Indeed, the only games I can't play at 2560x1440 are those that never really supported widescreen or 16:9 widescreen properly to begin with.
I just received my U2711 from Dell and have a problem I haven't seen mentioned: When displaying a solid white image on 2/3 or more of the screen, the monitor emits a faint high-pitch whine.
Also, when the monitor enters power-save mode, there is another, slightly louder, high-pitch whine. When the monitor is off, it also emits the whine, although slightly quieter than when in power-save mode. Disconnecting the power cable with the monitor turned off causes the whine to ascend in pitch over the course of about a second, then stop. I assume this sound is being emitted by the power supply, and the ascending pitch just before stopping is the power supply discharging.
Is this normal and has anyone else with this monitor experienced a similar issue? Will it stop after some use? Should I contact Dell regarding a warranty replacement?
Edit: I spoke with a Dell service rep via chat and he kept trying to blame it on my video card or PC's PSU. I fail to see how the input device would have any effect on a sound emitted by the monitor in power save mode or when turned completely off.
Additional info and troubleshooting steps I've tried so far:
The monitor (and pc) are connected to an APC battery backup that is less than 1 year old and operating below 50% load.
I powered the monitor off, then unplugged it and reconnected it a couple times (at both ends) when testing earlier - this is how I discovered the briefly ascending pitch when disconnecting the power cable before the whine stopped
I also tried moving the power cable from a battery-backed outlet on the UPS to a surge-only outlet, and back. Each time it produced the same behavior.
When I get home, I also plan to try using a different power cable that I have laying around. I will probably also try bypassing the UPS, just to make sure.

Does it make the noise when not connected to the pc? Also try a different outlet in your house that is on a different circuit to see if the noise goes away to rule out electrical noise. Most likely dell needs to replace it.
Those two things are on my list of a troubleshooting steps to try when I get home (I only had time to hook it up and play with it for a few minutes before heading in to work).
To be fair to the Dell rep, he did admit that it was probably some sort of power issue and didn't continue to insist that it was the PC after a bit more discussion. He also directed me to the Customer Care department if I believe it is defective, and noted that they may also be able to replace it if needed, but I want to try some more troubleshooting before going that route. All-in-all, pretty good customer service.
At work I recently switched to using a 27in iMac (ditched laptops for an iPad 
) and have been really impressed by the screen, and when I go home to my PC to game on my old 2407FPW, it feels a lot smaller.
Since the U2711 is essentially the same panel when it comes to size at least, I've been looking at getting one and like the fact a few ebay sellers offer a $20 pixel check before shipping (I'm terribly OCD about dead pixels and went through 4 2407s until I found a perfect one).
Did anyone make a similar upgrade? I like the finer dot pitch, and understand that in comparison shots the 2407FPW isn't much smaller vertically. Still like the U2711 a lot though.

Now there is choice:

Yeah there is but lack of other connectivity options makes it completly useless.
hello all,
I just got dell to replace my U2711 that I purchased last March. It had a shimmery purple/green haze on the left half of the screen. The very helpful rep had me run a few diagnostic tests, determined that I needed a new monitor and then processed a request for a replacement.
Well, the replacement came today in a nondescript box that had "refurbished" on the mailing label. So, I obviously got a refurbished monitor as a replacement. I've hooked it up and it looks (aside from a few blemishes on screen) and works fine. I'm just wondering if this is standard practice for Dell. It irks me a bit that they seem to be cutting corners and not sending me a new monitor, but if it works, then I guess that's all that matters.
Any thoughts?

^Dell will only send you a new replacement within the 21 days satisfaction period. Otherwise you will receive a refurbished unit. I've received three new Dell U2711 this month and last month and they all have various degrees of green-pink tint so I'm sending them back for a refund. The defect is really noticeable on solid light backgrounds. It's extremely distracting to me.
Not completely useless to someone who will only ever use it via displayport. Personally, I think a single input / type does reduces the value and utility of this monitor.

Well I switched to DVI-D from DisplayPort a few weeks ago because I was just so annoyed at my windows being moved around automatically while I was away. Doesn't do that with DVI.

now i have seen a LOT of people complaining about the anti glare coating, my question is: is it really that bad? and is it different from the matte screens found on most TN panels?

