Dell U2412M

I guess I got lucky, I decided to pick one of these up on Saturday.

It shipped on Tuesday and arrived on Thursday easily the fastest 7 day shipping I've ever had.

Anyway I figured people might wanna see some more backlight bleed photos so here's mine.

My new U2412M (its perfect in my opinion, no dead pixels and as far as I'm concerned no backlight bleed):

For comparison here is my old LG L227WTG-PF:

Both taken with a point and shoot on auto, ISO 320 no tripod.

Haven't had much time to game on it yet but in the hour or so I have I didn't notice any ghosting or input lag.

This is easily the best monitor I've ever owned.

If anyone has any requests for pics I'll try and take some, I only have a point and shoot though.

Wow, after seeing your picture I am definitely exchanging mine. Hopefully I just got a rare bad panel rather than you got a rare good panel :).

The upper-right corner looks worse in the picture than in person. It's not noticable in typical use. But the lower-right is horrible. I can notice it when playing full-screen games in normal room lighting.

Give it a few days to settle, take another picture with the same settings and from the same location and see how it goes, and see if it visibly improves in your eyes. The good part is, you won't get a refurb back from Dell right now, so a new one can fix your ills :)

Good luck!

That looks great!

Unfortunately, my U2412M suffers from some heavy IPS Glow on the right upper-corner and right bottom-corner (both up to 9 cm into the screen, diagonally, I tested on an all black screen), when sitting in front of it, even when I'm sitting about 90 cm away from it. It has to be IPS Glow, right? Because the glow dissapears, when I move my head to the corners. Backlight Bleed is always static right? (sorry, but I don't have pictures)

I'm really not sure what to do... Can I get a replacement from Dell, because of the IPS Glow or should I keep this one, because I might get one that's worse?

If it wasn't for the IPS glow, this monitor would be perfect. There are no dead pixels and no backlight bleeding. I've played all sort of some games and there is absolutely NO GHOSTING. I really love this monitor..

That sounds like IPS glow. Even if you had EvilShortys perfect looking display from the photo you would likely see the same thing in real life that you do now. Sounds like you are more sensitive to it and/or like to sit in a dark room with the brightness cranked up which will obviously make it worse. I doubt an exchange will help.

EvilShorty likely took his picture for some distance back (eliminates glow) and didn't overexpose as much as most people do. So you really can't compare pictures from different people all that well.

But Mike1's image with a very bright corner hotspot definitely looks like a physical defect, maybe even shipping damage, I don't think that one will clear up in time.

Actually, I sit in a very small dimly lit room with the brightness level only on 35.(I'm using 10e's settings, which are great, by the way) The glow only bothers me in dark games/gamescenes. Other than that, I love my U2412M. It's great.

So you think, I should keep this one, because most people, including EvilShorty, will have this much glow from about 90 cm(3 feet) away, when sitting in front of their U2412M? I guess EvilShorty's picture must have been taken from 2 or 3 meters away.


@10e : Could you please give me your opinion/advice, a lot of people here, including Snowdog, are very knowledgeable, but you seem to be a real professional and I would appreciate your opinion.

Since you glow is uneven, you might try an exchange... I just wouldn't get my hopes up.
 
If all you have is IPS-Glow I personally wouldn't exchange it. You may get back one with some bleed.

I know, it's a hard decision to make...

Do you have a U2412M and if so, do you have a comparable amount of IPS Glow, when compared to mine?

Heh professional. I'm just a dumb shmo who loves screens a little too much. Or a lot too much, but thanks GL2814.

I usually stare at the display from a number of feet back with a full black screen to see if it's really back light bleed or just IPS glow. IPS glow will disappear here, but BLB will not.

The lower the brightness, the less glow I see, so you can lower it and try a setting of 20 to see if it improves. Try looking at it from 6 feet or a couple of meters to see if the glow is less or not visible. Cameras with really long shutter times (ie. over a second) can amplify non-visible effects. My particular unit will show things realistically between .5 and .8 second shutter with an ISO of 80 to 100, but models vary. If you have a camera with a manual setting try taking a photo with no flash in a dark room from a number of feet away using these above settings and post it, if you'd like.

