Backlight bleed.

[Doctor McNinja]

First of all I should say that monitors have never been the greatest area of interest of mine so I'm not really confident in my knowledge of them. So, please forgive me if some of my terminology is incorrect or I make so kind of noobie mistake.

I've bought a new monitor and as far as I can tell there are no dead or stuck pixels... I'm pretty confident in that conclusion, But, when it comes to judging what is and isn't backlight bleed and what level of bleed is acceptable, I'm not so confident. In a dark room my new IPS LED monitor is still pretty bright. Brighter than my old TN LCD screen but it's uniformly bright. It does seem to be brighter at the corners than in the centre of the screen but that changes depending on the position of my head. If my head is position directly in front of one of the corners then it's just as dark as the centre is when my head is in a central position. Basically the screen changes brightness according to my viewing angle.

There's not even the slightest hint of clouding to my eyes and non of the "corner flares" you see when bleed is particularly bad. So, is it possible to have a uniform level of bleeding across the entire screen?

NOTE: I've tried taking a picture of the screen but my camera makes it appear much, much brighter than it actually is. Ill see whether I can adjust the brightness of the picture to more accurately represent what I see with my own eyes [EDIT] Uploading file now.



Here's the image. Please ignore the very light bands around the monitors bezel. They're a by-product of my inept photoshop skills. The screen still looks a little brighter than it actually is, particularly in the lower right corner.

There will most probably be a certain amount of BLB in any monitor but my guess is what you are seeing is actually IPS glow - common in all monitors of this type.

If you notice it more at "off" angles, in particular looking down on the monitor, it is almost certainly IPS glow

I've just had a quick look on google images and it looks like you're probably right. I just love my new monitor so much that I'd hate for anything to be wrong with it... and as we all know, that's when the paranoia creeps in and you start hearing clicks for you HDD and you swear you can plastic getting a little bit too hot and so on and so on... [EDIT] Until you turn into a nut case like me and leap out of bed at 06:00am thinking your computer is making the most horrendous grinding noise only to realise that it's a.) not switched on and b.) the bin lorry outside your window.


[EDIT] Thanks to both of you.

Yes that is IPS glow with maybe a tiny bit of light bleed at the corners, all modern IPS have this problem due to no TW polarizer.... If you want to get rid of it then try using ambient lighting or a backlight on the screen instead of using in the dark.

Unless the screen is displaying a almost entirely black image in a completely unlit room, then I can't notice any issues... not that I've went out of my way to look for them. So far, the screen has been great but I'll put it through it's paces with a dark game such as AvP later and report back.