It is a fairly petty complaint. Most people at home would prefer to take a softer coating, like on some PVA panels, but there are more important things to concern yourself about, like actual performance.
It is a somewhat petty complaint but we don't all think the same. For some, the graininess of the monitor is simply intolerable and can't be ignored no matter how much they try to ignore it. For others like me, I noticed it at first when I looked for it but after that it's basically out of sight out of mind.
I do agree that the constant complaining on the forums is a bit excessive. Yes, the AG coating is fairly common place for monitors now. Yes, it sucks for people that are annoyed by it. No, complaining about it on the forums every single time a display is the topic won't change the manufacturers' minds. </rant>
On the other hand, the brain is very susceptible to bias. I wonder how many people that are complaining about it wouldn't have even noticed the anti glare coating if people weren't posting about it?
To save starting anotherr thread, i may be getting one of these monitors with a new system. What i want to know is though, what sort of cabling's will i need to get full 2560 x 1440?, i would be using a pair of GTX 480's in sli *OR* 1 ATI 5970/5870 (tri-fire)
Would I be able to get 2560 x 1440 working with a normal HDMI Cable? - or would i need somrthing else thanks

so basically its the same anti glare i have on my crappy tn samsung monitor then?
No.
Single-link DVI can only transmit up to 1920x1200 at 60Hz. To do higher resolutions (including 2560x1440) at 60Hz, dual-link DVI is required. Single-link DVI uses 12 pins, dual-link DVI uses 24 pins, HDMI uses 19 pins and Displayport uses 20 pins. HDMI and DP achieve the higher speeds required for higher resolutions or higher Hz by sending more data through the same pins, while DVI achieves the higher resolutions or speeds by adding more pins in dual-link mode. HDMI and DP cables can transmit single-link DVI because they have more pins than necessary, but there is no way for HDMI or DP to transmit dual-link DVI because they don't have enough pins.
Edit: I speak here of converting HDMI from your video card to the DVI port on the u2711, because the u2711 is not capable of doing more than 1920x1080 through its HDMI port. According to the documentation, you can only get 2560x1440 on the u2711 through dual-link DVI or Displayport.

The complaint about AG coating is fair and very well justified for certain types of usage. The monitor is useless for one of these type of work - texture artists, digital painters, designers, photo retching images like removing dust and scratches, etc. The grain prevents a proper feedback of editing and creating artworks and images. I have this monitor and I like everything about it except that horrible grain that interferes my professional work. I use it together with a second monitor to verify that certain details in my artworks are as intended. I will remove the AG coating after its warranty expires. However when I use the monitor for everything else like watching photos, movies, browsing, reading, etc, the grain doesn't bother me at all. It is like watching photos printed on a textured paper, the problem is is when I want to create images using my own textures.
No it is not. The sparkly AG grain is only on IPS displays. And all IPS displays are manufactured by LG using the same coating.
That not true, the AG on my 2233rz was horrible, worse than my u2410.

2233rz is a TN panel. I haven't seen it but TN panels do not have the sparkly grain type of coating. They have a symmetrical raster (like a mosquito net pattern) which is more noticeable on monitors with higher dot pitch. In your case you are more sensitive to that TN pattern than the grain.

I dont know about that "symetrical raster", what i know is that i removed te AG on the TN and goodbye dirty colors
. I have a viewsonic vx2025wm (p-mva) that originally come with a very agressive AG (i removed that one too) , my point is that the problem is not IPS exclusive.My english sucks
.The u2711 is limited to 1920x1080 over HDMI (see the documentation). This is not a limitation of HDMI, but a limitation of Dell's design of the u2711; it will not do 2560x1440 over HDMI regardless of the version or quality of your cable or video card, which is a really unfortunate choice by Dell. There's a big thread about it here:

