My monitors keep doing this (Dead/glitchy pixels?)

[GamerDaily]

So I'm not sure what's happening here but my monitors keep doing this for no reason? Not sure what to call this and I haven't found anyone else with this problem yet. This is my monitor in the pic & the pixels are broken around the middle and it sucks alot (the edges are fine). When you turn it off, it looks normal but when it's on, the pixels are like this. Does this have to do with the backlight? My other monitor was also like this. Both of them were fine at the start but after awhile both got this exact problem and can't use my monitors properly. These monitors are pretty old though, released a long time ago.

Try using different cables, could be a bad video signal. Also what monitor model are you using?

Your monitor is dying soon. It is time to change a new one. Unless you plan to change the polarizer yourself, don't ask me how, I never try and never intend to try as well.
