Dell UltraSharp U2412M 24-Inch Screen LED-Lit Monitor, Black

Update -- after using a new adapter to connect to my MacBook (VGA to DVI, I believe), the sleep problem seems to be solved! (I did not change the type of adapter, just swapped one adapter for a different one at work.) So the problem seems to have been in the adapter. I am updating from one star to 5 OLD REVIEW FOLLOWS... THE PROBLEM IS NOW SOLVED! I bought this monitor to work with my Macbook Pro, 13-inch, Late 2011 model, running Mac OS X Lion 10.7.4. The monitor works great for a few minutes then goes into energy saver mode, goes black and will not wake up unless I use mirroring mode, which I dont want. I want two screens showing different things on each. Dell recommends upgrading the software on my laptop video card which is so far impossible because Intel only seems to offer windows versions of the software for the video card. So, to summarize, the monitor is really awesome when it works, which is hardly ever. Oddly, it worked well for several weeks, so Im not sure its possible to return to Amazon. I have tried many different ways to solve the problem, including turning off the feature on my computer that puts the display to sleep, playing with all the features on the monitor itself, plugging and unplugging everything in various orders, rebooting the laptop over and over, etc, etc... nothing solves the problem. I hope this information helps Macbook Pro users avoid the problems Im having with this monitor.... very, very annoying when you are busy at work!! Meanwhile my cheap old, small Viewsonic monitor worked beautifully with the same laptop, but the image was terrible.

First, let me say I really like my Dell U2412m monitor. Ive had it about a month and have thoroughly enjoyed using it everyday, and for the price point, this is a wonderful monitor with an excellent feature set. However, its not perfect. The first one I received had severe clouding in the right top and bottom corners. Of course, these come setup with the brightness at an eye searing 75%, and the clouding diminished a bit when I turned it down to a more reasonable 30%, but it was still quite evident on a dark image, and not acceptable for my main purpose of photo editing, so back it went (thanks Amazon for the easy no hassle exchange!). The second one also has a tiny bit of clouding in the corners, but only when viewed really close-up, and mostly not visible at all except on a completely dark screen. So, not perfect, but acceptable. I really like the 16x10 ratio, its a nice big workspace. The build quality seems up to Dells high standards, and I love the stand, with its easy and yet very secure adjustments. I will say that the color on my second monitor leaned toward the green, cyanish side (yuck). Unfortunately, the color controls in the main menu are not fine enough for the kind of color adjustments that were needed, but luckily for me, I found some sites on the internet that described how to carefully access the service menu, and I was able to tweak the color to perfection using some very good LCD monitor test images I found using Google. So, lets wrap it up: Pros: 1. Good build quality 2. Excellent color and picture (when tweaked correctly) 3. Easy and stable stand adjustments. 4. Works beautifully with both my new Mac Mini AND my 10 year old Mac G4 (using a USB switch) 5. Lots of inputs and USB connections 6. 3 Year warranty Cons: 1. A bit of clouding in the corners, but generally not visible during normal use. 2. Only USB 2.0 3. No HDMI input So, would I recommend this? Yes, but with qualifications. Be sure and check your screen for unacceptable clouding, and be prepared to tweak the brightness, contrast, and color. If you can live without HDMI and USB 3.0 ports, than this monitor should be on your short list. UPDATE (March 4, 2013): I really like this monitor. It has performed flawlessly over the last 5 months. The bit of clouding in the corners doesnt seem to show up in real world use. No color drift and no problems whatsoever. I leave it on 24 hours a day and it automatically goes into power-saving mode whenever I put the computer to sleep. For the price, this is quite a nice monitor. Update (Sept 5, 2013): The thing I like most about this monitor, it just works. I know that sounds simple, but in this complex world of cables, and operating systems, and weird stuff, its nice to have something that I can just plug in and it works perfectly, all day, every day. The color has been SUPER stable, with no drift. The slight clouding in the corners hasnt gotten worse, and doesnt effect my day to day photo work. All-in-all, an excellent and reliable monitor.

