Desktop Display gone Barrel shaped

  Wak 16:59 01 Dec 2006

Hi, Running Win 98SE (which I still prefer) with an AOC 17" 7VlR monitor.
When booting up, the initial screen displays are rectangular (as they should be) but when it reaches the Desk Top it suddenly changes to being barrel shaped and remains so.
I've checked/replaced the drivers for the monitor and SIS 630/730 display (which is built-in to the M/B) but it makes no difference.
The M/Board battery has also been replaced as a precaution.
Apart from being the shape of a barrel, the screen appears to be normal in colour, brightness and contrast.
The fan and the inside of the base unit have been cleaned and dusted out.
As the monitor is just over 4 years old, is it on it's way out?? Or has anyone any other explanation, please??

Can you adjust using your monitor settings?

You need to go into the screen's settings menu and make the necessary adjustments to the display.

This type of calibration display can help:

Thank you for the replies.
I have a few sites in Favourites relating to colour, contrast and brightness. All are to my satisfaction and haven't changed at all.
It's definitely the shape of the picture that's the problem just as if some magnetic field on the CRT is collapsing at the sides.
I can adjust the shape using the monitor control buttons. Adjusting the pin-cushion control has widened the top of the picture but the bottom corners are still bending inwards.
The Degauss control has no effect either.
I don't think monitor controls are the answer as it started going barrel shaped intermittently a couple of days ago, that is why I changed the M/B battery.
Any further suggestions please??
Maybe a new monitor for Xmas???

Hi, Stuartli, I appreciate the Festive sentiment but it doesn't solve the current problem.
There's a thought!!! Is it an intermittent wiring or connection problem??
I think I'll disconnect all the wiring, re-assemble and try to keep the low voltage wiring away from the mains voltage.
Now closing down. I'll let you know the results A.S.A.P.

fould this ,worth a try
You select the On Screen Display, choose the zoom function. Hold down on ZOOM. The OSD will disappear, replaced seconds later with an advanced OSD which you can tidy up the corners pins etc.
or try the RECALL function which should take your monitor back to factory settings.
If those do not work it sounds much like ya monitors
givin up...

Thanks Santos7. In the meantime I've tightened a few connections and jiggled a few wires and, Lo! and behold, it's gone back to normal so will try your suggestions if/when the problem returns.
Will leave things alone for now and tick as resolved (fingers crossed!)

Although the problem seems to have been cured, this comment doesn't necessarily apply to every brand of monitor...:-)