You can also wait a couple of days for the manufacturing tension to ease and see if it improves. I had a bit of BLB on the top right that looked like a slight haze visible from further away, that is now completely gone, and I have a perfectly uniform black albeit with the IPS glow characteristic of this type of panel.

Let us know how it goes! Good luck!

Thanks 10e, I'll try to post a photo later. One question, do you see about the same amount of white glow that I see, from 90 cm (3 feet) away, when sitting in front of your monitor on an all black screen?

My picture is taken from about 3.5ft away with the camera zoomed in slightly.

I forgot to mention in my first post that I'm using all stock settings (75 brightness 75 contrast).
 
Quick question, does Dell usually charge you taxes based on the full price before discounts? I'm not really sure what the commom practice is, but my last big purchase with a big discount was a tablet price matched at Office Depot with a $100-off coupon from another store and I was only charged taxes on the discount price. ($321 for an ASUS Transformer)

I ask because I went to Dell's Puerto Rico site and to my surprise the U2412M is already (still?) down to $320 there, HOWEVER, when I add two to the cart it's charging me taxes on $800... To top it off the site quotes $110 in shipping for both, yikes! Guess I'll have to chat with a rep to see if that's all right.

$110 in S&H + $56 in taxes has me thinking about just purchasing two HP ZR24w's from J&R at $350 each + $60 to ship both (-$10 discount via code)... $50 less isn't a huge difference but paying Dell that much in tax/shipping bothers me. :eek:

I don't know about Puerto Rico but whenever I've bought anything from Dell Canada, taxes were only charged on the discounted price, not the original price + taxes and then - discount.

That practice sounds like a rebate practice to me, not a discount practice.

Its difficult to get them to look close to real life, they all end up a little washed out or too dark.

I do. First one had too much back light bleed for my liking. The second one, which I just hooked up a few days ago, has a tiny bit, but is much better. They both had ips glow in the corners that went away when you look directly at that area of the screen or backed up far enough. My understanding is that the ips glow is just a side affect of the IPS technology and not something to worry about. I'm not sure how you'd check if IPS glow is uneven since it only comes up when your viewing at a slight angle, which mostly happens in the corners.
 
Just got the 23'' version (U2312HM) of this today and I'm pretty satisfied so far. For those looking for a 16:9 IPS version that are still on the fence I say go for it.

One thing I've noticed with the 3 Dell monitors I've owned so far I hear random popping sounds during operation and after I turn off the display. It appears to have no effect on the output of the displays. I assume it's heat related- like expanding components, chemical related burnoff or even capacitors? Not too familiar with monitor internals, but have been curious about it for awhile.

1 of 2 of my Samsung TNs did this. Is this common in anyone else's experience with Dell displays? I assume since all 3 have done it that it's nothing to be concerned about and may just go away with time.

Thanks for the info, that'll help me with deciding wether to keep this monitor or exchange it.

@10e : I'm sorry, but I can't post a photo, because I really SUCK at making good pictures, actually I have no photography experience at all:eek:

What I can say, is that when I compare your photo to my screen at the same distance (2 feet) and under the same conditions (except that my brightness is at 35), is that my screen has an extreme amount of IPS glow in the right corners (up to 9 centimeters into the screen).

Really, when I look at your screen, photographed from ONLY 2 feet away. Your screen looks perfect on that photo. If my screen looked like that with a black background, I would be very satisfied. I also looked at my screen from about 9 feet away and then the glow was almost as good as gone. But sitting 9 feet from my monitor is not very comfortable, you know.;)

I really have some thinking to do. Keep it or exchange it...
 
Hi all,

Well, I called Dell (not easy to get to the right place with no service tag #, which they don't give for a mere 24" monitor), but finally got there. They said they'd do advance replacement, no problem, no charge to me even for return ship. Well, the replacement arrived today, and at first blush (to my inexpert appraisal), it looks GOOD! They did fail to include a pre-paid return shipping tag, but they've promised to e-mail one.

Anyway, I see no stuck pixels, and the colors look FINE to me. No gray/yellow cast to the white as on the first unit. To put it briefly, at least at this point, I could not be more pleased. I think the last unit had been physically damaged to the face of the screen, causing the blue/purple 'blotch' of which I posted a photo on picasa (link in my last post). Today, looking at that turned-off, blank screen at an angle in light, I could see a slight mark on the screen in the pattern of the 'blotch' I spoke of in my last post.

