Monitor seizure, (screen expands, goes out, returns to normal).
My 19" seven year old monitor has recently started having the following problem and it is getting progressivly more frequent.
It will be working fine, then.....with a clicking sound, the screen expands and darkens a little. At this point I can still click on objects and move the screen. After about 30 seconds (which seems to be getting longer) the monitor turns off, then immediately turns back on and works normally again, often for the remainder of the day, but just as often it will repeat in the same manner.
When the screen expands I have begun giving the top corner of the monitor a sharp smack with the palm of my hand and this will always made it work OK again. Other than that it's a great working monitor.
Any help or sugestions will be greatly appreciated.
Canslim, when one of the boards heats up inside it fails, the task is then handed to the backup chipset to get you through your session. The monitor is nicely letting you know its time is almost up. You could take it in to have the boards tested to see which one(s) is failing, but that would cost more than a new one.
Probably not much different than you were thinking.
Hope it helped.

That really happens if you've been using the monitor for a couple of years already. There no fix for that but to replace the monitor, I would recommend getting an LCD or LED monitor, those are energy efficient.
Hi, There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed. Let me know if I can assist you any further regarding this. Best wishes, Graemevm
go to NVDIA web site download the latest driver.
you need at least 32bit color to setup the monitor.
the 8-bit color is a default, that is why the monitor alway return to default size which is 800x600.
19" monitor should have minimum of 1280x1024 with 32 color.
don't up the color 256bit. the color will be off on the monitor.
Hopefully there is a cable loose or something like that. Try reseating the cabling. I think it is a monitor problem but it wouldn't hurt to try the monitor on anouther computer. It sounds lke a heat problem in the monitor scanning circuitry. It may be repairable if the picture is still looking good. Youll need a schenmatic and some patience and a soldering iron or a reputable service tech.
To my knowledge, it is not the zoom that has to be adjusted but rather the horizontal width, zoom would expand all (to, bottom & both sides) whereas your only concern are the two sides.
Should the horizontal width not fully expand, then there is an internal problem with the horizontal deflection circuitry which could either be the yoke, a capacitor or shunt diodes. In certain instances, a below normal voltage at the mains or the internal power supply could also cause this.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
It sounds like one of the capacitators inside the monitor is malfunctioning, these little things store a certain amount of necessary power and then discharge it when it is needed. If it is malfunctioning, it could explain why it takes so long to charge, and why when you hit it, it suddenly comes on.
As a quick test I would try connecting the monitor to another PC to make sure the problem follows the monitor. If it does then the likely cause is a circuit board or possibly a poor connection inside the monitor. Since working on this would require opening the monitor case and voiding your 1 year warranty I would recommend you contact Samsung support for a warranty replacement as soon as possible. When you do make sure you mention the problem goes with the monitor and any other troubleshooting steps you have taken.
Also the replacement they send will itself be something that was returned and fixed.The only warranty you will get will be whatever is left of your original year so definitely get this taken care of as soon as possible.
