I got my L220x the other day and have been extremely impressed with it overall. However, based on reviews and pictures, the backlight is supposed to be almost completely uniform, but I found that the two top corners have visible bleed. Of course I've seen much worse, but I guess I was expecting even better and don't like seeing the corners when I'm watching movies. In everyday work I don't notice it at all, but bleed is my pet peeve....
Would you say that this is acceptable, or is it something Lenovo would take care of under warranty? Or: am I being overly picky given the price point?

welcome to the forum!
i've seen $2000, $3000, and $5000 displays with worse bleed than that (albeit in different ways depending on the technology).
if it isn't noticeable under normal use then i wouldn't let it bother you, especially if your L220x has good color and is without any dead/stuck pixels.

Thanks. I think you're probably right -- I don't really want to risk getting dead pixels or worse bleed. This is pretty minimal and, like I said, I don't notice it at all during everyday use. Just when I watch widescreen video in the black strip above.
So, I'll keep it.

Unfortunately, I've decided that I will need to get this fixed. When I first turn the monitor on there is almost no bleed at all, but then it gets progressively worse as the monitor heats up. the 'bleed' happens at the hotest spots in the corners -- and when I put my hand there, very lightly, it leaves an imprint . Maybe the backlight is somehow pushing against the panel? Does that even make sense technologically?
So will try to call lenovo tomorrow to see what they say. I've just moved to the UK and lenovo support hours here are pretty terrible: 9am to 6pm. I guess they simply don't want people calling about problems!

First let me say that I still love this display for my daily work: color, brightness, viewing angles, ergonomics and adjustability. It's all good. But as soon as I use it for watching film, those ugly corners become very visible and distracting. I have a question for those in the know and was hoping somebody could give advice here:
I've had many displays and they've all had varying degrees of bleed, mostly around the edges. With the L220x the bleed looks different - it's at the hottest/warmest areas in the corners, where I assume the backlights must be, and I'm wondering if the corner spots might be a result of improper assembly inside? Could it be that some screws were tightened too much and that somehow something is pressing against the display from behind? I found that there is absolutely no bleed whatsoever until after those areas are hot after about 30 minutes of use, and from there it goes downhill in terms of their visibility. My ignorant logic tells me that it's the heat that is causing the problem and that the heat is due to proximity to something -- but I really don't understand that technology so maybe somebody can explain if this could be the case?
Just wondering if perhaps there is a simple solution to this? A loosening of a screw inside to reduce pressure or something....
Thanks for any input!

As you may remember, I've been disappointed with the corner backlight bleed of my l220x and find it quite distracting when watching movies, or any other situation when the screen is black at the top - such as full screen mode in certain applications or really any movie when there is a dark scene. Look bad.
Before I bought this display I read several reviews,yours among them, and everybody seemed to be in agreement that the display didn't have bright spots and that it was generally extremely uniform in illumination and had almost no bleed. that was one of the reasons I got it -- I hate white clouds/spots and uneven backlights.
My question is if you have noticed the issue I am having, i.e. brights areas in the upper two corners that radiate down in toward the middle? Your review didn't mention it, but perhaps you've noticed it after longer use?
I got a replacement and this one is unfortunately the same. I've used other good quality displays in the past that didn't have this kind of issue and feel that this can't be the standard for this display. Hope I'm right!

i merged your threads to keep from splintering this discussion.
unfortunately i sold my L220x back in september and upgraded to a 30" NEC 3090WQXi, otherwise i'd take photos of my display to show its bleed. i don't remember the L220x being that bad but must admit that it's been a long time since i've looked at one.
fwiw, even high-end NEC and eizo displays will show bleed given a completely black background in an unlit room. my NEC has a weird flare at the top that i can spot given the right conditions. it's a $2000 (USD) display made specifically for graphic design so i hold it to much higher standards than i would an L220x. and, i've seen $5000 eizo displays show worse bleed than my NEC, leaving me to think that it's more a CCFL issue than anything else. LED backlights tend to be more evenly distributed but even they aren't perfect, especially at the edges.
i used the L220x for 10 months and liked it a lot, especially for the price. but, i also didn't expect it to be perfect in every aspect given the price.

Thanks for replying!
I understand what you're saying about perfection and price and normally I don't care too much about slight bleed around the edges, especially when I don't notice it under normal use. But this time I care because I'm using the display for movies more than I usually do and those corners pop out and bother me. I also find edge bleed more acceptable than this kind of concentrated bleed in corners.
Above all, I've gotten the feeling from people's review of this display that it doesn't normally have this kind of issue and so I'm wondering if I just had bad luck with these two units, or if it's present in most of them. Don't really want to keep trying to get a good one if this is a known issue with this model.
So: I love this display during the day and dislike it at night - would like 24-hour love though.

that's understandable. as much as i want my NEC to be perfect 24 hours, it isn't. the unfortunate reality is that computer LCDs simply cannot replace a proper television. eizo supposedly has this ability on some of their displays but they cost as much as buying both a TV and a monitor.
i wish i still had access to an L220x or that my photographic memory would trigger. i do remember backlight bleed but don't remember anything specifically in the corners.
