Backlit bleed, how much is too much?
 
Hello all. I just got a brand new U2713HM from Dell, from the days of deals.

My only issue with it is the backlit bleed. Given I've never owned a monitor that bled like this before I'm trying to find more info on whether this is worth a RMA or not.

First of all, it bleeds an anoying shade of green or yellow in the bottom left corner and a less aggravating blue in the lower right. This is hard to notice unless the background is black. Room lighting is normal / comparable to daily use.

When Googling backlit bleed issues, I clearly see pictures that are much worse than mine, but I assume these to be the worst cases whereas mine is a less obvious case.

Part of my problem is that some advice I've read say that this is normal and a RMA could yield a worse panel. Did I just pay 600$ to play rainbow lottery? :p I'm a bit puzzled. How much do you feel is acceptable when it comes to this particular issue? Aside from this, the panel has no noticeable defect. Colors are the most vibrant and accurate I've ever seen on an monitor out-of-the-box, and no dead pixels.

Can you try taking a picture of the bleeding and show us? You can always call Dell and see what they'll do for you.

Yes I'll do that. Will wait half an hour or so for the sun to go down though, at this hour there's direct sunlight on my desk only half-filtered by non-opaque blinds, so it wouldn't give a decent picture. I'll upload one in a bit :)

Pitch black room. Brightness about 85% contrast about the same.. take a picture.

Any LCD will have backlight bleeding some worse than others but in general you could get a better one or a worse one.

I waited a little longer than planned to do 'normal activities' first with my new monitor. Ie, watching part of a movie in native resolution and playing some Tomb Raider 2013. Those tests were somewhat reassuring as I had a hard time noticing the bleeds; it's certainly alot less evident than when you're staring at black, anyhow.

Still, here are two pictures - sorry for the rather poor quality, I only have my cellphone here ATM. I took them in the dark at 85% as suggested. You can clearly see the blue and the yellow, or maybe orange. I'm green-yellow colorblind so it's hard to tell, but I sure as hell know it's not black ;)

And a side by side shot with my trusty old wfp2407, which doesn't bleed at all:

If this is 'normal' according to you guys, I'll likely keep things as is. I just need an outside opinion or two to make sure I'm not simply keeping an abnormal panel. I've had only a few monitors, and it's the first one like this, so I'm fully ready to accept it's no big deal - but if it's not normal, given the price tag, I'll get it replaced for sure.

I would say return it. Ultra Sharps should be a lot better than that...

If it was pure white, it would be backlight bleed. This looks to be something else though since it's coloured.

Thanks for the advice. My understanding is that bleed can be coloured or white. I may be wrong, but if I search about the issue, I'm seeing alot of coloured bleeds in stills of all sorts.

The rule is simple with IPS:

If the bleed persists when viewed straight-on from far away, then it's bleed. If it disappears then it's IPS white glow. Your 2407WFP is S-PVA so it won't display this when viewed staight on.

From what I can see, the yellow bleed on the bottom left is high.

Return it.

Thanks, I opened a support ticket with Dell. (edit: and so far, it seems like its going to be a PITA)

Valamyr March 19, 2013 11:00 AM

The tech support finally relented and promised me a replacement within a couple weeks.

Wasn't thrilled about it, though, I had to insist. Said the new one may be as bad / that this panel seems to meet their specs, etc. We'll see.
