Dell U2713HM

Just spoke with a Dell rep - looking at $640ish + tax..

hmm thats not too bad. i would be happier with 600$ though, especially since i would want to sli another 670 to keep my settings and fps

Trying to decide between this, and a Apple Thunderbolt 27".. Just picked up a new Mac Mini, and have a few Macbook Pro's here at home so for the price and what I will use it for, a refurb or company discount Thunderbolt display might make more since to me vs dell at this price.
 
Well, it's me again... got another U2713HM from Dell to see if I could get one without the cross-hatching effect on the screen. Although better than the first monitor, it's still there on the second. If this was a $200 monitor then maybe I wouldn't care so much, but for nearly $800 I expect more. On top of that, now that I know what I'm looking for, I don't think there's any way I could just ignore it. So, reluctantly I think this one is going back. It's too bad... I really was hoping this would work out.

Went to the apple store today to replace a burnt up power supply for my macbook, ended up walking out with a thunderbolt display. Was $919 + tax w/ my discount. Not bad I guess, I'll probably end up using the gigabit + tb addon when using a macbook air in the future - and just regular tb display when using the mac mini on daily duty.

Do you happen to have a Fry's around?

If you do, I'd try to do a price match or return. J&R might even do a price match over the phone.

Damn - That's cheap! I don't think Apple will price match will they?

*Update - Just called Apple but since this is an in-store pickup only, they cannot match the price. Even if they did match, it would only be up to 10% from retail so it would only save me $19 because of the EPP pricing*

Oh well. Maybe I'll take a trip to Delaware to take my wife shopping and I'll bring the display to return and pickup a new one and save the $55 in taxes if I end up in DE in the next 13 days..

are you checking the revisions and the manufactured date? you should and then let us know. that way we can look for this on ours if our revision matches yours

Both monitors have a September 2012 build month (they don't give specific dates) and are both revision A00.

I know exactly the 'cross hatching' you're referring to and I was trying to google this exactly yesterday and then I found your post. I just received my U2713HM sight unseen based on the reviews and started noticing yesterday while visiting multiple websites with white backgrounds or when check my email, etc. that there seemed to be faint white diagonal lines running across significant portions of the screen. I wasn't sure if it had something to do with the anti-glare coating or not. I've noticed it at any distance from screen less than ~30". I've also noticed that I this issue goes away when you are looking at parts of the screen showing the issue head-on. The problem is, in my opinion, you're always going to be looking at either the top or bottom of the screen as some angle. I tried different power cords, outlets, different computers, cables, etc. None of it changed the issue.

Is this "normal" for this monitor? I've never seen anything like this before with any other LCD monitors I've owned. I'm trying not to focus on it, but I noticed the issue almost right away without inspecting the monitor with a fine-tooth-comb. I think this might drive me nuts.

For what it's worth, the build date on this monitor says September 2012.

I'm really not sure if this is normal for this kind of monitor or not. Yesterday I checked another sample at a different store with my own eyes. The shop assistant opened the factory sealed box in front of me, at first glance the monitor was perfect, no dead pixels or backlight bleed (or if it had it didn't bother me), unfortunately the cross hatching was there. I inspected it several times from different angles with different sample images. However, I asked the assistant and he said he couldn't see it. (he was in his 50's I think so maybe he had not very good eyes but in the previous shop where the assistant was in his 20's could see it immediately, latter mentioned this issue might have something to do with the monitor's coating because it is visible from specific angles only).

I'm a bit confused now, I could only check 2 samples with my own eyes and both had cross hatching, the second one had a 2012 July manufacture date (I forgot to check the date for the first). I asked an owner at my country's biggest local forum and he said his monitor (2012 September manufacture date) is perfect, no cross hatching or other issues at all, he purchased it at the second local store I visited yesterday.

However both stores in my country have a special warranty for an approx. 25 Euro extra in addition to the standard Dell 3 year warranty (calibrating the monitor costs approx. 17 Euro plus). I was told if I would choose this extra warranty, the monitor I picked will be inspected thoroughly for dead pixels and exchanged immediately on the spot for a perfect one. (this warranty only covers zero dead pixels unfortunately)

Maybe a newer revision could alleviate or solve this issue?
Anyone have an idea when to expect a new revision or have reliable information about this date?

How close do you have to be to see this? If it is closer than regular viewing distance, why is this a problem?

thanks dude.

i think people were saying the monitors dated later were significantly better quality.



my father bought his u2412m like 6-8 months after me and his is leaps and bounds better then mine.
 
