Hi, I have a dell 18.5'' led monitor. Earlier it was working fine but for the past few days it is fluctuating continuously. It is connected to a UPS.  I tried it on the mains but it doesn't switch on. I even installed it's drivers. I don't know whether it's a UPS problem or the monitor problem or the video card problem!!!!!. Plz help me out... thnx...

It sounds like your monitor is on the way out, but it may not be. The simplest way to check is to either plug in a different monitor, just borrow one, or take your monitor round to a friend's house and plug it into their computer.

 

If you plug another monitor into your and it works perfectly, the problem is with your monitor. If you plug your monitor into a different computer and it shows the same faults, it is definitely your monitor. You could also try substituting different power leads and video leads.

 

Why are you runnning a monitor off a UPS ?  Is your local power supply, shall we say, flexible ?  If that is the case, it could be that your UPS is not managing to hold a steady output voltage. Have you tried metering the output voltage ?
