Manager display Dell cannot see the second monitor in Windows 10

I have Dell monitors: a U2515H and a U2413. In Windows 7, Manager display has a drop down at the top allowing me to select each monitor. In Windows 19 (that I just installed), he went, I can change only brightness to one of my monitors.

I downloaded the latest version from here but no difference (in fact he told me that my current version is more recent).

Y at - it a software update in the works, or any manual fix I can do?

DDM requires more than a simple detection of the monitor - it requires a reliable * two-way * communication channel on the screen, where simply display something on the screen requires only a one-way link. If you check the DDM diagnostic log when you have a failed DP1.2 Garland, I think you'll find both monitors are detected, but we have a specific Windows error message that came through the display driver. The culprit will probably be of the 1st generation U2413.  This cannot be fixed by an update of the MDD.

Given that monitors DP1.2 1st generation have experienced problems with the DDC/CI, one thing to try is changing the physical configuration.

-Connect the U2515 directly on the map of AMD, and * allow * DP1.2 in the OSD U2515

-Connect the U2413 to the U2515, and * disable * DP1.2 in the OSD U2413.

  • Vista don't forget display settings; move the second monitor from top right.

    Windows Vista is often (not always) forgotten my display settings for my external monitor.

    I have a Dell XPS M1530 laptop with a NVIDIA GeForce 8600 M GT graphics card.  The laptop is running Vista Home Premium SP2 with all updates applied.  I have a Samsung LCD monitor mounted on the wall above the laptop screen that I use as a second monitor (driven by the output of the laptop).

    I updated the display settings so that my second screen is located above my main monitor. My problem is that Vista often forget this parameter after the standby or hibernation, and returns the value by default display settings of 'second monitor is to the right of the primary monitor'.  This means that I often walk in the display settings to do the right thing (pardon the pun).

    I've seen other messages to try to use 'View to connect' in the settings of Windows Mobile (win - X).  However this option only supports a second monitor is located on the left or the right of the main screen - not on it.

    ==================================

    You may need to update your display and video driver

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded: run DriverView - define the VIEW
    for the drivers Microsoft hide - updated those without drain in their names. (Also updated
    the BIOS and chipset drivers.)

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, this leaves ONE of Windows updates, but it will not install the drivers who will be generally
    be older and cause problems. If updates offers a new driver and then HIDE it (right click on it) and
    Then, get new ones manually if you wish.

  • the taskbar appears on the second monitor

    I have a DELL XPS M1530 laptop with a GT GeForce 8600 M adapter and a second monitor running Windows Vista (fully updated). It has worked very well for more than eight months. Recently, I added a second user.

    Now, when the second user shuts down the computer and I have the later start, the taskbar will appear on monitor two. Under normal circumstances, the other user has the taskbar on the screen one (as I was). I checked and the laptop display is set to monitor a.

    How can I get the taskbar on the laptop screen when this happens?

    I tried this and many other things. The problem kept coming back without rhyme or reason. Then, one day, it just stopped happening.

  • U2414H, Dual, laptop, Windows 10, Nvidia GTX 960 M, no STDS to the second monitor?

    Hi all

    I hope that I have included all relevant information in the present, but ask if I missed something. I bought two of the screens U2414H and a Windows 10 laptop computer powered by GTX 960 M with HDMI and Mini DP ports. My goal was to be able to the Garland of the whole U2414H screens so I could use my laptop out and about, and when connection back to the monitors of would have to plug in a cable and get two screens. In theory, but...

    I followed the instructions and using two Mini-DP to DP cables, connected the mini laptop RFP RFP on the first screen. DP on this same screen highlights Mini DP on the second monitor. I activated the DisplayPort 1.2 on both of these screens. I can't get any signal on the second monitor, it boils down to the power saving mode.

    Otherwise, I decided I would try using two cables and ditch the idea of DP STD I can at least use the two screens. So I have laptop HDMI to a screen and the MiniDP to another, and therefore, that alone will never work at a time. Individually, they work very well, both with HDMI or DP. But the two connection fails every time. When I tried to connect a display of alternative supporting HDMI as the second, which works very well.

    So I had an autour reading and it seems that it is common to have problems of connectivity to these screens. This brings me well on my two questions:

    (1) is there something that would work?

    (2) assuming that there is nothing that works, Dell can swap these screens for two that will achieve what I need?

    Thank you

    Dave

    In MST, DP 1.2 should be turned off (disabled) on the second monitor.

    Laptop AMD on--> U2414H CDM to cable DP--> DP U2414H #1 in (DP 1.2 enabled) (Port #3 in the image)


    #1 U2414H (Port #5 in photo) DP--> DP U2414H CDM cable--> 2 # U2414H CDM in (DP 1.2 disabled) (Port #4 in photo)

    When you use only no STDS, is the lid of the laptop open all trying to run two monitors of U2414H? This laptop can even run three screens, laptop LCD + 1 # U2414H + 2 # U2414H?

  • Display behavior incorrectly on the second screen in portrait mode?

    I use a graphics card from Nvidia GeForce 9400GT with two monitors (the two resolution 1600 x 1200). When the second monitor is in portrait mode, the contents of the window of Firefox are not correctly. This problem does not always occur, but when it does it persists as long as the computer is running (that is, between stops). The dysfunction of graph is displayed when the window is moved laterally, which case the contents don't follow the window correctly. This occurs if the "Show while dragging the content" is enabled or disabled.

    Try turning off hardware acceleration.

    • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

    If disable hardware acceleration works then check if there is an update available for your graphics display driver.

  • Scrolling Web page very slow on the second monitor

    I have two monitors. When I move the window of firefox for the second monitor - scrolling of web pages is very slow. Sometimes he computer freeze (I can't move the mouse cursor).
    I checked the other applications such as MS Word, Chrome.
    This problem is only firefox problem.

    This problem apears when the part of the firefox window shows on the second monitor (or even 50 pixels)

    Hey, I had the same problem and I solved it:
    1. - in the Firefox menu, display the Tools/Options.
    2. - unselect the checkbox "use hardware acceleration when available.
    This should work better now. Apparently the hardware acceleration makes the problems only when the windows of Firefox appears in a non-primary screen (don't know why). I suppose you know, but if you want to change your primary monitor you can do it from settings (right click on the desktop, then properties).
    Good luck!
