It appears that backlight bleeding is a problem that affects nearly all LCDs available. I know it is *really* bad at the top of my HP w2207. (It's the only problem with that monitor that really bothers me.) I heard someone say that it does decrease as the monitor gets "worn in". Is this true?

Does Backlight Bleeding go away?

I have heard of some uneveness of illumination that can manifest on new computers and then fix itself with use. I think most backlighting probably doesn't get better though on most monitors that have it. My NEC 20wmgx2 didn't have any backlighting issues but my Dell 2007wfp did. The extra $200 was worth it in many ways.

I think the people that claim this just get used to it over time. I don't believe it gets any better (why would it?). I had a samsung 225bw (my friend has it now) and the backlight bleed is pretty much identical to what it was almost a year ago.

Yes, some types of backlight bleed can go away by itself. This is mostly pressure-related backlight bleed. If the front panel is uneven, panel tightened too hard into the bezel etc, then the pressure can cause backlight bleed. This can be an error from manufacturing level, or from transport and storage.
When you use the screen, then heat makes the material expand to some degree. When pressure is releaved, the backlight bleed caused by the pressure can disappear.

I'm considering returning the monitor, but it is undeniably better than the Samsung, so I have not decided yet. (The dithering is not noticable unless you look and the backlight bleeding is better at the bottom and in the centre of the frame, it's only really apparent along the top edge, where it's really bad.)
Unfortunately, the service from South African retail outlets sucks and I'm sure I'll have to wait ages to receive the replacement. Nobody keeps stock of anything here.
That said, I do have seven days (Which takes me to Wednesday) to decide. I'll put it through its paces this weekend.
Some of the feedback to this question has served to confirm my belief that bleeding is caused by shoddy design and bad Q.C. If it's possible to completely seal the back of a film camera, I'm sure its possible to fit the panel in such a way as to solve the bleed problem!
Perhaps a handy tech with a screwdriver could fix it by adjusting the panel to fit the bezel correctly.

I had a 2407WFP which did not have any visible bleeding at first.
A few months later, significant bleeding showed up but would fade away after 20 minutes of use.
Again, a few months later, this issue totally disappeared.
Anyway, I sold this monitor at a good price and bought the HC version!

I had a Dell 2005FPW that had this. Called them and they sent me a replacement with 99% of backlight bleeding gone. They never picked up the old one and didn't ask me to ship it back. It's been over a year, so my roommate is using it now. Oh well. 
Honestly...if you can see backlight bleeding on anything but a blank/black background then you either have the brightness/gamma too high or there is an issue with how the panel is joined to the frame. Like the gentleman that posted the first reply, I have a Dell 2007WFP as well as an NEC 20WMGX2...but the opposite is true for mine. The Dell has no perceptible backlight bleeding and the NEC has a very slight bit at the top center that pretty much went away when I reduced the brightness and contrast to useable levels. As far as it going away over time...I don't see how that's possible if it's a physical issue with how the panel is joined to the bezel. Maybe you just get used to it?
