Hi, I have a Dell U4919 and I've just noticed what looks like a crack with backlight bleeding through it. There's no difference to the feel, so it's not the surface of the screen that's cracked, but there's definitely something wrong. The picture makes it look much worse than it is. It only shows on blacks and isn't really noticeable under everyday use, especially as I have my taskbar on the bottom of my screen. I'm not really bothered about this as it stands because it really is tiny and not noticeable 95% of the time but it has made me nervous. The most important question is: is it likely to get worse? Any idea what caused it? I really baby my stuff. Is there anything I need to do to 'manage' this? Can I fix it at all? Thanks in advance!