I will attempt to attach a photo of the black screen on this second unit in a pitch dark room (if I can figure out that process). I see one white dot in the pic, but it was not on the screen -- I conclude it is an anomaly in the photo. Fair amount of IPS glow (not detectable in the pic, and not objectionable to me in my use), but little if any discernable backlight bleed.

The 24" 1920x1200 is a good size for me. Lots of real estate, and things are a good size for my aging eyes. I think I'm going to like this monitor for a LONG time.

Go for it!

Thanks for the help/suggestions, and 73,

My 2007WFP pops and it's about 5 or 6 years old now and still working :). I also had a 2707WFP for a while that would pop really loud. I also assumed it was heat based, as it only happened after the monitor had been on for a bit of time.
 
Okay, so I just conducted my own photo test :)

Perhaps 10e will approve?

Camera Used: Canon SX200 IS P&S
Settings: Manual, Optical Zoom, ISO 80, F4.5, AWB, Evaluative Metering
Exposure Time: Various (see below)

Condition:
Dark room, no ambient lighting.
Camera mounted on tripod, IS turned off.
2-second timed shutter release to avoid "hands-on-tripod" vibration.
Monitor-Tripod Distance: 8-10 feet or 2-3 meters.
Monitor-Camera Lens Height: Same/level

Test Web Page Used: www.doihaveadeadpixel.com (black)

Here are the results at various exposure times:

0.5 seconds

Yeah holzmann, it's quite good. You don't need my approval, you KNOW it's good :)
 
Hello guys, I have NEC 2070NX s-ips 4:3 monitor and am strongly considering this Dell. I have noticed on some photos, especially those from @10e that ips glow is now pretty grey instead of blue/purple tint?
@10e Is it in real same as in your photo where you compare with nec? Can more people who have this monitor confirm? My old NEC have this ugly blue-purple tint glow which I hate but this grey on Dell I see on the photos would be very fine to me.
 
Well I hadn't thought my old Acer X233W was lacking...nor did I know what a lagom test was until I stumbled across this post. Based on the overall positive reviews I jumped on the $329 special a few weeks ago and besides some minor bleed which I'm hoping will diminish with a few days use, I must say I'm more than happy with my purchase. Borderlands looks quite dreamy but the jump in resolution means time to troll the GPU forums :) Thanks to all for the early reviews and info

It's more grey/silver now. I have a Dell 2005FPW that is similar to your NEC, except it is 16:10, but being S-IPS it has the lavender/purple tint so I know what you speak of. It's definitely different.

I definitely don't have that on any of my screens including the U2412M. Can you check that your video cards are showing 59 or 60hz in the video card properties/video card control panel?

http://www.youtube.com/watch?v=aQjXAhC2GQo

I thought it was the media player, but I ruled that out when I figured out I could do it by dragging any window. I then used both Displayport and VGA cables and the behavior was similar, but not identical. With the displayport cable, the image was shifted in a "band" about 2" tall. With the VGA it's shifted in only one spot.

I tried the monitor on another computer and it did something similar, but along the entire height of the screen.

I have no idea how to research this since I don't know what it's called. Is my monitor or computer at fault?

edit: Nevermind, it was my computer. I restarted and it went away....

Does anyone know what this is called either way?

looks like some kind of vsync related tearing issue
 
@10e thank you very much, thats indeed great to hear. I was considering samsung PLS but on this same forum I see people reporting BLB issues and more, so I think am going with this one.

3 last important things I would like to know is:

- how "full white" is white? I mean, I visited friend of my who have samsung led tv(46d5000) as PC monitor and I noticed something was strange. Whites were looking white but not so "full" white, as if something in spectrum was missing. Its hard to describe, but when I returned home that evening and turned on my NEC white color was like "truly white" and life-full. I was thinking could it be LED vs CCFL and how it feels in Dell? For example when compare to that NEC of yours @10e?