As a new U2711 userer, I've been pretty much delighted with it. Such and amazing picture on this thing. I find for FPS games it's a little laggy, but my previous display was a CRT, so I was pretty much expecting a bit of a step down in response. It would however still be nice to improve it. Are there any tricks to reducing it's latency at all?
My major gripe right now is sometimes the monitor doesn't seem to realize it's getting signal after I reboot. It goes into power saving mode and doesn't seem to want to wake from it. Sometimes, I can turn it off and then back on again, and it works, other times it's like nothing will wake it. I have same issuen when trying to get into my bios, it just doesn't seem to recognise it's getting signal.
Anybody with insight as to what is going wrong here?
It's hooked up to a XFX 5970 Black Edition via the included dual link DVI cable.
Thanks

It isn't just the U2711. There is no HDMI output on any graphics card that would support that resolution anyway.
In theory the spec allows for up to that speed, but it doesn't demand it.
In reality everyone just kept implementing the same speed as HDMI 1.2.
I have two u2711's and I would like to plug them into my mac pro 5870 graphics card that has two mini-displayports.
Could I get a cable that goes from displayport to mini-displayport?
I've dealt with the dvi-d to mini-displayport adapters before and have been dissatisfied with the inconsistent performance. i'd rather just go from DP to mini-DP with one cable.
My apologies if this has been covered earlier. It's late and I'm too tired to look.

DVI, HDMI and Displayport all have exactly the same image quality, because they are all digital. They only differ in features. Generally speaking, if your monitor and video card have DVI options, that's the best option because DVI is the most compatible and least likely to cause problems. It's when you have cheap monitors with only one non-DVI choice, or using consoles, or multi-monitor setups like Eyefinity, that you need to delve into HDMI or Displayport.
Going by this discussion, the final answer seems to be that a simple DP to mini-DP cable should work because they are electrically the same. Monoprice has them in various lengths for low prices.
Take one of these http://estore.circuitassembly.com/products/Mini-Displayport-to-Displayport-Adapter-Cable.html and you should be fine.
Your intermittent issues with what appears to be signal strength sounds very similar to my problem.
My main problem right now is when the screen goes to sleep, I can't get it to wake back up, and I have to power cycle the monitor to 'see' a signal again. I originally had issues when I first installed Win7 Ult and the Windows security warnings popping up whenever an app was trying to access a secure area, Windows sort of halts and prompts the warning message, and at that point my monitor would loose the signal (back to normal after a power cycle). Same issue intermittently when starting games up (the flipping of res, video card engine, etc).
I've never had an issue with the monitor 'signal' when going into the BIOS or after a reboot though. I don't have the exact same problem as you (you seem to have issues when in the non-native res), but it sure does seem similar. I'm connecting via DP and haven't tried dual-link DVI but I think that's my next step.
What I still am not 100% sure about is whether the problem is video card related or the monitor. I've always assumed it was more likely to be the video card (Sapphire 5850 game edition [non-overclockable]), and have been waiting for video card prices to fall a bit so I can RMA this thing without being out-of-commission for 3-4 weeks (was able to convince Sapphire fairly easily it was their problem, although it's still not conclusive).
I've asked before on these forums, but your case is the only other one I've seen similar on here.

i just got the monitor for 757 CAD before tax. Came to 850 after everything.
But im having some problems... All the smaller icons/txt seems to be pixelated... Movies or bigger images are fine, but icons and txt are all pixelated... help!
err nvm seems like there was something wrong with my dvi cable.
this monitor is simply STUNNING. I really notice the anti glare sparkle or anything.. seems fine to me. The size and color on this beast is making me speechless.

guys, i have been starring at this monitor too long to tell, but does anyone else think the white with my monitor seems slightly pinkish?
If you camera is rendering faithfully, it has no pink tendency. The screen next to it has a slight blue tendency so your 2711 may look pink in comparison.

ok, i think what happens is all my other monitors are a bit off calibration, thats why after looking at them for a while my u2711 seems weird in comparison.
I got the deal cuz i was lucky. bestdirect.ca had the monitor for 757, but it was a typo. I went to compu2000 (where they had the unit in store) and price matched it (compu2000,directcanada,bestdirect,and ncix are all actually under the same company). But the guy told me it was a typo and they changed the price while i was paying for mine.
