Screen Burn

Louisa_Jane_2

I have a 19" Dell Flat Screen monitor which I has a patch of screen burn (I think that's what it's called!) It is only noticable on a dark background. Is this something that can be fixed/repaced under warranty as it's only 10 months old.

Some say LCD monitors cannot experience burn-in while others say it does happen....

Anyway, try this (from click here):

MYTH 4: LCD monitors can burn-in:

Impossible! The process by which an LCD display creates images is to change the position of individual liquid crystals in each pixel and block or pass light through them. There is no high-voltage, high-energy discharge; the liquid crystals rotate into different alignments as the low voltages in each cell change.

However, each pixel behaves like a capacitor, and a residual charge can build up inside that tiny capacitor if the pixel remains in the same state for a long time. As a result, the stored charge locks the liquid crystals into one position, even after the monitor is turned off. A quick flash to an all-white screen followed by a black screen clears this residual charge and solves the problem.

If no joy with above, switching off the monitor for 48 hours could cure it (from click here):

TFT-LCD monitors are subject to screen burn-in (image retention). Consequently, you should never keep a still image on your screen for extended periods of time. If you must keep your monitor on, use a screen saver. If you can, set your monitor to drop into standby or suspend mode after twenty or thirty minutes of non-use.

If you do see image retention on your screen, unplug the monitor for 48 hours. This usually corrects the problem.

Also see this.

If you still have a problem despite trying all the above, contact Dell to see what they have to say.

Good luck , G

There are a whole bunch of monitor tests/exercisers on this webpage. I got the Monitors Matter Checkscreen utility some years ago (when it was hosted elsewhere), and find it useful to give solid colours on the screen...