I've been using the U2713HM for an hour or so, and I did notice the crosshatching that people have mentioned so far. It's not extremely intrusive, but I do notice it when I try to look for it, and it's really only visible on white pages. The one I'm testing is Revision 00 and was manufactured in September.

I have an old graphics card (5770) with only one DVI-D, and I unfortunately can't run the PB278Q and U2713HM side-by-side for comparison. In terms of backlight, the Dell has a little bit more pronounced bleed in the bottom corner of the screen. Both monitors have BLB, but that one spot on the monitor stands out.

In terms of build, both are just really solid. The Asus is a bit heavier, but I really couldn't say one was better build than the other. The adjustment on the Asus a little bit smoother, but how often do you adjust the height?

I like the OSD on the Dell a bit more just because the options are right next to the buttons, so it's easier to see what each button does, whereas with the Asus you have to go back and forth a bit between the OSD screen in the center and the buttons on the bottom right. This is a really minor thing, though.

I'll try using the Dell a bit more to see if there's any difference in eye strain/fatigue. I think just being aware that the Asus has PWM will act like a placebo and make me think my eyes are more strained than they actually are. I need to spend a bit more time to really see if I prefer one of the other, but overall I'd say they're both really good monitors.

I can't speak for everybody else, but I saw this issue on both monitors I tried them at what I feel is an acceptable distance between my eyeballs and the screen. I could easily see this issue in my normal seating position at my computer desk, which put my eyes 24-30" from the screen. Sure, at 36" I didn't notice the issue. But should you have to sit 3' away just to make the issue go away? Personally, I don't think so.
 
I forgot that HDMI 1.4 (came with the Asus) supports 2560x1440, so I actually have the U2713HM and PB278Q running side-by-side. The HDMI cable didn't support 2560x1440 on the U2713HM, however.

For my comparisons, I used factory default settings and then adjusted the monitors to both 0% and 100% brightness.

The PB278Q has more vibrant and "deeper" colors. There's a discernible difference on the taskbar color on the two monitors, and also when I split program windows between the two screens. The U2713HM seems to have a yellowish tint, and things like the borders of windows and text look just a little bit fuzzier on the Dell. Maybe the AG coating is stronger on the Dell. With that said, however, the AG coating on the U2713HM is so much better than the AG coating on the U2711 (and U2410, U3011). It could totally be possible that the U2713HM has more accurate colors, and I don't have a calibration tool to adjust either screen, but I'd describe the U2713HM as duller.

BLB is pretty similar on both, except the U2713HM has bad bleed on the bottom-left corner. This will obviously vary from panel to panel and isn't representative of of the models as a whole.

The Dell does have that crosshatching that people mention, but I only notice it if I put my face 6 inches away from a white screen. I'll have to play around with Photoshop a bit to see if it'd bug me on things like photo editing. Currently not a deal-breaker for me.

I did a test for PWM by waving my hands like an idiot at the screens, and there is a strobe light effect on the PB278Q when the monitor isn't at 100% brightness, which was expected.

Remember that this isn't the most rigorous comparison between the two, but based on my initial impressions I think I like the PB278Q more. Considering the U2713HM vs. U2711? U2713HM is easily the choice for me just because of the AG coating alone.

EDIT: I was using last.fm, which has a white background, and the crosshatching was visible, even at normal viewing distance. I also found a couple of dead pixels on the U2713HM. Boo.

I'm not sure about this but from 50-60 centimeters (approx. 20-24 inches) I could notice it. As far as I know there's an English proverb: "ignorance is bliss". It's hard to ignore when I know it's there even if I can't see it at the moment, leaning forward a few inches and it's there. I try to find someone who can confirm me a 100% that his monitor is cross hatching free or I could see it with my own eyes that it's not there. As I mentioned in my previous post not everybody notices it, the older shop assistant couldn't see even from a few inches staring at minutes but the younger noticed it immediately.

In the PB278Q thread one common discussion is about PWM backlighting, not everybody affected/noticed but it could cause eye strain and/or headaches for some people. (this was the other 27" IPS 2560x1440 monitor I was thinking about but it's difficult to get one in my country due to very limited stocks and therefore the rma process is a real pain too if it's required)

By the way, I'm not buying any monitor without checking a working sample first in a shop with my own eyes.