Ive had the monitor a little over a month now. I appreciate the superior image quality, color, screen size and stand adjustment range compared to my old 22 TN 1680x1050 monitor. I use it mainly for internet use and RPG/MMO gaming. I do have a Spyder4 Elite colormeter and using that for calibration I have very clean, bright whites and deep blacks. Colors are vivid and true (99% sRBG after calibration). * Gaming response is great for the type of games I play. I see no abnormal ghosting (all LCDs have a little blur regardless of panel type or response time compared to a CRT). My RPGs and MMOs (like Skyrim and LotRO) look gorgeous. * The stands adjustment range is awesome. I daily use the height adjustment, tilt and swivel depending on how Im sitting in my chair. Its so nice to have an ergonomic monitor that accommodates me regardless how I slouch, tip back or sit upright. Every monitor should have such a stand, but sadly most dont * The screen is very close to perfect. There is a tiny bit of edge bleed, but it in general is the most uniform monitor Ive ever own. The screen is almost completely smooth and dark when the PC first boots and there are no dead or stuck pixels. Great job there on quality control there. * Unlike a few who complain about the Anti-Glare coating I have no issue with it. Unless I have my nose very close to the screen with a light background its unnoticeable. At the usual 24 I sit from the screen I really cant see it. Whites are clean, colors are true, text is sharp (use the Windows 7 Clear Type adjustment tool) and there is no undue graininess to the screen. My previous monitor was a glossy screen, so if anyone should be sensitive to the anti-glare coating it should be me. The U2412M is just fine and I think some people are trying very hard to find a perceived flaw to obsess over. Basically, its a matte screen. If you dont like matte screens, get a glossy, but be aware you will then have to deal with reflections in bright environments. * 1920x1200 resolution and a 16:10 aspect ratio. This is a personal preference, but I like the greater height of a 16:10 monitor for internet and productivity use. If you really need to view 16:9 material without it being stretched youll be better off with a 1920x1080 monitor since the Dell doesnt have 1:1 pixel mapping. You can set it to 16:9 in most video cards so the stretching isnt evident (my Nvidia GPU can using the Nvidia Control Panel). That brings me to one of the monitors few cons. It can adjust to view 4:3 aspect material (older games)without stretching in the menu. It uses black bars on the left and right to do this, but the problem is it then shows widescreen material with black bars as well. Most monitors (including my three year old HP) can switch back and forth automatically when using a 4:3 setting in the menu. With the U2412M you have to go into the menu every time when playing old games or watching a 4:3 aspect TV show or movie. All in all this is an excellent monitor for general use and Im very happy with my purchase. Amazon (as usual) delivered quickly and their excellent return policy during the 30 day window really put my mind at ease vs. buying from a local brick and mortar store. They double boxed the monitor for shipment and thats a rarity with most e-tailers (Newegg doesnt do that for monitors).

I had two 16:10 LG monitors and at 9 months one went south. LG quit making them so they are issuing a refund. LGs customer service to this point is excellent btw. So, I ended up here looking for another comparable monitor for my dual monitor setup. In the price range it boils down to this Dell model and an Asus. If you are looking at these you will know which Asus I am speaking of. I read and researched forever it seemed and came up with two options. One may be yellow and one may flicker. Wonderful choice. If you are in that position then possibly this will help you decide. One site called TFT Central does a good job of reviewing both monitors. Both get reasonable marks with the edge possibly going to the Dell. What caught my eye is the Asus uses PWM or Pulse Width Modulation to dim the monitor and Dell does not. PWM is essentially turning the backlight on and off faster then the eye can detect and to dim the monitor the LED stays off for a longer interval. Thats how I understand it. It is said that this could cause some eyestrain in some people while reading. It reminds me of the old interlaced low frequency monitors that indeed caused me much eye strain so one strike against the Asus because I read a lot. At full brightness the PWM does not engage so it wont matter but you cant look any of these monitors for very long on full brightness so you will most likely be looking at the PWM working. Once again it may not bother many but I did not want to chance that. The Asus has some USB3 ports that may or may not work. Its the may or may not part that makes me wonder why I should use that as a criteria at all. Then there is the Dell where some were getting a distinct yellow tint and that certainly bothered me. You would possibly get the yellow tint with a Dell monitor that has a A00 revision number as reported by some here on Amazon. The numbers seem to go backwards as you read the reviews causing some head scratching. It didnt make much sense. I found a blog talking about this very subject and a fellow named Chris from Dell answered the question at some point. The A0... number starts over at 00 if there is a hardware change. For anything else like the case, stand or software change they add another digit to the revision number. So, what you have to do is compare the revision number to the date of manufacture to be meaningful. The yellow monitors appeared to be manufactured in the later part of 2013 with a revision number of A00. So I took the chance on a yellow monitor and ordered the Dell about 3 weeks ago which would have been the later part of May 2014. I received one with a date of manufacture of March 2014 and a revision number of A01. To my satisfaction there was and is no yellow tint with the unit I received. So it would appear that the one I have has had a software or firmware update based on the revision number. The part that I still find confusing is what if they have another hardware update immediately after a A00 revision? Hmm. The color was really very good out of the box and the only adjustment I have made to date is to turn the brightness level down a little. Much to my surprise it matches the LG color as exact as I can tell. I see virtually no difference. I also have a reference because while I waited for the new Dell I had an older Dell 19 inch running next to the LG and there was a major difference in color that could not be adjusted out. Last but not least I find out that the Dell U2412M and the Asus both use the same panel made by LG so any difference should only be in the electronics, case and stand. The Dell stand is very nice and the case very slim. I find the menu easy to use. The mat coating on the screen is not an issue. It looks just fine on both of my monitors. Some here have complained about the Dell warranty. That may be an issue to consider. I think they all could take a lesson in customer service from LG. Those folks have it down. So this is how I decided. Hopefully it will help if you find yourself with the same dilemma, yellow or flicker.

