There's no denying the fact that Dell's 2005FPW is breaking ground as a widescreen LCD display. I think the vast majority of PC Gamers using widescreen monitors are using it.
Why? Why else? Price! When Dell has a special, the price of the 2005FPW often drops nearly 40%! And even when there is no sale going on, the 2005FPW is usually cheaper than most monitors with similar specifications. You can see for yourself by browsing through our Widescreen Monitor Database (here's the 20" section).
There are very few manufacturers making a 1680x1050 LCD screen - LG.Philips is the main one, providing screens for Dell, Apple, and others. So this information could apply to anyone with a monitor using this screen. In fact, this could apply to EVERYONE with an LCD monitor.
The Problem
The problem with "LCD Image Burn-in" is exhibited below. This is my very own monitor. Here is a picture of a corner of my screen, where I keep a browser window and Winamp open:
Everything looks fine, until you shuffle windows around. Here is the exact same section of the screen, with one of the programs moved over to cover the browser and Winamp windows:
It looks almost as if the window has alpha blending applied to it! I assure you that this is not the case. What you are seeing here is not actually burn-in - LCD monitors are technically incapable of such a thing. Instead, this can be called "image persistence" and is actually somewhat common with LCD screens. It seems to be very common with the Dell 2005FPW.
Is my monitor broken?
Unlike "Screen Burn" exhibited by some plasma displays, image persistence is not permanent. It is caused by the LCD crystals becoming "over-charged" from being left in one position for too long. The longer you leave your screen on, the more likely this is going to happen. Obviously, if you can't turn your monitor on, you can't use it!
So what do I do?
The fastest way to remedy this is to only have the monitor turned on when you need it. Always make sure to enable Power Saving Mode in your OS, and set it to kick in at a reasonable about of time - 10-15 minutes. This way, whenever you stop using your monitor for more than 15 minutes, the crystals are "resting" and will be less likely to "stick"
Similarly, you could use a screensaver (after all, this is exactly what they are for!) but it's probably better just to led the crystals "rest" whenever they can.
Having a desktop background can also add to the problem. It won't be as noticable as say, a "Close Window" button like I've shown above, but when a desktop background image burns in, it gives all other windows a distorted, "sloppy" look. So change your background often, or don't use one at all.
If you have an image that is really stubborn, for instance it is there even after leaving your monitor on overnight, try leaving the monitor off for several days. After all, your monitor needs a break, so that means you probably do too!
So don't worry if you see some image persistence being exhibited on your monitor - this is normal! Some monitors may be more prone to it than others, and if this sort of thing bothers you, you may want to keep that in mind when shopping. If you have a widescreen monitor that has image persistence problems, leave a comment in the Widescreen Monitors Database!