Anyway, I'm planning to use this monitor for 3-5 years so I'd like a perfect one for 560 Euro. (my current monitor is a bit more than 3 years old, otherwise I used my previous monitor for 6 and half years)

In the end maybe I wait a few months or next revision...
 
this Dell looks to be very good monitor.
- weak AG coating
- slight sRGB overcoverage but with gamut correction
- good response time without reverse-ghosting

It's just sweet, much better than U2711 imho :)

They should make 24" version of it with 16:10 ratio :)

Apparently there is a U2413M in the works, again apparently it will replace the U2410, so apparently it will be wide gamut. But I would expect it to have a lighter AG coating than the model it replaces. I would also prefer if the U2412M had the lighter AG coating, I think it would be my ideal monitor (I would prefer 16:10, but not completely against 16:9), just a shame you need to spend 2300:- for the U2412M, but pay 5500:- for 3" more :(
 
Just a heads up. I too have a 2713HM and it has the exact same buzzing issue that you describe. I've tried everything you have, changing cables power outlets etc nothing works. The buzzing changes depending on what website I am on, Wikipedia's home page is really bad. I asked Dell for an exchange and I got the new monitor on Friday. Well that one does the exact same thing as well. My first monitor was made in Aug and the replacement was Sept. I will probably just live with it. I only hear the buzzing when its dead silent in my room which is almost never. Its just annoying that it does it sometimes. I could try for a 3rd replacement but I may wait a bit. So your not alone looks like their are more units out their that do the same as yours and mine...
 
I've had a couple more days with the U2713HM and have continued to use it alongside the PB278Q. For some reason the "Standard" mode on the U2713HM has a yellowish tint to it. I then tried the "Multimedia" mode, and now it's very close to how the colors are on the PB278Q. The colors seem to be a little sharper, and that yellow tint is removed.
 
I think that "yellow tint" you see is a warmer color temperature then the one that's on the asus for the given settings that you're using.

TFT Central has good review on both displays. Read them to see what settings they used were best. They should also have display profiles on their site as well.
 
I'm going to have mine returned due to the image retention, which is a shame.

I'll be buying the PB278Q instead.

No idea if it's related, but my 3007WFP has always buzzed depending on the brightness settings. Generally the brighter I set the monitor, the louder it gets, although there's a few settings (0%, ~50%, ~70%, 100%) where it completely disappears (must be frequency cancellation or something). Thankfully I use my monitor on the lowest brightness, but try fooling around with your brightness controls to see if it helps.
 
Finally got through to the Dell contact I have. She quoted for the U2713HM, $599.25 + tax. If interested PM me.

USA only, sorry.

Hi all

I am in India. 7 days ago, I purchased 4 Dell U2713HM displays for a new computer upgrade (my old computer is from 2006 and I had been saving to get this). Right now I have an old NVIDIA 7600 GS card with one dual-link DVD-D output, but that is enough to test these displays one by one. The rest of my new computer is not yet ready.

I contribute code to some open source graphics projects and I bought these displays as they have 8-bit panels and cover sRGB.

These are from the September 2012 batch, with A00 revision. So far I have unboxed two displays. My impression is that except one issue, these panels are very good. That one issue is image retention.. I'll explain it shortly. I haven't seen color bleeding in these two displays and am unable to detect the hatching pattern normally (unless I look very closely and even then it's not very visible). My eyes are 34 years old.

But image retention is somewhat annoying, especially if there is some application that causes it to show, or if you go looking for it. I have tried to learn how image retention happens, whether it is a design or manufacturing issue, and whether a different batch of displays would fix this problem. I am worried that image retention could become permanent. There doesn't seem to be any authoritative information on this topic either from the panel manufacturers or Dell, or anyone else for that matter.

I didn't know about image retention until I accidentally saw it on these displays. I had a Firefox window open for a while (about 20 minutes) in a single place. The window was mostly white with a few lines of black text. Then, when I opened an image in a new Firefox tab (new versions of Firefox fill in a grey background when viewing images), a faded copy of the old window was visible in the grey areas.

I then set my desktop background to #404040 to check this behavior further, and it happens every time. You cannot notice the retention in any other image or color being displayed except these dark greys.

After this, I tried reading about this problem and found this thread and other threads which complain of similar issues with LG panels on the MacBook Pro with the retina displays. The Dell U2731 also has an LG panel. The tftcentral.co.uk article on this display mentions that the AH-IPS panels have been used to identify the super high resolution panels on the Apple "Retina" displays too. So maybe this is a design defect or a defect in manufacturing AH-IPS panels. I don't know.

http://www.tftcentral.co.uk/reviews/content/dell_u2713hm.htm

The following page lists some reasons why this may be happening:

This retention is a problem for me. As a graphics programmer, I often work in shades of grey. It may not be so bad for the casual computer user who may completely miss seeing it. For example, if you play a movie after browsing, no image retention is apparent. But could the retention become permanent? If it retains an image only after 20 minutes of it being there at 20% panel brightness, that's scary.

