the video card?

Could be either, or perhaps it is the settings for the video display.

Check them both to make sure they are set properly.

Have any changes been made lately?
Maybe a game or something graphically intensive installed that would have changed the video display settings?

If you provide more detail, such as when it happens,...what you are doing at the time.....anything that has changed it will help us to know what to advise.

If you have another computer available, the fast way to check the monitor is to move it for a while to the other system and see if it still happens. I would do this first if possible. That way you can rule out the monitor or pin it as the cause.

Good Luck! Kimber

Have a 17" Daytek that does that too. screen zooms in and out and won't stay still. Give it a smack and it settles down. Don't know what causes it, but using the old 15" monitor with the computer it works fine.

Usually when this starts the monitor is on its way out.
Good thing you have the old one for backup. Kimber

Hi,

I've swopped out the monitor for another of the same spec, so he's okay.

I can set up the suspect monitor on another PC for testing, but unless I was sitting there all the time I couldn't tell if it was still happening, because it's totally random.

Do you think I should keep the monitor?

Do you have warranty?
Might be worth giving them a call....

If not, it sounds like a minor annoyance. If it were me I would prob use it til it croaks...but that is me...

If you have swapped his monitor and that is the problem, then you have isolated the cause. Not much repairable from a user prospective. Kimber

I have a friend that fixes monitors for a living. He used to work for TTX. He looked at one of mine that was doing that once and told me that it had to do with dust collecting on the horizontal and vertical deflection plates within the CRT itself by means of static electricity. This causes temperature variations in the plates that distort the image. He said that this usually means a CRT replacement which just doesn't justify the cost of the repair.

Thank you for posting back. Members always like to know the end result of a problem.

A lot of monitor repairs are CRT replacement and your friend is absolutely correct, not cost effective for repair.

Sorry it couldn't be better news....but happy you have your friend sorted out.

Cheers!

If it's not under warantee, I would keep it around unless you have a better spare. It never hurts to have a spare monitor around, even if it's not something you'd want to use very much. In a pinch, it's a lot easier to use a computer with a not very good monitor than it is to use one that doesn't work at all.

 

[KimberTech]

For sure smah...
It's also the fastest way to check for a bad video adapter if you have no video at all on a system.

Thought that I had a cmos battery problem, as the time would be off sometimes. Happened again today, but a re-boot fixed it. Not a cmos problem. I noticed that whenever the monitor started acting up, the time quit working until it settled down. This is unheard of and makes no sense to me how this could affect it, but with the old montior re-installed it kept the time just fine.
