Hello!

I just bought a LG L1933TR-SF monitor. The quick specs are:

19 inch - 1280X1024
3000:1 Contrast DFC (I am not sure what the true is, around 1000)
2ms G to G

When I first got it, the monitor looked beautiful. However, later that day I noticed that there was a bright spot in the bottom right hand corner. It wasn't bad enough for return, but it did bother me.
The next day, though, I noticed it was gone for a while but came back later that day again.
On the third day, it was gone again and has been gone for the last few days. So, what do you guys think, has the montor just 'burned in', or does this have a good chance of recurring? What causes light spots in LCDs anyway? Especially non-permanent ones like this?

Thanks in advance!

(Now all I need is a 2900XT and my comp will be awesome again!)

Sorry, I didn't mean burn in as in the way CRTs did (an image physically burned on the screen.) I meant, do they take a while to begin working properly, do they vary in displayed image while they are new, or will my problem possibly recur (is my monitor possibly defective)?

Actually, some sort-of do. Google "LCD image persistence"

I think the correct expression you are looking for is "break-in" (aka car engines that need a break-in period)

Break-in's probably better in this example however a CPU, for example, has a so-called burn-in period. Maybe you need to burn in a panel before you can over-clock (overdrive) it, lol

CRTs have problems with strong magnetic fields (like when the speakers are too close to the screen) but i never heard of LCDs reacting to magnetic fields. dont see why not. could be a backlighting issue? cheers

Yes, LCDs do suffer from image retention, which is the most widely used term in the industry. Some also refer to it as image sticking and also temporary image persistence.
LCDs for the most part are correctable, unlike that of CRT and Plasma displays. Image retention has improved greatly over the last two years. It has been more easily seen with VA/MVA technologies. Most of the TN panels shipping today rarely show this problem, unless it's from a cheapo panel supplier. But then TN panels are cheapo panels to begin with...but that's another subject.
The severity differs between panels (same part#), panel suppliers, and panel technologies. There are two general ways to get rid of it, both of which take time. Suppliers can't agree on which method is the best. Most widely used method is just to use full white screen pattern at max contrast and max brightness for double the amount of time it took to burn-in image. The other method is a flashing fast on/off full screen white/black patterns for double amount of time it took to burn-in image.
Most of the big monitor companies should have some kind of write-up on image retention on their websites, including even Dell and HP.
I think HP still has a utility that helps with this issue with a pretty good white paper that comes with it. Look up 'LCD First-Aid' on HP website.
NEC Displays website has the best whitepapers hands down though:

Enjoy.

"... how long does it take to burn in an image on an LCD panel? I'm asking for a ballpark figure, of course (days, months...).

May not occur at all, may take days/weeks? I got a new monitor and it warned "not to leave a stagnant image more than 12 hours".
