Hi!

Is there such a thing as backlight bleeding in the middle of the screen?

I recently bought a Philips 244E1SB monitor and there seems to be something that looks like backlight bleeding but it is not on the sides, it look like some sort of line that goes from top to bottom almost in the middle of the screen.

I always though backlight bleeding was on the sides, can it also be in the middle of the screen?

I did some research and it looks like it might be something else called mura...

I initially though this could be some sort of reflection from elsewhere in the room but it doesn't seem to be...

Any ideas?

Thanks!

Nick

Backlight bleeding is usually not a line but a region. Is it a sharp line? Mura is described as flashlighting or clouding, and should not be a problem on newer displays. Could you have a vertical line of stuck pixels?

I said a line but I should have said that's it's a region of the screen that starts from the bottom of the screen and goes up to the middle of the screen. I said a line because it's relatively straight and well confined on the screen.

On a black background it's relatively noticeable to the human eye but it's probably not pronounced enough to be picked up by a camera.

I paid extra to have coverage for dead pixels (and other screen defects I believe) but if it's too common a problem I'm not sure it's worth it to get it replaced just to end up with a replacement screen with the same problem... My other monitors have some backlight bleeding but it's confined to the edges so it's not as noticeable...

I am attaching to this message a picture that shows which area is affected (this is a drawing as I don't think a camera would be able to pick it up, it's so pale it looks like a reflection from something else in the room...)

Thank you very much for your help!

Nick

Sounds like whatever it is, you should take it back. Mura is caused by a manufacturing defect and cannot be fixed short of replacing the panel.

Thank, I'll send it back (it comes from BC (NCIX))...

Let's hope the RMA guy will not be as much a pain as last time...

Thank you and have a nice day!