- monitor seems to have high brightness and must be adjusted to reasonable level like 30-40 in settings. Which turn me into concern of PWM and LED. When calibrated, how is eye strain on this monitor after longer period of reading text? I know its individual but would like to hear opinions from users who have it already as I never had LED monitor before. Although CCFL blink as well it should be much higher frequency and phosphor doesnt turn on/off in 1ms like led. So is there any strain after brightness is lowered(even to 0) and reading text for at least 20-60min or some noticeable blinking? Does light output feel solid(not blinking) after moving head and looking around monitor?

BTW since LED brightness is adjusted by PWM and at any moment its ON its always on its maximum output, isnt that dangerous in long term? Since its like using brightness to 100% which is about 300cd/m2 but human brain dont recognize it in such a short timeframe, cheating him thinking brightness is lower. Can somebody who understand this problematic say anything about it? Can higher light exposure damage eye in longer term only if its recognizable to human brain or always?

- how you compare AG coating with NEC? Is it same? Does it give "dirty" feel? Sparks?

Thanks in advance, this should be all I need to know.

This is no problem. The human eye evaluates the color stimulus altogether. It would be horrible to be forced to achieve a specific spectrum (see Grassmann's third law). As we don't use a display to illuminate samples this isn't necessary (calibrating for example to D65 never means that the display emits the associated spectrum - keep in mind that all spectral information is lost in the colorimetric values).You can achieve your desired withepoint (which should be visual neutral regarding your color matching/ ambient conditions) through the RGB gain controls.

Best regards

Denis

The white glow, that you see in this picture (from bensen's U2412M) at the bottom right, is what I see from a distance of about 80 cm, sitting in front of my screen (and I see the same in the upper-right).

Is this normal IPS Glow and do most people with an e-ips monitor, see this from that distance on black?

If it's common and completely normal for an e-ips screen, then should I just keep this screen and not exchange it?

I'm sorry if I come across annoying, but I just don't know what I should do. ..
 
Thanks Denis regarding that "white" explanation. I was really woried about LED "white" after seeing that samsung tv. Hopefully I also get other 2 questions answered.

@GL2814, if its ips glow then it must disappear as you move your head looking straight on it, if it shows from direct and any angle then its BLB. Its then up to you to give another try or keep it, I would be tempted to change it as some pictures here show amazing dark screen without bleed. As long as its easy to do it where you buy it. It looks more that glow is one on left bottom and right top while right bottom seems like BLB to me.

Can somebody who understand this problematic say anything about it? Can higher light exposure damage eye in longer term only if its recognizable to human brain or always?

- how you compare AG coating with NEC? Is it same? Does it give "dirty" feel? Sparks?

Thanks in advance, this should be all I need to know.

Denis properly answered your first question and I can concur that white seems like full white.

The monitor's brightness regulation is huge going from over 330 cdm/2 whites down to 45 - 50 cdm/2 which is is great, so it's flexible for all lighting conditions. So even if it reaches full brightness almost instantly. No worries there, and I don't see how any damage could occur to the screen or to your eyes.

I also have gamed on it at brightness of like 5 and 10 and no issues with eyestrain during gaming or during general use of reading web pages, documents, etc.... I don't notice any flickering at all at any brightness I've tried.

The AG is pretty good. It is almost identical to my NEC LCD2490WUXi2-BK even though they are different panels and definitely not intrusive like some other monitors with LG panels. The sparkle effect is fairly minimal in my opinion.

@10e :



The white glow, that you see in this picture (from bensen's U2412M) at the bottom right, is what I see from a distance of about 80 cm, sitting in front of my screen (and I see the same in the upper-right).

Is this normal IPS Glow and do most people with an e-ips monitor, see this from that distance on black?

If it's common and completely normal for an e-ips screen, then should I just keep this screen and not exchange it?

I'm sorry if I come across annoying, but I just don't know what I should do. ..

As always look at the monitor displaying a full black screen from as far away as you can and backlight-bleed will stay and intrude from the corners or sides/top/bottom of the screen while the glow will disappear. BLB becomes quite distinct from further away and easy to spot. How much you are willing to tolerate is up to you. I had a little coming from the top right corner and it is seemingly almost 100% gone now. There is still a tiny bit but it is very hard to see.

Good luck!
