Hello, I bought the monitor U2412M some time ago and am very satisfied. I would like to ask something thouh. I always use the power button / stop to turn it on when I turn on my PC and it turns off when I turn my PC off. Should I just leave it on all the time so that things would turn out when I turn on the main switch for my power outlet (which feeds my PC, monitor and other devices)? Could monitor will suffer such use ok that would be OK? Thank you! :)


Hi Bellzemos,

When you turn off the computer, the monitor goes into stand by mode. The monitor consumes negligible energy in stand mode.

When you turn off the power, the monitor turns off completely. When you switch on the network once again, if the previous status of the monitor was on, it will start automatically without having to press the power button on it.

I suggest you connect your computer and the monitor to a surge protector in order to avoid any damage due to a power surge.

I hope this helps.

  • U2412M, is no longer recognized by Windows 10?


    I have a Dell XPS and two monitors Dell, a U2412M and a U2415. Yesterday, I had to do a Windows 10 reset due to a software problem. However, now 10 Windows recognizes only the U2415. The U2412M he sees as a generic PnP monitor and sets a horrible resolution of 640 x 480, which is unusable.  Previously both monitors worked fine on Windows 10. I spent much of yesterday with the support staff of Microsoft, without success.  I can't find a Windows 10 driver for this monitor.  I know that I probably should have checked for a first driver, but I can't say that I have never had a problem with a monitor when changing the operating system.

    Any suggestions?


    I had exactly the same problem. I use Win 10 and U2412M for 9 months without problem and then all of a sudden a couple of days resolution has been reset and he used the generic PnP Monitor driver. Further details on a post I did in Windows Secrets Lounge at the link below:


    I finally fixed it by swapping CPU of VGA/DVI monitor connection using the lower connector on the CPU. I rebooted and immediately returned to the correct resolution.

  • Where can I download DUCCS to calibrate the screens U2415 and U2412M?

    Hi, I would like to calibrate two monitors, a new U2415 and a three or four-year-old U2412M. I saw the documentation for a tool of Reference called Dell Dell Ultrasharp Color Calibration System (DUCCS), but I am unable to find a download for it on the Dell site page - other links I found simply go to the launch of Dell support page.

    The oldest set U2412M to the point an artifact pronounced as a task of water on the right side (as U2412M that guy) and it moved slightly purple. The new U2415 seems that it might be a bit too yellow. They are quite different side-by-side, and I would be recognizing a tool that can help me calibrate the two as well as possible.

    Thank you!

  • Double U2412m installation on an edition of founders of MSI GeForceGTX 1080


    Is it possible to connect two monitors u2412m to the graphics card MSI 1080 FE with two DisplayPort cables. The monitor has a DP, but I don't know how it works. The video card has the following products: x 3 (Version 1.4) of DisplayPort / HDMI (Version 2.0) / DL-DVI-D

    How this configuration? What kind of cables/adapters are to be provided?

    Thank you!

    Hi softerthansteel,

    You can just use normal cables DisplayPort for touch screens, so one cable for each monitor to the graphics card. Another option would be to HDMI/DVI (for one of the cables because the card is 2.0 and the other DisplayPort, but I recommend you stick with the DisplayPort cables). The card will have no problem to drive the two U2412M for etc. Extended desktop.

    I hope this helps.

    I just bought a DELL U2412M monitor, but have problems with its brightness settings. I found extremely bright, can't spend too much time in front of him without having headaches, at the present time, this monitor is useless for me. If I decrease the brightness of the Panel, it helps a little, but only if the brightness is of ~ 10, which is too low to produce a screen the user can enjoy. Do you have any suggestions?

    Already talk to the Dell Support without any solution they told me it was a problem with the docking station you have version 1.0 of DP and our monitors 1.2 DP which does not. I don't want to believe this response. Sometimes, when I installed a different video driver 3 display will light for a few seconds, but after installation always the same problem.

I looked on this topic on many forums and cable mini display port seems the most recommended. I realize that Dell does not test its products with Apple devices, but any advice on the best way to attach your monitor for my Mac mini would be useful.

  • Application of monitor Dell DDM with U2515H and U2412M dual screen setup and USB drive menu


    I have U2515H and U2412M independently connected with DP cable to GTX960 video card.

    Two questions;


    I have the latest driver display and the last Application of monitor Dell DDM.  It detects U2515H OK but not U2412M.   necessary on the menu OSD is activated but still no go.    Is - this known issue?


