MX610 screen burn in?

Hi everyone, I wsa wondering if burn in was normal, and/or covered by the warranty. I purchased a mx610 around mid february. At first it seemed that a couple vertical rows of pixels were darker than the others, but since it was a relatively uniform block, and was only really noticeable when lots of pixels were illuminated (say having the mx610 dispay a music equaliser, or the winamp visualization pugin) I thought nothing of it. At that time I was running it on my old system, however early march I built a new system running windows vista x64, and thus had the unsigned driver problem. So during that time, since I didn't feel like loading unsigned drivers each boot, I left it be, but plugged in. This resulted in it simply displaying the matrix orbital logo for a significant portion of time. Once I learned that signed drivers were out however, much to my dismay upon configuration, I discovered that the pixels which had been illuminated by the logo were now also darker than the rest. Meaning that if I light up all of both lines, you can make out a faint negative version of the logo. given that the pixels it used are now darker than the rest.

I can post pictures if it would be helpful to understand what's going on. My question then becomes, if the lifetime of each pixel supposed to be this short? If so i assume this burnin is normal.. still I would have thought they could last more than a month while retaining their brightness....

If not, would this issue qualify for an rma for a replacement?

Thank you for your time.

Hi SuicideKing,

Thanks for your post.

As you predicted, can you please post a picture of the "burn in" problems you are experiencing? That would be helpful for us.

And no, it is not common for a PLED display to have a "burn in" problem in less than a month.

Thanks!
Clare

Actually it is normal, while a PLED takes over 10.000+ hours to get to its halflife (the point it's half as bright as it originally was) it's a non linear process. it loses about 25% in the first 1000 hours then slowly fade the other 25 % in the next 9000 hours.

The following graph shows the degradation in brightness of a generic pled.

Hi everyone thanks for the answers, I'll try to get pictures up by tonight, just to show what I meant however, I realized that the severity of the problem isn't as bad as I thought, the problem is, the computer is positioned in such a way as to mean I look at the screen from an angle, in which case the dimming is far more noticeable than from looking at it straight on.