First off, this monitor is great and it really should deserve 5 stars. It is not a true professional monitor in terms of color reproduction and accuracy. But for anyone looking for a more premium monitor that is 16:10 aspect not 16:9 then this is a great choice. I have 3 of them running in Eyefinity mode and it looks great for movies and games. Now the reason why it received a 1 star is because of Amazons service, particularly Amazon Primes service. I ordered this monitor on Dec. 2nd at 1pm PST. During check out, Amazon prompted me to try Amazon Prime for 1 month for free. I thought this would be a good idea since I do purchase items often on amazon, and if it turned out to be good I wouldnt mind paying the fee to continue. I mean hey, 2day shipping sounds pretty awesome. So I went ahead and did the free trial and checked out; I received an email saying confirming transaction and packaging item. Wow that was fast! At night time it said shipped and arrives Dec. 4th i.e 2 day shipping. I get my tracking number soon later which also prompts the same thing arrives Dec. 4th by 8pm. Dec. 4th comes and I wait all day, but nothing. I check the tracking, it says Arrive in Anaheim, CA at 4:21am Dec4th which is roughly 5miles from where I live. I thought weird, but sometimes shipping has problems so I get a little annoyed because its suppose to be 2day shipping but Im not mad. Dec. 5th comes; I wait all day again. This time it says out for delivery at 7:02am Dec. 5th all day on the tracking. I wait until 8pm, nothing. So at 9pm I decide to contact amazon customer service via CHAT. I get to the person (Monique) and explain my situation and frustration. She gives me a bunch of run-around answers about how it got lost in the the tracking system and that the tracking isnt accurate sometimes. So I say it said out on delivery from Anaheim. does that mean its not REALLY out on delivery and its just sitting somewhere at a warehouse?? and her response was your item is our for delivery, it is in transit and then they left the chat. Just like that, no bye , just left my chat. So Im pretty mad and disappoint now and I try to get another customer service chat person. This time Ingrid A. helps me and I explain to her about my item and how the other customer service rep just left me hanging. This time around, Ingrid was actually very polite and tried to help me. She said that after looking at the tracking service it looks that my item will arrive on Dec. 6th. And that she is very sorry for this problem and is willing to offer me an extended month of Amazon Prime. I reply this is my first order with Prime and it already has this complication, why would I want to use Prime again? Then she says I understand your frustration, so what would you like me to do in order to solve this problem? I answer well, what I would like is for my item to arrive on time like it was promised, but I realize that isnt possible now. So if this was a retail store or a department store, then some kind of discount would be fitting, is that right? She says let me see what I can do. After some minutes she comes back and says I can offer you a $15 credit to your account. I said I was not satisfy with that to be honest. I even ask her if she would be satisfy. She said thats the only thing she can do for me or extend the Prime account. Wow, $15 credit or a month of prime after that fiasco? Might as well spit in my face then. I say this, isnt Amazon Prime suppose to be a premier service? $79 a month isnt cheap. Arent they trying to set themselves apart with Prime? And when something like this happens this is how they handle it? How are either of those fitting compensations to ANY costumer that wants to use their Prime service? Is this how Amazon mottos their business and customer service satisfaction? Its disappointing to see how Amazon sees its loyal customers. I end by saying, I have 3 of these monitors, the first 2 I bought directly from Dell and they did not disappoint in service. This 3rd one I bought here, but I wish I would have save myself the hassle and bought from them as well. Thanks but no thanks for $15. Really Amazon?

Bought this monitor to replace my 6 year old 24 inch TN dell. Unlike some other brands, Dell never let me down. Its not a coincidence that most IT companies use Dell. So when I saw this 2012 model still best selling and having rave reviews, I knew it must be a good buy. And indeed, the user feedback is justified. This is a huge improvement over my old TN screen. I didnt even realize how off the colors of the TN display were till I put two monitors side by side. No more blurry dark mess on top of the screen and no more an overly bright bottom. The backlight is even, no noticeable leaking, viewing angles are awesome. On my old monitor, I had to readjust the screen constantly (which wasnt really helping much). Other less major, but very nice features are: - The brightness can be set extremely low. On my old display, I kept it at 0, which is equal to only about 22 on this one, which means Ill be able to lower it even further if I decide to work at night without lights on. - The height adjustment can be set exceptionally high, and the stands base isnt very thick or large, which allows the keyboard to be put over it, if desired. Together this eliminates a need in a Vesa mount. Though I might still mount it because I like to push and pull my monitors a lot. - It has a blue led, which is the new green.

