Backlight Bleeding

[Bingy]

Ok i got a LG W2252TQ LCD monitor and recently got a replacement as my first one has some dead pixels. Now I cant remember if my old one had any backlight bleeding at the top of the screen, while a black screen is present, but ive been testing for backlight bleeding on this replacement monitor and i can see at top the there is a thin line were theres a little bit of bleeding. Its jus ta line but doesnt go down or anything. Is this normal or should I get another replacement? Could the thrid be even worse?

Should be fine. Most monitors show a little bit of bleeding at the edges.

Lowering the brightness and contrast can help reduce it.

Post a few close up pictures of your monitor during normal usage with just the desktop wallpaper, a fully expanded window, a black background, and maybe a game or two if you really want to know what I think.

it seems to occur on the very thin frame that your screen/image sits on. If you look at your screen very closely theres like a 2-3mm boarder. Thats were the very minor backlightbleeding happens. Its now day time I cannot notice it.

Does light from every direction effect the apperance of backlight bleeding or is it only light from the back?

It's nothing to worry about.

Without a picture I would say it could be due to a physical gap in between the panel itself and the monitor frame. The backlight is probably shining through the gap.

"I would say it could be due to a physical gap in between the panel itself and the monitor frame."

Is it possible to create the physical gap by handling it? Cause I tryed to take the monitor out of the stand and tryed for 15 mins but coundlt. (you need to people.) Could clinching down on the front/face solid pannels cause this, though I didnt think i never really thouched the top.

Do i need to reinstall the monitor driver since this is a different LG W2252TQ monitor then the one I had a few days back? Cause before there was a option to roll back the driver but now there isnt.

The gap could be due to the manufacturing process. It's impossible to tell without any close up pictures.

I assume you installed the monitor drivers into Windows so should be uninstallable by you. However drivers will not fix backlight issues.

But do i need to reinstall the driver if the monitor is exactly the same but phyicsally different?

All taken at night time, where at daytime its not noticeable

The first pitcure taken of the screen saver, the camera made the bottom look really lighter then it really is. The camera made it look blue when its actaully just black. In real life the bottom is all one colour to the top but only slighty gets a bit lighter evenly. I read that all lcds or TN pannels have a lighter colour at the bottom compared to the top, not related to backlight bleeding.

Are you talking about a Windows driver or a BIOS update for the monitor? If it's a Windows driver then you shouldn't need to re-install if you did not uninstall it.

The bleeding in your pictures are typical for LCD monitors. Try lowering the brightness and contrast to reduce the bleeding.

Thanks.

Question. Do small 15" LCD monitors have less NOTICEABLE backlight bleeding compared to large 22"s? Cause I got a 15" and when all the lights are off and its loading windows xp it bleeds every were. Large patchs top,bottom and sides/more bleeding then actual normal pure black. But playing games and just looking for it while been on the computer you cant tell if its got any backlight light bleeding. And my 22" has the tiniest bleeding at the top, and you would think you wouldnt be able to notice it at all (reading about the 15") been on the PC comapred to the 15" and you can very very slighty.

Generally, the larger the monitor, the higher the chances of backlight bleeding.

However, the quality of the components uses to make the LCD monitor (including the LCD panel itself) also determines the amount of bleeding as well as the construction process itself.

Even products rolling off the same production line can have minor variations on a microscopic level. This is why 22" TN panel rolling off of Samsung's production can show different amounts and level of bleeding.
