"shadow" on my new lcd monitor

hi,

lg 204wt-sf



this happens only on the left side, visible only on medium-intensity colors (almost unnoticeable on white and black, and even on the standard windows widgets "light gray" ). it goes continously from the top to the bottom.

*maybe* on the right side the foremost pixels are a little too bright, maybe.

what could it be?
lamp? crystal matrix?


do you suggest to exchange it with another 204wt-sf?
this one has no dead or hot pixels, i'm a bit concerned about swapping it... the vendors of course do not allow me to test them before buying

thank you

Mura problem typically seen with TN panels. In this particular case it would be called V-mura.
This type of mura is usually seen at top 1-inch of screen across top.
Known issue with LPL panels seen with 19+ sizes.
Panel supplier process control issue.
A lot of the time V-mura (banding) will show up in the center of the screen. Monitor suppliers are supposed to screen for this but sometimes it's overlooked. Everyone is in a rush these days.
No guarantee it will get any better with new monitor/panel.
Insist on checking it first. Use full gray(med dark) pattern.
Good Luck.

thank you guys for the very informative replies

so if i understand correctly it's a panel problem....

the med-gey uniform pattern reveals the shadow quite well, but it's not dramatic.

using a pattern made of stripes


the shadow is definitely there, but i think i can live with it, especially if there are worse alternatives...

Sorry, not correctable.

LCD Monitor Shadow Effect

This problem is best described as the LCD monitor "Shadow Effect".
The solution to this very simple. No software or hard ware changes required.
The cables that are connected to the LCD monitors are causing the problem. Its also called as electromagnetic noise or electrical noise.
Solution: Keep the two cables - (power cable and moitor display cable), that are connected to the LCD monitor as far away as possible with each other and also away from other electrical cables.

Thats it. Your shadow effect is fixed.

Thank you.

Thank you very much too Anonymous user!! You've just solved my long-standing problem, I was getting crazy, I tried all sort of settings on the display and on the operating system...but nothing ever solved or changed...
Actually, the power and vga cable used to be very closed, but now that I've put them a bit farther away...the problema has been magically solved!! No more shadows on my lcd screen!

Thanks a million!