This is an excellent monitor with a sharp, clear picture. I like the 10:16 aspect ratio which gives a taller screen for the same nominal size. It is great for business applications. I worked in an office where we had at least 30 of this exact model and everyone really liked them. As far a I know, none had any issues with dead pixels or other failure and they were used every day. A super great feature is the very adjustable ergonomic stand. it is very solid and has very good range of height, tilt and swivel. I love the thin matt (non-shiny) edge boarder and the non-glare screen. A couple of reviewers have complained about the non-glare screen being grainy, but I have no idea what they are talking about. The picture and color are excellent. This has DVI and VGA inputs, but no HDMI which may be an issue to some. But the DVI will give you the same picture quality and if you want decent audio sound with any monitor you will need separate speakers and hook up any way. Very few monitors have built in speakers that could use the HDMI sound, and those that do are usually poor quality. I got the Dell AX510 sound bar to go with this and it fits great, looks good, took 5 minutes to easily install, and sounds good, (better than typical built in speakers). But if you want rich, high quality stereo sound youll need stand alone speakers.

Just got this a couple days ago and it is a very nice monitor. Looks great! I was worried about some of the reviews I read about anti glare coating, displayport issues, etc, but everything seems to be in order, and I couldnt be happier. The larger box it came in was pretty mangled when it arrived, but the monitor was unharmed. This Dell Makes my other monitor look worse than I thought it was by comparison (ASUS VS248H-P), so now I want another one of these ;) The increased resolution really makes this seem a lot bigger (a good thing :) ) The colors look great out of the box, so I dont feel the need to calibrate, but I may run it later on to see how it changes things. Though, I havent had that great of luck with the Spyder calibrator previously, so I may just enjoy my monitor as it is (which looks great right now anyway). Very bright picture as well, and Ive actually turned down the brightness from the default 75, to 50. I have it connected to my PC, which uses a Nvidia GTX660 via displayport (with HDMI going to my ASUS). Hopefully itll last for a long time without any problems, but for now, very happy.

Where I got this monitor: Amazon Is this my first U2412m: Yes Date of manufacture: June 2014 Revision code: A01 Yellow Tint: I guess? has a yellowish color compare to my primary screen (which is a 13 MacBook Pro non-retina version) I tried varying the color temperature and it is still yellower than my Apple screen. That said, its on an acceptable level. As a side: When I first bought this macbook, I actually experienced the same problem with the new laptop and my Apple monitor, and I got a replacement from Apple but they said it wasnt a fault, its a difference between what manufacturer produces the monitor (I think its LG VS Samsung). So I am happy with my whiter laptop and this monitor is great for me. UPDATE: I just figured the yellow tint was due to the software f.lux I have on my laptop that changes the color temperature according to the time in a day. After I quit the program, yellowish screen is gone. I guess all I can say about that is the Dell monitor displays more reaction to the color temperature than my Apple laptop. I saw a lot of reviews on Amazon discussing the revision and so on. I was extremely stressed out about that, and decided to give Amazon a try since I really needed another monitor that can be in a pivot position. When it got here, on the side of the Dell box, it stated the revision code and the manufacturer data, I guess I was happy with what I got. The stand that came with it is amazing, it can do all kinds of rotation angle and it makes my work station more ergonomic than other monitors (+ normal stand) could have. Just order it and voila, no need to get a separate stand, nor measuring the eye level and pile books underneath it. It just magically works. Seriously, I love it. I searched for some high resolution wallpaper that could fit with this 1200 X 1980, and it makes the monitor ever prettier. The only down side is: I wish they could implement some kind of software that you can adjust the brightness from the keyboard and some sort of shortcut to rotate my screen.

Pros: + Nice 1920x1200 resolution. I dislike the recent trend of making computer monitors 16:9 instead of 16:10. + Extremely bright on full blast + Great and sturdy adjustable stand with a 90 degree swivel (great for coding or web use) + Anti-glare coating isnt as noticeable as other reviewers claim + Matte screen. I hate glossy screens with a passion. + Convenient USB ports on the side and back + Have yet to see a single dead pixel. + Decent response times. Ive done some gaming on it and havent noticed much (if any) ghosting. Cons: - Backlight bleed. Mine isnt as bad as others Ive seen, but its still there. Lowering the brightness seems to help; you can turn it down to zero even and still have a bright picture. Its really only noticeable if the entire affected area is black. Im not too upset with it, and I dont feel like playing the RMA lottery to see if I get a better one and then end up with a worse one instead. The bleed is my only real complaint. If youre looking for a quality monitor in an affordable price range, I would definitely encourage getting this. Dells monitors have always impressed me with their quality, and a cheaper off-brand monitor wont look as good (even if its the same actual panel).
