Unfortunately buggy ...

Update April 2015:
I have the score increased to 4 stars because of the below-mentioned bug has since been no further annoyance in everyday life. But of course, would still advise that Rev. A00 not to buy.
--------------------------------------

Update Sep.2013:
I am sorry to see that the monitor in Rev. A00 has a bug. The brightness remains after switching sometimes at very low levels, sometimes on a very bright (even though the same stage is always set). I need to think seriously about returning. Lt. another review on Amazon.com has this Rev. A00 also other problems that do not occur in version A02.

--------------------------------------

I am from the Dell U2413 been very enthusiastic. He replaced me also not a bad Benq XL2410T (16: 9, 120Hz), and gives a brief interlude with the Dell U2412M from. Reason for my new purchase was that I had with the 16: 9 format was not happy when working, and absolutely wanted 16:10 again.

I have to first buy the U2412M to which I have written a detailed review. Just In Time: this has the typical in this price range PWM backlight flickering on (strobe effect). People who suffer from eye pain front of the monitor, perhaps sensitive to this flicker. I know now that my has prepared a lot "headache", and have finally found a solution for it, namely the Dell U2413.

For U2413: outwardly I find the monitor very appealing. I can not fault at the processing. The peculiarities of the IPS panels have been addressed often enough. It seems to me here is out of proportion very quickly an elephant. The more one says, the greater seems to be the effect - so it went at least to me when reading the tests and reviews. I have my compared ca 5 year old 22 "-Samsung monitor with a TN panel considered:. The color changes in viewing angle changes are in direct comparison so blatant that my next any IPS glow or sparkle the appear completely meaningless I just see a great image of me.

The 16:10 is me far better than 16: 9. Although the difference objectively accounts for only about 2 inches in height, seems to me everything on the screen is now much larger and clearer. For productive work I can recommend only. Although the resolution of 1920x1200 is no longer top-of-the-line, here are now 2560x1440 or 2560x1600 possible it bothers me not at all. Maybe it's different when you're first used the higher resolution. But so far I'm from nothing and I can work well.

The U2413 can display a wider color gamut than about the U2412M, which is very important for graphic designers, photographers and in the print industry professionals. I work mainly text-based, so far as that is for me not a critical feature. You can select the monitor's color space to be displayed, and there you can see the difference between, for example, Adobe RGB, and the smaller, common in office monitors sRGB immediately. The colors in Adobe RGB will be much more intense, almost too intense for my taste. Therefore, I use sRGB, but the screen can definitely more!

The OSD menu keys are touch-sensitive (as opposed to Dell U2412M where they are normal push buttons). Here I must say that I had the keys of the U2412M almost a little better. The touch buttons are made but very chic. A proximity sensor on the bottom button light when one comes close to the finger. Then a light touch to "press" the appropriate button to suffice. There is nothing bad. For me personally the physical pressure was rather because it provides sensory feedback, and has always worked. The touch controls work well, but now and then a touch is not recognized - but that's really whine at the highest level. Otherwise, the OSD menu is super thoughtful. Through two shortcut buttons (which are freely assignable) one is with two touches in the main settings. No eternal By dumbbells through nested menu structures more. The keys have depending on the context dynamic functions that are shown on the display next to the button. So you also always know which key does what does - something that has made me the BenQ every now and then mad, where you never knew which button is now OK and Cancel which, where and where is Back After-ago.

The connectivity options are numerous and listed in the description. It is among others also a DisplayPort and a DVI cable. There is also the possibility to connect the monitor to a USB port on the PC, then you can attach eg mouse and keyboard directly to the monitor. There is furthermore a side SD card slot, whose function has not yet been opened up to me :-)

The most important advantage of the Dell U2413 is but for me the already mentioned, nonexistent PWM flicker of the LED backlight. This at first glance completely invisible effect is the fast rotating the wrist in front of the monitor. One then sees individual pictures (the more the brightness is reduced, the greater the effect occurs on), then the LEDs flicker. If you see a continuous gray track, then they light up constantly. For most people, that seems to make little difference. For me, and (as I of relevant reports and forums now know) many others but it is the cause of eye stress and headaches. Since manufacturers unfortunately nothing to write to the technical data sheets, one has to rely on reviews. The technically good tests address the issue PWM backlight today mostly already. I can work without eye problems with the U2413 finally. Where I previously just a few minutes before the Monitor had eye problems (Squinting, permanent looking away, general feeling of stress), I can now look relaxed on white areas on the screen. This is really something new, and clearly worth the extra price for me.
