May I know if its glowing at the spots that you think there is a lot more light as you were suggesting?

Hi,

The spot is not visible in ANY COLOR background but only with White & Few Shades of Grey....

I'm not interested in challenging any one if this is technology flaw and are there with almost all Screens.

To my best this Dell S2216H is using LG Panels...
 
AFAIK back light bleeding happens only along the edges right? Correct me if I'm wrong... This should not cause some pixels in the center of the screen appear brighter...

back light bleeding happens only on the edges and sides as it uses led array on the edges to light the display , and it is a IPS flaw , i have a PG279Q which i bought for 74k and even this monitor has the backlight bleeding and i havent gone for a replacement yet, if it gets worser after a year or so i may go for a replacement

@ryanrulez4ever @Lord Nemesis .. so the issue, what I'm facing, is IPS Technologies Shortfall and are there with 90% monitors than are you suggesting me to close the matter (and to change this Thread Title)?

More like a LCD technology issue. Unlike CRTs which technically work just like a florescent tube light and can produce light by themselves, LCD's don't produce enough light by themselves to make the picture visible. So to make the picture visible, they put a light source (back light) behind the panel. This is usually a CCFL or in case LED Monitors a LED based light source. Have you ever seen a a florescent lamp throw a uniform light across all areas of a room? What if you hang a curtain in front of the light and see from the other side, Do you think you would get uniform light across the curtain considering that the curtain too is not likely to have uniform opacity.

Backlight bleed is usually on the edges, but sometimes can be in other areas of the screen as well. backlight bleed is not limited to IPS displays.

There is one more IPS specific problem namely the IPS glow. Usually IPS glow will not be constant and will change as you move your head or change direction.

You can do it if you like but you cannot be sure that the replaced one will not have any bleed/glow at all. Refurbished or new doesn't matter here. My monitor had excessive bleeding on one set of diagonal corners, I pressed for replacement and fair enough, they sent me a new one. It was worse so I asked for another replacement. They sent another new one and that too was equal to the second one in terms of the bleeding issue. I thanked the RMA guy and told him to take back both the new replacements. I originally planned to return the first but was told I wouldn't be given a refund and would instead receive a CN for the said amount; their policy. I decided to keep the original one and live with it. Sure enough, I got used to it with time. Monitor in question is an Asus PA238Q.

So do you suggest that this issue will be there with any or new (if Dell offer me) IPS monitor also... and there is no need to go with all hassle (to get it replaced) and keep the existing monitor?

Thanks

As I said before, extent of back light bleed on each unit is a lottery. Depends on your luck. You might get a unit with better or worse back light bleed if you replace which why I suggest that if its not so bad and you can live with your current unit, don't replace. Push your luck for a replacement only if your current unit is so bad that you have slim chance of getting something much worse.
 
It does look like backlight bleed. Try reducing it by reducing contrast and brightness. Sometimes it can go away if you load the proper icc profile which came with the monitor. Or just try the generic SRGB ICC profile. This may look silly to some people, but ICC profiles have gamma and other values recorded in them for those particular models of monitors to give calibrated output on screen.
 
Color profiles don't help with issues like these that change from unit to unit. Adjusting brightness and contrast does help a bit.

Yes, I did same adjustment via 'Dell Display Manager' Utility and manage to bring the issue a low lever.

Issue is near to minimal if you keep brightness 100% but this setting STRAIN EYES lots...

I was used f.lux for first 2-3 days but it give me yellowish feel (like reading ancient book), so uninstall it.

Thanks for suggestion

Actually, that is the exact purpose. To filter out that blue-white light that messes up with your eyes. Just turn it on whenever you're working/reading on your monitor and switch it off when watching movies etc. I do the same and have got used to it now. Keep a 4200K temperature even during daytime now.