    Also with U2515H, curiously section USB tab energy on screen Menu (the one who press the button) is grayed out.  Can not choose how the power of USB hub behave when the screen goes into sleep mode?    What cause this menu to be grayed out?    Factory reset has no effect on this menu item.

    Be aware that U2515H has been replaced by Dell last Friday with monitor construction January because the one originally, I got a defect on the bezel mounting, but this USB menu was selectable.   It was built in April/205.

    Thanks for the research.

    (Updated the model type edition only)

    There is no U2414M. Do you mean the U2412M? If so, the U2412M is not supported. It was an error in the web. DDM requires a year of Dell 2013 model year or newer.

    There is no U25125H or U2525H. Do you mean the U2515H? From the U2515H Manual page 41 =
    Allows you to enable or disable the USB function standby monitor.

    NOTE: USB power standby mode is available only when the USB upstream cable is disconnected. This option will be grayed out when the USB cable upstream traffic in.

  • P2815Q, U2412M, Surface Pro 3 + Dock. Flickering U2412M

    Hello - my setup below =

    -Surface Pro 3 (i7, intel hd 5000 video) - connected to surface P2815Q pro 3 dock mini DisplayPort / on monitor (display size full port)

    -Monitor P2815Q 4 k (surface pro 3 dock - using display port output daisy chain U2412M)

    -Monitor U2412m (connected via the displayport P2815Q display port out)

    My first question was that I could not display port on the P2815Q of work - until I chose the menu on the monitor and the displayport 1.2 setting turned on.  Now the output on the P2815Q dp port feeds the U2412M.

    Now, my problem is that when I remove the surface and re-dock - the U2412M sparkles. I can solve the problem of flicker by unplugging the power cord of the U2412M (last of the closed string) and plug back. It's almost as if there is some type of sync problem.

    Any thoughts or ideas?
    Any help is appreciated!

  • U2412M - all white becomes bright yellow

    Just bought a new monitor and am having a strange problem. When I attach my computer monitor (IBM laptop computer T61p, Intel 965 chip graphics card, VGA hook up with the cable supplied with the new monitor) and boot, what would normally be white becomes bright yellow. (Is not like the yellow tint problem, some people have, it's pure, saturated yellow.) Sometimes even the text of the MESSAGE, so it can not because of the OS. (OpenSuSE 13.1). Yet, if I connect the VGA cable to my old monitor (Dell 2001FP) and start and then exchange the work cable to the new, I get white normal and just need to use xrandr to reset the display. So it can't really be a failure to monitor, can it? (And shows the monitor self test all colors properly, as do the messages and messages on the screen. I'm at a loss as to what could be the cause. I really like the monitor when the colors are good, but I won't be swapping cables whenever I start. Any suggestions?

  • U2412M, CCFL or white LED?

    Go to calibrate the monitor using X-Rite ColorMunki Display. Just do not know what setting am I suppose to select during calibration. Use the U2412M CCFL or LED white?

    All monitors with ol ' very close to sRGB or smaller gamut backlight and standard gamut are "CCFL".

    All monitors with LED backlight and the standard range (very close to sRGB) are WLED (white led, it is a blue led with phosphor which take the blue light and glow in yelow, thast how white WLED is done)

    All THE new models with the standard range or laptops monitors are WLED: Inspiron 7000 13, U2412M, U2414H, P2414H, U2713HM, U2415, U2715... Led backlight monitor Dell 5 k and I think that gamut sRGB so here's a WLED too.

    A monitor with GB - LED backlight (family of the RG_phosphor in Xrites names) are widegamut monitor with 99% AdobeRGB cover and Red range beyond AdobeRGB. It is made with one blue and one green light and phosphores enjoy this light that illuminates in red. These are monitors for photography as U2413, U2713H, U3014, UP2414Q and UP3212Q

    A screen with backlight RGB is a very expensive monitor with a plu gamut tah AdobeRGB. They are not used in the new models because they are expensive to manufacture so GB - LED is chosen for new widegamut monitors.

    If you could spend a litle of your time to read the documentation ArgyllCMS/DispcaGUI I recommend that you USE these programs, not Xrites color munki software. They are free software (code and binaries) and are most porwerful and i1Profiler accurate by far than software color munki or even. No driver is necessary i1DisplayPro or Munki Display. Just plug, open DispcalGUI, sleec your spectral correction (WLED, as in software from Xrite) and configure your calibration target.
    A lot of topics in this sub-forum of monitors about the calibration of GPU U2413/U2713H with DispcalUI not suitable for other monitors, remember that instead of RG_phosphor spectral correction you need to apply the correction WLED