I called up Dell yesterday. They offered to replace the display with another one, but the only vendor who's shipping this in India (Dell don't directly sell to customers here) has units from the September 2012 batch alone. If this is a manufacturing defect, the replacement panels will have it too. They are going to get back to me on Monday about whether I'd get a replacement, or another model, or my money back.

I am unhappy with how things have turned out. Other than the retention issue, this is an excellent panel and draws about 40W at full brightness and about half of that in more normal brightness levels, which is awesome. 4 of these displays draw less power together than a single 30" CFL-backlit display from Dell!

I hope they are able to find the root cause and give me a replacement that does not have this defect. I'd rather have displays without these issues than my money back.

Please can other HardForum users check something for me? If you have a Dell U2711 or a Dell U3011, please can you check and tell me if your panel suffers from image retention? Make a 64x64 black-white checkerboard pattern (there is a script in GIMP to do it) filling the entire screen and leave it on for about 30 minutes at > 50% brightness. Then, fill the screen with #404040 (dark grey).. you can easily do this by making such an image in GIMP, and viewing it full-screen.

Also try a web browser window that covers about 30% of the screen with a white background webpage. Then switch to a #404040 grey filled screen.

If these H-IPS displays do not suffer from the problem, and it's just the AH-IPS displays which do, I'll ask Dell to give me those as replacements instead and pay the difference in price.

It would also be nice if we can find a contact at Dell who knows about why this problem happens technically and how they intend to address it.
 
Amazon has price matched Costco, and they're selling it for 649.99 now. Good deal for people who don't get charged tax by Amazon and want a good return policy. It's temporarily out of stock (happens every week or so), but you can place an order and have them ship it when it's available. You'll have to click to get other sellers and find Amazon.

As far as I know, there is an option in the osd for this kind of problem, maybe worth a try if you have to send it back anyway...

It's called "lcd conditioning" under "other settings" and you can find it here in the osd, if I were you I'd try it. It is mentioned in the U2713hm user guide as well. (search for "conditioning")

Other solution maybe which I read at a different forum, and it is not convenient, that turning off and completely powering off (yes disconnecting the power cord from the power outlet) because according to the comment this issue is temporary only. I've found this explanation, I'm not sure if this is correct:

"You probably have a Dell monitor, which has an option in its menu to perform "LCD Conditioning" to fix image retention. It's very rare that a home PC will require "conditioning", but image retention can happen if you have one image on the screen for days at a time. Pixels can become polarized when sitting at one charge, but it's not permanent, as is the case with phosphor-based displays like CRT and plasma.

Conditioning will just cycle the polarity of all the pixels so that they lose their polarity, and it is completely harmless."


I do not own a U2713hm but still intend to purchase one however first I'd like to find one sample which do not have cross hatching issue, so far I could check 2 samples and both had them. Maybe I could check a third next week with my own eyes...
 
Ok so I had the Asus PW278Q for a not quite a week. I also bought the Dell 2713HM. The Dell has a tad more glow to it and has this strange yellow in the left corner that really stands out about 1/3 up and to the right 1/3. And really stands out in black. And it did NOT show up right away. Thats the strange thing. But once it did it was there to stay.

For ME the Asus wins. That yellow just kills it for me. And from all the other pics I have seen thats it. You cant see it just reg desktop. For the price should NOT be anything like that. Did not have any cross hatching no dead pixels.

Again for me the Asus wins. Less glow no yellow lol and for those that care has speakers has HDMI that supports 2560x1444 not sure why one would need it. Can switch on its own between ports ..you know what I mean.

What about PWM? Don't you have any headaches or eye-strain reported in PB278Q topics when you're using it for hours? Or any "strange tearing" at darker shades in games, like BF3? (according to comments PWM causes these "effects")
 
Almost ordered one. But all my cards were getting declined by Dell for some reason and the order was auto-cancelled. Everything else I used them for today went through no problem. /shrug

Maybe my bank was blocking them thinking they were fraudulent?

Is it the same as image persistant? or after image? or whatever they call it now-a-days I think it is a common issue with all IPS displays - normally you can fix it by displaying an all white background for the same amount of time you had the previous image that caused the issue.

But if it is too severe you many need the panel replaced, and it is NOT a manufacturer issue, because image persistant or after image is caused if you leave a static image too long with no screen saver.

