Video problem

>>>I put in an old pci video card and the sides of the display are all concaved inward but no more on and off(although it did do it at first a few times with the older card).

That is called I beleive pincushioning. And can be corrected. Most monitiors have buttons or slilder in the front that you can use to make adjustments to the screen display. Try that. And if the display behaves then the oter video card would seem to be the culprit. Doesn't matter how new it is it could be defective


The Crazy One

I have tried every adjustment on the monitor including pincushioning and it makes no difference. With the 3d card the monitor goes on and off in just about 1 second increments. It doesnt do it with the old card although it did at first. I cant see how a 3d card could send a different signal than the regular card during normal internet use. I wasn't doing anything serious when it started. Also can you explain how the desktop could be off the screen when the monitor is first turned on and with no adjustment it shrinks to fit the screen in about 2 minutes or so. If i shut off the monitor and turn it back on after 20 seconds or so the desktop is huge again and takes a couple minutes to re-shrink. Dont forget it doesn't matter if the desktop is large or small.......the sides are still concaved.

Try your monitor with another PC, if it misbehaves, then it is the problem. If not, then the cards are the culprits.
