How much backlight bleed is acceptable?

My new laptop has a bit of backlight bleed, visible when the display is on full brightness with a black background in a dark-ish room. Is some backlight bleed inevitable for LCDs?

That's typical of IPS unfortunately.

 

As strange as it sounds, that's actually good news as far as I'm concerned. I was hating the fact that it might be a rare fault and I would have to RMA and be without this laptop for a few weeks. Now that I know that it is a common occurrence, it gives me more peace of mind, as I know a replacement unit would likely have the same issue. Helps me justify keeping it and not sending it back, which I really didn't want to do. Does that make sense?

Also, it's only really noticeable on a black background at higher brightness levels in a dimly-lit environment, so the reality is I probably won't notice it all that often anyway.

 

That's really a subjective question; and really depends on your content: white/bright vs low light/night scenes. As far as I'm concerned, not much.

The Dell UltraSharp seems to have come up with a method to mitigate that nefarious backlight -- or at least a way of dispersing it to make it a lot less noticeable.

At first I was hesitant when I first bought my monitor considering all the negative reviews and all. However, I was pleasantly surprised that the level of backlight is quite muted. And virtually unnoticeable unless you're up on the screen holding a magnifying glass.

On my laptop its not handled as well, but still roughly 10% of what you have (i.e. that bleed on the upper left). If I had a choice, I'd say that's unacceptable.

 

The camera picked up on stuff the human eye can't detect. Only the bleed at the bottom edge is noticeable to my eyes.

As I suspected. A lot has to do with angle and reflection while taking the photo. Those small bleed areas around the edge are the generally acceptable minimum.

 

I can tell you mine has about the same in upper left, it's sad but true.

 

That is just the camera angle picking up extra bleed that is not visible to my naked eyes. The noticeable part that I can actually see clearly are the two small splodges at the bottom edge of the screen.