The window was mostly white with a few lines of black text. Then, when I opened an image in a new Firefox tab (new versions of Firefox fill in a grey background when viewing images), a faded copy of the old window was visible in the grey areas.

Please can other HardForum users check something for me? If you have a Dell U2711 or a Dell U3011, please can you check and tell me if your panel suffers from image retention? Make a 64x64 black-white checkerboard pattern (there is a script in GIMP to do it) filling the entire screen and leave it on for about 30 minutes at > 50% brightness. Then, fill the screen with #404040 (dark grey).. you can easily do this by making such an image in GIMP, and viewing it full-screen.

Also try a web browser window that covers about 30% of the screen with a white background webpage. Then switch to a #404040 grey filled screen.

If these H-IPS displays do not suffer from the problem, and it's just the AH-IPS displays which do, I'll ask Dell to give me those as replacements instead and pay the difference in price.

It would also be nice if we can find a contact at Dell who knows about why this problem happens technically and how they intend to address it.

Hello Muks

If you read the thread, the image retention on the Dell U2713HM has been very well documented by numerous users. I also had it, along with other issues such as screen tearing. I eventually returned it for the Asus PB278Q, which I absolutely love. I recommend doing the same and not waste your time with the problems and lottery of the Dell.
 
What about PWM? Don't you have any headaches or eye-strain reported in PB278Q topics when you're using it for hours? Or any "strange tearing" at darker shades in games, like BF3? (according to comments PWM causes these "effects")

I played Halo for more than 3 hours continuously on my Asus PB278Q and I did not suffer any eye-strain or tearing within the game. I notice no input lag, or blurring either for that matter. You just have to give it a go and try for yourself. ;)

Thank you for your response and I'm glad that you are satisfied with your new monitor but it seems the PB278Q is a no go for me.

First of all I don't purchase any monitor without checking a sample with my own eyes and even if I live in my country's capital, there isn't any vendor who has a working sample which I could check. Secondly, my country (in Middle-Europe) has a strict rma policy which means if a product is within manufacturer specs and has no defects based on manufacturing then it won't be replaced no matter what anyone says (therefore pwm and it's effects are not covered by the warranty here). Thirdly, I asked a few vendors about Asus monitors here, all of them suggested avoiding Asus monitors because stocks are very-very limited here and therefore a rma process takes a few(!) weeks. That's what I was told by different sources and maybe that's why only 4-5 e-tailers sell Asus monitors even online in my country and of course they never have a PB278Q in stock (or at least since this monitor should be available officially here).
(In contrast with Dell monitors which are sold at least 20 e-tailers here and the U2713hm was in stock early September)
In short, the PB278Q is a no go for me because of these reasons in my country.

And thanks for the info, maybe I ask around again if there's a change about Asus monitors supply and rma processes here...(my bet there isn't any)

My main reason for Dell is that only one retailer in my country has a very user friendly (in contrast with the "default" in mentioned above) special rma policy for an extra fee but I asked multiple times, not for Asus monitors for the above reasons, only for Dell.

Yesterday, I drove 130 km (80 miles) to check a third U2713hm with my own eyes, this one had cross-hatching too, however the 29-year-old owner could not notice it even from 10 cm (4 inches).

To sum it up, 2 out of 3 person standing beside me could not see the cross-hatching when I could, only the youngest (shop assistant)...

In the end, I wait a half year, maybe a new revision fixes this hatching for the U2713hm or a new model will be released...
 
I have a Macbook Pro Retina. The text quality on the retina display is incredible. I am considering Dell's 2713MH display. My question is to those of you who have purchased the 2713MH. Is the text real sharp? The retina display has spoiled me and I would not want a severe drop off in text quality. Thanks
 
I hope they are able to find the root cause and give me a replacement that does not have this defect. I'd rather have displays without these issues than my money back.

In reply to my own post, I unboxed one more display (from the same September 2012 batch) which does not have the image retention issue so far. I have been using it for 2 days now. So I'm going to ask Dell on Monday to send me replacements for the others which have the image retention issue. I guess that on this panel the image retention is due to either a manufacturing defect, or some material defect.

Others have recommended that I return the displays to Dell, get my money back and try another vendor. But I'm going to try and get good displays from Dell, now that I have one good panel. I like the displays otherwise: IPS, 8-bit sRGB, ~25W draw in normal brightness. With 4 panels, the power consumption quickly adds up. I may not like a different vendor's display after all (PWM, PVA panel, etc.).
